I am currently running Java on a tomcat as backend rest service. Which language would be good to migrate to. Good performance, future proof and I can find other people to maintain as well.
Hands down DRF: <a href="http://www.django-rest-framework.org/" rel="nofollow">http://www.django-rest-framework.org/</a><p>To do basic CRUD stuff, you write like 0 lines of real code. Just use a ViewSet, connect a Serilizer and a Model object. Everything just works and you can save the data into Postgres in no time.<p>Django is a massive community and you can do a lot more complex things than a CRUD app, but the easy stuff is just soo easy.
Since I develop 99% on Java I would recommend anything along the lines of Spring Boot, Dropwizard or Wildfly Swarm. With Dropwizard I can't say much since I only played with it a little, on the other hand having developed projects with Spring Boot and Swarm I can say both do the job really well, both seem pretty much future proof (even though many claim JEE is dead).<p>Personally I would go with Swarm since I feel there is less work configuring it. With the added advantage of being used to develop in JEE Environments.
If you are planning to build a microservice architecture I can recommend my project <a href="https://hemerajs.github.io/hemera-site/" rel="nofollow">https://hemerajs.github.io/hemera-site/</a> there is also a <a href="https://hapijs.com/" rel="nofollow">https://hapijs.com/</a> Plugin available.
It depends what you want the backend for - scale, speed of writing<p>Im primarily a java developer and wouldnt have a problem writing it using dropwizard or spring boot. But I'd also consider django-rest since i like django, or nodejs as alternatives
<a href="https://hapijs.com/" rel="nofollow">https://hapijs.com/</a><p>- High qualitity plugins
- Widely used e.g Paypal, Disney, Walmart
- Very good documentation<p>Personally one of the best web frameworks I've ever used.
