What does Uber do in the development language?

Uber blends the booming go and node. JS languages into their systems. Uber's website reliability engineer, Tom Croucher, described the company's language platform in detail at the recently held node. JS Interactive conference in Poland.

Uber's task dispatch system is running on node, which is a JavaScript platform running on the server side. When a customer opens an app or website to make a car reservation or calls other APIs to view available vehicle information, most of these services are provided through the platform running on node, Croucher said.

"Most of the work here is done by node, and we've been using node since the first year of the company," Croucher continues. He also stressed that Uber was one of the first users of node and was one of the first "really big businesses based on node".

But node. JS is not the only language that Uber uses. Google's go language also holds a place in Uber. "We've already started using go to do some of the tasks, and part of it involves a pretty high performance demand. We started with the intention of node to write, but in order to get better performance of the system, we are now going to use go to rewrite these special parts. “

At the same time, Uber is currently using the older node 0.10 version, because it needs to see "the new version can bring significant benefits" before the upgrade. "Node. JS Foundation Manager Mikeal Rogers asked users to upgrade node. js to version 4."

In addition to trending node. js and go, Python is one of the languages that Uber prefers. "I find that Python is actually one of the few techniques that Uber uses," Croucher continues. "It's very helpful for us to choose between different pools of talent, so many of our systems are written using Python. We have found that a large number of Python developers have written a great deal of good service, especially in some business areas and some other special areas. “
