I have files inside one folder and i want to download the folder form node js server. I try some code but it doesn't work. I get some examples about downloading (Downloading folder, How to zip folder )folder but they doesn't work for me or i did't understand them.

I have folder like: Allfilefolder -file1.js - file2.js -file3.js

I can download each file using:

app.get("/files/downloads", function(req,res){ const fs = require('fs'); var filepath = './Allfilefolder/file1.js'; res.download(filepath ); });

But i don't know how to download the folder. any help please?

  • You don't zip any file yet, don't you ? Commented Sep 25, 2018 at 17:29
  • @TGrif yes I didn't zip folder yet. I just want to download folder from node server. For this I think I should have to zip it first. But I don't know how to do it yet. I searched many times but I couldn't find useful things. Could you help me if you have done similar things before. Commented Sep 27, 2018 at 1:52

Assuming you already have a zip software installed and accessible from your app, one way to do it is to use Node.js child_process, this way you don't even have to use an external library.

Here is a basic example, inspired by this concise and effective answer:

// requiring child_process native module const child_process = require('child_process'); const folderpath = './Allfilefolder'; app.get("/files/downloads", (req, res) => { // we want to use a sync exec to prevent returning response // before the end of the compression process child_process.execSync(`zip -r archive *`, { cwd: folderpath }); // zip archive of your folder is ready to download res.download(folderpath + '/archive.zip'); });

You could also have a look at the npm repository for packages that will handle archiving file or directory more robustly.
