node.js - How to fix "FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory" error

Question

I'm trying to deploy a reactjs application to heroku. While compiling assets, the build fails and produces this error:

-----> Ruby app detected
-----> Compiling Ruby/Rails
-----> Using Ruby version: ruby-2.5.1
-----> Installing dependencies using bundler 1.15.2
       Running: bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin -j4 --deployment
       Warning: the running version of Bundler (1.15.2) is older than the version that created the lockfile (1.16.3). We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.

I've tried various methods in my package.json file:

"scripts" : {
   "start": "cross-env NODE_OPTIONS=--max_old_space_size=5120 webpack"
}

"scripts" : {
  "webpacker": "node --max-old-space-size=4096 node_modules/.bin/react-scripts start"
}

"scripts" : {
  "start": "node --max-old-space-size=6144 client/app/app.js"
}

I've researched

Answer 1

I had a similar heap allocation error while deploying to Heroku. The app would still build correctly but would not load in the browser. Heroku logs would show me this: FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

After trying a dozen different things this seemed to work in package.json:

 "start": "react-scripts --max_old_space_size=4096 start",
 "build": "react-scripts --max_old_space_size=4096 build",
