How to start a Node.js project
Introduction:
Start Node. js project involves running the application on the local machine for execution and testing. The following steps provide detailed guidance to help you get started with your Node.js project.
Step 1: Install Node.js
If you haven’t installed Node.js yet, please download and install the latest version from the official website.
Step 2: Install project dependencies
Use a package manager such as npm or Yarn to install project dependencies. Go to the project directory and run the following command:
- Using npm:
npm install
- Using Yarn:
yarn install
Step 3: Create startup script
In the package.json
file in the project directory, add a "scripts" object. Within that object, create a script with the name "start" as shown below:
<code>"scripts": { "start": "node app.js" }</code>
Replace "app.js" with your application entry file.
Step 4: Run the startup script
In the project directory, run the following command to start the project:
- Use npm:
npm start
- Using Yarn:
yarn start
Step 5: View project output
The startup script will execute your application and output any logs or messages to your console.
Additional Tips:
- Use the
nodemon
package to automatically reload your application's changes. - Use the
forever
package to create applications that run in the background and automatically restart. - For production deployments, consider using a container orchestration tool such as Docker or Kubernetes.
