🧪 Testing Mini-Apps Locally

To test Mini-Apps in action on Universal Everything, we need to expose our Mini-App to an URL that can be accessed by the UP Provider.

We will be using localtunnel for this purpose.

Install localtunnel

Install localtunnel globally to access it from any directory.

npm install -g localtunnel

Run localtunnel

In a new terminal window, run the following command:

lt --port <PORT> // localhost port that your Mini-App is running on (e.g. 3000)

Running the command will generate a random URL. Initial visit to this URL will ask for a password, you can use your IP address to access your Mini-App.

info

If you don't have your IP address in hand, you can visit the URL on the page to retrieve it.

Test your Mini-App on Universal Everything

Go to your Universal Profile on Universal Everything, and add your Mini-App with using the provided URL to your Grid.
