Dependency

• Typescript: TypeScript is a superset of JavaScript that adds static typing to the language. It compiles to JavaScript and can be used both in browser environments and in server-side environments like Node.js. Typesript also support generic class, type annotation, interface, enums, union type, private-protected memmber while JavaScript doesn't support.

• Node.js: Node.js is a runtime environment that enables you to run JavaScript code on the server side.

• Express: Express is a web application framework for Node.js that simplifies building APIs and web applications by providing a set of tools and utilities. It's like SpringBoot in Java, Django in Phyton, .Net for C#.

• MongoDB: MongoDB is a NoSQL database system designed for storing and managing unstructured or semi-structured data.

• Mongoose: Mongoose is an ODM library for MongoDB and Node.js. It simplifies interacting with MongoDB by providing a structured way to define schemas, models, and additional functionality.

• Inversify: It deals with how components or classes obtain their dependencies without creating them directly. Instead of creating dependencies within a class, dependencies are "injected" from the outside.

Features

• Establishing a MongoDB connection and transactions with mongoose ODM,
• Route handling mechanism using Express.js framework,
• Interface, enum, type alias, static typing, access modifiers, default parametre usage,
• Dependency injection using Inversify,
• Using Repository-MVC pattern,
• Exact string match search like ?search=text%20most,
• Data filtering like ?filter=likes:2-10,
• Pagination posts/pagination?pi=2,
• Sorting for fields ?sort=likes&orderby=asc | ?sort=title&orderby=desc | sort=author&orderby=desc,
• Query combination-query pool;

?sort=description&pi=3 ?sort=title&orderby=desc&pi=2 ?q=find%20me&sort=author&orderby=asc&pi=2 ?sort=likes&orderby=asc&filter=likes:3-24&pi=2 ?sort=description&orderby=descpription&filter=likes:3-10&pi=1

Architecture

Installation

git clone https://github.com/ahmetozydn/typescript-crud.git
cd yourproject
npm install
# After establishing your MongoDB connection!
npm start

Test

• postman is used to test endpoints.

• Query Combination;

pagination

• CRUD operations;

get a post	delete a post

get all posts	create a post

Further topics

• Architecture improvement
• Generating dynamic di for pagination class,
• Custom error handler mechanism,
• Authentication, authorization,
• Partial searching method for MongoDB because it doesn't provide efficient way
• Rate limiting, caching
• Handling file uploads through API endpoints.
• Understanding CORS and configuring it for your API.
• Support for multiple languages and locales.
