Test Custom Widget Extension

When you create your custom extension to integrate with Contentstack, you can follow the steps given below to test the extension and verify if the extension is working fine before releasing it.

To test the extension, first, clone the extension repo that you have built and install the dependencies. Then, edit the HTML, CSS, and JS files from the source folder.

To install the required dependencies, run the following commands in the root folder:

npm install gulp-cli -g
npm install

To create a new build for the extension, run the following command (index.html):

gulp build

To update/test the extension while developing, run the following command:

gulp watch

Now, create a server using the Lite Server npm module. Before that, install the Lite Server module by using the following command:

npm install -g lite-server

Then, run the lite-server — in the root folder as follows:

lite-server

After running the above command, you will get the following screen:

Local_server.png


Make note of the port no in Access URLs (the localhost URL):

Next, we need to install ngrok to build secure tunnels from a public endpoint (that is the internet) to a locally running server. Issue the following command to install ngrok:

npm install ngrok -g

ngrok http <<port number>>
ngrok_hosting.png

Once you run the above command, you will get a URL. Now create an extension by navigating to your stack and selecting Settings > + Add Extension > Create new.

On the Select Extensions Type screen, select Custom Widget and then add the required details on the Create New Extension screen. 

In the Hosting method field, select External hosting and paste the above URL in it. Now save your extension and check the entry where you have added your extension.

You should see your updated changes.
