Get a File Name Before Saving It

I have a request that is supposed to download a file from remote api. What I want is, however, to save this file with the same name which it is saved with when I download the file from browser. For example, I have an URL , and when I click this link, browser immediately starts to download a file from that URL with name myfile20180601.txt. How do I save the file with the same name if I make a request from Node.js? This is my code:
axios({
method: 'get',
url: '
responseType: 'stream',
headers: {
Authorization: 'Basic KJVEB46287blablablatoken'
}
})
.then(res => res.data.pipe(fs.createWriteStream(`${/* filename */}.txt`)))
.catch(err => console.error(err));

You can find your filename in the response of axios
var axios = require('axios')
var fs = require('fs')
axios({
method:'get',
url:'
responseType:'stream'
})
.then(function(response) {
- let headerLine = response.data.headers['content-disposition'];
+ let headerLine = response.headers['Content-Disposition'];
let startFileNameIndex = headerLine.indexOf('"') + 1
let endFileNameIndex = headerLine.lastIndexOf('"');
let filename = headerLine.substring(startFileNameIndex, endFileNameIndex);
response.data.pipe(fs.createWriteStream(filename));
});
Hope this response helped you
I believe this will help!
let filename = response.headers['content-disposition'].split('filename=')[1].split('.')[0];
let extension = response.headers['content-disposition'].split('.')[1].split(';')[0];
console.log(`${filename}.${extension}`)
It has already been answered for backend, here i'm posting the answer for frontend.
You can get the browsed file name in by accessing the event --> event.target.files[0].name
Ex:
onChange={(event) => {
const fileName = event.target.files[0].name;
console.log('fileName', fileName);
}}
