Read Native accessing large file - react-native

I have a 8MB JSON file I need to access once when my application is opened.
Having the file in native assets and reading it over bridge is too slow. Using react-native-fetch-blob, the file is read by android in less than half second, then invoking resolve on the Promise (from Java) takes about 15 seconds.
Having it as a JSON file in the JS space, I cannot build the project, getting the error:
FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap
out of memory
The same issue is reported here, but no progress.
Anyone has faced this problem before?

how to solve module build failed after changing file extension ( *.ts => *.tsx )?

after changing a specific file's extension from .ts to .tsx I get:
Compiled with problems:X
ERROR in ./src/components/SomeComp/someFile.ts
Module build failed (from ./node_modules/source-map-loader/dist/cjs.js):
Error: ENOENT: no such file or directory, open '.../someFile.ts'
ERROR
No files matching 'C:\Users...\src\components\SomeComp\someFile.ts' were found.
it has happened recently and somehow figured out on its own,
then i switched branches and when returned it happened again
I tried what was suggested here, clearing the browser cache How to get Chrome to reload source maps?
also restarted the react dev server couple of times
but still it tries to find the file with the old .ts extension...
searched as much as I could but didn't find a solve...
edit:
after changing the extension back and forth and restarting the dev server it has figured out, but I would still love to know what was happening and what perhaps what should be done to handle this situation correctly in the future

An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2)

I'm getting such error, while building IOS app in React Native project:
was encountered processing the command (domain=NSPOSIXErrorDomain,
code=2) Print: Entry, ":CFBundleIdentifier", Does Not Exist
I read threads in GitHub regarding that issues, however didn't find solutions there which could solve my problem. Any ideas how to fix it?
The cause might be that you have some build files from the previous build which are causing the problem.
Clear the ios/build/your_project to trigger a fresh build
In my case the Xcode build folder needed to be cleaned. To fix, in Xcode go to Product | Clean Build Folder
In my case, the cause was - The build file name was MyMob.app but the app it tries to install to the simulator was mymob.app.
I solved it by changing the line in mymob.xcscheme:46
BuildableName = "MyMob.app"
BuildableName = "mymob.app"
Log was
iinfo Installing "build/mymob/Build/Products/Debug-iphonesimulator/mymob.app"

Switching to Xcode 8.2.1 causes BRCloudDocsErrorDomain

When I switched from Xcode 7.3.1 to Xcode 8.2.1 I get the following error when I try to save (via Cmd+s) the first time.
[ERROR] Failed getting container for URL: file:///Users/bob/Desktop/,
error: Error Domain=BRCloudDocsErrorDomain Code=12 "App library not
found: 'com.apple.Desktop'" UserInfo={NSDescription=App library not

When I tried to disable iCloud Drive from System Preferences.. I instead get the following error.
[ERROR] Failed getting container for URL: file:///Users/bob/Desktop/,
error: Error Domain=BRCloudDocsErrorDomain Code=2 "Logged out - iCloud

I am creating a MacOS app and I do not need to use Cloud, but it seems that the cloud is somehow involved when saving a document. What is the problem here and what can be done about it?
I encountered the same problem and I solved it by switching on Sandbox and by selecting which folders I wanted to use in my project parameters.
Hope that this help you

OSX App doesn't start(Buid succeeded)

Problem: I am unable to launch my OSX app.
Software versions:
XCode Version 8.1 (8B62)
macOS Siera 10.12.1 (16B2657)
I've already tried:
I don't have any changes in my version control.
Also it works fine on my colleague's computer
I've already tried to clean, Also used deep clean
I've overloaded my mac twice
I've already removed derived data
But still unable to run OSX app. It just build successfully all the time and isn't going to launch my app.
I googled about it.
https://www.google.com/search?q=xcode+%22build+secceded%22&oq=xcode+%22build+secceded%22&aqs=chrome..69i57.12138j0j7&sourceid=chrome&ie=UTF-8#q=xcode+%22build+succeeded%22+%22App+doesn%27t+run%22
But haven't found something helpful.
Any suggestions? Probably I missed something... but I think it is a system bug. And I have to clean or relaunch something. But I've already tried all what I was able to guess.

Any way. thanks for attention.

EPIPE error uploading img to s3 using imagesquish

I've been testing imagesquish for a while and I can't seem to have it working.
It works with node.js, forever, express and knox and basically does image processing on the fly.
I'm trying to call an image on a server, it resizes, crops or whatever and then uploads to s3.
I've had permission issues but after creating a new s3 bucket, it seems I made some progress but then, the image doesn't get uploaded and I can't get any error.
I managed to go through it's code and go all the way to exports.uploadImage that would call img.toBuffer but apparently it doesn't get called.
At the end, I get the error:
events.js:72
throw er; // Unhandled 'error' event
^
Error: write EPIPE
at errnoException (net.js:904:11)
at Object.afterWrite (net.js:720:19)
error: Forever detected script exited with code: 8
error: Script restart attempt #1
I need some help on this. Does anybody have any idea?
Luis. Not sure if you're still interested in an answer to this. I'm the author of ImageSquish. From the information you provide, this sounds like img.toBuffer is failing which is usually because graphicsmagick is not installed. The latest version of ImageSquish checks for the existence of this library on startup (see https://github.com/dmcquay/imagesquish/blob/master/check.js).
You might also find it easier to try it out using docker (https://registry.hub.docker.com/u/dmcquay/imagesquish/) so you don't have to worry about installing anything.
If this doesn't resolve your problem, you can find me via irc on freenode #imagesquish.
