Build a Data Access Layer with PostgreSQL and Node.js
The Data Access Layer (DAL) is the most critical part of any application. This is where the code integrates with an external source of truth like a database. In this take, we'll show you how to build a DAL that talks to Postgres via Node. Then we'll go into best practices like Clean Architecture and what this means in practical terms. Ready? Let’s go! First, a quick note about the code: The code will have modern niceties like TypeScript, unit tests, and will tackle potential scalability issues.
