Realm-js: Compiling Realm on electron yields 200+MB realm-js resources directory

[connormakh]

I'm using electron-builder to build a desktop app written in React, one of my dependencies uses realm-js. It builds fine, but the Realm folder in my packaged app's Resources folder is 240MB, pushing my app to a hefty size of 500MB.

Version of Realm and Tooling

• Realm JS SDK Version: 2.19
• Node or React Native: Node.js
• Client OS & Version: Mac OS - 10.14.1

@connormakh Did you try to figure out why? And what the content is?

[connormakh]

Inside my Resources folder,
realm > vendor > realm-mac-x64 > osx
There are a bunch of .a files:

librealm.a -- 5.8mb
librealm-sync.a -- 2.6mb
librealm-sync-dbg.a -- 59.2mb
librealm-server.a -- 2.3mb
librealm-server-dbg.a -- 60mb
librealm-parser-dbg.a -- 25mb
librealm-parser.a -- 2.9mb

The above seem to be the issue. Is it normal for the file size to be this big?

I wonder why there are debug versions of the binaries and why there is librealm-server.

[connormakh]

Not so sure, correct me if I'm wrong, but i think its unnecessary in a production environment for these files to exist

[nirinchev]

Right, this was more of a question for our JavaScript team 😅 We need to figure it out and fix it.

While checking my node_modules, realm folder size is almost 1.09GB. Thats really huge.
I am using it in react-native project and installed it using npm.
Was wondering why such a huge size.
Can we reduce this size?

This might help in the meantime: https://github.com/iotaledger/trinity-wallet/blob/cb5f1df5201a0e1735d06cc229daa85c2533a346/src/desktop/package.json#L81-L86

With these settings, the Mac version of our app turns out to be 223.5MB.

I don't see anything related to Realm in the Resources folder either:

@connormakh - how did you compile realm?

[connormakh]

@trickyc0d3r i was compiling it via electron-builder

In any case, @rajivshah3's solution is what i ended up going with
