This repository is a part of the master's thesis "Graph-based representation, integration, and analysis of neuroscience data — The case of the murine basal ganglia". In this thesis, we investigate aspects of graph-based data representation in the neuroscience domain. The data set basis is a relational database published by Bjerke et al. (2019) of quantitative neuroanatomical data about the healthy rat and mouse basal ganglia (DOI:10.25493/DYXZ-76U).
The API is based on the GRANDstack Starter - GraphQL API. For more information on the GRANDStack, visit https://grandstack.io/. This directory contains a GraphQL API of the murine basal ganglia graph database. The application connects with a Neo4j database instance.
The API solution is deployed through Heroku and is available at https://basal-ganglia-graphql.herokuapp.com/graphql.
Install dependencies:
npm install
Start the GraphQL service in development mode:
npm run start-dev
This will start the GraphQL service (by default on localhost:4000) where you can issue GraphQL requests or access GraphQL Playground in the browser:
Configuration is done with environment variables specified in .env.
The application needs the following variables: The Neo4j database password: NEO4J_PASSWORD, The Neo4j database bolt URL: NEO4J_URI, and The Neo4j database username: NEO4J_USER.
