Meta

• State: production
• Demo: https://artsy.github.io/reaction
• CI:
• NPM:
• Coverage:
• Point People: @damassi

Installation

$ git clone --recursive https://github.com/artsy/reaction.git
$ cd reaction
$ npm install -g yarn
$ yarn install
$ brew install watchman (If you don't already have Homebrew, go here for installation instructions: https://brew.sh/)
$ cp .env.oss .env

Instructions

• Development of components happen in storybooks:

    $ yarn start
    $ open http://localhost:9001/
  

• Run the tests:

    $ yarn test
  

• Run the tests continuously (or use vscode-jest):

    $ yarn test -- --watch
  

• In vscode, run the TypeScript: Run type-checker task and open the PROBLEMS view to see continuous type-checker results.

• After updating components, be sure to deploy a new demo (sharing is caring!):

    $ yarn deploy-storybook
  

• When using new changes in metaphysics’ schema, be sure to update the local schema copy:

    $ yarn sync-schema
  

• There are some suggested VSCode extensions in .vscode/extensions.json and additional docs at docs/vscode.md.

Developing in Force

Before you start, you should ensure Force is on the right branch and up-to-date.

Use yarn to kick off the force development process.

yarn integrate force

This command will build and compile reaction, publish it locally so it can be used in other places, link it into force for you, and then start reaction and force in watch mode.

This assumes force is a sibling directory of reaction. If it's not you can use the following setup instead.

PROJECT_PATH=path/to/force yarn integrate

If you need to attach force to a debugger, use the ENABLE_DEBUGGER command as follows

ENABLE_DEBUGGER=true yarn integrate force

Manual Linking and Unlinking with Force

To link your local reaction with your local force, run:

    $ yarn link && yarn watch
    (wait until you see a message that X files have been successfully compiled before moving on)

    $ cd ../force && yarn link @artsy/reaction && yarn start

To unlink your local reaction from your local force, run (in Force):

    $ yarn unlink @artsy/reaction
    $ yarn add @artsy/reaction
    $ yarn start

Deployments

Reaction uses auto-release to automatically release on every PR. Every PR should have a label that matches one of the following

• Version: Trivial
• Version: Patch
• Version: Minor
• Version: Major

Peril will automatically add "Version: Patch", if you don't set one on creating your PR. No release will happen on a Trivial update.

If you're making a change but you don't want to immediate trigger a release (i.e. when 2 PRs need to go out together), specify the correct version and add the Skip Release label. That'll ensure when the next release happens the version is still bumped appropriately.
