Host your client-side web part from Microsoft 365 CDN (Hello World part 4)

Microsoft 365 Content Delivery Network (CDN) provides you an easy solution to host your assets directly from your own Microsoft 365 tenant. It can be used for hosting any static assets that are used in SharePoint Online.

Note

There are multiple different hosting options for your web part assets. This tutorial concentrates on showing the Microsoft 365 CDN option, but you could also use the Azure CDN or simply host your assets from SharePoint library from your tenant. In the latter case, you would not benefit from the CDN performance improvements, but that would also work from the functionality perspective. Any location that end users can access using HTTP(S) would be technically suitable for hosting the assets for end users.

Important

This article uses the includeClientSideAssets attribute introduced in the SharePoint Framework (SPFx) v1.4. This version is not supported with SharePoint 2016 Feature Pack 2. If you're using an on-premises setup, you need to decide the CDN hosting location separately. You can also simply host the JavaScript files from a centralized library in your on-premises SharePoint to which your users have access. Please see additional considerations in the SharePoint 2016 specific guidance.

Make sure that you've completed the following tasks before you begin:

Enable CDN in your Microsoft 365 tenant

For information on enabling and configuring the Microsoft 365 CDN in your SharePoint Online tenant, see Enable the Microsoft 365 CDN.

Finalize solution for deployment

Switch to the console and make sure you're still in the project directory that you used to set up your web part project.
If you are still running the local webserver by executing gulp serve in the previous tutorial, press CTRL+C to terminate it.
Ensure you're in your project directory:
```
cd helloworld-webpart
```

Review solution settings

Open the HelloWorldWebPart web part project in Visual Studio Code or your preferred IDE.

Open package-solution.json from the config folder.

The package-solution.json file defines the package metadata as shown in the following code:

{
    "$schema": "https://developer.microsoft.com/json-schemas/spfx-build/package-solution.schema.json",
    "solution": {
        "name": "hello-world-client-side-solution",
        "id": "e8905bc9-2718-4bc8-aea6-03a2b5cf8e76",
        "version": "1.0.0.0",
        "includeClientSideAssets": true,
        "skipFeatureDeployment": true,
        "isDomainIsolated": false,
        "developer": {
            "name": "",
            "websiteUrl": "",
            "privacyUrl": "",
            "termsOfUseUrl": "",
            "mpnId": "Undefined-1.18.0"
        },
        "metadata": {
            "shortDescription": {
            "default": "HelloWorld description"
        },
        "longDescription": {
            "default": "HelloWorld description"
        },
        "screenshotPaths": [],
        "videoUrl": "",
        "categories": []
        },
    "features": [
        {
            "title": "hello-world Feature",
            "description": "The feature that activates elements of the hello-world solution.",
            "id": "45108667-812b-46ee-a8c3-7edc40b6a933",
            "version": "1.0.0.0"
        }
    ]
    },
    "paths": {
    "zippedPackage": "solution/hello-world.sppkg"
    }
}

The default value for the includeClientSideAssets is true, which means that static assets are packaged automatically in the *.sppkg files, and you don't need to separately host your assets from an external system.

Do not change this setting for this exercise, so that assets are automatically hosted when solution is deployed to your tenant.

If Microsoft 365 CDN is enabled, it's used automatically with default settings. If Microsoft 365 CDN isn't enabled, assets are served from the app catalog site collection. This means that if you leave the includeClientSideAssets setting true, your solution assets are automatically hosted in the tenant.

Prepare web part assets to deploy

Execute the following task to bundle your solution. This executes a release build of your project by using a dynamic label as the host URL for your assets. This URL is automatically updated based on your tenant CDN settings.
```
gulp bundle --ship
```
Execute the following task to package your solution. This creates an updated helloworld-webpart.sppkg package on the sharepoint/solution folder.
```
gulp package-solution --ship
```
Note

If you're interested in what actually got packaged inside of the *.sppkg file, you can look in the content of the sharepoint/solution/debug folder.
Upload or drag and drop the newly created client-side solution package to the app catalog in your tenant.
Because you already deployed the package, you're prompted as to whether to replace the existing package. Select Replace.
Notice how the domain list in the prompt says SharePoint Online. This is because the content is either served from the Microsoft 365 CDN or from the app catalog, depending on the tenant settings. Select Enable app.
Open the site where you previously installed the helloworld-webpart-client-side-solution or install the solution to a new site.
After the solution has been installed, select Add a page from the gear menu, and select HelloWorld from the modern page web part picker to add your custom web part to page.
Notice how the web part is rendered even though you're not running the local web server.
Save changes on the page with the web part.
Open your browser's development tools and open the Sources tab.
Extend publiccdn.sharepointonline.com under the source and notice how the hello-world-web-part file is loaded from the Public CDN URL pointing dynamically to a library located under the app catalog site collection.

Note

If you would not have CDN enabled in your tenant, and the includeClientSideAssets setting would be truein the package-solution.json, the loading URL for the assets would be dynamically updated and pointing directly to the ClientSideAssets folder located in the app catalog site collection. In this example case, the URL would be https://sppnp.microsoft.com/sites/apps/ClientSideAssets/. This change is automatic depending on your tenant settings and it does not require any changes in the actual solution package.

Now you've deployed your custom web part to SharePoint Online and it's being hosted automatically from the Microsoft 365 CDN.

Next steps

You can load jQuery and jQuery UI and build a jQuery Accordion web part. To continue, see Add jQueryUI Accordion to your client-side web part.
