Node.js Tutorial to Remove Background From Image Using Rembg & Sharp Library in Command Line

Welcome folks today in this blog post we will be using the sharp and rembg library to remove background from image in command line using node.js. All the full source code of the application is shown below.

Get Started

In order to get started you need to make a new node.js project using the below command as shown below

npm init -y

npm i sharp

npm i rembg-node

And after that you need to make a new index.js file and copy paste the following code

index.js

const { Rembg } = require("rembg-node");
const sharp = require("sharp");

(async () => {
	const input = sharp("1.jpg");

	// optional arguments
	const rembg = new Rembg({
		logging: true,
	});

	const output = await rembg.remove(input);

	await output.webp().toFile("test-output.webp");

	// optionally you can use .trim() too!
	await output.trim().webp().toFile("test-output-trimmed.webp");
})();

const { Rembg } = require("rembg-node");

const sharp = require("sharp");

(async () => {

const input = sharp("1.jpg");

// optional arguments

const rembg = new Rembg({

logging: true,

});

const output = await rembg.remove(input);

await output.webp().toFile("test-output.webp");

// optionally you can use .trim() too!

await output.trim().webp().toFile("test-output-trimmed.webp");

})();

As you can see we have imported the sharp and rembg-node libraries at the top and then we are removing the background from the images and then we are saving it as the webp image.
