Troubleshooting
This section describes common troubleshooting technics to debug and improve your apps.
If you're experiencing performance issues or encountering the "Constant re-renders detected" message, this could point to a cyclic dependency in your app or other performance-related issues:
- Use of
Math.random()ornew Date().getTime()in computed component properties: Such declarations generate a new unique value every time UI Bakery re-renders the page. As a result, components produce new state values in component variables like{{ui.input.value}}, which subsequently triggers another re-render. It's advisable to avoid such declarations. - Cyclic dependencies in component configurations: For example, you might have two input components where each input references the value of the other input (i.e.,
{{ui.input.value}}) as its Value property. This setup can lead to continuous re-renders and may significantly impede the app's performance. - Infinite cycles in action code: Check for loops like
while(true)that might continuously produce new values, leading to persistent re-renders. - Improper use of UI Bakery state variables: Utilizing broad scopes, such as
{{state}}or{{actions}}in component properties, can prompt UI Bakery to continuously update the page, ensuring it reflects the most recent values. It's recommended to modify these references to point to precise values, like{{state.variableName}}.
