-Contributing code to hydrogen-web
-==================================
-
-Everyone is welcome to contribute code to hydrogen-web, provided that they are
-willing to license their contributions under the same license as the project
-itself. We follow a simple 'inbound=outbound' model for contributions: the act
-of submitting an 'inbound' contribution means that the contributor agrees to
-license the code under the same terms as the project's overall 'outbound'
-license - in this case, Apache Software License v2 (see
-[LICENSE](LICENSE)).
-
-How to contribute
------------------
-
-The preferred and easiest way to contribute changes to the project is to fork
-it on github, and then create a pull request to ask us to pull your changes
-into our repo (https://help.github.com/articles/using-pull-requests/)
-
-We use GitHub's pull request workflow to review the contribution, and either
-ask you to make any refinements needed or merge it and make them ourselves.
-
-Things that should go into your PR description:
- * References to any bugs fixed by the change (in GitHub's `Fixes` notation)
- * Describe the why and what is changing in the PR description so it's easy for
-   onlookers and reviewers to onboard and context switch.
- * If your PR makes visual changes, include both **before** and **after** screenshots
-   to easily compare and discuss what's changing.
- * Include a step-by-step testing strategy so that a reviewer can check out the
-   code locally and easily get to the point of testing your change.
- * Add comments to the diff for the reviewer that might help them to understand
-   why the change is necessary or how they might better understand and review it.
-
-We use continuous integration, and all pull requests get automatically tested:
-if your change breaks the build, then the PR will show that there are failed
-checks, so please check back after a few minutes.
-
-Tests
------
-If your PR is a feature then we require that the PR also includes tests.
-These need to test that your feature works as expected and ideally test edge cases too.
-
-Tests are written as unit tests by exporting a `tests` function from the file to be tested.
-The function returns an object where the key is the test label, and the value is a 
-function that accepts an [assert](https://nodejs.org/api/assert.html) object, and return a Promise or nothing.
-
-Note that there is currently a limitation that files that are not indirectly included from `src/platform/web/main.js` won't be found by the runner.
-
-You can run the tests by running `yarn test`.
-This uses the [impunity](https://github.com/bwindels/impunity) runner.
-
-We don't require tests for bug fixes.
-
-In the future we may formalise this more.
-
-Code style
-----------
-The js-sdk aims to target TypeScript/ES6. All new files should be written in
-TypeScript and existing files should use ES6 principles where possible.
-
-Please disable any automatic formatting tools you may have active.
-If present, you'll be asked to undo any unrelated whitespace changes during code review.
-
-Members should not be exported as a default export in general.
-In general, avoid using `export default`.
-
-The remaining code-style for hydrogen is [in the process of being documented](codestyle.md), but
-contributors are encouraged to read the
-[code style document for matrix-react-sdk](https://github.com/matrix-org/matrix-react-sdk/blob/master/code_style.md)
-and follow the principles set out there.
-
-Please ensure your changes match the cosmetic style of the existing project,
-and ***never*** mix cosmetic and functional changes in the same commit, as it
-makes it horribly hard to review otherwise.
-

------------
-If you change or create a file, feel free to add yourself to the copyright holders
-in the license header of that file.

+Hydrogen is deployed to [hydrogen.element.io](https://hydrogen.element.io). You can run it locally `yarn install` (only the first time) and `yarn start` in the terminal, and point your browser to `http://localhost:3000`. If you prefer, you can also [use docker](doc/docker.md).
 
