This page provides a high-level overview of the project architecture.
The project repo is a mono-repo split up between directories for the
/docs. Each directory contains its own microservice(s). The
/traefik directory is intended for deployment in a production environment.
Why a mono-repo?
- Only client for the MetaGrid API back-end is the MetaGrid front-end
- Simplifies end-to-end development and testing -- ship code faster!
- Effective end-to-end code reviews
- Easy refactoring
- Reduced code complexity with standardizations across services
Simple Architecture Diagram
In root, there are multiple directories that contain microservices:
The user interface is rendered through React components which allow for modular and reusable design patterns.
To communicate with REST APIs, the front-end uses a promise-based HTTP client. Aside from the MetaGrid API back-end, here are other ESGF services used:
SearchAPI - This API is the interface connected to the search engine (Solr, Elastic Search)
wgetAPI - This API generates wget scripts for downloading datasets
MetaGrid's Django REST Framework back-end serves REST APIs, which send and receive JSON data via endpoints.
Traefik is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy. Traefik is used in the production deployment of MetaGrid.
