It helps resolve dependencies and get lists of files ready for generating HTML `` and `` tags. Requirements ------------ [](#requirements) - PHP 8.1 - 8.5. - `mbstring` PHP extension. Installation ------------ [](#installation) The package could be installed with [Composer](https://getcomposer.org): ``` composer require yiisoft/assets ``` General usage ------------- [](#general-usage) There are three main steps using the package: 1. [Define asset bundles](docs/guide/en/asset-bundles.md). These are config classes defining where your assets are and how they should be used. 2. [Register bundles to asset manager](docs/guide/en/asset-manager.md) and obtain list of files to include. 3. Optionally [use asset converter with asset bundle](docs/guide/en/asset-converter.md) for asset format conversion (such as TypeScript to JavaScript). 4. Use your favorite method to include files into HTML (out of scope of this package).
