The express-typescript is a source code repository for building a REST API with Express and TypeScript. It corresponds to a blog post series that covers various aspects of setting up a REST API using Express, TypeScript, Swagger, Docker, PostgreSQL, Typeorm, Jest for unit testing, and building a production server and Docker image.
Express.js is a simple Node.js framework for single, multi-page, and hybrid web applications.
TypeScript is a superset of JavaScript, providing optional static typing, classes, interfaces, and other features that help developers write more maintainable and scalable code. TypeScript's static typing system can catch errors at compile-time, making it easier to build and maintain large applications.
