The ts-dependency-injection-test
repository is a project primarily designed to explore and demonstrate the use of
dependency injection in TypeScript applications. This repository includes a simple example to help
developers understand the concept of dependency injection and how to implement it in TypeScript.
-
Dependency Injection in TypeScript: The repository explores the concept of dependency injection, a software design pattern that deals with how components get their dependencies.
-
Comprehensive Example: This repository provides an example demonstrating the different use cases and scenarios where dependency injection can be used.
Dependency Injection (DI) is a design pattern used in programming and software engineering to reduce the hard-coded dependencies among objects, making a system more modular, flexible, and efficient. It's often used as a technique for achieving Inversion of Control (IoC) between classes and their dependencies.
The fundamental idea behind Dependency Injection is that a class should not configure its dependencies statically, but should be configured from the outside. In simpler terms, a class should not create the objects it requires to function. Instead, these objects (dependencies) should be provided to the class (injected) by a controlling "container" or " injector" component.
- Node.js
- npm
- TypeScript
- Clone the repository to your local machine:
$ git clone https://github.com/dominique-boerner/ts-dependency-injection-test.git
- Install NPM packages:
$ cd ts-dependency-injection-test
$ npm install
- Run the application
$ npm run dev
You can look into the console of the application, where it should say "Connected to Postgres!".
