Nodejs Study Notes

Fragmented learned a few days nodejs, progress has been stagnant, today sank heart to take a good look at the next Nodejs introduction and code. I also tried to play the next, is a bit of a primer.

Here to make a study note.

First, the next nodejs is introduced briefly. Referring to the introduction of Daniel:

Nodejs is written by the Chrome browser, V8 engine, C + +, which is essentially a JavaScript runtime environment.

The installation and environment variable configuration for the next nodejs is described below.

Download/install Nodejs is very simple, basic and a common installer process.

, look for the official website (all English official website, the civil service net always feel is a cottage): Nodejs

The most prominent location on the official website has a direct download address, Nodejs directly read your current system, and give the adaptation version. (Very human)

After the download is installed, Nodejs will automatically configure the local environment variables to detect if the Nodejs is configured and enter the NODE-V detection version number on the DOS command line.

If there is no version number out, please manually configure the environment variables, configuration methods refer to the JDK configuration method, do not understand the children's shoes themselves Baidu.

The use of Nodejs can be used in Windows-brought cmd, or you can download git tools yourself.

PS: To mention, this download really look at the speed, do not move the spray I did not remind. Really can not stand the use of Windows cmd, anyway, I used pretty handy.
