The memory heap out issue occurs when the heap size is not sufficient to run the application. To resolve this issue, open the package.json
file, which can be found in the root folder of React application and use --max_old_space_size=4096
as like in the below code snippet.
...
...
"scripts": {
"start": "react-scripts --max_old_space_size=4096 start",
"build": "react-scripts --max_old_space_size=4096 build",
"test": "react-scripts test",
"eject": "react-scripts eject"
}
