I have what I believe is a valid JSONRPC response, but the above error gets thrown,
const response = await remote.call(
"sys.versions",
{},
{
jwt: "...",
}
);
JSON response:
{"jsonrpc":"2.0","result":{"boost":{"version":"1.80.0"},"libtorrent":{"revision":"63e1ec8c8","version":"2.0.8.0"},"nlohmann_json":{"version":"3.11.2"},"openssl":{"release_date":"1 Nov 2022","version":"3.0.7","version_text":"OpenSSL 3.0.7 1 Nov 2022"},"porla":{"branch":"-","commitish":"-","version":"0.30.0"},"sqlite":{"source_id":"2022-11-16 12:10:08 89c459e766ea7e9165d0beeb124708b955a4950d0f4792f457465d71b158d318","version":"3.40.0"},"tomlplusplus":{"version":"3.1.0"}}}
Any help would be much appreciated.
New std/http API uses native HTTP and is very different from previous std/http
would be cool to support it
I'll submit a PR for this
With Firefox (89.0) I'm getting the following error message:
Uncaught SyntaxError: private fields are not currently supported
Importing the js file created with deno bundle "https://deno.land/x/[email protected]/mod.ts"
Do you have plans to add websocket support to your library?
Currently generateId() function called when creating remote is relying on window object to be available
https://github.com/timonson/gentle_rpc/blob/master/client/creation.ts#L5
IMO this is not correct, because there is no window when you launch deno worker. This means that library can't be used inside deno workers.
Consider following server:
// rpcParent.ts
import {serve} from "https://deno.land/[email protected]/http/server.ts";
import { respond } from "https://deno.land/x/gentle_rpc/mod.ts";
const worker = new Worker(new URL("./rpcC.ts", import.meta.url).href, { type: "module" });
worker.postMessage("hello");
const rpcMethods = {
bye: (name: string) => {
console.log("bye", name);
return "bye" + name;
},
}
serve((req) => respond(rpcMethods, req), { port:9010 });
and finally a worker implementation
// file: rpcC.ts
import { createRemote } from "https://deno.land/x/gentle_rpc/mod.ts";
self.onmessage = async (e) => {
const remote = await createRemote(new WebSocket("ws://0.0.0.0:9010"));
const something = await remote.call("bye", ["arg1"])
console.log(something)
remote.socket.close()
}
now if you launch parent file it will create a worker, post message, worker will try to create a remote, and it will crash with following
> deno run --allow-net --allow-read --allow-write --unstable --no-prompt tmp/rpcParent.ts
Listening on http://localhost:9010/
error: Uncaught (in worker "") (in promise) ReferenceError: window is not defined
return window.crypto.getRandomValues(new Uint32Array(1))[0].toString(16);

Hi!
Thank you for an excellent library first!
Now I'm trying to use the lib and found a few corner cases I would like to point out:
router
.post("JSONRPC", "/rpc", async (ctx) => {
const req = {
headers: ctx.request.headers,
async text() {
return await (ctx.request.body({ type: "text" }).value).catch(() => "")
},
}
const res = await respond(rpcMethods, req as Request, {
additionalArguments: [{ args: { _ctx: ctx.state }, allMethods: true }],
// publicErrorStack: true,
})
ctx.response.status = res.status
res.headers.forEach((value, key) => ctx.response.headers.set(key, value))
ctx.response.body = res.body
})
try { console.log(await remote.batch({ nonExisting1: ["nonExisting1"], existing: ["existing"] })) } catch (e) { console.error({ m: e.message, c: e.code, d: e.data, i: e.id }) }
What do you think? Feasible to be fixed in library or should be left to app level?
TIA
I am considering implementing valita for the validation of the arguments, especially on the server side. What do you guys think about this idea?
I have an Elgato WaveLink microphone, and the user-space software for that exposes a JSON-RPC interface to control the microphone. Using the following code, I can connect and attempt to issue a command against the software. The handler I directly register on the socket will log the message coming back just fine, but the await
ed call never resolves. Any idea what could be causing this?
❯ deno --version
deno 1.8.1 (release, x86_64-pc-windows-msvc)
v8 9.0.257.3
typescript 4.2.2
import { createRemote } from './deps.ts';
console.log('Opening connection...');
const socket = new WebSocket('ws://127.0.0.1:1824');
socket.addEventListener('open', () => console.log('connection open'));
socket.addEventListener('message', message => console.debug(message)); // This will successfully log out the response
socket.addEventListener('error', error => console.error(error));
socket.addEventListener('close', () => console.log('connection closed'));
const remote = await createRemote(socket);
const appInfo = await remote.getApplicationInfo(); // This never resolves
console.log('Got app info:')
console.debug(appInfo);
