command

自 2.27 起可用

¥Available since 2.27

创建远程命令。从浏览器调用时，该函数将通过 fetch 调用在服务器上执行。

¥Creates a remote command. When called from the browser, the function will be invoked on the server via a fetch call.

完整文档请参见远程函数。

¥See Remote functions for full documentation.

function command<Output>(
	fn: () => Output
): RemoteCommand<void, Output>;

function command<Input, Output>(
	validate: 'unchecked',
	fn: (arg: Input) => Output
): RemoteCommand<Input, Output>;

function command<Schema extends StandardSchemaV1, Output>(
	validate: Schema,
	fn: (arg: StandardSchemaV1.InferOutput<Schema>) => Output
): RemoteCommand<
	StandardSchemaV1.InferInput<Schema>,
	Output
>;

form

自 2.27 起可用

¥Available since 2.27

创建一个可展开到 <form> 元素上的表单对象。

¥Creates a form object that can be spread onto a <form> element.

完整文档请参见远程函数。

¥See Remote functions for full documentation.

function form<T>(
	fn: (data: FormData) => MaybePromise<T>
): RemoteForm<T>;

getRequestEvent

自可用以来 2.20.0

¥Available since 2.20.0

返回当前 RequestEvent。可在服务器钩子、服务器 load 函数、操作和端点（以及它们调用的函数）中使用。

¥Returns the current RequestEvent. Can be used inside server hooks, server load functions, actions, and endpoints (and functions called by them).

在没有 AsyncLocalStorage 的环境中，必须同步调用此函数（即不在 await 之后）。

¥In environments without AsyncLocalStorage, this must be called synchronously (i.e. not after an await).

function getRequestEvent(): RequestEvent<
	AppLayoutParams<'/'>,
	any
>;

prerender

自 2.27 起可用

¥Available since 2.27

创建一个远程预渲染函数。从浏览器调用时，该函数将通过 fetch 调用在服务器上执行。

完整文档请参见远程函数。

¥See Remote functions for full documentation.

function prerender<Output>(
	fn: () => MaybePromise<Output>,
	options?:
		| {
				inputs?: RemotePrerenderInputsGenerator<void>;
				dynamic?: boolean;
