snaps-monorepo

Monorepo for experimental snaps dependencies.

Contributing

Installing

Run yarn install in the project root directory. Do not run any installation commands in individual workspaces.

If you add a dependency with a lifecycle script, said dependency must be added to the devDependencies and lavamoat.allow-scripts config of the root package.json file. This is currently the only way to use @lavamoat/allow-scripts in monorepos.

Building

Run yarn build to build all packages in correct order. If you encounter any errors, try yarn build:clean, and if that fails, check the TypeScript configuration (see below).

You can also run yarn build in a specific package / workspace, although you have to ensure that its dependencies have been built.

Repository-wide watching is currently not possible due to the build processes of some packages.

Configuring TypeScript

The TypeScript configuration of this monorepo is brittle, and requires manual maintenance. It uses TypeScript project references and composite sub-projects (i.e. monorepo package). In short, the root tsconfig.json must contain an empty files array, and references to each interdependent project with a tsconfig.json in its root directory. Meanwhile, every sub-project must explicitly declare the relative paths to its local dependencies via its references array.

If building from the monorepo root suddenly starts to fail, check if the errors are referring to monorepo packages, and verify that their tsconfig.json files are configured correctly.

Some packages do not require a tsconfig.json file. These packages must be explicitly ignored in the TypeScript config lint script. If a package is neither referenced nor ignored, linting will fail.

Testing and Linting

Run yarn test and yarn lint in the project root directory, or in a workspace.

Publishing

  1. Run Create Release Pull Request workflow
  2. Checkout the created branch.
  3. Update CHANGELOG.md in each package, moving changes to their categories and make them more descriptive.
  4. Run yarn install in root to update yarn.lock.
  5. Run yarn build in packages/examples to update snap manifests
  6. Get the PR merged, Publish Release workflow will start on main branch.
  7. After the workflow does a dry run, manually approve the deployment in Github Actions tab.

To publish locally from the monorepo root use:

yarn publish:all --otp=YOUR_NPM_OTP_CODE
