Libuv and libev, two I/O libraries with similar names, recently had the privilege to use both libraries to write something. Now let's talk about my own subjective expression of common and different points.

The topic of high-performance network programming has been discussed. Asynchronous, asynchronous, or asynchronous. Whether it is epoll or kqueue, it is always indispensable to the asynchronous topic.

Libuv is asynchronous, and libev is synchronous multiplexing IO multiplexing.

Libev is a simple encapsulation of system I/O reuse. Basically, it solves the problem of different APIs between epoll and kqueuq. Ensure that programs written using livev's API can run on most *nix platforms. However, the disadvantages of libev are also obvious. Because it basically just encapsulates the Event Library, it is inconvenient to use. For example, accept(3) requires manual setnonblocking after connection. EAGAIN, EWOULDBLOCK, and EINTER need to be detected when reading from a socket. This is a

Cordova Plugin Development Guide (iOS and Android)

Version: 0.0.1 updated 7/1/2016

Cordova Plugins are the magic that enable our mobile web app content to access the full power of Native SDKs underneath, but through clean JavaScript APIs that work the same across all platforms we target.

Building Cordova plugins is scary for many Cordova and Ionic developers, but it doesn't have to be. This simple guide walks through the what, when, why, and how of Cordova plugin development for iOS and Android.
