## README

# eslint-config-madgex

[ESLint](https://eslint.org) rules related to Madgex projects.

## Install

```bash
npm install eslint@10 @madgex/eslint-config-madgex -save-dev
```

## VSCode extension

Use the official VSCode [ESLint Extension](https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint) v 3.0.21+

## Usage

> ⚠️ Recomended to use only 1 type of source file in your repo, either `commonjs` or `module` (esm). `eslint` & `eslint-plugin-n` (this config depends on) has difficulty supporting both at the same time in a monorepo.

`eslint-plugin-n` which is a part of our config, reads the package.json for node version, and what `type` of JS files you use (ESM or commonjs).

```json5
// package.json
{
  ...
  "type": "module", // "module" (ESM), or "commonjs" - you cant use both
  {
    "engines": {
      "node": ">=24"
    }
  },
  ...
}
```

`eslint-plugin-n` also recognises `.npmignore` files which will silence warnings of missing dependancies when they are installed as `devDependancies`.

### Node/Browser

```js
// eslint.config.js
import configMadgex from '@madgex/eslint-config-madgex';

export default [...configMadgex];
```

### Vue

config order matters.

```js
// eslint.config.js
import configMadgex from '@madgex/eslint-config-madgex';
import pluginVue from 'eslint-plugin-vue';
// pluginVue.configs['flat/recommended'] has prettier conflicts

export default [...configMadgex, ...pluginVue.configs['flat/essential']];
```

### Rules

Notes regarding specific rules enforced in this config:

- [`no-param-reassign`](https://eslint.org/docs/latest/rules/no-param-reassign) - Disallow reassigning function parameters, except for **`accu`** which is the accumulator in a `.reduce()` e.g.

  ```js
  Array.reduce((accu, key) => {
    accu[key] = getVal(key);

    return accu;
  }, {});
  ```

- [`no-unused-vars`](https://eslint.org/docs/latest/rules/no-unused-vars) - Disallow unused variables, except for `request` and `h` as found on hapi.js route handlers.
