# SaaS template

This is not gonna make You rich, but it sure as hell will save you a lot of time!

This is production ready setup for Convex and Next SaaS.

## Features

- Auth
- Stripe
- shadcn/create UI templte
- next intl
- next themes
- Backend/Frontend Tests
- Tmuxinator
- CICD
- accurate instructions

## Development process

### Environments

- Dev cloud environment - based on `develop` branch
- Prod cloud environment - based on `main` branch

## Getting Started

First, run the development server:

```bash
pnpm dev --webpack
```

> [!NOTE]
> As of Next.js@16.2.1  turbopack is broken ant it spikes CPU usage by 900% and 8-9GiB of RAM usage, thus why we use webpack. Wait for 16.3.0 to migrate to turbopack

### Convex

[Source of truth](https://github.com/get-convex/convex-backend/blob/main/self-hosted/README.md)

1. Go on Coolify, search for Convex and set it up.

> [!IMPORTANT]
> Best case: [copy config from here](https://github.com/get-convex/convex-backend/blob/main/self-hosted/docker/docker-compose.yml), paste it instead of Coolify's docker-compose file, then go into environment variables, copy them, paste them and the new docker-compose into an AI agent and tell him to properly map the envs to docker-compose so it's ready to deploy on coolify.

This works for Convex 1.34.0 (CLI+backend/dashboard)

    depends_on:
      backend:
        condition: service_healthy
volumes:

```

Then make sure to update domains and env vars accordingly

2. Deploy the service(s - dashboard and the db). It has built-in persistent storage
3. Connect to server with ssh, jump into a **backend** container with `docker exec -it <name> ./generate_admin_key.sh`
You'll receive Your admin key and You'll be able to log into dashboard

```
Admin key:
self-hosted-convex|010...
```

4. Now Your base is ready. Go to .env.local and finish setting up the connection.
5. Run `npm install` (only if Your image is latest, else use a proper version)
6. After that You can run `npx convex dev` and You should be ready to go!
7. Time to pick a theme! Go to [shadcn/create](https://ui.shadcn.com/create), create a theme, and simply use the received command to init this theme in Your project!

#### Troubleshooting

```
󰣇 dev/templates/convex-next-saas   main  !? ❯ npx convex dev
✖ Error: Unable to start push to https://backend-i8e44nvzhj8sxw4qm9tbu1f7.mentat.ovh

```

**Solution** - ensure both CLI and convex self-hosted cloud images versions are the same. If not - I suggest upgrading whatever version is lower to be higher.
