Node.js - convert image to base64
0 points
In this article, we would like to show you how to convert image to base64 in Node.js.
1. Import fs module
xxxxxxxxxx1
const fs = require('fs');2. Use:
-
fs.readFileSync()to read the data from file toString()method with specified'base64'argument to receive base64 encoded string.
In this example, we create a reusable function that converts image to base64 encoded string.
xxxxxxxxxx1
const fs = require('fs');2
3
// relative path to the img4
const filePath = './img.jpg';5
6
// reusable arrow function to encode file data to base64 encoded string7
const convertBase64 = (path) => {8
// read binary data from file9
const bitmap = fs.readFileSync(path);10
// convert the binary data to base64 encoded string11
return bitmap.toString('base64');12
};13

// Usage example16
const result = convertBase64('img.jpg');17