- 1. Download the [latest release package](https://github.com/vector-im/hydrogen-web/releases).
- 1. Extract the package to the public directory of your web server.
- 1. If this is your first deploy:
-    1. copy `config.sample.json` to `config.json` and if needed, make any modifications (unless you've set up your own [sygnal](https://github.com/matrix-org/sygnal) instance, you don't need to change anything in the `push` section).
-    1. Disable caching entirely on the server for:
-        - `index.html`
-        - `sw.js`
-        - `config.json`
-        - All theme manifests referenced in the `themeManifests` of `config.json`, these files are typically called `theme-{name}.json`.
-
-        These resources will still be cached client-side by the service worker. Because of this; you'll still need to refresh the app twice before config.json changes are applied.
-
-## Set up a dev environment
-
-You can run Hydrogen locally by the following commands in the terminal:
-
- - `yarn install` (only the first time)
- - `yarn start` in the terminal
-
-Now point your browser to `http://localhost:3000`. If you prefer, you can also [use docker](doc/docker.md).

-# Hydrogen View SDK
+# How to use Hydrogen as an SDK
 
+If you want to use end-to-end encryption, it is recommended to use a [supported build system](../src/sdk/paths/) (currently only vite) to be able to locate the olm library files.
 
-The Hydrogen view SDK allows developers to integrate parts of the Hydrogen application into the UI of their own application. Hydrogen is written with the MVVM pattern, so to construct a view, you'd first construct a view model, which you then pass into the view. For most view models, you will first need a running client.
+**NOTE**: For now, these instructions will only work at development time, support when building (e.g. `vite build`) is being worked on and tracked in [#529](https://github.com/vector-im/hydrogen-web/issues/529).
 
-## Example
-
-The Hydrogen SDK requires some assets to be shipped along with your app for things like downloading attachments, and end-to-end encryption. A convenient way to make this happen is provided by the SDK (importing `hydrogen-view-sdk/paths/vite`) but depends on your build system. Currently, only [vite](https://vitejs.dev/) is supported, so that's what we'll be using in the example below.
-
-You can create a vite project using the following commands:
+You can create a project using the following commands
 
 ```sh
 # you can pick "vanilla-ts" here for project type if you're not using react or vue
 yarn create vite
 cd <your-project-name>
 yarn
-yarn add hydrogen-view-sdk
+yarn add https://github.com/vector-im/hydrogen-web.git
 ```
 
-You should see a `index.html` in the project root directory, containing an element with `id="app"`. Add the attribute `class="hydrogen"` to this element, as the CSS we'll include from the SDK assumes for now that the app is rendered in an element with this classname.
-
-If you go into the `src` directory, you should see a `main.ts` file. If you put this code in there, you should see a basic timeline after login and initial sync have finished (might take a while before you see anything on the screen actually).
-
-You'll need to provide the username and password of a user that is already in the [#element-dev:matrix.org](https://matrix.to/#/#element-dev:matrix.org) room (or change the room id).

-## Typescript support
-
-Typescript support is not yet available while we're converting the Hydrogen codebase to Typescript.
-In your `src` directory, you'll need to add a `.d.ts` (can be called anything, e.g. `deps.d.ts`)
-containing this snippet to make Typescript not complain that `hydrogen-view-sdk` doesn't have types:
-
-```ts
-declare module "hydrogen-view-sdk";

-## API Stability
-
-This library follows semantic versioning; there is no API stability promised as long as the major version is still 0. Once 1.0.0 is released, breaking changes will be released with a change in major versioning.

-## Third-party licenses
-
-This package bundles the bs58 package ([license](https://github.com/cryptocoinjs/bs58/blob/master/LICENSE)), and the Inter font ([license](https://github.com/rsms/inter/blob/master/LICENSE.txt)).

-# Theming Documentation
-## Basic Architecture
-A **theme collection** in Hydrogen is represented by a `manifest.json` file and a `theme.css` file.
-The manifest specifies variants (eg: dark,light ...) each of which is a **theme** and maps to a single css file in the build output.
-
-Each such theme is produced by changing the values of variables in the base `theme.css` file with those specified in the variant section of the manifest:
-
-![](images/theming-architecture.png)
-
-More in depth explanations can be found in later sections.
-
-## Structure of `manifest.json`
-[See theme.ts](../src/platform/types/theme.ts)
-
-## Variables
-CSS variables specific to a particular variant are specified in the `variants` section of the manifest:
-```json=
- "variants": {
-     "light": {
-         ...
-         "variables": {
-             "background-color-primary": "#fff",
-             "text-color": "#2E2F32",
-         }
-     },
-      "dark": {
-         ...
-        "variables": {
-            "background-color-primary": "#21262b",
-            "text-color": "#fff",
-        }
-    }
- }
-```
-
-These variables will appear in the css file (theme.css):
-```css=
-body {
-    background-color: var(--background-color-primary);
-    color: var(--text-color);
-}
-```
-
-During the build process, this would result in the creation of two css files (one for each variant) where the variables are substitued with the corresponding values specified in the manifest:
-
-*element-light.css*:
-```css=
-body {
-    background-color: #fff;
-    color: #2E2F32;
-}
-```
-
-*element-dark.css*:
-```css=
-body {
-    background-color: #21262b;
-    color: #fff;
-}
-```
-
-## Derived Variables
-In addition to simple substitution of variables in the stylesheet, it is also possible to instruct the build system to first produce a new value from the base variable value before the substitution.
-
-Such derived variables have the form `base_css_variable--operation-arg` and can be read as:
-apply `operation` to `base_css_variable` with argument `arg`.
-
-Continuing with the previous example, it possible to specify:
-```css=
-.left-panel {
-    /* background color should be 20% more darker
-       than background-color-primary */
-    background-color: var(--background-color-primary--darker-20);
-}
-```
-
-Currently supported operations are:
-
-| Operation | Argument | Operates On |
-| -------- | -------- | -------- |
-| darker     | percentage | color |
-| lighter     | percentage | color |
-
-## Aliases
-It is possible give aliases to variables in the `theme.css` file:
-```css=
-:root {
-    font-size: 10px;
-    /* Theme aliases */
-    --icon-color: var(--background-color-secondary--darker-40);
-}
-```
-It is possible to further derive from these aliased variables:
-```css=
-div {
-    background: var(--icon-color--darker-20);
-    --my-alias: var(--icon-color--darker-20);
-    /* Derive from aliased  variable */
-    color: var(--my-alias--lighter-15);
-}
-```
-
-
-## Colorizing svgs
-Along with a change in color-scheme, it may be necessary to change the colors in the svg icons and images. 
-This can be done by supplying the preferred colors with query parameters:
-`my-awesome-logo.svg?primary=base-variable-1&secondary=base-variable-2`  
-
-This instructs the build system to colorize the svg with the given primary and secondary colors.
-`base-variable-1` and `base-variable-2` are the css-variables specified in the `variables` section of the manifest.
-
-For colorizing svgs, the source svg must use `#ff00ff` as the primary color and `#00ffff` as the secondary color:
-
-  
-
-| ![](images/svg-icon-example.png) | ![](images/coloring-process.png) |
-| :--: |:--: |
-| **original source image** | **transformation process** |
-
-## Creating your own theme variant in Hydrogen
-If you're looking to change the color-scheme of the existing Element theme, you only need to add your own variant to the existing `manifest.json`.
