    React Design Toolkit

    The React implementation of Pantheon's Design System


    Coverage Status


    To contribute any changes, updates, or new components to the Design Toolkit please follow the governance guidelines.

    Development setup


    • You must update your NPM config to allow for Font Awesome Pro: Wiki
    • You must also update your NPM config to allow access to the pds-tokens package: Local Development Instructions
    • Install Node.js with the active LTS version. To install the LTS version, you can use NVM (Node Version Manager), N version manager, or any other node manager tool.
      • Option: N
        • Run yarn install -g n
        • Run n lts
      • Option: NVM
        • Run curl -o- | bash to install NVM.
        • Run nvm install --lts.
    1. yarn install will get all the deps down
    2. yarn build will get the toolkit built
    3. yarn storybook will then open a browser tab that shows the completed components in storybook

    Optional setup configuration

    Automatic Node version switching

    • Set up automatic Node version switching on .nvmrc (optional):

      • For nvm as a Version manager, the following might help you:

        • If you happen to be a bash user, you can refer to this script on nvm README.

          • Please note that this will search up for a .nvmrc from your current working dir.
        • If you are more a zsh user, you can use this script on nvm README.

        • If you use fish, there's also a script on nvm README for you.

          • This one requires you to have bass installed.
      • For n as a Version manager, it seems that it already does the switching for you, given that you have a version labeled as auto on n:

        • There is an auto label to read the target version from a file in the current directory, or any parent directory. n looks for in order:

          • .n-node-version: version on single line. Custom to n.
          • .node-version: version on single line. Used by multiple tools: node-version-usage
          • .nvmrc: version on single line. Used by nvm.
          • if no version file found, look for engine in n docs. More specifically, the part after the auto label instructions on Specifying Node Versions.

    Testing commands

    1. yarn test Run tests
    2. yarn test <dir-name or file-name> Run tests on a specific file or directory only
    3. yarn test -u Update snapshots

    Adopted Practices

    General principles for maintaining healthy code. It's important to revisit this by adding to, or changing these as we learn.

    We Must

    • We must include usage guidelines in the "style guide" output

    We Should

    • We should use the id generator from the @reach/auto-id library for any elements where we need to use the id attribute, in order to avoid potential collisions when toolkit components get rendered on the same page. Example usage:
    import { useId } from "@reach/auto-id";
    // Pass in a user-supplied ID that will be used conditionally if provided
    const id = useId(;
    <div class="foo-bar" id={id}>
    • We should trend toward smaller, simpler components that are composed of each other vs. relying more on props to allow for simpler usage of the components in the toolkit.
    • We should not allow styles to be ovewritten by the consumer of the toolkit, but we should provide a clear API that makes it obvious when the consumer is overwriting styles (eg. <BadStyleOverwrite/>) where needed. The exception to this rule is allowing unstyled, or mostly unstlyed, primatives to accept styling (eg. <ButtonBase/>).

    Initial exploration into the API


    Published version

    1. yarn add @pantheon-systems/design-toolkit-react
    2. Install peer dependencies
    3. Import @pantheon-systems/design-toolkit-react/dist/index.css into the entry point of your application. (ex. index.jsx)

    Local version for testing this package locally

    Linking to this package locally via Yarn link will not work because there are known bugs with loading 2 copies of react. We can accomplish this instead via Yalc:

    1. Follow installation instructions to install yalc on your machine.
    2. In the root folder, run yarn build to build your latest changes and then yalc publish --private
    3. Run yalc add @pantheon-systems/design-toolkit-react in the consumer's root folder
    4. If this is the first time the consumer is installing the toolkit, you will have to complete steps 2 and 3 of the installation instructions for the published version
    5. When changes are made locally, you can build them and then run yalc push --private. This will update all instances of the package in your projects that have added it through yalc.
    6. When local testing is complete, run yalc remove @pantheon-systems/design-toolkit-react in the consumer to remove the yalc copy from node_modules.


    npm i @pantheon-systems/design-toolkit-react
