Currently, cdnjs's repo is too huge and some people have issues with using it when it is this big. To get around the issue or repo size you can use sparse-checkout. It lets you check out only the files you want, so that the whole directory in your computer won't need to be 11GB, but only about 1GB (you can make this even smaller with shallow pull too!)
Here are the steps:
1.Create/Initial a empty repo and enter it:
$ git init cdnjs && cd cdnjs
Initialized empty Git repository in /home/peter/.git/
2.Enable sparseCheckout:
$ git config core.sparseCheckout true
3.Set what you want to checkout only, write to .git/info/sparse-checkout, one line for one rule, for example, the jquery lib:
$ echo '/ajax/libs/jquery/*' >> .git/info/sparse-checkout
Here is an example of .git/info/sparse-checkout:
/build
/test
/tools
/scratch
/MIT-LICENSE
/hooks
/*.yml
/*.md
/*.json
/*.sh
/*.js
/ajax/libs/jquery/*
#/ajax/libs/*/package.json // for tools/createSparseCheckoutConfig.js
You can update your .git/info/sparse-checkout and then do git reset --hard to update the working directory to be the same as you configured.
4.Set your remote, for example:
$ git remote add origin git://github.com/cdnjs/cdnjs.git
If you already cloned a cdnjs repo, this time, you can set a local path to speed up, for example:
$ git remote add origin ///home/peter/cdnjs.old
5.Pull things into your new repo with shallow pull, for example, set depth to 10:
$ git pull origin master --depth 10
It's all done, you will only have jquery lib now and other files won't be checked out. Let's take a look at the space it used:
$ du -d 1 -h
18M ./ajax
587M ./.git
605M .
The database behind git is only 587MB, and the whole repo is only 605MB, awesome!
What's the origin one?
$ du -d 1 -h
682M ./.git
43M ./scratch
16M ./node_modules
12G ./ajax
24K ./test
32K ./build
13G .
The crazy 13GB/682MB haha ...
This tip can also avoid sortable/Sortable issue(#3650) in case-insensitive filesystem, especially Mac OS.
Hope you like it!
