## What is cache busting?
|
|
|
|
To optimise network load time, browsers cache static files. Caching
|
|
greatly improves performance but how do you inform browsers to
|
|
invalidate cache when your files have changed?
|
|
|
|
Cache busting is a simple but effective solution for this issue. There
|
|
are several ways to achieve this but the way this library does this is
|
|
by changing file names to include the hash of the files' contents.
|
|
|
|
So if you have `bundle.js`, it will become
|
|
`bundle.<long-sha256-hash>.js`. This lets you set a super long cache age
|
|
as, because of the file names changing, the path to the filename, too,
|
|
will change. So as far as the browser is concerned, you are trying to load
|
|
a file that it doesn't have. Pretty neat, isn't it?
|
|
|
|
## Features
|
|
|
|
- [x] `SHA-256` based name generation during compile-time
|
|
- [x] Processes files based on provided MIME filters
|
|
- [x] Exclude certain files from processing based on file extensions
|
|
and/or file paths
|
|
- [x] Exposes modified names to program during runtime
|
|
- [x] Route prefixes(optional)
|
|
|
|
## Usage:
|
|
|
|
Add this to your `Cargo.toml`:
|
|
|
|
```toml
|
|
libcachebust = 0.2
|
|
```
