Develop & Test

When building xApps, there are some tools to make building & sharing your xApp easier.

While developing your xApp, you may want to easily test & debug your web application. You may even benefit from live reaload during development. You can expose your local development environment with a tool like https://ngrok.io or https://localtunnel.me and configure your public URL as your xApp URL.

You can get access to the remote browser console using the techniques explained in the Development & Debugging article.

If you want to share your xApp with a small group of testers or team members, you can ask them for their Xumm Device Identifier (Xumm - Settings - Advanced). You can add up to 10 Device Identifiers as xApp testers, so they can open your sandboxed xApp.

Warning! If you have multiple xApps (e.g. a live version & a test version, pointing to your development URL) please make sure to use the right API Key, otherwise your app can't communicate with the Xumm backend. Also note things like https://github.com/XRPL-Labs/Developer-Help-Center/blob/main/js-ts-sdk/sdk-syntax/xumm.userstore are API Key & user bound.

When you want to develop in your local browser instead of in Xumm, please see the "OTT Replay" section in the Development & Debugging article.

We are currently working on a Desktop xApp Development Application so you can develop & test locally 🎉 (Work in progress, more good things are coming)
