Overview

Comprehensive UI fixes and improvements across all pages, including live stream indicators, stream quality display, and Now Playing functionality.

What Was Completed

Live Stream Indicators

Fixed red/green indicator inconsistencies across all pages

Front Page

Changed 🔴 LIVE STREAM to 🟢 LIVE STREAM
Added green color styling: style"color: #00ff00;"=
Status indicator shows ● BROADCASTING in green

Web Player

Changed 🔴 Live Radio Stream to 🟢 Live Radio Stream
Consistent green indicator
Matches front page styling

Stream Quality Display

Problem Fixed

Stream quality showed "128kbps MP3" even when AAC stream was selected

Solution Implemented

Updated default to "AAC 96kbps Stereo"
Added JavaScript to sync quality display with selected stream
Quality updates dynamically when user changes streams

Implementation

function changeStreamQuality() {
  const selector = document.getElementById('stream-quality');
  const config = streamConfig[selector.value];
  
  // Update Station Status stream quality display
  const statusQuality = document.querySelector('[data-text="stream-quality"]');
  if (statusQuality) {
    statusQuality.textContent = config.format;
  }
  
  // Update stream URL and format
  document.getElementById('stream-url').textContent = config.url;
  document.getElementById('stream-format').textContent = config.format;
  
  // Update audio player
  const audioElement = document.getElementById('live-audio');
  const sourceElement = document.getElementById('audio-source');
  
  sourceElement.src = config.url;
  sourceElement.type = config.type;
  audioElement.load();
}

Page Load Initialization

window.addEventListener('DOMContentLoaded', function() {
  // Set initial quality display to match the selected stream
  const selector = document.getElementById('stream-quality');
  const config = streamConfig[selector.value];
  
  document.getElementById('stream-url').textContent = config.url;
  document.getElementById('stream-format').textContent = config.format;
  
  const statusQuality = document.querySelector('[data-text="stream-quality"]');
  if (statusQuality) {
    statusQuality.textContent = config.format;
  }
});

Now Playing Functionality

Investigation Results

No HTML rendering bug found (was a false alarm in TODO)
Now Playing working correctly on all pages
Updates every 10 seconds from Icecast
Proper text content rendering (no HTML injection)

Implementation Details

function updateNowPlaying() {
  fetch('/asteroid/api/icecast-status')
    .then(response => response.json())
    .then(data => {
      if (data.icestats && data.icestats.source) {
        const mainStream = data.icestats.source;
        
        if (mainStream.title) {
          // Parse "Artist - Track" format
          const titleParts = mainStream.title.split(' - ');
          const artist = titleParts.length > 1 ? titleParts[0] : 'Unknown Artist';
          const track = titleParts.length > 1 ? titleParts.slice(1).join(' - ') : mainStream.title;
          
          // Use textContent to prevent HTML injection
          document.querySelector('[data-text="now-playing-artist"]').textContent = artist;
          document.querySelector('[data-text="now-playing-track"]').textContent = track;
          document.querySelector('[data-text="listeners"]').textContent = mainStream.listeners || '0';
        }
      }
    })
    .catch(error => console.log('Could not fetch stream status:', error));
}

// Update every 10 seconds
updateNowPlaying();
setInterval(updateNowPlaying, 10000);

API Endpoint Fixes

Missing /api/tracks Endpoint

Created endpoint for web player to fetch tracks

(define-page api-tracks #@"/api/tracks" ()
  "Get all tracks for web player"
  (require-authentication)
  (setf (radiance:header "Content-Type") "application/json")
  (handler-case
      (let ((tracks (db:select "tracks" (db:query :all))))
        (cl-json:encode-json-to-string
         `(("status" . "success")
           ("tracks" . ,(mapcar (lambda (track)
                                  `(("id" . ,(gethash "_id" track))
                                    ("title" . ,(gethash "title" track))
                                    ("artist" . ,(gethash "artist" track))
                                    ("album" . ,(gethash "album" track))
                                    ("duration" . ,(gethash "duration" track))
                                    ("format" . ,(gethash "format" track))))
                                tracks)))))
    (error (e)
      (cl-json:encode-json-to-string
       `(("status" . "error")
         ("message" . ,(format nil "Error retrieving tracks: ~a" e)))))))

Icecast Status Endpoint

Improved XML parsing for better reliability

;; Extract title using register groups for cleaner extraction
(title (multiple-value-bind (match groups)
          (cl-ppcre:scan-to-strings "<title>(.*?)</title>" source-section)
        (if (and match (> (length groups) 0))
            (aref groups 0)
            "Unknown")))
