Save Instance Widget for Experience Builder

The Save Instance Widget lets you save and share the current state of your web map in Experience Builder — including extent, visible layers, basemap, graphics, and more. It's inspired by the classic Save Session Widget from Web AppBuilder, but built specifically for ArcGIS Experience Builder.

🛠 Installation

You can download the latest compiled version of the Save Instance Widget from JensenGIS.

⚙️ Setup

Once downloaded, follow Esri’s guide on how to add custom widgets to your Experience Builder installation.

1. Place the widget inside your /widgets directory.
2. In Experience Builder, go to the Insert Widget tab and scroll down to the Custom Widgets section.
3. Drag the Save Instance Widget onto your toolbar.
4. Configure the widget by selecting a map for it to interact with.

That’s it — you’re ready to go.

🚀 Usage

💾 Save an Instance

Enter a name for the instance and click the Save Instance button.

🔄 Load an Instance

Click the Load Instance button to apply a previously saved map state.

✏️ Rename an Instance

Click the Edit Instance Name button and enter a new name when prompted.

📥 Download an Instance

Click Download Instance to export a .txt file containing that instance.

You can also download all saved instances using the Download Instances button at the bottom right of the widget.

🧹 Clear Instance Graphics

Click Clear Instance Graphics to remove any graphics associated with the instance from the map.

I'd love to get instance-loaded graphics working with the Esri Draw Widget at some point. It’ll take a bit of setup, but if it’s something people are asking for, I’m happy to start looking into it — just let me know!

🗑️ Delete an Instance

Click Delete Instance to permanently remove it from your saved list.

🔗 Sharing Instances

To share a saved instance, simply send the .txt file to another user. They can import it using the Upload Instances button in the bottom-left corner of the widget.

In the future, I’d love to add support for cloud storage of instances — let me know if that’s something you’d use!

I’m also happy to hear requests for:

• Migrating existing Web AppBuilder widgets to Experience Builder
