Setting up Node.js Development to avoid manual server restart

In my previous post, I have shared how we can make the startup page for Node.js. Now every time we change anything to the server we need to go to command prompt and rerun the command. Instead we can make something which will keep watching changes in specific types of file and restart the server as necessary. This is a big timesaver for Node.js development.

We can achieve this by leveraging gulp and nodemon package.

So first install gulp

$ npm install gulp

Then install nodemon

$ npm install gulp-nodemon

Then add a file to the project’s root folder named gulpfile.js and add below code

var gulp = require(‘gulp’);

var nodemon = require(‘gulp-nodemon’); //notice we are using gulp-nodemon

var jsFiles = [‘*.js’, ‘src/**/*.js’]; //This watches the types of file with their location

gulp.task(‘alwaysonserver’, [], function () {

var options = {

script: ‘app.js’,

delayTime: 1,

env: {

‘PORT’: 5000

},

watch: jsFiles

};

return nodemon(options)

.on(‘restart’, function (ev) {

console.log(‘Restarting…..’);

});

});

Now we need to run

$ gulpfile alwaysonserver

And make changes to any js file you will get the below output and don’t need to rerun the comman

Namoskar!!!
