Learn Express.js | Lecture – 3: Creating a new project ( EmployeesApp )

Welcome to Lecture 3 of our Learn Express.js series. In this lecture, we will be creating a new project called “EmployeesApp”. We will walk through the steps of setting up a new Express.js project and getting it ready for development.

If you haven’t already installed Node.js and Express.js, please make sure to do so before continuing with this lecture.

Setting up the project

Open your terminal and navigate to the directory where you want to create the project. Once you’re there, run the following command to create a new Express.js project:

$ express EmployeesApp

This will create a new directory called “EmployeesApp” with the basic structure of an Express.js project. Next, navigate into the newly created directory:

$ cd EmployeesApp

Installing dependencies

Now that we have our project set up, we need to install the necessary dependencies. Run the following command to install the required packages:

$ npm install

This will install all the dependencies listed in the “package.json” file, including Express.js and any other packages required for the project.

Starting the server

Once the dependencies are installed, we can start the server by running the following command:

$ npm start

This will start the server on port 3000 by default. You can navigate to “http://localhost:3000” in your web browser to see the default Express.js welcome page.

Building the app

With the server up and running, you can now start building your EmployeesApp. You can create new routes, define models, and set up the database as per your requirements for the app.

Conclusion

Congratulations! You have successfully created a new Express.js project called “EmployeesApp” and have it up and running. In the next lecture, we will dive deeper into building the app and adding more functionality to it.
