Understanding of how a Node.js application is structured. The guide also assumes you have a working Docker The guide is intended for development, and not for a app.The goal of this example is to show you how to get a Node.js application into aĭocker container. Then, create a route for a home url which is “/” using HTTP get() request method. Inside the project, create an index.js file, in there, import express at the top and create an express server and store it in a constant called app. To: "devStart" : "nodemon index.js" Create Index.js file Then go to package.json and replace the property inside the scripts from: “Test”: “echo \”Err” To install nodemon, run the following command: npm install nodemon Nodemon is one of the npm packages that will help us to run the app without restarting the server every single time when we make a change in our project. You can also check for the installed npm packages inside package.json under dependencies object.
Once it’s installed successfully, you can see a folder called “node_modules” and a file called “package-lock.json” added to the project folder. The next step is to install express, which is one of the most popular Node.js web application frameworks, so that we don’t have to get started from scratch. Then open up the Terminal Window, make sure you’re in the project directory, and run the following command which will initialize our project by creating a package.json file inside your project folder. I prefer visual studio as it comes with Terminal. To verify that, open up the Terminal or Command prompt from you computer and run the following commands: node -vĬreate a project folder in your computer and open it up in your favourite editor. Once its downloaded, double click to complete the installation process.Īt this stage you’ve successfully installed Node as well as NPM (Node Package Manager). Go to and download the LTS version of it in your computer. In this Nodejs tutorial, you’re going to learn how to learn how to get up and running with nodejs app in a minutes.įirst make sure you install node and npm in your computer if you haven’t already.
