Question:
How to access Node.js in Meteor.js?
Tags: node meteor npm

Meteor.js is a JavaScript framework to help me build web apps.

When I install it on my laptop, I get a copy of Node.js embedded inside.

How do I access that copy of Node.js?

I start the discussion with a screen dump of me installing Meteor.js:

I like to know what the install script does so I figure out what tar-ball it wants.


dan@feb ~/Downloads $ 
dan@feb ~/Downloads $ grep RELEASE meteor_ins.sh
RELEASE="1.0.3.1"
TARBALL_URL="https://d3sqy0vbqsdhku.cloudfront.net/packages-bootstrap/${RELEASE}/meteor-bootstrap-${PLATFORM}.tar.gz"

The install script wants this tar-ball:

Now I untar the tar-ball:

dan@feb ~/Downloads $ rm -rf .meteor

dan@feb ~/Downloads $ 


The tar-ball gave me .meteor/


dan@feb ~/Downloads $ 
dan@feb ~/Downloads $ du -sh .meteor/
434M	.meteor/
dan@feb ~/Downloads $ 


I copy .meteor to my home-folder:


dan@feb ~/Downloads $ 
dan@feb ~/Downloads $ mv .meteor ~
dan@feb ~/Downloads $ 
dan@feb ~/Downloads $ cd


Now I go looking for an executable named 'node':


dan@feb ~ $ cd .meteor
dan@feb ~/.meteor $ 
dan@feb ~/.meteor $ find . -name node -print
./packages/mongo/.1.0.11.pnwx20++os+web.browser+web.cordova/npm/node_modules/mongodb/node_modules/bson/test/node
./packages/meteor-tool/.1.0.40.1ef5dzv++os.linux.x86_64+web.browser+web.cordova/meteor-tool-os.linux.x86_64/dev_bundle/bin/node
./packages/meteor-tool/.1.0.40.1ef5dzv++os.linux.x86_64+web.browser+web.cordova/meteor-tool-os.linux.x86_64/dev_bundle/include/node
./packages/meteor-tool/.1.0.40.1ef5dzv++os.linux.x86_64+web.browser+web.cordova/meteor-tool-os.linux.x86_64/dev_bundle/lib/node_modules/cordova/node_modules/cordova-lib/node_modules/cordova-js/node_modules/browserify/node_modules/util/test/node
./packages/meteor-tool/.1.0.40.1ef5dzv++os.linux.x86_64+web.browser+web.cordova/meteor-tool-os.linux.x86_64/isopackets/mongo/npm/mongo/node_modules/mongodb/node_modules/bson/test/node
dan@feb ~/.meteor $ 


I like this node:


dan@feb ~/.meteor $ ln -s ~/.meteor/packages/meteor-tool/.1.0.40.1ef5dzv++os.linux.x86_64+web.browser+web.cordova/meteor-tool-os.linux.x86_64/dev_bundle/bin/node  .
dan@feb ~/.meteor $ cd
dan@feb ~ $ cd bin
dan@feb ~/bin $ ln -s ~/.meteor/node .
dan@feb ~/bin $ cd
dan@feb ~ $ which node
/home/dan/bin/node
dan@feb ~ $ 
dan@feb ~ $ 

Now I have node linked to ~/bin/ where my shell can find it.

Next I want a copy of npm.

I know that npm is just a script which calls npm-cli.js so I look for npm-cli.js:


dan@feb ~/.meteor $ 
dan@feb ~/.meteor $ find . -name npm-cli.js -print
./packages/meteor-tool/.1.0.40.1ef5dzv++os.linux.x86_64+web.browser+web.cordova/meteor-tool-os.linux.x86_64/dev_bundle/lib/node_modules/npm/bin/npm-cli.js
./packages/meteor-tool/.1.0.40.1ef5dzv++os.linux.x86_64+web.browser+web.cordova/meteor-tool-os.linux.x86_64/dev_bundle/lib/node_modules/cordova/node_modules/cordova-lib/node_modules/npm/bin/npm-cli.js
dan@feb ~/.meteor $ 
dan@feb ~/.meteor $ 
dan@feb ~/.meteor $ vi ~/bin/npm


I made my own npm script which is just two lines of code:

dan@feb ~ $ 
dan@feb ~ $ cd bin
dan@feb ~/bin $ 
dan@feb ~/bin $ cat npm
#!/bin/sh

basedir=~/.meteor/packages/meteor-tool/.1.0.40.1ef5dzv++os.linux.x86_64+web.browser+web.cordova/meteor-tool-os.linux.x86_64/dev_bundle/lib

node "$basedir/node_modules/npm/bin/npm-cli.js" "$@"
dan@feb ~/bin $ 
dan@feb ~/bin $ 
dan@feb ~/bin $ 


Now I test my npm script:

dan@feb ~ $ 
dan@feb ~ $ npm config list
; cli configs
registry = "https://registry.npmjs.org/"
user-agent = "npm/1.4.28 node/v0.10.33 linux x64"

; node bin location = /home/dan/bin/node
; cwd = /home/dan
; HOME = /home/dan
; 'npm config ls -l' to show all defaults.

dan@feb ~ $ 
dan@feb ~ $ 
dan@feb ~ $ 


Will my script install some random package?

dan@feb ~ $ 
dan@feb ~ $ npm install haml-coffee
haml-coffee@1.14.1 node_modules/haml-coffee
├── walkdir@0.0.7
├── coffee-script@1.9.0
└── optimist@0.6.1 (wordwrap@0.0.2, minimist@0.0.10)
dan@feb ~ $ 
dan@feb ~ $ 
dan@feb ~ $ 


I want to study my copy of node now.

dan@feb ~ $ 
dan@feb ~ $ which node
/home/dan/bin/node
dan@feb ~ $ 


What version of node do I have?

dan@feb ~ $ 
dan@feb ~ $ node -v
v0.10.33
dan@feb ~ $ 
dan@feb ~ $
