Common Gocomo eslint settings. Inspired by eslint-config-wesbos

• Lints JavaScript based on the latest standards incl. Sonar-Rules
• Fixes issues and formatting errors with Prettier
• You can see all the rules here.

1. If you don't already have a package.json file, create one with npm init.

2. Then we need to install everything needed by the config:

npx install-peerdeps --dev @gocomo/eslint-config-gocomo

3. You can see in your package.json there are now a big list of devDependencies.

4. Create a .eslintrc file in the root of your project's directory (it should live where package.json does). Your .eslintrc file should look like this:

{
  "extends": ["gocomo"]
}

Once you have done the above install, you probably want your editor to lint and fix for you. Here are the instructions for VS Code:

1. Install the ESLint package
2. Install the Prettier package
3. Now we need to setup some VS Code settings via Code/File → Preferences → Settings. It's easier to enter these settings while editing the settings.json file, so click the {} icon in the top right corner:

  "editor.formatOnSave": true,
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "eslint.validate": [ "javascript", "javascriptreact", "typescript" ]
