This folder contains official Yii 2 extensions.

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

1. create a folder named xyz under yii and put all relevant source code there;
2. create the following accessory files (please refer to any existing extension):
   • composer.json
   • README.md
   • CHANGELOG.md
   • LICENSE.md
3. ask Qiang to create a subsplit for xyz and a composer package named yii2-xyz;
4. 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.
5. modify /composer.json and add yiisoft/yii2-xyz to the replace section. Also add any bower/npm dependencies to the require section.
