## ⚡Quick Start

Download and Install [NodeJS](https://nodejs.org/en/download) >= 18.15.0

1. Install Flowise
    ```bash
    npm install -g flowise
    ```
2. Start Flowise

    ```bash
    npx flowise start
    ```

    With username & password

    ```bash
    npx flowise start --FLOWISE_USERNAME=user --FLOWISE_PASSWORD=1234
    ```

3. Open [http://localhost:3000](http://localhost:3000)

## 🐳 Docker

### Docker Compose

1. Go to `docker` folder at the root of the project
2. Create `.env` file and specify the `PORT` (refer to `.env.example`)
3. `docker-compose up -d`
4. Open [http://localhost:3000](http://localhost:3000)
5. You can bring the containers down by `docker-compose stop`

### Docker Image

1. Build the image locally:
    ```bash
    docker build --no-cache -t flowise .
    ```
2. Run image:

    ```bash
    docker run -d --name flowise -p 3000:3000 flowise
    ```

3. Stop image:
    ```bash
    docker stop flowise
    ```

## 👨‍💻 Developers

Flowise has 3 different modules in a single mono repository.

-   `server`: Node backend to serve API logics
-   `ui`: React frontend
-   `components`: Langchain components

### Prerequisite

-   Install [Yarn v1](https://classic.yarnpkg.com/en/docs/install)
    ```bash
    npm i -g yarn
    ```

### Setup

1. Clone the repository

    ```bash
    git clone https://github.com/FlowiseAI/Flowise.git
    ```

2. Go into repository folder

    ```bash
    cd Flowise
    ```

3. Install all dependencies of all modules:

    ```bash
    yarn install
    ```

4. Build all the code:

    ```bash
    yarn build
    ```

5. Start the app:

    ```bash
    yarn start
    ```

    You can now access the app on [http://localhost:3000](http://localhost:3000)

6. For development build:

    - Create `.env` file and specify the `PORT` (refer to `.env.example`) in `packages/ui`
    - Create `.env` file and specify the `PORT` (refer to `.env.example`) in `packages/server`
    - Run

        ```bash
        yarn dev
        ```

    Any code changes will reload the app automatically on [http://localhost:8080](http://localhost:8080)

## 🔒 Authentication

To enable app level authentication, add `FLOWISE_USERNAME` and `FLOWISE_PASSWORD` to the `.env` file in `packages/server`:

```
FLOWISE_USERNAME=user
FLOWISE_PASSWORD=1234
```

## 🌱 Env Variables

Flowise support different environment variables to configure your instance. You can specify the following variables in the `.env` file inside `packages/server` folder. Read [more](https://docs.flowiseai.com/environment-variables)
