neo4jFastAPI

Fast API web server and Neo4j Graph Database back-end.

To get started

Add a dev.ini file inside config folder with following content. Assumption you have a neo4j instance running in background.
```
[neo4j]
uri=<enter_link_to_test_db_here>
username=<enter_test_username>
password=<enter_test_password>
```
Or you can use following command to do it. You will have to run this from root folder (i.e. neo4j_python/) of the project.
```
sh create_dev.sh
```
Note: This creates a dev.ini file with dummy info. You may want to change this as per your credentials.

In order to setup neo4j database (on linux), use this:
```
sudo docker run \                                                      
--name testneo4j \
-p7474:7474 -p7687:7687 \
-d \
-v $HOME/neo4j/data:/data \
--env NEO4J_AUTH=neo4j/test \
neo4j:latest
```
Above command creates a neo4j docker container exposing ports 7474 and 7687, and storing data at path $HOME/neo4j/data with database username as neo4j and password as test. For more info, refer here
Create a virtualenv, you can use any of your choice. I prefer using virtualenv.
```
python -m pip install virtualenv
python -m virtualenv --python=python
```
Install dependencies using this pip install -r requirements.txt
Run command uvicorn src.main:app --reload to start FastAPI webserver.
