Nodemon compatibility with io.js? #468

mitchdenny · 2015-01-18T07:50:54Z

Some folks have reported an issue with compatibility between io.js and nodemon. Might be worth the nodemon maintainers spinning up an install of io.js just to check. It might be easier for you to find the issue since you understand your own app architecture:

nodejs/node#485

remy · 2015-01-19T06:22:45Z

Are you using the execMap for io.js or letting nodemon use the node alias to io.js?

kyrylkov · 2015-01-19T06:44:32Z

Alias: 'nodemon -e html,css,js server.js'

netmiller · 2015-01-19T06:58:03Z

I am using exeMap, but it did't help :

{
  "verbose": true,
  "execMap": {
    "js": "iojs"
  }
}

remy · 2015-01-19T09:52:37Z

Okay, cool, I'll give this another try (I thought I tested it and it worked
tho).

Can you also share what OS you're running with any extra details?

netmiller · 2015-01-19T13:25:25Z

Sorry, forgot to mention. Using OS X 10.9.5 and nodemon is installed as global.
If you want some verbose_messages I can send, but I can't see anything suspicious there...

remy · 2015-01-19T19:36:29Z

I'm on Mac OS X 10.9.5 also, and it's working fine for me:

I'm using a ~/nodemon.json that looks like this:

{
  "execMap": {
    "js": "iojs"
  }
}

Anyone able to dig a little deeper to work this out with me?

Note that my install process for io.js was:

Install node.js (many months ago).
Install io.js (last week) - noticed that now node on the command line was aliased to iojs, so -
Re-install node, and now I can use node as node and iojs as io.js

I suspect others don't have the step 3, which might be hiding some issue...

kyrylkov · 2015-01-19T20:00:27Z

@remy I don't have node installed at all right now, only io.js

netmiller · 2015-01-19T20:09:28Z

Nodemon get it's output fine, but console.log inside my main.js script is not visible. I have Express-application; haven't tried with pure node. I will do it this evening.

With nodemon :

Esan-iMac:iris$nodemon main.js
19 Jan 21:57:13 - [nodemon] v1.2.1
19 Jan 21:57:13 - [nodemon] reading config /Users/esa/devel/iris/nodemon.json

19 Jan 21:57:13 - [nodemon] watching 15,612 files
^C19 Jan 22:04:47 - [nodemon] exiting

and it should be something:

Esan-iMac:iris$node main.js
 >> node-dev-mode-enabled.
{ [Error: Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND' }
js-bson: Failed to load c++ bson extension, using pure JS version
=> Iris listening on port 9042 /no-SSL/w:dev

js-bson error is due to something with MongoDB (connect-mongo@0.6.0) , but 2 other rows should come by 'console.log'
(f.ex. last row .... => Iris listening on port .....)

remy · 2015-01-19T20:15:19Z

Can you replicate with an io.js script that you can share (via a gist perhaps)?

netmiller · 2015-01-19T20:17:38Z

And with node-supervisor it shows :

Esan-iMac:iris$supervisor main.js

Running node-supervisor with
  program 'main.js'

  --exec 'node'

OK, I put mine 'main.js' script in some gist. It takes some time; have not used Gists for a while.

remy · 2015-01-19T20:19:31Z

I'd suggest trying to get it down to something really small and basic - rather than your whole main.js. If only to keep things sane!

netmiller · 2015-01-19T20:26:52Z

Whole 'main.js' is in gist : https://gist.github.com/netmiller/520957cc727950c69a8d

It's not very big script; only a bunch of Express-specific 'require' s etc.
But you can easily find few console.log messages I'm using.

remy · 2015-01-19T20:29:52Z

Yeah, I'd need the package.json for all the deps - which is why I said I
wanted a simple main.js...

I will try to generate some simple Express-app later this evening.
Meanwhile my package.json is here :

Anyway; pure node start works fine, and also supervisor is working without problems. Can't help much, but I'll try to make really simple test script soon.

remy · 2015-01-19T20:49:54Z

Are you using the execMap? I'm assuming not, but just checking.

remy · 2015-01-19T20:53:55Z

@netmiller I ran your package and main.js:

netmiller · 2015-01-19T20:54:10Z

OK, I created new Express script according 'Hello World' -tutorial.
Really simple, only 'require' is Express itself.

Here is results :

Esan-iMac:iris$node test10.js

and this is my test10.js script :

var express = require('express');
var app = express();

app.get('/', function (req, res) {
  res.send('Hello World!');
});

var server = app.listen(3000, function () {
  var host = server.address().address;
  var port = server.address().port;
  console.log('Example app listening at http://%s:%s', host, port);
});

No dependencies; only I created this script to same directory where are all my deps with "full app". But it should't make difference, or am I missing something.

+ +

Yes, I'm using execMap .

remy · 2015-01-19T20:55:47Z

I get this (with your updated main.js):

» nodemon main.js
19 Jan 20:55:18 - [nodemon] v1.2.1
19 Jan 20:55:18 - [nodemon] to restart at any time, enter `rs`

19 Jan 20:55:18 - [nodemon] starting `iojs main.js`

What do you see (can you paste)?

netmiller · 2015-01-19T20:56:06Z

Try this test10.js script, and install only latest Express.
I will do the same into clean directory.

remy · 2015-01-19T20:56:49Z

Can you share your /Users/esa/devel/iris/nodemon.json file too (if that's suitable)?

netmiller · 2015-01-19T20:58:53Z

This is all I got into terminal (test10.js) :

Esan-iMac:iris$nodemon test10.js

and here is nodemon.json

Esan-iMac:iris$cat nodemon.json
{
  "verbose": true,
  "execMap": {
    "js": "iojs"
  }
}

netmiller · 2015-01-19T20:59:41Z

Don't understand what is the difference; trying to install same into clean dir soon.

remy · 2015-01-19T21:02:37Z

Hmm, weird. I might try to reinstall iojs (which will kill off node), there might be something in that.

netmiller · 2015-01-19T21:09:23Z

Making new/clean directory and installing Express (nothing else) and copying simple 'test10.js' into it :

Esan-iMac:test24$npm install express
express@4.11.0 node_modules/express
├── merge-descriptors@0.0.2
...etc

Esan-iMac:test24$cp ~/devel/iris/test10.js .

Still this 'console.log' is not visible running via nodemon.
This time I have't execMap, but nodemon is still installed as global?
Can it make some difference; I guess no....

netmiller · 2015-01-19T21:14:03Z

Tried to install nodemon locally, but no difference (= no 'console.log' output).
It must be something with iojs.
Maybe I can install latest node again and test if it works with "pure" Node.js.

netmiller · 2015-01-19T21:20:28Z

Yes, one step forward. Installed pure Node .pkg (v.0.10.33) and simple 'test10.js' works now. It must be inside 'iojs.js'.

Esan-iMac:test24$node -v
v0.10.33

Esan-iMac:test24$nodemon test10.js
19 Jan 23:15:49 - [nodemon] v1.2.1

No 'execMap', and my /usr/local/bin seems :

remy · 2015-01-19T21:22:37Z

Confirmed it by installing iojs over node.js - and it kills output.

I will investigate.

remy · 2015-01-19T22:00:36Z

Fixed and landed in nodemon@1.3.1.

netmiller · 2015-01-19T22:08:32Z

Très bien, excellent work. Going forward with iojs and hoping all bugs fixed like you did =:)
