Today we will take a quick look at how to configure VS Code to automatically format your code according to your ESLint rules every time you save a file.
This assumes that you already have some ESLint rules in place. If not the airbnb rules are a good place to get you started.
Once you have rules setup and are hacking away in VS Code, the editor will start to complain every time you forget that "you should indent x" or whatever extraordinary rule your company might use. Especially if you are regularly engaged with different companies using different styles this becomes quite cumbersome. Luckily there are two plugins that can help us get around this.
With prettier you can achieve great things, even format your code on commit which can greatly help to streamline coding-style across the team. For today we will only use it every time we save a file in our editor. To achieve this we simply add two lines to our settings.json.
"editor.formatOnSave": true, "prettier.eslintIntegration": true
You can find your settings.json by using
Preferences: Open User Settings from your Command Palette (⇧+⌘+P | ⇧+CTRL+P).
And now every time you save a file Prettier will format it according to your ES Lint configuration.
