How do I set up linting in CircleCI?

To set up linting in CircleCI, you'll need to add a linting step in your configuration file. What language are you using?

I'm using JavaScript with ESLint.

Great! You can add a step in your .circleci/config.yml like this:

version: 2.1
jobs:
  lint:
    docker:
      - image: circleci/node:latest
    steps:
      - checkout
      - run:
          name: Install ESLint
          command: npm install eslint
      - run:
          name: Run ESLint
          command: npx eslint .

This will install ESLint and run it on your codebase.

Do I need to configure ESLint before running it?

Yes, you should have an .eslintrc configuration file in your project to define your linting rules. You can create one using npx eslint --init.
