How to use Node.js with Eclipse IDE [Step-by-Step]

This tutorial teaches you how to use Node.js with Eclipse IDE using the nodeclipse package. We install Node.js and the Eclipse IDE on Ubuntu before using Node.js with the IDE. You can jump to section 3 if you have already installed Node.js (section 1) and Eclipse IDE (section 2) on your system.

 

Section-1: Installing Node.js

Check if Node.js is installed

Knowing how to use Node.js with Eclipse IDE starts by installing Node.js and Eclipse IDE. First, check for a Node.js installation.

# Check the binaries
$ which node
$ which npm

# or their versions
$ node -v
$ npm -v

Output

user@hostname:~$ which node
user@hostname:~$ which npm
user@hostname:~$ node -v
Command 'node' not found, but can be installed with:

user@hostname:~$ npm -v
Command 'npm' not found, but can be installed with:

Node.js is not installed on the system. We can install the latest version as follows.

 

Install Node.js from the source

We have already covered this topic in detail in Install Node.js on Ubuntu 20.04 [3 Different Methods] so we will keep this section short and to the topic:

Update, then upgrade the system.

$ sudo apt update
$ sudo apt upgrade

Install the curl tool before downloading Node.js version 18+ from the sources.

# install curl
sudo apt install curl

# download the files from Node.js sources to Ubuntu repositories
curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -

Then, install the downloaded files.

sudo apt-get install -y nodejs

Now let's confirm the installations.

Input

$ node -v
$ npm -v

Output

user@hostname:~$ node -v
v18.10.0
user@hostname:~$ npm -v
8.19.2

Node.js version 18.10.0 is now installed on the system.

Section-2: Installing Eclipse

Eclipse IDE requires Java installation before being installed on the local machine. Let's update the system and then install Java Development Kit.

 

Install Java

We have covered detailed guide on installing Java on Liux, Windows and MAC Platform. So, we will keep this section short by just giving brief command outputs:

$ sudo apt update
$ sudo apt install default-jre

Check the installed JDK version.

Input

$ java --version

Output

user@hostname:~$ java --version
openjdk 11.0.16 2022-07-19
OpenJDK Runtime Environment (build 11.0.16+8-post-Ubuntu-0ubuntu122.04)
OpenJDK 64-Bit Server VM (build 11.0.16+8-post-Ubuntu-0ubuntu122.04, mixed mode, sharing)

Section-3: How to use Node.js with Eclipse IDE by developing an Express Web Server

This section teaches you how to use Node.js with Eclipse IDE by loading a styled HTML page using a web server built with the express framework.

 

Set up a lab environment

Here is the project structure.

Create the structure before initializing an NPM package and installing express.

eclipseNode
├── index.js
└── public
    ├── index.html
    └── style.css

1 directory, 3 files

I create the project structure as follows.

$ mkdir eclipseNode && cd eclipseNode
$ mkdir public
$ touch public/index.html public/style.css
$ touch index.js
$ npm init -y
$ npm i express

Import the project in Eclipse

Install nodeclipse package with NPM.

$ sudo npm install -g nodeclipse

The package enables us to use a CLI with NPM, install third-party packages, and run multiple utility commands.

Input

$ nodeclipse

Output

Advertisement
user@hostname:~/projectDir$ nodeclipse 
  Usage: nodeclipse [arguments] 
  `nodeclipse --help install` for Nodeclipse CLI Installer Help

Arguments: 
-c, --create <name>      create project folder and prepare it 
-u, --use <template>     use/copy specified template when creating project 
-p, --prepare            prepare Nodeclipse [Node.js] project for import, i.e. add needed `.project` file and other `.*`
                      files ('.gitignore', '.jshintrc', '.settings/') if there is no `.project` yet
-g, --eclipse_project_general   prepare General Eclipse project for import, i.e. add only needed `.project` file
-n, --name [<name>]      project name (default is folder name)
-h, --help               this help screen
-v, --version            print nodeclipse CLI's version
-V, --verbose            be verbose

Templates are just folders in this project sources:
hello-world              The famous hello world HTTP server in 6 lines
hello-coffee             The same server written in CoffeeScript
hello-typescript         The same server written in TypeScript
hello-html		         Template with HTML file
template-gradle-java     Gradle Java project
template-maven-java      Maven Java project

Check README.md and sources at /usr/lib/node_modules/nodeclipse or https://github.com/Nodeclipse/nodeclipse-1/tree/master/org.nodeclipse.ui/templates/

For example, we can use the -p option to add a .project directory to the current working directory.

Input

$ nodeclipse -p

Output

user@hostname:~/eclipseNode$ nodeclipse -p
In Eclipse/Enide select File -> Import... -> General / Existing Projects into Workspace
and enter project directory: /home/user/eclipseNode

  Visit http://www.nodeclipse.org/ for News, post Shares, Installing details, Features list, Usage (incl Video, Demo) with all shortcuts, Help and Hints, Support options, Where Helping needed, How to thank and Contact us, also History page.

Now launch the Eclipse IDE and import the project directory by following this path:

  1. File → ImportGeneralExisting Projects into Workspace.
  2. Click the Next > button and paste the project path into the search box.
  3. Click on the Finish button.

Update the files with the following content.

package.json

{
  "name": "eclipsenode",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "type": "module",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "express": "^4.18.2"
  }
}

We configure the application to use ES modules

"type": "module"

For example, we can import the express module in the index.js file.

 

index.js

import express from "express";
const app = express();

app.use(express.static("public"));

const PORT = process.env.PORT || 3000;
app.listen(PORT, console.log(`Make requests at http://localhost:${PORT}`));

We import express and create a web server that listens for requests on 3000. On making a request on localhost, we load static assets stored in the public folder.

 

public → index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="style.css">
    <title>How to use node.js with Eclipse IDE</title>
</head>
<body>
    <h1>How to use node.js with Eclipse IDE</h1>
    <h3>Learn how to use node.js with Eclipse IDE step-by-step</h3>
    <h4>by loading this page</h4>
    <h5>with an Express web server.</h5>
</body>
</html>

We create a page with four headings. The page is styled with style.css.

 

public → style.css

body {
    width: 70%;
    margin: 7% auto;
    text-align: center;
    background-color: black;
    color: gold;
}

We center the golden text on the page.

Now we can start the server by clicking on the green run button. The console output appears with the message Make requests at http://localhost:3000.

Open the URL with a browser. We get the expected output.

We can stop the server by clicking on the red button on the right-hand side of the console menu.

Key takeaways

Knowing how to use node.js with Eclipse IDE can be easy if you install the required tools correctly.

For example, this tutorial showed you how to install Node.js and Eclipse IDE step-by-step. Next, you installed Node.js packages and developed a simple web server on the IDE.

Alternatively, you can use Visual Studio CodeAtom, or Sublime.
