# yeslint!
2023-07-27 22:22:36 +02:00
A sensible, modern collection of configuration files for [ESLint] that enforces beautiful and correct code. It contains both rules to ensure correct code (e.g. enforce `break` statements in each `switch` `case`), and rules to make your code beautiful (e.g. adding a trailing comma to array items that start on a newline).
2023-07-27 21:56:03 +02:00
## What's included
Currently, the 3 following configuration files are available:
* `generic`: generic ESLint configuration for all modern JavaScript runtimes.
* `node`: an extension on the generic config, with rules specific to Node.js.
* `svelte`: configuration for [Svelte] and JavaScript in browser environments.
## Examples
Please see [the `examples` directory](./examples) for some examples. Files that start with `wrong.` contain many errors, and the fixed version of those files is in their `correct.` equivalent.
## Installation
Install it together with ESLint using [npm], [pnpm], [Yarn], or whatever package manager you like to use:
```bash
npm install --save-dev eslint @garraflavatra/yeslint
2023-07-27 21:56:03 +02:00
```
```bash
yarn add --dev eslint @garraflavatra/yeslint
2023-07-27 21:56:03 +02:00
```
```bash
pnpm add --save-dev eslint @garraflavatra/yeslint
2023-07-27 21:56:03 +02:00
```
Then, tell ESLint to extend this configuration. Add it either in `.eslintrc.json`, add it as the default export in `.eslintrc.js`, or add it in your `package.json` under the `"eslintConfig"` key.
Please consider the following example. You should replace `<name>` with the name of the configuration you want to use.
```javascript
module.exports = {
2023-07-28 20:33:10 +02:00
extends: './node_modules/@garraflavatra/yeslint/configs/<name>.js',
2023-07-27 21:56:03 +02:00
};
```
Or add this to your `package.json` file:
```json
"eslintConfig": {
2023-07-28 20:33:10 +02:00
"extends": "./node_modules/@garraflavatra/yeslint/configs/<name>.js"
2023-07-27 21:56:03 +02:00
}
```
After installing, run `npx eslint .` to lint your code for the first time, or use `npx eslint --fix .` to lint while automatically fixing all auto-fixable problems ESLint finds in your codebase.
