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 steps.

Prerequisites

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

• Docker (for running the database and services)
• If using devcontainers
  • An IDE that supports them (VS Code with devcontainers extension, Jetbrains, etc.)
• If running directly
  • Node.js (version 20 or later)
    • 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/v0.40.1/install.sh | bash
      

  • Make (optional, for easier initial setup)

Installation

1. Follow the Prerequisites steps above
2. Clone the repository to your local machine
3. Choose one method:
   • a) Use devcontainers

     ⚠️ Important Warning for Windows Users: Either clone this repo onto a WSL volume, or use the "clone repository in named container volume" command. Otherwise, you will see performance issues.

     • Open the directory up in your IDE of choice
       • VS Code should prompt you to "Open in container"
         • If not, you may need to manually run Dev Containers: Open Folder in Container
       • For other IDEs, you may need to open the .devcontainer/devcontainer.json file, and click "Create devcontainer and mount sources"
       • Note: this may take some time to run initially
     • Run make run or npm run dev
   • b) Run make init
     • This command will do a few things:
       • Creates a starter env file
       • Installs npm packages
       • Spins up docker containers
       • Runs any additional database migrations
       • Creates some dummy seed data
       • Populates metrics and meilisearch
       • Initializes prisma
       • Runs the server
     • If you see an error about an app not being found, make sure node_modules/.bin is added to your path:
       • export PATH="$PATH:$(realpath node_modules/.bin)"
     • If you are an internal member, you can use the buzz and signals service
       • Set this up once by creating a personal access token in github (with read package permissions)
       • Set that to CR_PAT env
       • Run echo $CR_PAT | docker login ghcr.io -u USERNAME --password-stdin
   • Please report any issues with these commands to us on discord
4. Edit the .env.development file
   • Most default values are configured to work out of the box, except 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 (S3_UPLOAD_KEY and S3_UPLOAD_SECRET, S3_IMAGE_UPLOAD_KEY and S3_IMAGE_UPLOAD_SECRET).
   • Set WEBHOOK_TOKEN to a random string of your choice. This will be used to authenticate requests to the webhook endpoint.
   • Add a random string of your choice to the email properties to allow user registration
     • EMAIL_USER
     • EMAIL_PASS
     • EMAIL_FROM (Valid email format needed)
5. Run git submodule update --recursive
6. 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.

Altering your user

• First, create an account for yourself as you normally would through the UI.
• You may wish to set yourself up as a moderator. To do so:
  • Use a database editor (like DataGrip) or connect directly to the DB (PGPASSWORD=postgres psql -h localhost -p 15432 -U postgres civitai)
  • Find your user (by email or username), and change isModerator to true

Known limitations

Services that require external input will currently not work locally. These include:

• Orchestration (Generation, Training)
• Signals (Chat, Notifications, other real-time updates)
• Buzz

Data Migrations

Over the course of development, you may need to change the structure of the database. To do this:

1. Make your changes to the schema.prisma file
2. Create a folder in the prisma/migrations folder named with the convention YYYYMMDDHHmmss_brief_description_here
3. In this folder, create a file called migration.sql
4. In that file, put your sql changes
   • These are usually simple sql commands like ALTER TABLE ...
5. Run make run-migrations and make gen-prisma
6. If you are adding/changing a column or table, please try to keep the gen_seed.ts file up to date with these changes.
