FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory 1: node_module_register 2: v8::internal::Factory::NewStruct 3: v8::internal::Factory::NewPrototypeInfo

I tried everything. I reduced the usage of variables and checked for memory leaks and made very less callbacks in the ts file.

Im unable to figure out how to do it. I tried increasing the node memory by using 'npm i increase-memory-limit' and increased the limit to 2GB.

Im using angular 4. Node version is 8.9.4

Try navigate to yourproject/node_modules and run following mand:

node --max_old_space_size=5048 "%~dp0\..\@angular\cli\bin\ng" build --aot --prod

And if you want to make your life easier you can insert this in your package.json file:

"scripts": {
   "build-prod": "node --max_old_space_size=5048 ./node_modules/@angular/cli/bin/ng build --prod"
}

Then all you have to do now is running npm run build-prod.

You might want to look at how increase-memory-limit increases the heap size under the hood.

The usual way is as follows:

node --max-old-space-size=8192 server.js  

If it is somehow modifying the ng build mand you may want to try increasing the limit more.

I am getting this error while running

npm test run

For temporary, we can increase limit of --max_old_space_size

path: node_modules/@yarnpkg/index.js

then search for --max_old_space_size and then increase limit but it will be a temporary solution.

try this as it seems like permanent solution-- https://stackoverflow./a/57782016/1948482

I had the same problem once building a JS application and it turns out there's a limit of the memory a node module can consume.

simply using this npm package has solved it for me : https://www.npmjs./package/increase-memory-limit
