Hi @terrence. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Hmm, I don't know enough to give you a confident answer yet. The knowledge sources provided do not contain information about handling audio data with Wasp or dealing with Superjson specifically. I would recommend checking the Wasp documentation or reaching out to the Wasp community for more specific guidance on this issue. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @terrence, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist: Perhaps try again in 15mins?

Actions and queries are made to work with JSON data, to get raw audio, either save the audio in some object storage e.g. S3, R2 and then use that link on the frontend. Or create a custom API which can return an audio file response instead of JSON 🙂 https://wasp-lang.dev/docs/advanced/apis#defining-the-apis-nodejs-implementation @kapa.ai how to return an audio file in Express instead of JSON

Custom HTTP API Endpoints | Wasp

In Wasp, the default client-server interaction mechanism is through Operations. However, if you need a specific URL method/path, or a specific response, Operations may not be suitable for you. For these cases, you can use an api. Best of all, they should look and feel very familiar.

Let me check the knowledge base for you. One moment! :books: ---------------------- To return an audio file in Express instead of JSON, you can use the res.sendFile() function. This function sets the appropriate headers to instruct the browser to download the file or display it if it can (like in the case of audio or image files). Here is a basic example:

app.get('/your-audio-endpoint', function(req, res){
  const file = `${__dirname}/path-to-your-audio-file.mp3`;
  res.sendFile(file); // Set disposition and send it.
});

app.get('/your-audio-endpoint', function(req, res){
  const file = `${__dirname}/path-to-your-audio-file.mp3`;
  res.sendFile(file); // Set disposition and send it.
});

In this example, replace 'your-audio-endpoint' with the path you want to use for your endpoint, and replace 'path-to-your-audio-file.mp3' with the actual path to your audio file. Please note that this is a general Express.js solution. To integrate it with Wasp, you might need to use the serverSetup function as mentioned in this Discord thread (https://discord.com/channels/686873244791210014/1210568665347526757). However, the knowledge sources provided do not contain a specific example of serving files with Wasp and Express.js. For more information on serving static files in Express.js, you can refer to the Express.js documentation (https://expressjs.com/en/starter/static-files.html). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @miho, I seem to be having a bit of trouble.
