// Bun Native Messaging host // guest271314, 10-9-2022 async function getMessage() { const { promise, resolve } = Promise.withResolvers(); // https://github.com/simov/native-messaging/blob/8e99d2a345ae94426a502d05aa5d57b966f6bc78/protocol.js let messageLength = 0, bytesWritten = 0, input = [];

Does not send messages from host to browser equal or to 65536 length.

In Node.js this code https://github.com/simov/native-messaging/blob/master/protocol.js does this

Yes. You can utilize Native Messaging. See https://github.com/simov/native-messaging.

// Node.js Native Messaging host // https://github.com/simov/native-messaging/blob/master/protocol.js // https://github.com/simov/native-messaging/blob/master/nodejs/example.js // Might be good to use an explicit path to node on the shebang line // in case it isn't in PATH when launched by Chrome process.stdin.on('readable', () => { let input = []; let chunk; while ((chunk = process.stdin.read())) { input.push(chunk); } input = Buffer.concat(input); const msgLen = input.readUInt32LE(0); const dataLen = msgLen + 4; if (input.length >= dataLen) { const content = input.slice(4, dataLen); const json = JSON.parse(content.toString()); handleMessage(json); } });

And/or control node and any other programming language from the browser using Native Messaging native-messaging-nodejs.

We can process asynchronous tasks without blocking reading stdin (e.g., full-duplex).

WHat do you mean by "contribute"? I download only the node executable using download-node-nightly-executable to run native-messaging-nodejs, servers, or whatever else I decide to experiement on - without downloading any packages.

I re-wrote the original code substituting using readSync for process.stdin.on('readable', () => {}) and including process.stdout._handle.setBlocking(true) and readFullSync function contributed by a Deno user https://github.com/guest271314/native-messaging-nodejs/blob/main/nm_nodejs.mjs. I wanted to a) get the input message (up to 1MB at a time) echo'ed back to the client; and b) get away from using process.stdin.on('readable', () => {}), rather use an approach that did not include event listeners; c) get away from using CommonJS and package.json and instead use Ecmascript modules without package.json.

If you want you can use a Node.js Native Messaging host https://github.com/guest271314/native-messaging-nodejs, Deno, QuickJS, txiki.js, Bun, C, C++, Python, WASI/WebAssembly or whatever language is built in, e.g., Bash.

I just fetch the nightly node executable, get rid of everything else in the archive, use .mjs extension for import to work without package.json, then I can connect to the host https://github.com/guest271314/native-messaging-nodejs, and start subprocesses, e.g., raw PCM streams, where stdout is streamed to the client (browser), e.g, https://github.com/guest271314/captureSystemAudio/blob/master/native_messaging/capture_system_audio/capture_system_audio_node.js.

Yes, utilizing Native Messaging https://github.com/guest271314/native-messaging-nodejs.
