Javascript Question

how to do linting using nodemon?

Can I use nodemon to lint my javascript? I am not using any build tool e.g. gulp or grunt and want to maximize the use of node and npm.

The output from nodemon can be piped. I want to use this for linting the changed file using eslint.

Here is my package.json



{
"name": "app",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "nodemon server.js",
"lint": "eslint"
},
"dependencies": {
"MD5": "*",
"clean-css": "*",
"express": "~4.9.0",
"express-handlebars": "~2.0.1",
"express-redis-cache": "*",
"foundation-sites": "~5.5.3",
"fs-extra": "~0.8.1",
"node-rest-client": "~1.5.1",
"node-sass": "*",
"path": "*"
},
"devDependencies": {
"babel-eslint": "^4.1.6",
"eslint": "^1.10.3",
"eslint-config-airbnb": "^2.1.1",
"eslint-config-airbnb-es5": "^1.0.8",
"eslint-plugin-react": "^3.13.1",
"nodemon": "~1.8.1",
"parallelshell": "~2.0.0",
"watch": "~0.17.1"
}
}





I tried this. But it doesn't work.It gives error.

"scripts": {
"start": "nodemon({ script: 'server.js' }).on('restart', function () {console.log('nodemon started');}).on('crash', function () {console.log('script crashed for some reason');});",
"lint": "eslint"
},

Answer

You can use the exec option of nodemon to run your tests as you save code. Here's an example:

nodemon server.js --exec 'npm run test && node'

This will cause nodemon to run npm run test && node server.js, and it won't start the server until all the tests have run successfully.
