Node.js Express Tutorial to Download Multiple Files at Once Using express-zip Library in Javascript

Welcome folks today in this blog post we will be downloading multiple files at once using express-zip library in browser using node.js and express in javascript. All the full source code of the application is shown below.

Get Started

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

npm init -y

npm i express

npm i express-zip

Now we need to make the index.js file and copy paste the following code

index.js

var app = require('express')();
let zip = require('express-zip')

app.get('/', function(req, res) {
  res.zip([
    { path: 'file1.pdf', name: 'file1.pdf' },
    { path: 'file2.pdf', name: 'file2.pdf' }
  ]);
});

app.listen(3000);

var app = require('express')();

let zip = require('express-zip')

app.get('/', function(req, res) {

res.zip([

{ path: 'file1.pdf', name: 'file1.pdf' },

{ path: 'file2.pdf', name: 'file2.pdf' }

]);

});

app.listen(3000);

As you can see we are importing the express and express-zip libraries at the top and then we are making the get route at the / homepage and inside it we are using the zip() method inside which we are passing the array of files in which we have two properties in which we are passing the path of the file and then we are passing the filename of the file to be compressed and then we are starting the node.js and express at port 3000.
