what-song-is-this

Twitter bot to find what song is playing in a given uploaded twitter video.

How to setup.

yarn install

How to run.

• via npm script

yarn start

• via node in terminal

node --experimental-wasm-threads src/app.js

This bot makes use of the wasm ffmpeg package for converting between multimedia types. Running webassembly with threads on node js requires the experimental-wasm-threads flag when starting.

Testing

yarn test

Test files should be created with '.test.js' prefix.

How it works

• A twitter user would tag the bot under a video with @whatsongishere
• The bot running in a loop(cron job) would listen for its mentions.
• For any mention found, it checks firstly for if it has attended to this mention before. If it has, it ignores the mention
• If it hasn't attended to this mention before, it checks the DB if it has been mentioned on that song before. If it has, it uses the same response from before.
• If it hasn't been mentioned to the video before, it converts the video to the required format and makes a request to the Rapi API's shazam API to recognize it.
• Depending on the response from shazam(or whatever service integrated) it replies the at with the relevant reply.
