![]() ![]() ![]() I published a GitHub repo for this tutorial so you can compare your code if you get stuck. Instead, we’ll focus on showing how requests from the interface are recorded into a database. We won’t cover how to validate data before interacting with the database. I’ll assume that you understand how a React application works and are familiar with frontend JavaScript HTTP requests. We’ll then create a simple React app to test and see how the entire application flows from front to back. In this tutorial, we’ll demonstrate how to create a small application using Express and Node.js that can record and remove information from a PostgreSQL database according to the HTTP requests it receives. Knowledge of both frontend and backend programming - as well as designing scalable systems and building solid application architecture - is a requirement to be a tech lead.You can be promoted to a full-stack developer and take on a bigger role with a higher salary.You’ll be able to work on both the front and back side of your app.You’ll stand out from other frontend developers because you’ll know how your application work as a whole.That said, there are plenty of good reasons for a frontend developer to learn about backend programming and database interaction. Getting started with Postgres in your React appįrontend developers typically don’t need to understand the process of receiving, recording, and removing information.
