What have we done in cdnjs in last year (2015)?

Merry Christmas and Happy New Year!

Thanks all the users, developers and the contributors! We did a lot of things in 2015, though there are still many issues that waiting to be solved, we’ll keep working on it, at the end of year 2015 and the beginning of year 2016, let’s have a fast review of the changes and rising in cdnjs during 2015!


  • We now got more than 3.3k stars and about 2.5k forks on GitHub
  • We had 9339 commits in the beginning of 2014, became more than 10k commits since Feburary, and now about 18200 commits
    • 8892 commits were committed in last year!
  • We have more than 1000 contributors in 2015! (Sorry that I don’t remember the contributors count at the beginning of last year)
  • We had only 1220 libraries hosted on cdnjs, but 1669 libraries been hosted now!
    • 449 new libraries added in 2015!

(PS: Above data only calculated the cdnjs main repository, we have some other repos here)


Use ‘nvm’ to manage/install nodejs with multiple versions!

NVM stands for Node Version Manager, just like its name, it’ll help us manage nodejs environment in a easy way.

NVM didn’t support Windows officially, but on Mac and Linux.

If you want to compile nodejs from sure(not requried), you should have c++ compiler, on Ubuntu(I’m using Ubuntu 14.01.2 LTS), try:
$ sudo apt-get install libssl-dev build-essential

Use the install script to install nvm is the easiest way(should have bash, if not, try manual install):
$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.25.3/install.sh | bash

NVM will be installed in few seconds:

% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed

=> Downloading nvm as script to ‘/home/peter/.nvm’

=> Appending source string to /home/peter/.bashrc
=> You currently have modules installed globally with `npm`. These will no
=> longer be linked to the active version of Node when you install a new node
=> with `nvm`; and they may (depending on how you construct your `$PATH`)
=> override the binaries of modules installed with `nvm`:

=> If you wish to uninstall them at a later point (or re-install them under your
=> `nvm` Nodes), you can remove them from the system Node as follows:

$ nvm use system
$ npm uninstall -g a_module

=> Close and reopen your terminal to start using nvm

That’s all … should reload your shell’s rc file or re-login, and try nvm now:

How to use a specified version of nodejs?

Install it by nvm(for the first time, add parameter -s if you want to install from source):
$ nvm install 0.11

Should be done in few secs:

######################################################################## 100.0%
Now using node v0.11.16 (npm v2.3.0)

And you can use nvm use to change to the version you want, like this:
$ nvm use 0.12

Now using node v0.12.3 (npm v2.9.1)

How to know current nodejs versions?
$ nvm current


How to list installed nodejs versions?
$ nvm ls

-> v0.10.38

How to list the nodejs versions available?
$ nvm ls-remote
It’ll give a very long version list like above but longer and longer ….

run nvm without parameter will print you the usage, very easy to understand like this:
