The Basics

Introduction

NestJS provides an out-of-the-box application architecture which allows developers and teams to create highly testable, scalable, loosely coupled and easily maintainable applications. NestJS combines the best concepts from Object-oriented programming  and Functional reactive programming.

Base file structure

npm i -g @nestjs/cli
nest new project-name

The project (back) is organised like so :

• node_modules & package.json → used for dependencies.
• tsconfig.json→ for typescript configuration.
• nodemon.json → nodemon configuration (used to be able to reload changes on save).
• tslint.json → for type int linting.
• nest-cli.json → for CLI.
• src/ → project’s files.
• src/main.ts → app entry file.
• src/app.module.ts → modules.
• src/app.controllers.ts → controllers.
• src/app.services.ts → providers.
• test/ → tests files.
