Node.js Project to Download CSV Files From URL Using Request Pipe() Stream Method

Welcome folks today in this blog post we will be downloading csv files from url using request pipe() stream method. All the full source code of the application is shown below.

Get Started

In order to get started you need to install the request module using the npm command as shown below

npm i request

After that you need to make an index.js file and copy paste the following code

index.js

const request = require('request')

const fs = require('fs')

const url = "https://peoplefssdf.sc.fsu.edu/~jburkardt/data/csv/faithful.csv"

const file = fs.createWriteStream('output.csv')

const request = require('request')

const fs = require('fs')

const url = "https://peoplefssdf.sc.fsu.edu/~jburkardt/data/csv/faithful.csv"

const file = fs.createWriteStream('output.csv')

As you can see we are importing the request module at the very top and then we are declaring the csv file url where we will be downloading it and saving it inside the local disk. And then we are declaring the output filename using the createWriteStream() of the fs module.

request(url)
.pipe(file)
.on('finish',() => {
    console.log("file is successfully downloaded")
})
.on('error',() => {
    console.log("file url is incorrect")
})

request(url)

.pipe(file)

.on('finish',() => {

console.log("file is successfully downloaded")

})

.on('error',() => {

console.log("file url is incorrect")

})

As you can see we are using the request() module and then passing the url inside it and then we are using the pipe() method to download the csv file stream from the url. And then we are listening on for various events such as finish and error events.
