Available in about 190 countries, Netflix had around 221.64 Million subscribers in 2022 Q1. Up until 2015, Netflix used Java for data management. However, it lacked user experience with poor user wait times. Moreover, Netflix’s front-end used Javascript which didn’t communicate well with the JAVA backend.

Challenges With Netflix App

  • Development with Java takes time. Thus, deployment speed was low.
  • With synchronous loading, customizing UI as per customers’ needs was difficult to achieve.
  • Netflix was not able to capacitate its growing user base with the monolithic app design which was difficult to scale.
  • Backend-to-frontend transitions were not smooth, causing higher load times and latency.

Node JS Benefits for Netflix

  • User interface of the Netflix app was improved with Node JS development. The app startup time saw a dramatic 70% drop as it took a little over 1 second to load from its previous loading time, which was 5 to 10 seconds.
  • With the use of Node JS, it became easier to divide the interface into multiple smaller segments as it is microservice oriented
  • Backend-to-frontend transition was improved.

III. Travel and Hospitality


An American transportation conglomerate Uber uses Node JS for its several components alongside the Go programming language. It helps Uber attain complex tasks like connecting with over 600 APIs and trip execution.

Why Uber Chose Node JS?

  • It needed an environment that could process millions of user requests at a time. And the real-time, fast, and API-driven architecture of Node JS could help with that.
  • A powerful backend with numerous fragmented microservices powers the Node JS app infrastructure.

Node JS Benefits for Uber

  • Thanks to Node JS, it is capable of processing a huge number of requests at a time.
  • The executing trips component is entirely built using Node JS. Its asynchronous and single-threaded event loop further makes it a reliable technology.
