This is Part 5 of our SDK development series where we get a CDN of our SDK

## Contents:

* ⚡ `Getting CDN`
    
* ⚡ `Integrating CDN and testing SDK`
    

### Step 1: Get a CDN

Head over to [`https://www.jsdelivr.com/`](https://www.jsdelivr.com/) and search for your NPM package.

Choose the default version, and copy the link.

Head over to the Test Browser app, and integrate the CDN:

```xml
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Document</title>
    <script src="https://cdn.jsdelivr.net/npm/ts-lib-template-starter@1.0.0/dist/index.global.min.js"></script>
  </head>
  <body>
    This is a Test HTML

    <script>
      sdk.fetchUsers().then((users) => console.log(users));
    </script>
  </body>
</html>
```

Open the file, and see the result:

### Step 2: Getting the latest CDN version always

Put `@latest` instead of the version to always fetch the latest CDN version

`https://cdn.jsdelivr.net/npm/ts-lib-template-starter@latest/dist/index.global.min.js`

Sometimes, when a new version of SDK is published, `jsDeliver` few minutes to a few days to point `@latest` version to the updated version.

To fix this, when you publish a new version, head over to [`https://www.jsdelivr.com/tools/purge`](https://www.jsdelivr.com/tools/purge) and enter the link of the CDN like:

This will purge the cache and point `@latest` version to the updated version.

## Wrapping Up:

We Just completed the steps to get a CDN of our SDK.

Stay tuned for further parts to dive deep into SDK development and explore features like Web Push Notifications, Service Workers etc. 🚀

.....

Now you're equipped with the knowledge to publish your own SDK. Happy coding! 🚀

That's it, folks! hope it was a good read for you. Thank you! ✨
