Below is some guidance on how to work on this project. If you have any questions, please feel free to open an issue.

Automated Tests

Our tests are written as a collection of fixture files located in src/tests/fixtures and src/tests/integrationFixtures. Each .ts file nested within this directory is a test case. The test runner will execute each test case and compare the output to corresponding .expected.ts file. If the output does not match the expected output, the test runner will fail.

The tests in src/tests/fixtures are unit tests that test the behavior of the extraction and code generation. They extract GraphQL SDL, generated schema.ts or any associated errors and code actions from the file and write that as output.

If the test includes a line like // Locate: User.name of // Locate: SomeType then the test runner will instead locate the given entity and write the location as output.

The tests in src/tests/integrationFixtures are integration tests that test the runtime behavior of the generated code. Each directory contains an index.ts file with @gql docblock tags which exports a root query class as the named export Query and a GraphQL query text under the named export query. The test runner will execute the query against the root query class and emit the returned response JSON as the test output.


pnpm run test

To run a specific test case, you can use the --filter flag and provide a substring match for the test fixture's path.

pnpm run test --filter=import

To update fixture files, you can use the --write flag.

pnpm run test --write

Interactive mode will prompt you to update the fixture files one by one for each failing fixture test.

pnpm run test --interactive

You an also get help with the CLI flags:

pnpm run test --help

All changes that affect the behavior of the tool, either new features of bug fixes, should include at least one new or changed fixture file.

Manual Tests

The code base includes a number of example servers that can be used to manually test features of the tool. To start the server, run the following command:

# Ensure you build grats first!

pnpm build
cd examples/yoga
pnpm install
pnpm run start

This will start a web server running GraphiQL which you can use to try out the server.

NPM Releases

GitHub CI publishes a release to npm for each commit. They use the version number convention 0.0.0-main-<git hash prefix>.

To publish a new release:

pnpm i
pnpm run build
pnpm version patch # or minor or major
pnpm publish
git push --tags
git push origin

You probably want to upgrade Grats in the Code Sandbox example:

https://capt.dev/grats-sandbox

NPM Auth Token

GitHub needs a special NPM token to be able to publish each commit's release. These expire regularly, so here's the steps to recreate them:

  1. Navigate to https://www.npmjs.com/settings/captbaritone/tokens and login
  2. Select the "Generate New Token" green button in the top left to spawn a dropdown
  3. Select "Granular Access Token"
  4. Fill in details
    • Package Scope: Read and Write, only select packages: Grats
    • Organizations: No access
  5. Select "Generate Token"
  6. Copy the token
  7. Navigate to https://github.com/captbaritone/grats/settings/environments/951200327/edit
  8. Scroll down to "Environment Secrets"
  9. Find the secret named NPM_TOKEN and click the "edit" icon
  10. Auth with security device as needed
  11. PAste in the token you copied in step 6
