Development notes

Generate types

@kinvolk/headlamp-plugin ships type declarations from the frontend module. To generate the declarations, run npm run build.

How to test local changes to headlamp-plugin

Developing headlamp-plugin itself? Want to test your changes?

Integration tests

See test-headlamp-plugin.js for some basic integration tests.

See test-headlamp-plugin-published.js for testing published packages.

linking to use local version of headlamp-plugin

Use your changes inside a plugin with an npm feature called linking:

1. Run npm link within the src/plugins/headlamp-plugins folder.
2. Create the plugin with link: npx --yes @kinvolk/headlamp-plugin create myplugin --link
3. Develop your plugin using your local headlamp-plugin changes.

This internally does a npm link @kinvolk/headlamp-plugin, so the development version is linked rather than using a released version from npm.

Why is this needed? Whilst npx uses linked packages by default, npm install requires that you first use npm link packageName. See the npm link docs for more info on npm link.

Testing "headlamp-plugin create" changes

For the "create" command npx and linking doesn't work. Instead, for this one command, you can call the script directly.

cd plugins/headlamp-plugin
node ./bin/headlamp-plugin.js create myplugin --link

Keep the dependencies in sync with the frontend/

Run npm run update-dependencies so the packages are kept up to date with there.

A lot of the packages are shared between the two, but some are not. See dependencies-sync.js for lists of dependencies which are shared/not-shared. You may need to update these lists when adding/removing packages.

Run npm run check-dependencies to see if frontend/package.json and headlamp-plugin/package.json are synced. This is run in CI to make sure when dependencies are changed, they are synced appropriately.

Upgrading to an alpha release

You can try an alpha release for testing with the following command.

npx @kinvolk/headlamp-plugin@alpha upgrade --headlamp-plugin-version=alpha your-plugin-folder

Making an alpha release of headlamp-plugin

You can bump the version to do a new alpha release like so:

cd plugins/headlamp-plugin
npm version preminor --preid=alpha
v0.6.0-alpha.0

Then to do another prerelease do...

npm version prerelease --preid=alpha
v0.6.0-alpha.1

To set the "alpha" tag when publishing do the following.

npm run build && npm pack
npm publish kinvolk-headlamp-plugin-0.6.0-alpha.0.tgz --tag alpha

If you don't specify a tag, npm publish uses the "latest" tag.
