Install a tool called nodemon that automatically restarts the node application when it detects any changes.

Install the express library and add it to the package.json file as a dependency.

It will ask for the package’s name, version, and many others (you can go with defaults by pressing ENTER). This will add the package.json file, which holds information about our projects like scripts, dependencies, and versions. Now, initialize the node project using the following command.Now, create a file named app.js as follows.To create a folder named express_app and move inside the folder using the following commands.Let’s start with an effortless express application that prints “ Hello World! This is Nodejs from a docker container” on visiting the root endpoint. Many companies are shifting to using dockers because an application running on docker is more maintainable, easily modifiable, and highly scalable. Then a developer can share this image with others to have the same environment as the developer does and run the application.Ī docker container is the best tool for microservice architecture adaptation. It is required to run an application along with their versions. One might develop their local system, which might be totally different from a cloud instance where the application is finally deployed.Ī docker container solves this problem, and It uses the concept of images that stores a record of a docker container at a particular time like all the libraries. One of the problems developers face is having different environments for the development of an application and in the deployment of the same.
