Feature Request: Ability to customize heap memory available to node

[quantizor]

I'm not sure what the default heap allocation is, but for some larger projects using webpack etc it's insufficient and the heap allocation needs to be increased via something like this:

export NODE_OPTIONS=--max_old_space_size=4096

It would be great if this could be done in the node setup action via some clean API :)

Hello @probablyup , I am not sure that we should build-in this functionality to setup-node action. It can be achieved easily with the following code snippet as an example:

steps:
- uses: actions/setup-node@v2.1.5
  with:
    node-version: 14.x
- run: npm install
- run: npm run start
  env:
    NODE_OPTIONS: --max_old_space_size=4096

Or you can even specify env variable on job level if it should be applied to all steps. See documentation for more details
