App state

App state stores values that can be read and updated anywhere in your app.

Use it when you need to carry data between components, screens, or navigation events.

Set a value

Use the Update state action to create or change a state value.

Each state entry has:

• A key, which is the name you reference elsewhere
• A value, which can be static or bound to another source

Use app state

Once a value exists, reference it through the State binding namespace.

Common uses include:

• Passing the selected row into a form or side panel
• Storing a temporary selection while a user moves through a multi-step form
• Showing or hiding components based on a user choice

Persist a value

Enable persistence when the value should survive reloads. Budibase stores persisted state in the user's browser.

Delete a value

Delete a state value when it is no longer needed. This removes the stored value and clears any persisted copy.
