cdnjs Library Repository
- Libraries must have notable popularity: 100 stars/watchers on GitHub, or more then 500 times download per month on npm stats are both good examples, but as long as reasonable popularity can be demonstrated the library will be added.
- Beta, release candidate and alpha releases are not usually considered ready for full production status. Requests for pre-release versions of libraries may be declined after peer review.
- We'll accept beta, release candidate and alpha releases if you are using our npm/git auto-update mechanism, if you really want it, please setup auto-update for that lib.
Please raise a new pull request for new library additions and existing library updates, following the instructions below.
- All new libraries hosted on CDNJS should have a official public repository or npm package, and the officially pre-built distribution file(s) should also be there, so that we can apply the auto-update mechanishm on that lib.
- Now CDNJS supports adding a library by a single package.json, you just need to add a valid CDNJS package.json with npm/git auto-update config, and remove its version field in package.json, then we'll handle the remaining works.
- Notes that you should have a
filenameto point to the main file of a lib, if that file is not minified, please still use
filename.min.cssstructure naming, we'll do the minify job.

Adding a new or updating an existing library
cdnjs relies on user-submitted pull requests and automatic updating via
git repository to populate and update libraries.
To add a new library, or update an existing library outside of
git, start by forking the cdnjs repo to your own GitHub account.
If you're adding/modifying outside of the GitHub browser interface, for example on the command line or with the GitHub desktop application, you will need to additionally install
node.js) locally, so that you can run the test or utils under
When you have forked the cdnjs repo, add your library to it. Libraries are stored in the
ajax/libs directory. Each library has its own subdirectory of
ajax/libs and each version of the library has its own subdirectory of the library directory name, for example:
For more information regarding this importer, please check out the repository documentation.
You should consider the following when adding to or updating the library, so that we can keep our project neat, clean and clear:
Filenames should not include a version number.
- This is OK:
useful.min.js, but this is not:
- This is OK:
If you are updating a library, please try to maintain consistency with the existing file and directory structure.
- There will be occasions, particularly with major version increments, where this is not practical.
You should sync your local repository with our master branch as new as possible, try to make the commits' parent be new.
- Please use
git pull --rebaseinstead of
git pull, use
git rebase upstream/masterinstead of
git merge upstream/master, so that we can avoid of meaningless merging.
- Please use
Only do one meaningful thing in one commits, don't mix different things into the same commit, like add two libs in a commit.
Every commits should be meaningful, don't cut one thing into multiple commits, like add a lib in 3 commits.
Inspect your work by
git statusbefore commit your change.
Inspect your commit by
git log --stat&
git log -pbefore sending a pull request.
Create or update
Each library has a corresponding
package.json, written in
npm format (see
test/schemata/npm-package.json for details or use another
package.json to crib from - it's pretty self-explanatory), and we use
filename field in
package.json to point to the mainfile of a lib, this field will be required. When an existing library is updated, the details in
package.json should be updated where required.
For example, if a new version of the library is added, the version number may need changing. Likewise, if you're adding
npm update information to a library, this is done in
npm test to check all is well
If you're updating the library outside of
npm or the GitHub browser, you should run
npm test from the library directory to ensure everything is OK.
If you run
npm test and see no errors, all is well; resolve any errors before you raise your pull request and re-run
npm test to ensure everything works.
If you see an error then run
npm install before running
vows: command not found npm ERR! Test failed. See above for more details. npm ERR! not ok code 0
Pull request pre-flight checks
- Have you complied with our conventions?
- Have you followed the library directory structure?
- Does a valid and accurate
package.jsonexist for the library?
npm testcheck out OK?
...if so, great! You're ready to raise a pull request.
Raising a pull request
Please restrict your pull request to one library. You can include >1 version/release of a library in a single pull request.
From a maintenance standpoint, it's much more straightforward to process pull requests where there is one commit for one library.
In your pull request title, tell us what you're doing.
If you are the author of the library, please add
[author]to the pull request title.
If you are adding a new lib, please add
[new]to the pull request title.
Please include the following in your pull request:
- The origin of your new files
- e.g., where you downloaded the version from
A URL is ideal. Providing the origin of your files is very helpful as the cdnjs project is peer-reviewed. Practically speaking, it also helps us process your pull request more efficiently, which means your files go live sooner. Help us and we'll help you back.
