I don't need to introduce this. coders understand it.

At SoundCloud, we built a product API for our customers. Or, our main website, mobile client and mobile app are the first customers of the API. Behind the API is a domain-based service: SoundCloud basically operates in the form of service-oriented architecture.

Cards are a reliable vehicle for a large amount of content, both for design and for development. Each card can carry different elements, as different modules, to achieve different functions.
So, you can have a card play the video, the next card is linked to another application, and t

Peter Bourgon is the creator of Go Kit.
Strong majority of audience here have heard of Go kit.
What is Go kit?
Go Kit is a toolkit for microservices. In the early days, this meant something very specific at SoundCloud (where Peter worked at the time). They were using Finagle for microservices, but there wasn ' t a go equivalent, so Go started to lose favor among the tea

This means that you spend less time in code review and controversy over code styles and formats, and more time to solve the root causes of your problems. If you're just starting out with go and want to learn more, here are some resources to look at.

In the process of using go, we sometimes introduce some third-party libraries to use, and the usual way is to use go get , but this way has a very serious problem, assuming that the third-party library updated the relevant interface, it is very likely that you will not be able to use, so we set a very good package management mechanism.

Suitable for network machines
For web development
The go language is designed with software engineering as its goal, so it has these advantages:
A clear Reliance
A clear grammar
Clarity of semantics
Simple model (garbage collection and concurrency)
Convenient tools (Go tool, Gofmt, Godoc, Gofix, etc.)
