The e-Manifest App for EPA

View the live application »

Build Status Code Climate

Application architecture

This is a Rails application with a Postgres database containing both API endpoints and web views. The API is a JSON REST API. The web app and the API use the same database.

We use Elasticsearch to search for manifest records. Elasticsearch offloads read-access from the database and provides full-text search capabilities painful to apply directly to a database.

Redis is used for Sidekiq job processing. The Redis + Sidekiq solution offloads the database/Elasticsearch syncing to an async process.
