@patterninc/react-ui

React UI

React UI component library for use at Pattern.

Development

There are 2 ways to run this project:

• Run pnpm dev and set a frontend override in the application you are working with (Predict, Shelf, etc) in order to see your updates.
• Run pnpm storybook to see a local instance of our Library in Storybook.

When making updates, it is important to get changes approved by the UX team and front-end team leads. Please utilize Chromatic to demo your updates before getting your PRs raised.

Chromatic Environment Setup

Before running Chromatic, you'll need to generate a .env file with the necessary credentials and tokens. This process fetches secure parameters from AWS Parameter Store.

Prerequisites

Ensure you have AWS CLI access configured by following the instructions in the Pattern Wiki - AWS CLI Access.

NOTES:

• You may need to first install the AWS CLI here before you can continue with the aws configure sso command.
• There is a registration prompt that appears in the setup that is not specified in the wiki, but you can just press return or enter to continue on in the setup.

Steps to Generate Environment Variables

• Authenticate with AWS: Login to AWS through the command line using the development profile:

  aws sso login --profile dev
  

• Generate the .env file: Run the environment setup script to fetch parameters from AWS Parameter Store:

  bash scripts/env.sh --profile dev
  

• Verify setup: The script will create a .env file populated with Chromatic token mappings from the AWS development account parameter store.

• Run Chromatic: You can now run Chromatic as usual within your application:

  pnpm chromatic
  

Note: The .env file contains sensitive information and should never be committed to version control. It's already included in .gitignore for security.

Adding/Updating Types

Typescript typechecking happens at build-time, so setting a frontend override won't help with typechecking. To ensure your types still work, you'll need to:

• yalc publish in this repo

• yalc link @patterninc/react-ui in the repo where the code will be tested (shelf/predict/marketshare/etc.)

After that, you can easily push out updates/changes from here (react-ui) to the other repos by doing:

• yalc push --scripts

Note: you can either install yalc globally, or prefix all the previous commands with npx, e.g. npx yalc publish

Updating package.json version

Do either of the following:

• Run npm version patch
• Manually update the package.json version field by opening package.json and incrementing the last number

Removing yalc from Apps

Once you've tested the types, run

• yalc remove @patterninc/react-ui

in the repo where this code was tested (Predict/Shelf/Marketshare/etc) to remove yalc changes

Workflow for Publishing NPM Versions and Bumping Related Repositories Versions

npm-publish.yml Github workflow automates the process of publishing a new version of a react-ui package to NPM and bumping the version in another repository. The workflow will run whenever a new commit is pushed to a master branch in react-ui Git repository. It automatically updates the versions of the following repositories.

• predict
• shelf-ui
• marketshare-ui
• toggle
• admin
• connect

The steps below describe how to bump the version of a newly added react repository.

Step 1: Add Github Actions Workflow to new repository.

Copy the workflow file from the admin repository and replace the repo name with the new repo name from the workflow file and push to master/main branch of repository

Step 2: Modify the npm-publish.yml Workflow to include the new repository version upgrade.

Inside the npm-publish.yml workflow, add a new job before "notify-slack-on-failure"

<new-repo-name>-upgrade-package:
  needs: [publish]
  runs-on: ubuntu-latest
  name: <new-repo-name>-upgrade-package
  if: needs.publish.outputs.publish_type != 'none'
  steps:
    - name: Execute <new-repo-name> GHA workflow to upgrade react-ui package with latest version
      uses: convictional/trigger-workflow-and-wait@v1.3.0
      with:
        owner: patterninc
        repo: <new-repo-name>
        github_token: ${{ secrets.GHA_RUNNER_TOKEN }}
        workflow_file_name: react-ui-package-upgrade.yml
        ref: main

We can enable react-ui version bumping for new repositories by making the changes listed above.
