This example application demonstrates how easy it is to get started with http://neo4j.com/developer[Neo4j] in Python.
It is a very simple web application that uses our Movie graph dataset to provide a search with listing, a detail view and a graph visualization.
We offer two different ways to run the application: synchronous and asynchronous (using asyncio
).
=== The Stack
These are the components of our Web Application:
Provision a database quickly with https://sandbox.neo4j.com/?usecase=movies[Neo4j Sandbox] or https://neo4j.com/cloud/aura/[Neo4j Aura].
=== Setup
Install Python 3.7-3.12.
Then get yourself set up with link:http://docs.python-guide.org/en/latest/dev/virtualenvs/[virtualenv] so we don't break any other Python stuff you have on your machine. After you've got that installed let's set up an environment for our app:
The next step is to install the dependencies for the app with pip (or pip3 for python3):
sync:
async:
=== Run locally
And finally let's start up a web server:
sync:
python movies_sync.py
async:
python movies_async.py
Navigate to http://localhost:8080 and you should see your first Neo4j application
=== Changing the Database By default, this example application connects to a remote Neo4j database run by Neo4j for this purpose. If you want to connect to a local database, follow these instructions.
Start your local Neo4j Server (http://neo4j.com/download[Download & Install]),
open the http://localhost:7474[Neo4j Browser]. Then install the Movies data set
with :play movies
, click the CREATE
statement (in some versions, this will not
be directly on the first page of the movies example), and hit the triangular
"Run" button.
If you haven't touched the configuration of your Neo4j Server, the database will
be reachable at neo4j://localhost:7687
.
Use environment variables to let the application know where to connect to the database.
sync:
NEO4J_URI=neo4j://localhost:7687 NEO4J_DATABASE=neo4j NEO4J_USER="
async:
NEO4J_URI=neo4j://localhost:7687 NEO4J_DATABASE=neo4j NEO4J_USER="
=== All Configuration Options
Here are all environment variables that can be used to configure the application.
[%header,cols=2*] |=== |Environment Variable Name |Default Value (or N/A)
|PORT |8080
|NEO4J_URI |neo4j+s://demo.neo4jlabs.com
|NEO4J_USER |movies
|NEO4J_PASSWORD |movies
|NEO4J_DATABASE |movies |===
