How to configure ionic with nodejs

Ionic is an open source mobile application development framework based on Angular and Apache Cordova. Due to its open source nature, we can use our favorite programming language for development. It is very necessary to configure Node.js to support our Ionic project, because it can provide us with many useful tools, plug-ins and templates to facilitate our development.

In this article, we will introduce in detail how to use Node.js for configuration in Ionic.

1. Installing Node.js

First, we need to install Node.js on the computer. For specific installation steps, please refer to the Node.js official website.

2. Install NPM

When installing Node.js, npm is usually installed together. But if you do not have npm installed, you can enter the following command on the command line to install it:

npm install -g npm

This will install npm globally.

3. Initialize our Ionic application

Enter the root directory of our Ionic project, open the terminal, and enter the following command:

ionic start myApp blank

Here we create Take the application of a blank template as an example. If you want to create other templates, please choose according to your needs.

4. Install gulp and bower

We need to install gulp and bower to manage our builds and dependencies.

npm install -g gulp bower

This will install gulp and bower globally.

5. Install related dependencies in the Ionic application

In the root directory of the Ionic application, enter the following instructions to install the dependencies we need:

cd myApp
npm install
bower install

This will install all the dependencies of the Ionic application.

6. Configuring gulpfile.js

We need to add the following code to gulpfile.js:

var gulp = require('gulp'),
    bower = require('gulp-bower'),
    concat = require('gulp-concat'),
    uglify = require('gulp-uglify'),
    rename = require('gulp-rename');
 
var paths = {
    sass: ['./scss/**/*.scss'],
    scripts: ['./www/js/*.js']
};
 
gulp.task('default', ['sass', 'scripts'], function(done) {
    gulp.watch(paths.sass, ['sass']);
    gulp.watch(paths.scripts, ['scripts']);
});
 
gulp.task('sass', function(done) {
    gulp.src(paths.sass)
        .pipe(sass())
        .on('error', sass.logError)
        .pipe(gulp.dest('./www/css/'))
        .pipe(minifyCss({
            keepSpecialComments: 0
        }))
        .pipe(rename({
            extname: '.min.css'
        }))
        .pipe(gulp.dest('./www/css/'))
        .on('end', done);
});
 
gulp.task('scripts', function(done) {
    gulp.src(paths.scripts)
        .pipe(concat('app.js'))
        .pipe(gulp.dest('./www/js/'))
        .pipe(rename('app.min.js'))
        .pipe(uglify())
        .pipe(gulp.dest('./www/js/'))
        .on('end', done);
});
 
// install bower packages to www/lib/
gulp.task('bower', function() {
    return bower({});
});

The above code defines some gulp tasks and corresponding rely.

7. Run the build task

In the root directory of our Ionic app, run the following command to run our gulp task:

gulp

This will build Our application generates relevant files. At the same time, gulp's listening task will monitor our code changes and automatically build.

The above is how to configure using Node.js in Ionic. Using Node.js can facilitate our development and also make our projects more maintainable. If you haven't configured with Node.js yet, we highly recommend you give it a try.
