|

|

|
||
*
|
||
* ```ts
|
||
* Deno.serve((_req) => new Response("Hello, world"));
|
||
* ```
|
||
*
|
||
* You can change the address to listen on using the `hostname` and `port`
|
||
* options. The below example serves on port 3000.
|
||
*
|
||
* ```ts
|
||
* Deno.serve({ port: 3000 }, (_req) => new Response("Hello, world"));
|
||
* ```
|
||
*
|
||
* You can stop the server with an AbortSignal. The abort signal needs to be
|
||
* passed as the `signal` option in the options bag. The server aborts when
|
||
* the abort signal is aborted. To wait for the server to close, await the
|
||
* promise returned from the `Deno.serve` API.
|
||
*
|
||
* ```ts
|
||
* const ac = new AbortController();
|
||
*
|
||
* Deno.serve({ signal: ac.signal }, (_req) => new Response("Hello, world"))
|
||
* .then(() => console.log("Server closed"));
|
||
*
|
||
* console.log("Closing server...");
|
||
* ac.abort();
|
||
* ```
|
||
*
|
||
* By default `Deno.serve` prints the message `Listening on http://<hostname>:<port>/`
|
||
* on start up. If you like to change this behaviour, you can specify a custom
|
||
* `onListen` callback.
|
||
*
|
||
* ```ts
|
||
* Deno.serve({
|
||
* onListen({ port, hostname }) {
|
||
* console.log(`Server started at http://${hostname}:${port}`);
|
||
* // ... more info specific to your server ..
|
||
* },
|
||
* handler: (_req) => new Response("Hello, world"),
|
||
* });
|
||
* ```
|
||
*
|
||
* To enable TLS you must specify the `key` and `cert` options.
|
||
*
|
||
* ```ts
|
||
* const cert = "-----BEGIN CERTIFICATE-----\n...\n-----END CERTIFICATE-----\n";
|
||
* const key = "-----BEGIN PRIVATE KEY-----\n...\n-----END PRIVATE KEY-----\n";
|