-
-The steps are fairly simple:
-1. Copy over an existing variant to the variants section of the manifest.
-2. Change `dark`, `default` and `name` fields.
-3. Give new values to each variable in the `variables` section.
-4. Build hydrogen.
-
-## Creating your own theme collection in Hydrogen
-If a theme variant does not solve your needs, you can create a new theme collection with a different base `theme.css` file.
-1. Create a directory for your new theme-collection under `src/platform/web/ui/css/themes/`.
-2. Create `manifest.json` and `theme.css` files within the newly created directory.
-3. Populate `manifest.json` with the base css variables you wish to use.
-4. Write styles in your `theme.css` file using the base variables, derived variables and colorized svg icons.
-5. Tell the build system where to find this theme-collection by providing the location of this directory to the `themeBuilder` plugin in `vite.config.js`:
-```json=
-...
-themeBuilder({
-    themeConfig: {
-        themes: {
-            element: "./src/platform/web/ui/css/themes/element",
-            awesome: "path/to/theme-directory"
-        },
-        default: "element",
-    },
-    compiledVariables,
-}),
-...
-```
-6. Build Hydrogen.
-
-## Changing the default theme
-To change the default theme used in Hydrogen, modify the `defaultTheme` field in `config.json` file (which can be found in the build output):
-```json=
-"defaultTheme": {
-    "light": theme-id,
-    "dark": theme-id
-}
-```
-
-Here *theme-id* is of the form `theme-variant` where `theme` is the key used when specifying the manifest location of the theme collection in `vite.config.js` and `variant` is the key used in variants section of the manifest.
-
-Some examples of theme-ids are `element-dark` and `element-light`.  
-
-To find the theme-id of some theme, you can look at the built-asset section of the manifest in the build output.
-
-This default theme will render as "Default" option in the theme-chooser dropdown. If the device preference is for dark theme, the dark default is selected and vice versa.
-
-**You'll need to reload twice so that Hydrogen picks up the config changes!**
-
-# Derived Theme(Collection)
-This allows users to theme Hydrogen without the need for rebuilding. Derived theme collections can be thought of as extensions (derivations) of some existing build time theme. 
-
-## Creating a derived theme:
-Here's how you create a new derived theme:
-1. You create a new theme manifest file (eg: theme-awesome.json) and mention which build time theme you're basing your new theme on using the `extends` field. The base css file of the mentioned theme is used for your new theme.
-2. You configure the theme manifest as usual by populating the `variants` field with your desired colors.
-3. You add your new theme manifest to the list of themes in `config.json`.
-
-Refresh Hydrogen twice (once to refresh cache, and once to load) and the new theme should show up in the theme chooser.
-
-## How does it work?
-
-For every theme collection in hydrogen, the build process emits a runtime css file which like the built theme css file contains variables in the css code. But unlike the theme css file, the runtime css file lacks the definition for these variables:
-
-CSS for the built theme:
-```css
-:root {
-    --background-color-primary: #f2f20f;
-}
-
-body {
-    background-color: var(--background-color-primary);
-}
-```
-and the corresponding runtime theme:
-```css
-/* Notice the lack of definiton for --background-color-primary here! */
-body {
-    background-color: var(--background-color-primary);
-}
-```
-
-When hydrogen loads a derived theme, it takes the runtime css file of the extended theme and dynamically adds the variable definition based on the values specified in the manifest. Icons are also colored dynamically and injected as variables using Data URIs.

