# Riffusion App
Riffusion is an app for real-time music generation with stable diffusion.

This repository contains the interactive web app that powers the website.
It is built with Next.js, React, Typescript, three.js, Tailwind, and Vercel.
## Run
This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
First, make sure you have Node v18 or greater installed using `node --version`.
Install packages:
```bash
npm install
```
Run the development server:
```bash
npm run dev
# or
yarn dev
```
Open [http://localhost:3000](http://localhost:3000) with your browser to see the app.
The app home is at `pages/index.js`. The page auto-updates as you edit the file. The about page is at `pages/about.tsx`.
The `pages/api` directory is mapped to `/api/*`. Files in this directory are treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead of React pages.
## Inference Server
To actually generate model outputs, we need a model backend that responds to inference requests via API. If you have a large GPU that can run stable diffusion in under five seconds, clone and run the instructions in the [inference server](https://github.com/hmartiro/riffusion-inference) to run the Flask app.
You will need to add a `.env.local` file in the root of this repository specifying the URL of the inference server:
```
RIFFUSION_FLASK_URL=http://127.0.0.1:3013/run_inference/
```
