I have Node/Express server set up in which several thousand audio files are stored within the src folder. I currently have a route set up that sends JSON data in the response object. I wish to also send an mp3 audio file that can be parsed at the front end and be converted to an audio object. I cannot figure out how to encode the audio file such that it may be sent. I have looked into Blobs (these don't seem to be possible in Node) and converting the binary file into a string that may be sent as part of the response body.
Any ideas as to how this may be possible?
You can directly send the audio file with something like:
res.sendFile(__dirname, "/src/audioFile.mp3");
Or you could Base64 encode the audio file for your frontend to parse:
fs.readFile("./src/audioFile.mp3", function(err, result) {
res.send(result.toString("base64"));
});
