This folder contains official Yii 2 extensions.

To add a new extension named xyz (must be in lower case), take the following steps:

create a folder named xyz under yii and put all relevant source code there;
create the following accessory files (please refer to any existing extension):
- composer.json
- README.md
- CHANGELOG.md
- LICENSE.md
ask Qiang to create a subsplit for xyz and a composer package named yii2-xyz;
If an extension depends on external bower/npm packages:
- in the composer.json file of the extension, list the dependencies in the format of 'bower-asset/PackageName': '1.1';
- create an asset bundle class to list the needed js/css files from the package. The sourcePath property of the bundle should point to the distribution path of the package, such as @bower/PackageName, or @bower/PackageName/dist.
modify /composer.json and add yiisoft/yii2-xyz to the replace section. Also add any bower/npm dependencies to the require section.
