This is a GraphiQL plugin for Sphinx that lets you make GraphQL queries from your docs.
We built this for documenting Hasura GraphQL engine's API. Check it out in action here. (Note: In our docs we have added custom css overrides to make GraphiQL look as per our needs)
To insert a GraphiQL component inside your .rst doc, use the declarative:
.. graphiql::
:query:
query {
author {
id
name
}
}If you want to make GraphiQL view-only (ie: disable execution), you just have to add another option :view_only:. For example:
.. graphiql::
:view_only:
:query:
query {
author {
id
name
}
}Sometimes you will want to show the response along with the query without executing it. You can do that by adding a :response: option.
.. graphiql::
:view_only:
:query:
query {
author {
id
name
}
}
:response:
{
"data": {
"author": [
{
"id": 1
"name": "Justin",
},
{
"id": 2
"name": "Beltran",
},
{
"id": 3
"name": "Sidney",
}
]
}
}By default, the GraphQL endpoint is picked up from an environment variable as described here.
In case you want to explicitly set an endpoint for a query, you can do so by adding an :endpoint: option.
.. graphiql::
:endpoint: http://localhost:8080/v1/graphql
:query:
query {
author {
id
name
}
}$ pip install sphinx_graphiqlYou might be using other extensions in your docs. Append sphinx_graphiql to the list of extensions.
extensions.append('sphinx_graphiql')
Add the following tags inside the <head></head> of your template html file (typically layout.html).

fetcher: graphQLFetcher(endpoint),
schema: null, // TODO: Pass undefined to fetch schema via introspection
query: query,
response: response
});
ReactDOM.render(graphiQLElement, target);
}

// if graphiql elements present, setup graphiql
if (document.getElementsByClassName('graphiql').length > 0) {
setupGraphiQL();
}
</script>You can find these tags at
static/static.htmlof the root directory.
You have to set the GraphQL endpoint as an environment variable in your sphinx configuration file (typically conf.py at the root your your project).
For example:
GRAPHIQL_DEFAULT_ENDPOINT = "https://graphql.my-graphql-app.io/v1/graphql"GraphiQL uses the GraphQL schema to auto complete as you type in queries and mutations.
If your GraphQL endpoint supports introspection, just pass undefined as the schema variable and
auto-completion will work out of the box.
const graphiQLElement = React.createElement(GraphiQL, {
fetcher: graphQLFetcher(endpoint),
schema: undefined, // the schema will be fetched using introspection
query: query,
response: response
});
