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. You only need to make a PR with the changes. There is no need to bump the version in package.json file in your PR. A github action will automatically bump the version and publish the package to npm after PR is merged.

After you have submitted a PR,

1. Get the full commitID of the last commit in your PR, and run npm install git+https://github.com/Expensify/eslint-config-expensify.git#COMMIT_ID in the repo against which you want to test those changes.
2. This should update the resolved path of eslint-config-expensify in package-lock.json file, and ensures the repo is referencing to the correct local version of the eslint config.
3. Now, you can run npm run lint or perform any other tests you want in that repo.

1. A GitHub action will automatically bump the version and publish the package to npm after PR is merged.
1. Go into the App, Web-Expensify and Web-Secure repos and run npm install eslint-config-expensify@latest -E. 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
