EOX ESLint & Prettier config vor Vue

Installation

npm install --save-dev EOX-A/code-style-vue
or
npm install --save-dev https://[e-mail]/EOX-A/code-style-vue.git

Usage

Prettier

To run prettier and format all your files in the current folder, use

npx prettier --write .
or
npx prettier --write "**/*"

Please refer to the Prettier CLI docs for further details.

ESLint

To include ESLint in the project, create a file called .eslintrc.js in the app root:

module.exports = {
  extends: ['@eox/code-style-vue']
}

Finally, to run ESLint with auto-fixing, use

npx eslint . --fix

Please refer to the ESLint CLI docs for further details.

Ignoring files

You can add .eslintignore and .prettierignore files to ignore certain folders or files/patterns.

Both ignore files should ideally have the same content, e.g.:

public
dist
*.min.js
*.bundle.js

# adapt according to your project needs

Custom configuration & rules

Both Prettier and ESLint allow for some rule customization. Please check the Prettier configuration options and the ESLint rules for an explanation of rules that could be added/modified to this file for individual projects.

BUT: please consider if this is really necessary, or if it could be included in the centralized config rather than in an individual project. Ideally, the individual projects should not use any custom rules.

Checking for valid code

To check if your code is valid before committing or inside a CI pipeline, use

npx prettier --check .
npx eslint .

Automation in VS Code (extension, settings)

Prettier

Although you can use prettier via command line, in a pre-commit hook or in a CI pipeline, you can also use the VS Code extension to format files (or file sections) via a handy command or even automatically (e.g. on file save) right inside your code editor.

--> Prettier - Code formatter extension

Please refer to the description about setting up and using the extension!

As a bare minimum, create a .prettierrc.json file in the app root to let the editor know prettier is used in this project

echo {} > .prettierrc.json

ESLint

As for ESLint, automatically running and fixing your code can be obtained by changing the settings in your workspace or dev container settings, e.g.:

"editor.codeActionsOnSave": {
  "source.fixAll.eslint": true
},
