Installation

Quick start

Documentation

• Ultraviolet UI

• Ultraviolet Plus

• Ultraviolet Form

• Ultraviolet Themes

• Ultraviolet Icons

Development

Before any command, install dependencies running following command:

$ pnpm install

Storybook

Our storybook includes @ultraviolet/ui, @ultraviolet/form and @ultraviolet/icons.

In order to start storybook without errors you will need to build the project once (this is because @ultraviolet/form uses @ultraviolet/ui build to run).

$ pnpm build
$ pnpm run start

Storybook documentation will then be available on http://localhost:6006

Test

Unit

$ pnpm run test:unit # Will run all tests
$ pnpm run test:unit:update # Will update all snapshots
$ pnpm run test:unit:watch # Will watch tests and only rerun the one who are modified
$ pnpm run test:unit:coverage # Will generate a coverage report
$ pnpm run testunit::coverage --coverageReporters lcov && open coverage/lcov-report/index.html # Will generate an open an html code coverage report

Accessibility

$ pnpm run test:a11y # Will run all accessibility tests
$ pnpm run test:a11y src/components/Alert # Will run accessibility test of Alert component only

Lint

$ pnpm run lint
$ pnpm run lint:fix

Typecheck

Running npx typecheck --noEmit won't work at root of the project. To run type check for all packages you need to run the following command:

$ pnpm run typecheck # this is a package json script that will run typecheck for all packages recursively

If you still want to use npx, you can run it from a package folder:

$ cd packages/ui
$ npx typecheck --noEmit

Build

$ pnpm run build
$ pnpm run build:profile # Will open a visual representation of the modules inside the compile package

Use a locally built package

You might want to test your local changes against a React application.

yalc is a tool aiming to simplify working with local npm packages by providing a different workflow than npm/pnpm link, hence avoiding most of their issues with module resolving.

$ pnpm install --global yalc # Make sure to have the yalc binary

Here is an example for using @ultraviolet/ui as a local package:

$ pnpm run build && cd packages/ui && yalc publish
$ # Now it's ready to install in your project
$ cd ../project-something
$ yalc add @ultraviolet/ui
$ cd ../ultraviolet
$ # If you do some changes into your package
$ pnpm run build && yalc publish --push --sig # --push will automatically update the package on projects where it have been added, --sig updates the signature hash to trigger webpack update

You can redo the same with @ultraviolet/form if you want to test it.

:warning: since 1.0.0.pre.51 (2021-04-23), yalc publish needs the --sig option to trigger webpack module actual update.

:warning: yalc create a yalc.lock and updates the package.json in the target project. Make sure to not commit these changes

Versioning

We are using Changeset to manage our versioning.

Once your modifications are ready to be released, you can run pnpm run changeset to create a new changeset. It will ask you to describe your changes and will create a new changeset file in the changesets folder.
