yii2asset uses cdn

Using CDN acceleration resources in Yii2 can: register a CDN service and set CDN zones and cache rules in it. Configure CDN in the Yii2 configuration file: Add a CDN URL, enable link assets, specify the package to be accelerated. For example, when using a Bootstrap asset, its CDN can be configured as '//cdn.example.com/yii2-assets/'. Make sure that the CSS and JS files are configured with high cache expiration time to quickly serve from the CDN.

Use CDN to accelerate resources in Yii2

What is CDN?

CDN (Content Distribution Network) is a distributed server network designed to provide content to end users at the fastest speed. It reduces latency and improves response time by storing content closer to the user.

Using CDN in Yii2

The Yii2 framework provides a mechanism to easily accelerate your assets (CSS, JS, images) using CDN.

step:

1. Register a CDN service: Select a CDN provider and register an account.
2. Configuring CDN: Set up CDN zones and cache rules in the CDN provider's dashboard.
3. Configure Yii2: Add the following code to the Yii2 configuration file:

<code class="php">'components' => [ 'assetManager' => [ 'linkAssets' => true, 'bundles' => [ // 'yii\bootstrap\BootstrapAsset' => [ // 'baseUrl' => '//cdn.example.com/yii2-assets/', // ], ], ], ],</code>

4. Replace base URL: Replace baseUrl with CDN URL.
5. Enable link assets: Set linkAssets to true .
6. Specify the package to accelerate: Specify the package to accelerate and its CDN URL in bundles array.

Example:

Using Bootstrap assets, you can configure the CDN to:

<code class="php">'components' => [ 'assetManager' => [ 'linkAssets' => true, 'bundles' => [ 'yii\bootstrap\BootstrapAsset' => [ 'baseUrl' => '//cdn.example.com/yii2-assets/', ], ], ], ],</code>

When configuring CDN zones and cache rules, make sure that the CSS and JS files are configured with high cache expiration time so that they are provided directly from the CDN when the user returns to your site.