+## Introduce `abstract` & `override`
 
-## Use `type` rather than `interface` for named parameters and POJO return values.
-
-`type` and `interface` can be used somewhat interchangeably, but let's use `type` to describe data and `interface` to describe (polymorphic) behaviour.
-
-Good examples of data are option objects to have named parameters, and POJO (plain old javascript objects) without any methods, just fields.
-
-Also see [this playground](https://www.typescriptlang.org/play?#code/C4TwDgpgBACghgJwgO2AeTMAlge2QZygF4oBvAKCiqmTgFsIAuKfYBLZAcwG5LqATCABs4IAPzNkAVzoAjCAl4BfcuVCQoAYQAWWIfwzY8hEvCSpDuAlABkZPlQDGOITgTNW7LstWOR+QjMUYHtqKGcCNilHYDcAChxMK3xmIIsk4wBKewcoFRVyPzgArV19KAgAD2AUfkDEYNDqCM9o2IQEjIJmHT0DLvxsijCw-ClIDsSjAkzeEebjEIYAuE5oEgADABJSKeSAOloGJSgsQh29433nVwQlDbnqfKA)
-
-## Use `type foo = { [key: string]: any }` for types that you intend to fill in later.
-
-For instance, if you have a method such as:
-```js
-    function load(options) {
-        // ...
-    }
-```
-and you intend to type options at some later point, do:
-```ts
-    type Options = { [key: string]: any}
-```
-This makes it much easier to add the necessary type information at a later time.
-
-## Use `object` or `Record<string, any>` to describe a type that accepts any javascript object.
-
-Sometimes a function or method may genuinely need to accept any object; eg:
-```js
-function encodeBody(body) {
-    // ...
-}
-```
-In this scenario:
-- Use `object` if you know that you will not access any property
-- Use `Record<string, any>` if you need to access some property
-
-Both usages prevent the type from accepting primitives (eg: string, boolean...).  
-If using `Record`, ensure that you have guards to check that the properties really do exist.
+ - find all methods and getters that throw or are empty in base classes and turn into abstract method or if all methods are abstract, into an interface.
+ - change child impls to not call super.method and to add override
+ - don't allow implicit override in ts config

