The Linear Client uses custom [GraphQL Code Generator](https://graphql-code-generator.com/) plugins to produce a typed SDK for all operations and models exposed by the Linear production API.

### Structure

This monorepo uses `yarn workspaces` and `lerna` to publish packages.

Generated code uses file prefix `_generated` and should never be manually updated.

Open source packages:
- [sdk](https://github.com/linear/linear/tree/master/packages/sdk/README.md) - The Linear Client SDK for interacting with the Linear GraphQL API
- [import](https://github.com/linear/linear/tree/master/packages/import/README.md) - Import tooling for uploading from other systems
- [codegen-doc](https://github.com/linear/linear/tree/master/packages/codegen-doc/README.md) - GraphQL codegen plugin to generate GraphQL fragments and documents
- [codegen-sdk](https://github.com/linear/linear/tree/master/packages/codegen-sdk/README.md) - GraphQL codegen plugin to generate Typescript SDK from fragments and documents
- [codegen-test](https://github.com/linear/linear/tree/master/packages/codegen-test/README.md) - GraphQL codegen plugin to generate a jest test for the Typescript SDK

### Get Started

```shell
# install dependencies
yarn

# build all packages
yarn build

# test all packages
yarn test

# update the schema from the production API
yarn schema

# create changeset for generating CHANGELOG.md
yarn changeset
```

### Plugin Flow

1. The [@linear/codegen-doc](https://github.com/linear/linear/tree/master/packages/codegen-doc/README.md) plugin is used by [codegen.doc.yml](https://github.com/linear/linear/tree/master/packages/sdk/codegen.doc.yml) to generate [fragments and documents](https://github.com/linear/linear/tree/master/packages/sdk/src/_generated_documents.graphql)
2. The [@linear/codegen-sdk](https://github.com/linear/linear/tree/master/packages/codegen-sdk/README.md) plugin is used by [codegen.sdk.yml](https://github.com/linear/linear/tree/master/packages/sdk/codegen.sdk.yml) to generate the typed [Linear SDK](https://github.com/linear/linear/tree/master/packages/sdk/src/_generated_sdk.ts)
3. The [@linear/codegen-test](https://github.com/linear/linear/tree/master/packages/codegen-test/README.md) plugin is used by [codegen.test.yml](https://github.com/linear/linear/tree/master/packages/sdk/codegen.test.yml) to generate a typed [jest test](https://github.com/linear/linear/tree/master/packages/sdk/src/_tests/_generated.test.ts)
