eslint-config-expensify

This package provides Expensify's .eslintrc as an extensible shared config. Most of our rules are based on Airbnb's style guide.

How to Develop

1. Make a change
2. Bump the version in package.json and submit your PR

After PR is merged

You need to publish the newest version of this to NPM so that we can update it in the other repos

1. From the command line, in the directory for this repo:
2. Run npm login
3. Enter username: 'expensify'
4. Enter password: this is in 1Password for npmjs.com
5. Enter the email: infra@expensify.com
6. Ask for the 2FA code in #infra (feel free to ping @ring0 if you don't get a timely response)
7. Run npm publish
8. Go into the App, Web-Expensify and Web-Secure repos and run npm install eslint-config-expensify@latest. This should update the package.json and package-lock.json file and you can submit a PR with those changes.

Note as of now we have no way of testing these PRs without a separate App, Web or Web Secure PR

Usage

We export two ESLint configurations for your usage.

eslint-config-expensify

Our default export contains all of our ESLint rules, including ECMAScript 6+ and React. It requires eslint, eslint-plugin-import, eslint-plugin-react, and eslint-plugin-jsx-a11y.

Just add extends: 'expensify' to the .eslintrc file in the root directory of your project.

eslint-config-expensify/legacy

Just add extends: 'expensify/legacy' to the .eslintrc file in the root directory of your project.
