Answer 1

Use node --max_old_space_size=5000 yourapp.js to allow 5000 mb. Look in your eclipse launch settings for command-line parameters, where you can add this.

However, as the comments say, you should reconsider loading this into memory, and stream it to the client instead.

Answer 2

you could add the following to your package.json

"scripts": {
    "start": "node --max-old-space-size=102400 ./app.js",
     ......
}

this is unlike the other way has to write only once and configured each run time. Note: you no need to run explicitly this command the npm start will take care of configuring it each time
