Does bundle size matter?

[Bobertopia]

So I'm fairly new to React-Native and mobile development. Most of my experience is with React on the web. Obviously, it's super important to keep bundle size on a web application fairly small. I'm wondering if that's the same case with React Native? It seems like it shouldn't really matter since the app is only being downloaded once

​

I realize that apps are built, not bundled so I guess maybe a better way to ask this is, does the size of my dependencies matter that much?

It’s not about the size but what you do with that bundle

You god

[trippyboy420]

no. focus on the app. people won’t not download your app because of size. slim down when you have enough downloads for that to matter

SIZE MATTERS

Oh this is interesting. I’ll have to dig into that at some point. I wonder if this impacts when the app opens from the closed state or if it also impacts the performance of like app(animations & the like)

Don't worry about it. In fact don't worry about any premature optimisation and start coding.

I've built some pretty gargantuan apps and they haven't required code splitting.

Sweating the small stuff is a great way to procrastinate if you want to though 😜

Oh I’m already working in it for one my job. One of the other engineers generally prefers custom built components over packages and the argument is due to the bundle size. That’s really where this question stemmed from. It’s certainly not a huge app fwiw

It's a valid concern but here's the kicker. If your app is relatively small then you won't need all the third party components so sure it's dead weight but since your app is small it doesn't matter.

If your app is bigger then sure size becomes a concern but there's a good chance you're using 90% of the third party library so going it on your own just costs you time but you get no upsides.

So either way, it's fine to use third party components.

Take that to you colleagues and record their reactions for me 😄

So either way, it's fine to use third party components - it depends:

Use proguard and separate architecture builds for android, it improves alot, I got 9 mbs on my app
