How much memory can I use in my JavaScript app in Browser?

Question

I’m developing a JavaScript App (using React, Redux...). My app need some metadata to work, to display objects in trees or in tables...

I’m just wondering if I should load all these metadata from the server in one shot and keep them in a memory or if I should perform each time requests to get only what I need to minimize the memory footprint.

My data are not so big, maybe 1 or 2 MB.

I wonder how much memory I can rely on in general in browser ?

What is the order of magnitude 10MB, 100MB, 1GB...?

You could use localStorage since the browser stores It on computer's disk — Lucas David Ferrero, Mar 30 '18 at 17:30

There's no upper limit. However, being conservative in memory usage is smart. Nobody likes a hungry web application.

Yes, You can use based on browser,but max you can check with these code in console

window.performance.memory.jsHeapSizeLimit

If you are using chrome 32 bit, then JS heap is limited to ~756MB
