@anmiles/eslint-config

Base eslint config for all projects

Presets

Preset	Extends path
Base	./node_modules/@anmiles/eslint-config/src/base.preset.js
TS	./node_modules/@anmiles/eslint-config/src/ts.preset.js
React	./node_modules/@anmiles/eslint-config/src/react.preset.js
Jest	./node_modules/@anmiles/eslint-config/src/jest.preset.js

For JS-only projects (without TS, Jest, React) use base preset. For more complex projects use combination of presets. Note that base preset is mandatory in all cases.

Usage

1. Install this package
   • npm install --save-dev @anmiles/eslint-config
2. Install required devDependencies
   • Base dependencies for all files:
     • npm install --save-dev eslint eslint-plugin-align-assignments eslint-plugin-import eslint-plugin-jsonc eslint-plugin-n eslint-plugin-promise @stylistic/eslint-plugin
   • Additional dependencies for TS:
     • npm install --save-dev @typescript-eslint/eslint-plugin @typescript-eslint/parser eslint-import-resolver-typescript
   • Additional dependencies for React:
     • npm install --save-dev eslint-plugin-react-hooks eslint-plugin-react-redux eslint-plugin-react-refresh
   • Additional dependencies for Jest:
     • npm install --save-dev eslint-plugin-jest
3. Extend all needed presets
   • For JS-only projects (without TS, React, Jest) use base preset:

      extends : [
      	'./node_modules/@anmiles/eslint-config/src/base.preset.js',
      ],

   • For more complex projects use combination of presets
     • Backend TS project with Jest:

        extends : [
        	'./node_modules/@anmiles/eslint-config/src/base.preset.js',
        	'./node_modules/@anmiles/eslint-config/src/ts.preset.js',
        	'./node_modules/@anmiles/eslint-config/src/jest.preset.js',
        ],

     • Frontend TS project with React and Jest:

        extends : [
        	'./node_modules/@anmiles/eslint-config/src/base.preset.js',
        	'./node_modules/@anmiles/eslint-config/src/ts.preset.js',
        	'./node_modules/@anmiles/eslint-config/src/jest.preset.js',
        	'./node_modules/@anmiles/eslint-config/src/react.preset.js',
        ],

4. Specify npm command
   • --ext parameter is redundant. According to documentation, default value is .js and the files that match the specified overrides entries. This is the way this config is being built: it targets specific extensions by using overrides entries and specifying particular extensions in files parameter. Therefore just including all needed presets in .eslintrc will make ESLint automatically cover all needed extensions.

Example

package.json:

	"scripts": {
		"lint": "eslint ."
	}

.eslintrc.js (with using base preset):

module.exports = {
	root    : true,
	extends : [
		'./node_modules/@anmiles/eslint-config/src/base.preset.js',
	],
};

.eslintignore:

someFile.js
/rootDir/anotherFile.js
**/someDir/

Notes

• package-lock.json doesn't have to be ignored. It's already ignored in configuration for jsonp plugin inside base preset.
• node_modules doesn't have to be ignored. It's implicitly ignored by ESLint.
