Workspaces

This monorepo uses yarn workspaces to manage dependencies for all packages.

Adding new packages

Run this command from the monorepo root:

yarn workspace <workspace-npm-package> add --dev <npm-package>

e.g. yarn workspace @hashicorp/design-system-components add --dev ember-cli-flash

Using ember install in the monorepo

Run this command from the monorepo root:

yarn workspace <workspace-npm-package> run ember install <npm-package>

e.g. yarn workspace @hashicorp/design-system-components run ember install ember-a11y-refocus

Changesets

This project uses changesets to manage how changes will be released. Each user-facing change to a package should come with a changeset for each package that has changed.

To create a changeset, run and follow the prompts in your terminal:

yarn changeset

See the changeset docs for more information.

Note: If you want to ignore a changeset bump in terminal (e.g. major bump for selected "package x" is N/A, want a patch release), press return on the command line to skip that step. Press the spacebar to select that step.

Releasing

Release PRs are created and automatically updated on every PR merge by the changeset GitHub action. Once we are ready to do a release, the PR – titled Version Packages – can be approved and merged to main, and the changes will be released to npm automatically.

Local testing of versioning

You can simulate the versioning experience locally with this command:

yarn changeset version

For this step to complete successfully you'll need to keep in mind the following:

First, create a personal access token in GitHub. The name could be anything e.g. design-system, with read:user and repo:status scopes, and then add the token to a .env file in the project's root.

GITHUB_TOKEN=YOUR-TOKEN-HERE

Second, because this command relies on reading information about the change from GitHub, it only works if the changeset files already exist in PRs there. The best option for this is to target an existing PR branch (with a changeset) and run the command against that branch locally.
