    Test application

    Basic ESLint rules used by Expressen. The test-config (eslint-config-exp/test) is adapted to testing using mocha, mocha-cakes-2 and chai.


    Install eslint and eslint-config-exp:

    npm install --save-dev eslint eslint-config-exp

    Add the following to your .eslintrc.json-file:

      "root": true,
      "extends": ["eslint-config-exp"]

    Add the following to your test/.eslintrc.json-file:

      "extends": ["eslint-config-exp/test"]

    Run with:

    npx eslint .

    Usage in an existing project

    • We advice to remove any husky hooks that uses libraries such as pretty-quick from your package.json
    • Subsequently remove any use of pretty-quick if possible.
    • Remove any previous use of sharable ESLint configs from package.json, i.e.:
      • eslint-config-airbnb
      • eslint-config-google
      • eslint-config-prettier
    • Remove eslint-plugin-prettier from package.json
    • If you get errors similar to the ones below, please update the eslint dependancy.
      • Definition for rule 'no-nonoctal-decimal-escape' was not found
      • Definition for rule 'no-unsafe-optional-chaining' was not found
    • If you still have issues; try updating npm (if you use nvm nvm install-latest-npm) & prettier as-well
    • Remove any 'eslint-disable-line no-unused-expressions' directives added because of chai assertions, they are not needed anymore (eslint-plugin-chai-friendly is used in test).
    • Remove any globals and special rules related to mocha-cakes-2 in your test/.eslintrc.json, they already exist in eslint-config-exp/test.

    Once you complete the steps above run the following:

    npx eslint . --fix

    Usage with Prettier

    If you want to use Prettier, run it before eslint. ESLint should be the final judge, i.e. run:

    npx prettier --save .
    npx eslint . --fix

    This will format the entire code base according to the rules of Prettier and the config.

    Enable format on save
