How to Fetch and Insert Images to MySQL using React, Fetch API, and Node.js
In today's digital age, managing images effectively in web applications is a common task developers face. If you're wondering how to insert an image into a MySQL database using React for the frontend and Node.js for the backend, you're in the right place! This guide will walk you through the process step-by-step while addressing common pitfalls.
The Problem: Inserting Images into MySQL
When building applications, you might encounter a situation where users need to upload images. You might attempt to send the image data to your backend using a GET request. However, images are binary files and cannot be sent directly through this method. Instead, you should use a POST method to handle the image upload efficiently.
The Solution: Using POST Method with Fetch API
Step 1: Set Up Your Node.js Backend
Your Node.js backend will need to handle incoming requests that include image data. Below is an example of how you might adjust your code to handle image uploads.

Step 4: Displaying the Image
Once the image is successfully uploaded to the MySQL database, you can retrieve it using a GET request and display it using an <img> tag in your React component.

Final Thoughts
By following these steps, you can effectively manage image uploads in your applications using React, Fetch API, and Node.js. Remember that working with binary data often requires you to deviate from typical practices like GET requests, hence utilizing POST for uploads. With this knowledge, you can enhance your applications by integrating robust image handling capabilities.
