SafeClientOpts​

Type of options when creating a new safe action client.

export type SafeClientOpts<Context> = {
  handleServerErrorLog?: (e: Error) => MaybePromise<void>;
  handleReturnedServerError?: (e: Error) => MaybePromise<string>;
  middleware?: (parsedInput: unknown) => MaybePromise<Context>;
};

SafeAction​

Type of the function called from Client Components with typesafe input data.

type SafeAction<S extends Schema, Data> = (input: InferIn<S>) => Promise<{
  data?: Data;
  serverError?: string;
  validationErrors?: Partial<Record<keyof Infer<S> | "_root", string[]>>;
}>;

ServerCodeFn​

Type of the function that executes server code when defining a new safe action.

type ServerCodeFn<S extends Schema, Data, Context> = (
  parsedInput: Infer<S>,
  ctx: Context
) => Promise<Data>;

/hooks​

HookResult​

Type of result object returned by useAction and useOptimisticAction hooks.

If a server-client communication error occurs, fetchError will be set to the error message.

type HookResult<S extends Schema, Data> = Awaited<ReturnType<SafeAction<S, Data>>> & {
  fetchError?: string;
};

HookCallbacks​

Type of hooks callbacks. These are executed when action is in a specific state.

type HookCallbacks<S extends Schema, Data> = {
  onExecute?: (input: InferIn<S>) => MaybePromise<void>;
  onSuccess?: (data: Data, input: InferIn<S>, reset: () => void) => MaybePromise<void>;
  onError?: (
    error: Omit<HookResult<S, Data>, "data">,
    input: InferIn<S>,
    reset: () => void
  ) => MaybePromise<void>;
  onSettled?: (
    result: HookResult<S, Data>,
    input: InferIn<S>,
    reset: () => void
  ) => MaybePromise<void>;
};

HookActionStatus​

Type of the action status returned by useAction and useOptimisticAction hooks.

type HookActionStatus = "idle" | "executing" | "hasSucceeded" | "hasErrored";

TypeSchema library​

Infer, InferIn, Schema types come from TypeSchema library.
