Spring Boot vs LoopBack – Node.js for developing Microservices


In this post, we will see comparison between Spring Boot and LoopBack – Node.js for implementing Microservices.

SpringBoot

Spring Boot is an open source Java-based framework used to create Microservices. It is developed by Pivotal Team and is used to build stand-alone and production ready spring applications.

Microservices architecture using Java Spring Boot

LoopBack – Node.js

Events and event-driven programming

Events are actions generated by the user or the system, like a click, a completed file download, or a hardware or software error.

Event-driven programming is a programming paradigm in which the flow of the program is determined by events. An event-driven program performs actions in response to events. When an event occurs it triggers a callback function.

Node.js is a platform that executes server-side JavaScript programs that can communicate with I/O sources like file systems and networks.

LoopBack

LoopBack is a highly extensible, open-source Node.js and TypeScript framework based on Express that enables you to quickly create APIs and microservices composed from backend systems such as databases and SOAP or REST services.

The diagram below demonstrates how LoopBack serves as a composition bridge between incoming requests and outgoing integrations. It also shows the different personas who are interested in various capabilities provided by LoopBack.

Advantages of LoopBack – Node.js and Spring Boot

LoopBack – Node.js Spring Boot
Lightweight, fast – loosely typed Java is statically-typed (type safety)
Javascript Community: growing rapidly Java Community: mature and thriving
Great for I/O tasks. Example: file writing and reading, network calls, Streaming Long-term support and maintainability for memory intensive applications
Single-threaded – low memory utilization Support for multi-threading
npm is constantly growing Many easily usable dependencies using Maven, Gradle

Disadvantages of LoopBack – Node.js and Spring Boot

LoopBack – Node.js

  • Doesn’t support multi-threading
  • Lack of strict type checking can lead to runtime problems
  • Not great for heavy computing – performance bottlenecks

Spring Boot

  • High memory utilization
  • Java is verbose
  • Contains lots of boilerplate code which makes debugging tough
  • May include unused dependencies – huge deployment binary file size.

Industry Usage of these technologies

Companies using Spring Boot

  • Amazon
  • Intuit
  • JP Morgan Chase & Co.
  • Capital One
  • Google
  • Microsoft

Companies using Node.js

  • FlightOffice
  • Symantec

  • GoDaddy.com
  • Sapient

LoopBack vs SpringBoot on various parameters

Criteria / Parameter SpringBoot LoopBack
Performance Long-term support and maintainability for memory intensive applications Great for I/O tasks. Example: file writing and reading, network calls, Streaming
Circuit Breaker Resilience4j Opossum
Hystrix Levee
Soap Client Apache CXF, Camel, Spring WebServiceTemplate loopback-connector-soap
JSON Manipulation/Validation Jackson, Spring Validator payload-validator
Orchestration and Routing support Apache CXF, Camel, Spring WebServiceTemplate, RestTemplate loopback-connector-soap, loopback-connector-rest
Caching support Spring Cache, external cache support Interception – CachingService, external cache support
Open API Contract first, API first both are supported Contract first, API first both are supported
Recommended For Building applications which consists of Memory intensive tasks Building applications which consists of I/O intensive tasks
