Both MDN Native Messaging example and Google Chrome extension samples had a bug in the Python implementation of the Native Messaging host.
Native Messaging host can send 1MB of data to the client (browser) per message.
The Python code was counting space characters.
Additionally, using python alone in a shell script, and not using
python3 will fail on systems that do not have python in PATH,
The application code is the same: parec -d @DEFAULT_MONITOR@ to capture 2 channel PCM output to headphones or speakers.
The values below were taken during the capture and stream to the browser.
fetch() in browser, ReadableStream, Response in server):
| [1,2,3] |
| const start = new Date(); | |
| let streams = []; | |
| let data = [...Array(1000)].map((_, i) => i); | |
| let encoder = new TextEncoder(); | |
| let resolve; | |
| let promise = new Promise((_) => (resolve = _)); | |
| let readable = new ReadableStream({ | |
| start: async (_) => { | |
| // console.log('Original stream'); | |
| return promise; |
| // https://www.reddit.com/r/learnjavascript/comments/yeodfh/chrome_extension_error_extensionsjs2897_uncaught/ | |
| // Use a Port for multiple messages | |
| chrome.runtime.onConnect.addListener((port) => { | |
| console.log(port); | |
| port.onMessage.addListener(async (message) => { | |
| if (message.name === 'stream' && message.streamId) { | |
| console.log(message.streamId); | |
| try { | |
| const stream = await navigator.mediaDevices.getUserMedia({ | |
| video: { |
Native Messaging JavaScript runtime hosts tested:
Test:
Send new Array(10000) from client to host, send message back to client, 100 times, measure time with performance.now().
