- This week, in collaboration with Matt I rebuilt the Web App and Queue Manager backend module for processing User requests and storing the collaborative song queue. Now, the songs and the song queue are stored in local memory by the backend process, and the queue state is forwarded to each User’s app client via their web socket connection. When a New User logs onto the app they can enter a Username to be displayed next to their song requests, and they are immediately sent a JSON payload containing the current queue. Users can send a new song request to the server through a form, and it will appear immediately on the next slot in the queue on all Users’ app views simultaneously. I also polished the frontend side of the app for better readability and queue consistency among distributed instances of the web app.
This new Java backend (and tweaked frontend for cleaner queue display) will cooperate nicely with our Spotify semantic match and bluetooth ‘Play’ functionality, as each successive song can be popped off the queue and their song details can be used to find a match and be played from the Spotify song database. The Song datastructure managed by the queue hosted on the backend will contain all the information necessary to generate a query to the Spotify Web API. - Our group is making very good progress on schedule. This week were able to implement much of the fundamental functionality of the project, and now every major component of our project (besides the lighting, as the lighting fixtures we ordered just arrived at the end of this week) is well fleshed out.
- In the upcoming week we hope to finish or make significant progress in integrating our modules together. More specifically, we want our Web App backend to be able to communicate which songs are on the queue to our Spotify Web API facing Player modules to actually play them on the speaker. Additionally, we will do a quick sanity check on the lighting fixture to make sure the DmxPy library is capable of controlling the lighting off the Raspberry Pi, and perhaps begin writing a few of the color scheme scripts we will be running on it.
