Now let’s test the application and make sure it’s working. You can also make GET requests at the same endpoint and receive JSON objects that you have previously POSTed. Any JSON structure sent to the server will be saved. You can now make POST requests to the root (/) endpoint. The mocking server will listen on port 8000 by default.
In your IDE, open the working directory, and on the server.js file, add the following code. We will use a mock server called ronin.js for this. Once the REST API is created, we can add some code to handle our REST requests. Now create a simple REST API using the following steps. On your local machine, create a directory named node-docker. Now that we have enabled BuildKit, let’s create a simple Docker Node.js application. In case the daemon.json file doesn’t exist on your system, create a new file called daemon.json and then add the following command to the file: If you want to enable docker BuildKit by default, you need to set the daemon configuration in /etc/docker/daemon.json feature to ‘true’. To set the BuildKit environment variable when running the docker build command, run: If you do not have Docker Desktop installed, you will have to manually enable BuildKit. On the Docker Desktop, It is enabled by default for all users.
A text editor or IDE to edit your filesīuildKit enables you to build Docker images.
To build an application, you need to have the following things in place: This allows Node.js to act as a web server on its own without the support of additional software. Nowadays, it is primarily used for non-blocking, event-driven servers like backend API services and traditional websites.ĭocker Node.js uses the Google V8 JavaScript to execute code and has its own built-in library for file, socket, and HTTP communication. It was originally designed keeping in mind real-time and push-based architecture. These Node.js applications are written in JavaScript and can run within this Node.js runtime on Linux, Windows, or Mac OS without changes. Docker Node.js or simply, Node.js is an open-source software platform used to build scalable server-side and network applications.
