# GraphQL API
|
|
|
|
GraphQL APIs are different from [RESTful APIs](restful_api_styleguide.md). Reference
|
|
information is generated in our [GraphQL reference](../../api/graphql/reference/index.md).
|
|
|
|
However, it's helpful to include examples on how to use GraphQL for different
|
|
*use cases*, with samples that readers can use directly in the
|
|
[GraphiQL explorer](../api_graphql_styleguide.md#graphiql).
|
|
|
|
This section describes the steps required to add your GraphQL examples to
|
|
GitLab documentation.
|
|
|
|
## Add a dedicated GraphQL page
|
|
|
|
To create a dedicated GraphQL page, create a new `.md` file in the
|
|
`doc/api/graphql/` directory. Give that file a functional name, such as
|
|
`import_from_specific_location.md`.
|
|
|
|
## Start the page with an explanation
|
|
|
|
Include a page title that describes the GraphQL functionality in a few words,
|
|
such as:
|
|
|
|
```markdown
|
|
# Search for [substitute kind of data]
|
|
```
|
|
|
|
Describe the search. One sentence may be all you need. More information may
|
|
help readers learn how to use the example for their GitLab deployments.
|
|
|
|
## Include a procedure using the GraphiQL explorer
|
|
|
|
The GraphiQL explorer can help readers test queries with working deployments.
|
|
Set up the section with the following:
|
|
|
|
- Use the following title:
|
|
|
|
```markdown
|
|
## Set up the GraphiQL explorer
|
|
```
|
|
|
|
- Include a code block with the query that anyone can include in their
|
|
instance of the GraphiQL explorer:
|
|
|
|
````markdown
|
|
```graphql
|
|
query {
|
|
<insert queries here>
|
|
}
|
|
```
|
|
````
|
|
|
|
- Tell the user what to do:
|
|
|
|
```markdown
|
|
1. Open the GraphiQL explorer tool in the following URL: `https://gitlab.com/-/graphql-explorer`.
|
|
1. Paste the `query` listed above into the left window of your GraphiQL explorer tool.
|
|
1. Select **Play** to get the result shown here:
|
|
```
|
|
|
|
- Include a screenshot of the result in the GraphiQL explorer. Follow the naming
|
|
convention described in the [Save the image](styleguide/index.md#save-the-image) section of the Documentation style guide.
|
|
- Follow up with an example of what you can do with the output. Make sure the
|
|
example is something that readers can do on their own deployments.
|
|
- Include a link to the [GraphQL API resources](../../api/graphql/reference/index.md).
|
|
|
|
## Add the GraphQL example to the global navigation
|
|
|
|
You should include a link for your new document in the global navigation (the list on the
|
|
left side of the documentation website). To do so, open a second MR, against the
|
|
[GitLab documentation repository](https://gitlab.com/gitlab-org/gitlab-docs/).
|
|
|
|
We store our global navigation in the [`navigation.yaml`](https://gitlab.com/gitlab-org/gitlab-docs/-/blob/main/content/_data/navigation.yaml) file, in the
|
|
`content/_data` subdirectory. You can find the GraphQL section under the
|
|
following line:
|
|
|
|
```yaml
|
|
- category_title: GraphQL
|
|
```
|
|
|
|
Be aware that CI tests for that second MR will fail with a bad link until the
|
|
main MR that adds the new GraphQL page is merged. Therefore, only merge the MR against the
|
|
[`gitlab-docs`](https://gitlab.com/gitlab-org/gitlab-docs) repository after the content has
|
|
been merged and live on `docs.gitlab.com`.
