Description

ng serve accept node flags

Describe the solution you'd like

Something like proxy-conf.json

ng serve --node-config=node-conf.json --proxy-config proxy-conf.json

https://nodejs.org/api/cli.html

{
 "max-http-header-size": 100000,
...
   
}

Describe alternatives you've considered

• recompile node with custom flags, not good idea
• downgrading node

There's already a pretty decent way of doing that, which is to call node with the path to the ng binary. We recommend doing so for increasing available memory for instance.

In your case I think you could do this:

node --max-http-header-size=100000 ./node_modules/@angular/cli/bin/ng serve

But you could also use the NODE_OPTIONS env var in the link you provided. There's isn't a great usage example there, but https://medium.com/the-node-js-collection/node-options-has-landed-in-8-x-5fba57af703d explains it better. With that, you'd do this instead on Linux:

NODE_OPTIONS="--max-http-header-size=100000" ng serve

On windows you'd have to use a method for setting env vars that works with your shell (these vary a bit).

Hope this helps.
