This commit introduces the ability to handle log files through the API and provides a new log viewing page. The API now supports GET and DELETE methods for log file operations, allowing retrieval and deletion of log contents. A new log.html page has been added for viewing logs in the browser, with automatic refresh every 5 seconds and styling based on log levels. The app.go file has been updated to include a GetLogFilepath function that retrieves or generates the log file path. The NewLogger function now accepts a file parameter to enable file logging. The main.js file has been updated to include a link to the new log.html page. This enhancement improves the observability and management of the application by providing real-time access to logs and the ability to clear them directly from the web interface.
Browser support
ECMAScript 2019 (ES10) supported by iOS 12 (iPhone 5S, iPad Air, iPad Mini 2, etc.).
But ECMAScript 2017 (ES8) almost fine (es6 + async) and recommended for React+TypeScript.
Known problems
- Autoplay doesn't work for WebRTC in Safari read more.
HTML5
1. Autoplay video tag
Video auto play is not working
Recently many browsers can only autoplay the videos with sound off, so you'll need to add muted attribute to the video tag too
<video id="video" autoplay controls playsinline muted></video>
2. [Safari] pc.createOffer
Don't work in Desktop Safari:
pc.createOffer({offerToReceiveAudio: true, offerToReceiveVideo: true})
Should be replaced with:
pc.addTransceiver('video', {direction: 'recvonly'});
pc.addTransceiver('audio', {direction: 'recvonly'});
pc.createOffer();
3. pc.ontrack
TODO
pc.ontrack = ev => {
const video = document.getElementById('video');
// when audio track not exist in Chrome
if (ev.streams.length === 0) return;
// when audio track not exist in Firefox
if (ev.streams[0].id[0] === '{') return;
// when stream already init
if (video.srcObject !== null) return;
video.srcObject = ev.streams[0];
}
Chromecast 1
2023-02-02. Error:
InvalidStateError: Failed to execute 'addTransceiver' on 'RTCPeerConnection': This operation is only supported in 'unified-plan'. 'unified-plan' will become the default behavior in the future, but it is currently experimental. To try it out, construct the RTCPeerConnection with sdpSemantics:'unified-plan' present in the RTCConfiguration argument.
