you don’t need to extend any existing ESLint libraries (like I did with airbnb and React) and you can enforce whichever rules you’d like.<h2>Step 2:  [ICODE].eslintrc.js[/ICODE]</h2>If you want to run linting from the command line at any time (in the case of CI or a post-commit hook, for example), you will need to create a [ICODE].eslintrc.js[/ICODE] file to kick off the linting:const Neutrino = require('neutrino');const pkg = require('./package.json');const api = new Neutrino(pkg.config.presets);module.exports = api.custom.eslintrc();[ICODE].eslintrc.js[/ICODE] creates a Neutrino instance with presets defined in [ICODE]package.json[/ICODE] (we’ll get to that in the next section) and exposes a [ICODE]eslintrc()[/ICODE] function that runs the lint routine.<h2>Step 3:  Modify [ICODE]package.json[/ICODE]</h2>With the preset created with your custom linting rules in mind, a few changes to [ICODE]package.json[/ICODE] must be made.  The first is adding this custom preset file to the [ICODE]config.presets[/ICODE] array:"config": {  "presets": [    "neutrino-preset-react",    "conduit-preset.js"  ]},Next we’ll need to add Neutrino’s airbnb preset to our dependency list:yarn add neutrino-preset-airbnb-base -devLastly we’ll add a [ICODE]lint[/ICODE] key to [ICODE]scripts[/ICODE] so that we can run linting from command line:"scripts": {  "lint": "./node_modules/eslint/bin/eslint.js --ext .js,.jsx src/ test/",}Now we can run the following from command line:yarn lintAlso note that the custom linting rule are applied to both the manual [ICODE]lint[/ICODE] command as well as during webpack’s live reload and linting routine!I love Neutrino because it requires minimal configuration to get up and running but custom configuration is easy when you need to.  Keep an eye on Neutrino moving forward because development is shipping quickly and the community is rallying behind this amazing project!The post <a href="https://davidwalsh.name/neutrino-linting" target="_blank">Custom Neutrino Linting</a> appeared first on <a href="https://davidwalsh.name" target="_blank">David Walsh Blog</a>.<a href="https://tkjs.us/dwb" target="_blank"><img src="https://davidwalsh.name/demo/tjs_block-1.svg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a><a href="https://davidwalsh.name/neutrino-linting" target="_blank">Continue reading...</a></blockquote>
