module.exports = {

crafty jsLint

This linter will leverage ESLint to lint your JavaScript files with the Swissquote presets pre-configured. All ESLint CLI options are valid here.

The additions made by this command are:

  • Pre-configured rules, defined by eslint-plugin-swissquote activated using --preset.
  • Uses babel-eslint as a parser to support new syntax that ESLint doesn't understand yet.

there are 4 presets available for you :

  • format Base formatting rules, should work on any code (included in legacy and recommended)
  • node Adds environment information for Node.js
  • legacy For all your EcmaScript 5 code
  • recommended For al your EcmaScript 2015+ code, also contains rules for React

Setting presets is done with the --preset option

The order of the presets is important as some rules might override previous ones.

For example:

crafty jsLint src/** --preset format --preset node --preset recommended

If no preset is specified recommended is used.

If you pass the --fix flag it will fix all the errors it can and write them directly to the file.
