What is Node.js?
A server, with use of a representational state transfer application programming interface (RESTful API), is an event-driven backend that uses endpoints to perform logic whose result will be transferred to the frontend so that the frontend developer can use it on the client side.
Why Should You Learn Node.js?
We use Node.js on the server-side to test our applications outside of a browser environment. Learning Node.js works great in the creation of real-time streaming apps and those network applications that require significant use of a database.
For these reasons, it is a popular choice to include in our tech stack for our backend service.
How Long Does It Take to Learn Node.js?
Consistency is key as you are developing a habit to learn new things and think like an engineer. How long it will take for you to learn Node.js well enough to set out on a career of your own really depends on the time you can devote to learning.
Ultimately, though, the learning will never truly end. You will eventually become an expert as long as you keep learning. The language and the runtime environment is ever-evolving and learning about those changes will take continued reading and education.

There are many other topics in the Node.js world that can be learned. These topics are the absolute bare minimum you should master to become a well-rounded Node.js Developer. In the next section, after the step-by-step guide, we’ll take a look at some of the more popular free Node.js tutorials to get you started.
Step 3: Build Projects
Here are some ideas to get you started:
- Create a RESTful API that has endpoints to create, read, update, and delete entries in a directory of some sort. Use a NoSQL database to store your information.
- Add on to the first project by adding registration and login endpoints. Allow only logged in users to create, update, or delete an entry.
- Use Socket.io to create a chat application between two people.
Step 4: Progress to More Difficult Projects
Progress towards more difficult projects by adding a frontend to your already created backend project and make it work so it looks great when a user interacts with it online. Try using all kinds of databases to practice using the different types so you know when to choose one over the other. Lastly, take a look at projects you have already created to see if they can be made more efficient.
More advanced project ideas:
- Collaboration tool like Zoom or Google Hangouts
- Web Scraping a Website to Get Information
- URL/link shortener
- Work on an open-source project and create a Pull Request for it
After you have completed these four steps, the world is yours when it comes to creating Node.js applications! In the next section, we will take a look at some of the tutorials and guides to help you get to this point.
