About the Project

Our goal with this project is to create a platform where people can share their stable diffusion models (textual inversions, hypernetworks, aesthetic gradients, VAEs, and any other crazy stuff people do to customize their AI generations), collaborate with others to improve them, and learn from each other's work. The platform allows users to create an account, upload their models, and browse models that have been shared by others. Users can also leave comments and feedback on each other's models to facilitate collaboration and knowledge sharing.

Tech Stack

We've built this project using a combination of modern web technologies, including Next.js for the frontend, TRPC for the API, and Prisma + Postgres for the database. By leveraging these tools, we've been able to create a scalable and maintainable platform that is both user-friendly and powerful.

• DB: Prisma + Postgres
• API: tRPC
• Front-end + Back-end: NextJS
• UI Kit: Mantine
• Storage: Cloudflare

Getting Started

To get a local copy up and running follow these simple example steps.

Prerequisites

First, make sure that you have the following installed on your machine:

• Node.js (version 18 or later)
• Docker (for running the database)

We recommend you have installed nvm in order to set the right node version to run this project

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.2/install.sh | bash

Installation

1. Clone the repository to your local machine.
2. Run npm install in the project directory to install the necessary dependencies.
3. Spin up required services with docker-compose up -d
   • Note: In addition to postgres and redis, this will also run maildev for email and minio for s3 storage with all necessary buckets automatically created, minio and maildev are not strictly needed but are preferred for testing and development purposes.
4. Create your .env by making a copy of the contents from .env-example file.
   • Most default values are configured to work with the docker-compose setup, with the exception of the S3 upload key and secret. To generate those, navigate to the minio web interface at http://localhost:9000 with the default username and password minioadmin, and then navigate to the "Access Keys" tab. Click "Create Access Key" and copy the generated key and secret into the .env file.
   • Set WEBHOOK_TOKEN to a random string of your choice. This will be used to authenticate requests to the webhook endpoint.
5. Run npm run db:migrate to run all database migrations.
6. Run npm run db:generate to generate the prisma client.
7. Start the development server by running npm run dev.
8. Visit the page http://localhost:3000/api/webhooks/run-jobs?token=WEBHOOK_TOKEN&run=update-metrics to start the metrics update job (make sure to substitute WEBHOOK_TOKEN)
9. Finally, visit http://localhost:3000 to see the website.
   • Note that account creation will run emails through maildev, which can be accessed at http://localhost:1080.
   • Also note that Cloudflare credentials are necessary in order for image uploads to work.

Important Scripts
