Developing

The COA framework consists of two sub-packages which each run a server. There is a backend API server, and a frontend server that serves React code.

Documentation Contents

• Environment Variables
• NestJS for information on the backend API server
• Working with the Database - running dev databases, migrations, etc.
• GraphQL, Implementing an API
• GraphQL, Running Queries from React Code

Key Technologies

• NestJS powers the backend API in the backend sub-package.
• TypeORM provides the database interface, and manages migrations.
• We encourage use of GraphQL for your API. NestJS provides a GraphQL server framework.
• The frontend uses Apollo Client to fetch data from the GraphQL API.
• Next.js servers the frontend, and provides routing, server-side rendering, and other features.
