ESLint Changes

ESLint changes is a script that is run by TravisCI for commits and pull requests. It runs ESLint on the files that were changed and adds the results to GitHub as a status.

Installation

• Set GITHUB_TOKEN environment variable in Travis to be a GitHub access token with repo privileges.
• Install the eslint-changes package from npm during the Travis install step:

install:
  - npm install eslint-changes

• Run the ESLint Changes bin during the Travis script step:

script:
  - ./node_modules/.bin/eslint-changes

Details

• ESLint Changes has eslint: "3.x" as a peer dependency. That means that your project must already have eslint installed and configured.
• ESLint Changes will use any configuration like .eslintrc, .eslintignore, plugins or other configurations that are present in the project.
• If you don't like installing eslint-changes from Travis, you can add it to your project's package.json and add only the script part to .travis.yml. Just be sure to run npm install --save-dev eslint-changes.
