Is there a list of flags for Node.js?

Question

I'm trying to find a list of all flags that Node.js accepts, specially those for ES6-Harmony features, but I can't find any. Is there anything like this?

Answer 1

Run node --v8-options. That displays the various flags you can set to change the behavior of V8

E.g. The flags for the harmony features show up in there:

 --harmony_typeof (enable harmony semantics for typeof)
     type: bool  default: false
 --harmony_proxies (enable harmony proxies)
     type: bool  default: false
 --harmony_weakmaps (enable harmony weak maps)
     type: bool  default: false
 --harmony_block_scoping (enable harmony block scoping)
     type: bool  default: false

Answer 2

If you apply the --help switch to node from the shell, you'll get a list of available flags;

node --help
