# Dify Backend API
|
|
|
|
## Usage
|
|
|
|
1. Start the docker-compose stack
|
|
|
|
The backend require some middleware, including PostgreSQL, Redis, and Weaviate, which can be started together using `docker-compose`.
|
|
|
|
```bash
|
|
cd ../docker
|
|
docker-compose -f docker-compose.middleware.yaml -p dify up -d
|
|
cd ../api
|
|
```
|
|
2. Copy `.env.example` to `.env`
|
|
3. Generate a `SECRET_KEY` in the `.env` file.
|
|
|
|
```bash
|
|
openssl rand -base64 42
|
|
```
|
|
3.5 If you use annaconda, create a new environment and activate it
|
|
```bash
|
|
conda create --name dify python=3.10
|
|
conda activate dify
|
|
```
|
|
4. Install dependencies
|
|
```bash
|
|
pip install -r requirements.txt
|
|
```
|
|
5. Run migrate
|
|
|
|
Before the first launch, migrate the database to the latest version.
|
|
|
|
```bash
|
|
flask db upgrade
|
|
```
|
|
|
|
⚠️ If you encounter problems with jieba, for example
|
|
|
|
```
|
|
> flask db upgrade
|
|
Error: While importing 'app', an ImportError was raised:
|
|
```
|
|
|
|
Please run the following command instead.
|
|
|
|
```
|
|
pip install -r requirements.txt --upgrade --force-reinstall
|
|
```
|
|
|
|
6. Start backend:
|
|
```bash
|
|
flask run --host 0.0.0.0 --port=5001 --debug
|
|
```
|
|
7. Setup your application by visiting http://localhost:5001/console/api/setup or other apis...
|
|
8. If you need to debug local async processing, you can run `celery -A app.celery worker -P gevent -c 1 --loglevel INFO -Q dataset,generation,mail`, celery can do dataset importing and other async tasks.
|
|
|
|
8. Start frontend
|
|
|
|
You can start the frontend by running `npm install && npm run dev` in web/ folder, or you can use docker to start the frontend, for example:
|
|
|
|
```
|
|
docker run -it -d --platform linux/amd64 -p 3000:3000 -e EDITION=SELF_HOSTED -e CONSOLE_URL=http://127.0.0.1:5001 --name web-self-hosted langgenius/dify-web:latest
|
|
```
|
|
This will start a dify frontend, now you are all set, happy coding! |
