Re: [nodejs] Possible to select globally installed module over locally install one?

2015-09-13 Thread Zlatko 
What do you mean, they're not requireable?

[zlatko@zlatko-mint /tmp]$ node -e "require('express')"
module.js:338
throw err;
  ^
Error: Cannot find module 'express'
[...cut...]

[zlatko@zlatko-mint /tmp]$ npm i -G express
\
[...cut...]

[zlatko@zlatko-mint /tmp]$ node -e "require('express')"
[zlatko@zlatko-mint /tmp]$ 


For the OP, it's possible to do it manually, ie: `
require('/home/zlatko/.nvm/versions/node/v4.0.0/lib/node_modules/gulp');` 
but it's not very scalable.

The problem is - when I bump my node version to, say, 4.0.1, I'd have to 
fix the path. Also, if it were you, you would not have a `/home/zlatko` 
part, but possibly /usr/lib/node_modules or similar.


I don't know if there's a node config option for something like that 
though, probably there isn't.

Re: [nodejs] Domain module in nodejs 4.0.0

2015-09-13 Thread Brian Deitte 
Here is the PR that made the change:

https://github.com/nodejs/node/pull/141

And here's an expanded explanation:

https://github.com/nodejs/node/pull/141#commitcomment-8951851

While not ideal, I can understand deprecating if you know a different
solution is needed, even if that solution isn't available.  I've stayed
away from domains myself as I've seen bits and pieces of details through
the years on issues using them and in the implementation of them.

Re: [nodejs] Domain module in nodejs 4.0.0

2015-09-13 Thread Ryan Graham 
That's what the text you quoted says. It's not deprecated yet, but it will
be as soon as there is a replacement.

1. Pending deprecation, looking for an alternative   <-- now
2. Deprecated, will print warnings if you use it<-- probably
not 4.x
3. Removed, will fail with undefined method or similar errors

Re: [nodejs] Domain module in nodejs 4.0.0

2015-09-13 Thread Charles Dumas 
I tend to agree on no longer using domains and just trying to restart the 
process gracefully. The documentation seemed to imply that a new solution 
was already in the works and I was curious as to what that solution was. 

Thanks everyone for the answers

Probably means that globally installed modules are not intended to be used in a 
require statement, and users should not attempt to find a way to do so.

You misspelled -g as -G, npm ignored you, and installed it locally. :-)

Do an "ls node_modules/express", and you will see.

Re: [nodejs] Node/Express best practice regarding multiple apps on 1 instance

If you're just testing a node app, you can start it on the command line, no 
problem.

If you want that app to run a production web site, you'll want to take care of 
two things:

1. starting your node app when the your boots (even if you don't plan to reboot 
your vps ever, it might reboot for reasons outside of your control, including 
the whims of your hosting provider and unexpected power loss)

2. restarting your node app if it quits (most node apps are designed to quit 
when they encounter an unexpected situation, and also your app might crash)

On OS X, launchd would handle both of those things, if asked to do so via a 
config file (plist) that you would write. On Linux variants that use systemd, 
it would handle both, again if so configured. AFAIK the majority of Linux 
variants do not use systemd, so you may need to handle these two things 
separately, using whatever facilities are built into your flavor of Linux, or 
using other tools. I don't use Linux so I can't guide you specifically.
