Dify Backend API

Usage

Start the docker-compose stack

The backend require some middleware, including PostgreSQL, Redis, and Weaviate, which can be started together using docker-compose.
```
cd ../docker
docker-compose -f docker-compose.middleware.yaml -p dify up -d
cd ../api
```
Copy .env.example to .env

Generate a SECRET_KEY in the .env file.

sed -i "/^SECRET_KEY=/c\SECRET_KEY=$(openssl rand -base64 42)" .env

If you use Anaconda, create a new environment and activate it
```
conda create --name dify python=3.10
conda activate dify
```
Install dependencies
```
pip install -r requirements.txt
```
Run migrate

Before the first launch, migrate the database to the latest version.
```
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
```

Start backend:

flask run --host 0.0.0.0 --port=5001 --debug

Setup your application by visiting http://localhost:5001/console/api/setup or other apis...
If you need to debug local async processing, please start the worker service by running celery -A app.celery worker -P gevent -c 1 --loglevel INFO -Q dataset,generation,mail. The started celery app handles the async tasks, e.g. dataset importing and documents indexing.
