Call and entry last allocation Failed - JS heap out of memory

Description

Recently we included the resin-sdk within our React app, which is causing the npm run build command to emit this error:

> node --max_old_space_size=4096 node_modules/.bin/react-scripts build

When we removed the resin-sdk from the code, it built just fine, which made me look into increasing the memory allocation. After doing quite a bit of research, I tried increasing the old space size with: node --max_old_space_size=4096 node_modules/.bin/react_scripts build, but based on the output, it seems like the allocated space has not increased.

Expected behavior

Perhaps I’m misunderstanding, or not executing this correctly, but I’d expect that when arguments are passed into the react-script, it takes them into account when executing the build.

Actual behavior

Whether I input extra parameters or not, I end up with the same output error when building production code.

Environment

Run these commands in the project folder and fill in their results:

1. npm ls react-scripts (if you haven’t ejected): react-scripts@1.0.7
2. node -v: v6.9.4
3. npm -v: 5.0.3

Then, specify:

1. Operating system: Mac OS Sierra V 10.12.15
2. Browser and version: Safari 10.1.1

Thanks sourcemap: false in webpack.config.prod.js really worked for me

export NODE_OPTIONS=--max_old_space_size=4096 this can help…
