zip file and download from client or server?

Question

I need to pull a set of arrays, they have values like ' http://example.com/1.png ' and I have to zip and download them when a user click 'download' on the cilent side.

For that part should I do it on server or client side? I found few npm that can do the job but I doubt it should be at the server side, since I can pass my data from db to cilent.

Answer 1

For Server Side:

First You Can Make Use Of A NPM Module Called ADMZIP; And Pack The ZIP TO ADMZIP Object in nodejs side. And Send The Content in response From The Server Side Using ExpressJS(sendFile or download)

For Client Side:

You Can Create A BLOB On The Client Side And Retrieve The Response And Then Download The Content

Downloading and saving files from server using AngularJS

Answer 2

In the case of zipping files on a frontend(using jszip for example) client probably will download images faster because most modern browsers can have 6 downloads at the same time, but on another hand, it has it's own limitations and issues .

So I would suggest using server-side compression because it's more stable and flexible(using node-zip for example).
