Backend APIs & Databases with Node.js
Practical web skills, built project by project. Study at your own pace, practice with each lesson and finish with a useful piece of work.
Learn by doing, not just watching.
Description
Build a Node.js API connected to PostgreSQL with data validation, authentication concepts and deployment.
A frontend becomes a complete product when it can reliably store, retrieve and protect data. Learn to build a Node.js API, design REST endpoints, model relational data in PostgreSQL, validate input and apply essential authentication and authorization principles. You will connect a web client to the service and document how the system runs and fails, finishing with a deployed project API and repeatable setup instructions.
What you will learn
- Design clear REST resources and useful response/error shapes.
- Model relationships and write essential SQL queries.
- Apply validation, access-control principles and safe secret handling.
- Deploy, document and test a small backend service.
