Parse, manipulate, and display dates.
There are a few things being deprecated in the 1.6.0 release.
The format tokens
zz (timezone abbreviations like EST CST MST etc) will no longer be supported. Due to inconsistent browser support, we are unable to consistently produce this value. See this issue for more background.
moment.fn.native is deprecated in favor of
moment.fn.toDate. There continue to be issues with Google Closure Compiler throwing errors when using
native, even in valid instances.
The way to customize am/pm strings is being changed. This would only affect you if you created a custom language file. For more information, see this issue.
To contribute, fork the library and install these npm packages.
npm install jshint uglify-js nodeunit
You can add tests to the files in
/test/moment or add a new test file if you are adding a new feature.
To run the tests, do
make test to run all tests,
make test-moment to test the core library, and
make test-lang to test all the languages.
To check the filesize, you can use
To minify all the files, use
make moment to minify moment,
make langs to minify all the lang files, or just
make to minfy everything.
If your code passes the unit tests (including the ones you wrote), submit a pull request.
Moment.js now uses git-flow. If you're not familiar with git-flow, please read up on it, you'll be glad you did.
When submitting new features, please create a new feature branch using
git flow feature start <name> and submit the pull request to the
Pull requests for enhancements for features should be submitted to the
develop branch as well.
When submitting a bugfix, please check if there is an existing bugfix branch. If the latest stable version is
1.5.0, the bugfix branch would be
hotfix/1.5.1. All pull requests for bug fixes should be on a
hotfix branch, unless the bug fix depends on a new feature.
master branch should always have the latest stable version. When bugfix or minor releases are needed, the develop/hotfix branch will be merged into master and released.
