Hi Koray,

Apparently, the answer to your original question is "yes", functions 
generated by "eval" or "new Function()" will get optimized. I've asked one 
of the V8 developers on Twitter, he even referred on how Webpack (pretty 
popular and well known JavaScript package) achieves crazy improvements on 
their latest iteration:

Hi
You can take a look at Node's VM module. (require use that module
internally).

Hello,

Thanks for your response. Main reason is I'm mostly a beginner so for
the time being this is the only way I know. There will be multiple
active sockets at any given time and they will be interacting, so I
want to be able to roll changes in without having to restart.

[nodejs] Re: Are functions which defined using eval or new Function() optimized?

2018-03-02 Thread Zlatko 
Hi,

Good question! V8 Googlers say nothing eval does is optimized and almost 
absolutely must be avoided (and they same for Function constructor IIRC) - 
but what about the product of it?  I don't know, maybe you can run a few 
tests with v8-debug. I would be interested in results if you do run such a 
test.

But I have another question: why would you deploy new code this way? Can't 
you have some continuous deployment, partial rollouts etc this way? Or send 
all requests for unknown functionality to a pubsub, and then attach your 
new code there to respond?