-## IView components
-
-The [interface](https://github.com/vector-im/hydrogen-web/blob/master/src/platform/web/ui/general/types.ts) adopted by view components is agnostic of how they are rendered to the DOM. This has several benefits:
- - it allows Hydrogen to not ship a [heavy view framework](https://bundlephobia.com/package/react-dom@18.2.0) that may or may not be used by its SDK users, and also keep bundle size of the app down.
- - Given the interface is quite simple, is should be easy to integrate this interface into the render lifecycle of other frameworks.
- - The main implementations used in Hydrogen are [`ListView`](https://github.com/vector-im/hydrogen-web/blob/master/src/platform/web/ui/general/ListView.ts) (rendering [`ObservableList`](https://github.com/vector-im/hydrogen-web/blob/master/src/observable/list/BaseObservableList.ts)s) and [`TemplateView`](https://github.com/vector-im/hydrogen-web/blob/master/src/platform/web/ui/general/TemplateView.ts) (templating and one-way databinding), each only a few 100 lines of code and tailored towards their specific use-case. They work straight with the DOM API and have no other dependencies.
- - a common inteface allows us to mix and match between these different implementations (and gradually shift if need be in the future) with the code.
-
-## Templates
-
-### Template language
-
-Templates use a mini-DSL language in pure javascript to express declarative templates. This is basically a very thin wrapper around `document.createElement`, `document.createTextNode`, `node.setAttribute` and `node.appendChild` to quickly create DOM trees. The general syntax is as follows:
-```js
-t.tag_name({attribute1: value, attribute2: value, ...}, [child_elements]);
-t.tag_name(child_element);
-t.tag_name([child_elements]);
-```
-**tag_name** can be [most HTML or SVG tags](https://github.com/vector-im/hydrogen-web/blob/master/src/platform/web/ui/general/html.ts#L102-L110).
-
-eg:
-Here is an example HTML segment followed with the code to create it in Hydrogen.
-```html
-<section class="main-section">
-    <h1>Demo</h1>
-    <button class="btn_cool">Click me</button>
-</section>
-```
-```js
-t.section({className: "main-section"},[
-    t.h1("Demo"), 
-    t.button({className:"btn_cool"}, "Click me")
-]);
-```
-
-All these functions return DOM element nodes, e.g. the result of `document.createElement`.
-
-### TemplateView
-
-`TemplateView` builds on top of templating by adopting the IView component model and adding event handling attributes, sub views and one-way databinding.
-In views based on `TemplateView`, you will see a render method with a `t` argument.  
-`t` is `TemplateBuilder` object passed to the render function in `TemplateView`. It also takes a data object to render and bind to, often called `vm`, short for view model from the MVVM pattern Hydrogen uses.
-
-You either subclass `TemplateView` and override the `render` method:
-```js
-class MyView extends TemplateView {
-    render(t, vm) {
-        return t.div(...);
-    }
-}
-```
-
-Or you pass a render function to `InlineTemplateView`:
-```js
-new InlineTemplateView(vm, (t, vm) => {
-    return t.div(...);
-});
-```
-
-**Note:** the render function is only called once to build the initial DOM tree and setup bindings, etc ... Any subsequent updates to the DOM of a component happens through bindings.
-
-#### Event handlers
-
-Any attribute starting with `on` and having a function as a value will be attached as an event listener on the given node. The event handler will be removed during unmounting.
-
-```js
-t.button({onClick: evt => {
-    vm.doSomething(evt.target.value);
-}}, "Click me");
-```
-
-#### Subviews
-
-`t.view(instance)` will mount the sub view (can be any IView) and return its root node so it can be attached in the DOM tree.
-All subviews will be unmounted when the parent view gets unmounted.
-
-```js
-t.div({className: "Container"}, t.view(new ChildView(vm.childViewModel)));
-```
-
-#### One-way data-binding
-
-A binding couples a part of the DOM to a value on the view model. The view model emits an update when any of its properties change, to which the view can subscribe. When an update is received by the view, it will reevaluate all the bindings, and update the DOM accordingly.
-
-A binding can appear in many places where a static value can usually be used in the template tree.
-To create a binding, you pass a function that maps the view value to a static value.
-
-##### Text binding
-
-```js
