Node.js e Express na Prática | Salvando Dados em JSON Passo a Passo

How to Save Data as JSON with Node.js and Express Have you ever wondered how an HTML form sends information to a server and saves that data permanently? In this hands-on project, we'll build a complete application using Node.js, Express, JavaScript, HTML, and CSS, creating an API capable of receiving data from a form and storing it in a JSON file. During development, you'll learn how all the communication between the front-end and back-end works, understanding each step of the process of sending and persisting information. In this project you will learn: ✅ Node.js ✅ Express ✅ Route creation ✅ REST API ✅ POST requests ✅ GET requests ✅ Thunder Client ✅ Fetch API ✅ Async / Await ✅ Try / Catch ✅ JSON.stringify() ✅ JSON.parse() ✅ JSON data persistence ✅ String manipulation ✅ indexOf() ✅ lastIndexOf() ✅ slice() ✅ JavaScript objects ✅ Front-end and back-end integration Chapters 00:00 Introduction and completed project 00:45 Creating the server with Node.js and Express 02:30 Creating the API POST route 07:20 Saving data to a JSON file 10:05 Testing the API with Thunder Client 14:00 Creating the route GET 16:15 Building the Front-end 18:35 Capturing Form Data 20:20 Validating Name and Sector 22:15 Manipulating Strings (indexOf, lastIndexOf, and slice) 24:50 Creating the JavaScript Object 26:20 Try/Catch, Fetch, and Async/Await 29:00 Sending Data to the API 32:35 Displaying the Server Response 35:40 Testing the Complete Project In addition to learning to program, you will understand how the complete flow of a professional web application works. 📌 Project developed step-by-step. 📌 Code available on GitHub. https://github.com/marcoscaldas/Proje...
