Base UI React Select v1.5.0 onValueChange value type official documentation

💡 Result:

In Base UI React Select v1.5.0, the value type passed to the onValueChange callback depends on whether the select is configured for single or multiple selection [1][2]. The value type follows this structure: - Single Selection: The value is of the generic type Value (provided to the Select.Root component) or null [1][2]. - Multiple Selection: The value is an array of the generic type Value[] [1][2]. Specifically, the onValueChange prop signature is defined as [1]: onValueChange?: ((value: SelectValueType<Value, Multiple> | (Multiple extends true? never: null), eventDetails: SelectRootChangeEventDetails) => void) | undefined; Where SelectValueType is defined as [2]: type SelectValueType<Value, Multiple extends boolean | undefined> = Multiple extends true? Value[]: Value; Key implementation details: 1. Nullable State: If the select is not configured with a multiple selection mode, the value can be null when an item is deselected [3]. 2. Type Inference: Base UI v1.5.0 and subsequent updates to the library improved TypeScript inference for onValueChange to ensure that the newValue parameter correctly reflects the state type (e.g., string | null or string) based on the provided generic or state [3][4]. If you are using the Select component in a controlled manner, your onValueChange handler will receive the updated value as its first argument, and an object containing event details as the second [1][2].

Citations:

Narrow the select value before updating composerSendKey.

SelectPrimitive.Root supplies string | null to onValueChange. The truthiness check removes only null, but useUpdatePrimarySettings() requires composerSendKey to be "enter" | "mod-enter". The current assignment can fail type checking.

Proposed fix 
-                if (value) {
+                if (value === "enter" || value === "mod-enter") {
                   updateSettings({ composerSendKey: value });
                 }

In `@apps/web/src/components/settings/SettingsPanels.tsx` around lines 2402 -
2404, Update the onValueChange handler for SelectPrimitive.Root near
updateSettings so it narrows the string value to the allowed composerSendKey
options, "enter" or "mod-enter", before calling updateSettings; do not rely only
on the truthiness check, and preserve ignoring null or unsupported values.