-t.p(["I've got ", vm => vm.counter, " beans"])
-```
-
-##### Attribute binding
-
-```js
-t.button({disabled: vm => vm.isBusy}, "Submit");
-```
-
-##### Class-name binding
-```js
-t.div({className: {
-    button: true,
-    active: vm => vm.isActive
-}})
-```
-##### Subview binding
-
-So far, all the bindings can only change node values within our tree, but don't change the structure of the DOM. A sub view binding allows you to conditionally add a subview based on the result of a binding function.
-
-All sub view bindings return a DOM (element or comment) node and can be directly added to the DOM tree by including them in your template.
-
-###### map
-
-`t.mapView` allows you to choose a view based on the result of the binding function:
-
-```js
-t.mapView(vm => vm.count, count => {
-    return count > 5 ? new LargeView(count) : new SmallView(count);
-});
-```
-
-Every time the first or binding function returns a different value, the second function is run to create a new view to replace the previous view.
-
-You can also return `null` or `undefined` from the second function to indicate a view should not be rendered. In this case a comment node will be used as a placeholder.
-
-There is also a `t.map` which will create a new template view (with the same value) and you directly provide a render function for it:
-
-```js
-t.map(vm => vm.shape, (shape, t, vm) => {
-    switch (shape) {
-        case "rect": return t.rect();
-        case "circle": return t.circle();
-    }
-})
-```
-
-###### if
-
-`t.ifView` will render the subview if the binding returns a truthy value:
-
-```js
-t.ifView(vm => vm.isActive, vm => new View(vm.someValue));
-```
-
-You equally have `t.if`, which creates a `TemplateView` and passes you the `TemplateBuilder`:
-
-```js
-t.if(vm => vm.isActive, (t, vm) => t.div("active!"));
-```
-
-##### Side-effects
-
-Sometimes you want to imperatively modify your DOM tree based on the value of a binding.
-`mapSideEffect` makes this easy to do:
-
-```js
-let node = t.div();
-t.mapSideEffect(vm => vm.color, (color, oldColor) => node.style.background = color);
-return node;
-```
-
-**Note:** you shouldn't add any bindings, subviews or event handlers from the side-effect callback,
-the safest is to not use the `t` argument at all.
-If you do, they will be added every time the callback is run and only cleaned up when the view is unmounted.
-
-#### `tag` vs `t`
-
-If you don't need a view component with data-binding, sub views and event handler attributes, the template language also is available in `ui/general/html.js` without any of these bells and whistles, exported as `tag`. As opposed to static templates with `tag`, you always use
-`TemplateView` as an instance of a class, as there is some extra state to keep track (bindings, event handlers and subviews).
-
-Although syntactically similar, `TemplateBuilder` and `tag` are not functionally equivalent.  
-Primarily `t` **supports** bindings and event handlers while `tag` **does not**. This is because to remove event listeners, we need to keep track of them, and thus we need to keep this state somewhere which
-we can't do with a simple function call but we can insite the TemplateView class.
-
-```js
-    // The onClick here wont work!!
-    tag.button({className:"awesome-btn", onClick: () => this.foo()});
-
-class MyView extends TemplateView {
-    render(t, vm){
-        // The onClick works here.
-        t.button({className:"awesome-btn", onClick: () => this.foo()});
-    }
-}
-```
-
-## ListView
-
-A view component that renders and updates a list of sub views for every item in a `ObservableList`.
-
-```js
-const list = new ListView({
-    list: someObservableList
-}, listValue => return new ChildView(listValue))
-```
-
-As items are added, removed, moved (change position) and updated, the DOM will be kept in sync.
-
-There is also a `LazyListView` that only renders items in and around the current viewport, with the restriction that all items in the list must be rendered with the same height.
-
-### Sub view updates
-
-Unless the `parentProvidesUpdates` option in the constructor is set to `false`, the ListView will call the `update` method on the child `IView` component when it receives an update event for one of the items in the `ObservableList`.
-
-This way, not every sub view has to have an individual listener on it's view model (a value from the observable list), and all updates go from the observable list to the list view, who then notifies the correct sub view.

