ExpressJS vs TypeORM: What are the differences?

Developers describe ExpressJS as "Sinatra inspired web development framework for node.js -- insanely fast, flexible, and simple". Express is a minimal and flexible node.js web application framework, providing a robust set of features for building single and multi-page, and hybrid web applications. On the other hand, TypeORM is detailed as "An ORM that can run in NodeJS and others". It supports both Active Record and Data Mapper patterns, unlike all other JavaScript ORMs currently in existence, which means you can write high quality, loosely coupled, scalable, maintainable applications the most productive way.

ExpressJS and TypeORM can be categorized as "Microframeworks (Backend)" tools.

Some of the features offered by ExpressJS are:

• Robust routing
• HTTP helpers (redirection, caching, etc)
• View system supporting 14+ template engines

On the other hand, TypeORM provides the following key features:

• automatically create the database table schemes based on your models
• transparently insert / update / delete to the database your objects
• map your selections from tables to JavaScript objects and map table columns to object properties

ExpressJS and TypeORM are both open source tools. ExpressJS with 45K GitHub stars and 7.55K forks on GitHub appears to be more popular than TypeORM with 14.4K GitHub stars and 1.85K GitHub forks.

Twitter, Intuit, and OpenGov are some of the popular companies that use ExpressJS, whereas TypeORM is used by Sofit Software, Yieldify, and Certain Lending. ExpressJS has a broader approval, being mentioned in 1202 company stacks & 4118 developers stacks; compared to TypeORM, which is listed in 9 company stacks and 22 developer stacks.
