GraphQL API
Pupilfirst LMS uses a GraphQL API to enable typed communication between the ReScript front-end code and the Rails server. A few of these GraphQL queries and mutations can be accessed using token-based authentication.
Documentation#
Documentation for queries and mutations that are accessible via token-based authentication can be found here: https://pupilfirst.github.io/pupilfirst-api-docs
Token-based authentication#
To generate a token on a self-hosted instance, simply call the user.regenerate_api_token method, and read the token
by calling user.api_token. Make sure to save the token in your application's configuration; it cannot be accessed
again from the database.
To authenticate using the token, pass the token in the Authorization header:
Browsing GraphQL in development#
Visit the /graphiql path to browse and interact with all GraphQL queries in the development environment.
Updating GraphQL schema#
If you make any changes to the GraphQL schema, you'll need to update the graphql_schema.json file by running an
introspection query.
With the Pupilfirst server running, run the graphql-codegen script.
It'll visit the local GraphQL end-point which is configured in the codegen.yml file, fetch the schema and store it in
the graphql_schema.json file.
