I need to create an API, but I don't know what framework to use. What would you choose, of you were me, and scalability is a quite important factor?

  • Spring Boot

    Spring Boot

    • Assuming you are going to construct a REST API, you can use NestJS. This framework integrates with the microservice pattern very well. Spring Boot is also a great and tested option.

  • RxJS

    A reactive programming library for JavaScript

    • However, if you really expect a lot of users (especially concurrent ones) to use your API, you should delve into the world of reactive programming. Use tools like RxJS (JS/TS) or Project Reactor (Java) in such a case, preferably in combination with a broker like Kafka or RabbitMQ. R2DBC is also great for a data store. Then of course if you want to go one step further, there also exists the less popular but very interesting Actor model which Akka easily has ported into Java.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • Nest

    A progressive Node.js framework for building efficient, scalable, and enterprise-grade server-side applications with TypeScript/JavaScript 🚀

    Build highly concurrent, distributed, and resilient message-driven applications on the JVM
