Paste is a design system used to build accessible, consistent, and high quality customer experiences at Twilio. Paste is open source and contributions are welcome.
For usage guidelines, please see our documentation website.
Clone the repo then run the following commands from within the repo's folder:
yarn # bootstraps the repo and downloads packages
yarn build # builds all of Paste
Then you can run a local storybook instance with:
yarn start:storybook
For more commands, please reference the package.json file.
Before contributing, please make sure that you read our Contributing Guidelines and agree with our Code of Conduct.
Each change to a package must come with a changeset. You should have an individual changeset for each package you have touched.
To create a changeset you can run:
yarn changeset
Follow the prompts shown to you in your terminal.
Instructions on how to use the cli tool can be found here, but all you should need to do is generate a changeset and commit it with your Pull Request.
We use Chromatic to host the Storybook instance.
Paste is a monorepo and has some specific requirements in how it handles dependencies.
Each package can have dev dep requirements, such as typescript. As this is a monorepo using yarn workspaces there is no requirement to list these as package dev deps. All dev deps are hoisted to the monorepo root. Declare them at the root package.json file.
A special note about peer deps: Peer dependencies should be hoisted up the dependency tree. If package-a lists package-b as a peer dep, and package-b lists package-c as a peer dep, package-c must also be listed as a peer dep for package-a. All the way down the tree.
A real example might be a Button. Button may only have a peer dependency on Box, but Box has a peer dependency on Theme, Design-Tokens, and Style-Props. These child peer deps need to be hoisted to the Button package. As such Button deps should look like:
{
"name": "button",
"peerDependencies": {
"@twilio-paste/box": "^0.0.1",
"@twilio-paste/theme": "^0.0.1",
"@twilio-paste/design-tokens": "^0.0.1",
"@twilio-paste/style-props": "^0.0.1"
}
}
When a package has a peer dependency on another internal package in the mono repo, it must also be listed as a dev dependency for compilation.
{
"name": "button",
"peerDependencies": {
"react": "^16.8.6",
"react-dom": "^16.8.6"
"@twilio-paste/box": "^0.0.1",
"@twilio-paste/theme": "^0.0.1",
"@twilio-paste/design-tokens": "^0.0.1",
"@twilio-paste/style-props": "^0.0.1"
},
"devDependencies": {
"@twilio-paste/box": "^0.0.1",
"@twilio-paste/theme": "^0.0.1",
"@twilio-paste/design-tokens": "^0.0.1",
"@twilio-paste/style-props": "^0.0.1"
}
}
Releasing Paste happens via CI/CD using Changesets.
