# ️🔨 Development

Run the following commands to install:

For Linux/macOS:
```sh
git clone https://github.com/open-webui/open-webui.git
cd open-webui/

# Copying required .env file
cp -RPp .env.example .env

# Start frontend server
npm install
npm run dev

cd ./backend

# Optional: To install using Conda as your development environment, follow these instructions:
# Create and activate a Conda environment
conda create --name open-webui-env python=3.11
conda activate open-webui-env

# Install dependencies
pip install -r requirements.txt -U

# Start the application
bash dev.sh
```

## In docker container
Assuming you have already cloned the repo and created a `.env`.

1. Create a new file `compose-dev.yaml`. The following uses [Docker compose watch](https://docs.docker.com/compose/file-watch/) to automatically detect changes in the host filesystem and sync them to the container. 

```yaml
name: open-webui-dev

services:
  ollama:
    volumes:
      - ollama:/root/.ollama
    container_name: ollama
    pull_policy: always
    tty: true
    restart: always
    image: ollama/ollama:${OLLAMA_DOCKER_TAG-latest}

  frontend:
    build:
      context: .
      target: build
    command: ["npm", "run", "dev"]
    depends_on:
      - backend
    extra_hosts:
      - host.docker.internal:host-gateway
    ports:
      - "3000:5173"
    develop:
      watch:
        - action: sync
          path: ./src
          target: /app/src
        - action: rebuild
          path: package.json

  backend:
    build:
      context: .
      target: base
    command: ["bash", "dev.sh"]
    env_file: ".env"
    environment:
     - ENV=dev
     - WEBUI_AUTH=False
    volumes:
      - data:/app/backend/data
    extra_hosts:
      - host.docker.internal:host-gateway
    ports:
      - "8080:8080"
    restart: always
    develop:
      watch:
        - action: sync
          path: ./backend
          target: /app/backend
          ignore:
            - backend/data
        - action: rebuild
          path: backend/requirements.txt

volumes:
  data: {}
  ollama: {}
```
2. To start the containers, run `docker compose -f compose-dev.yaml up --watch`. The webapp will be available at `http://localhost:3000`
3. To stop, hit `ctrl-c` or run `docker compose -f compose-dev.yaml down

**What this does:**
- Exposes port `3000` on the host for frontend, and port `8000` for the api, enables FastAPI API docs at `http://localhost:8080/docs`
- Starts both the frontend Vite server and the backend server in hot reload mode, so changes trigger an automatic refresh
- Syncs `/backend` and `/src` on the host machine with their respective directories in the containers

### Pipelines 
If you are using [pipelines](https://docs.openwebui.com/pipelines/), you can add the following:

:::info
This uses volume bind-mounts, which are distinct from named volumes. You can read more about the difference [here](https://docs.docker.com/storage/bind-mounts/)
:::

```yaml
services:
  pipelines:
    ports:
      - "9099:9099"
    volumes:
      - ./pipelines:/app/pipelines
    extra_hosts:
      - "host.docker.internal:host-gateway"
    restart: always
```