-SDK:
-
- - we need to compile src/lib.ts to javascript, with a d.ts file generated as well. We need to compile to javascript once for cjs and once of es modules. The package.json looks like this:
-
-```
-"main": "./dist/index.cjs",
-  "exports": {
-    "import": "./dist/index.mjs",
-    "require": "./dist/index.cjs"
-  },
-  "types": "dist/index.d.ts",
-```
-
-we don't need to bundle for the sdk case! we might need to do some transpilation to just plain ES6 (e.g. don't assume ?. and ??) we could use a browserslist query for this e.g. `node 14`. esbuild seems to support this as well, tldraw uses esbuild for their build.
-
-one advantage of not bundling the files for the sdk is that you can still use import overrides in the consuming project build settings. is that an idiomatic way of doing things though?
-
-
-
-
-this way we will support typescript, non-esm javascript and esm javascript using libhydrogen as an SDK
-
-got this from https://medium.com/dazn-tech/publishing-npm-packages-as-native-es-modules-41ffbc0a9dea
-
-how about the assets?
-
-we also need to build the app
-
-we need to be able to version libhydrogen independently from hydrogen the app? as any api breaking changes will need a major version increase. we probably want to end up with a monorepo where the app uses the sdk as well and we just use the local code with yarn link?
-
-## Assets
-
-we want to provide scss/sass files, but also css that can be included
-https://github.com/webpack/webpack/issues/7353 seems to imply that we just need to include the assets in the published files and from there on it is the consumer of libhydrogen's problem.
-
-
-how does all of this tie in with vite?
-
-
-we want to have hydrogenapp be a consumer of libhydrogen, potentially as two packages in a monorepo ... but we want the SDK to expose views and stylesheets... without having an index.html (which would be in hydrogenapp). this seems a bit odd...?
-
-what would be in hydrogenapp actually? just an index.html file?
-
-I'm not sure it makes sense to have them be 2 different packages in a monorepo, they should really be two artifacts from the same directory.
-
-the stylesheets included in libhydrogen are from the same main.css file as is used in the app
-
-https://www.freecodecamp.org/news/build-a-css-library-with-vitejs/
-
-basically, we import the sass file from src/lib.ts so it is included in the assets there too, and we also create a plugin that emits a file for every sass file as suggested in the link above?
-
-we probably want two different build commands for the app and the sdk though, we could have a parent vite config that both build configs extend from?
-
-
-### Dependency assets
-our dependencies should not be bundled for the SDK case. So if we import aesjs, it would be up to the build system of the consuming project to make that import work.
-
-the paths.ts thingy ... we want to make it easy for people to setup the assets for our dependencies (olm), some assets are also part of the sdk itself. it might make sense to make all of the assets there part of the sdk (e.g. bundle olm.wasm and friends?) although shipping crypto, etc ...
-
-perhaps we should have an include file per build system that treats own assets and dep assets the same by including the package name as wel for our own deps:
-```js
-import _downloadSandboxPath from "@matrix-org/hydrogen-sdk/download-sandbox.html?url";
-import _serviceWorkerPath from "@matrix-org/hydrogen-sdk/sw.js?url"; // not yet sure this is the way to do it
-import olmWasmPath from "@matrix-org/olm/olm.wasm?url";
-import olmJsPath from "@matrix-org/olm/olm.js?url";
-import olmLegacyJsPath from "@matrix-org/olm/olm_legacy.js?url";
-
-export const olmPaths = {
-    wasm: olmWasmPath,
-    legacyBundle: olmLegacyJsPath,
-    wasmBundle: olmJsPath,
-};
-
-export const downloadSandboxPath = _downloadSandboxPath;
-```
-
-we could put this file per build system, as ESM, in dist as well so you can include it to get the paths
-
-
-## Tooling
-
- - `vite` a more high-level build tool that takes your index.html and turns it into optimized assets that you can host for production, as well as a very fast dev server. is used to have good default settings for our tools, typescript support, and also deals with asset compiling. good dev server. Would be nice to have the same tool for dev and prod. vite has good support for using `import` for anything that is not javascript, where we had an issue with `snowpack` (to get the prod path of an asset).
- - `rollup`: inlines 
- - `lerna` is used to handle multi-package monorepos
- - `esbuild`: a js/ts build tool that we could use for building the lower level sdk where no other assets are involved, `vite` uses it for fast dev builds (`rollup` for prod). For now we won't extract a lower level sdk though.
-
-
-## TODO
-
- - finish vite app build (without IE11 for now?)
- - create vite config to build src/lib.ts in cjs and esm, inheriting from a common base config with the app config
-    - this will create a dist folder with
-        - the whole source tree in es and cjs format
-        - an es file to import get the asset paths as they are expected by Platform, per build system
-        - assets from hydrogen itself:
-            - css files and any resource used therein
-            - download-sandbox.html
-        - a type declaration file (index.d.ts)
-
-## Questions
- - can rollup not bundle the source tree and leave modules intact?
-    - if we can use a function that creates a chunk per file to pass to manualChunks and disable chunk hashing we can probably do this. See https://rollupjs.org/guide/en/#outputmanualchunks
-
-    looks like we should be able to disable chunk name hashing with chunkFileNames https://rollupjs.org/guide/en/#outputoptions-object
-
-
-    we should test this with a vite test config
- 
-    we also need to compile down to ES6, both for the app and for the sdk

-InviteViewModel, RoomViewModel and RoomBeingCreatedViewModel are interchangebly used as "room view model":
-    - SessionViewModel.roomViewModel can be an instance of any
-    - RoomGridViewModel.roomViewModelAt(i) can return an instance of any
+InviteViewModel and RoomViewModel are interchangebly used as "room view model":
+    - SessionViewModel.roomViewModel can be an instance of either
+    - RoomGridViewModel.roomViewModelAt(i) can return an instance of either
 
 This is because they are accessed by the same url and need to transition into each other, in these two locations. Having two methods, especially in RoomGridViewModel would have been more cumbersome, even though this is not in line with how different view models are exposed in SessionViewModel.
 
 They share an `id` and `kind` property, the latter can be used to differentiate them from the view, and a `focus` method.
-Once we convert this folder to typescript, we should use this interface for all the view models:
-```ts
-interface IGridItemViewModel {
-    id: string;
-    kind: string;
-    focus();
-}
-```
