Is there a module which can pretty print json format data in Nodejs?

yes, a module with thousands of dependency

JSON.stringify(o, null, 2)

楼上+1，原生支持

`JSON.stringify` or `require('util').inspect`

Your English is so good, why not search that by yourself?

I just put your title (as it is) into google, just 1 second or less later, the first item of the result is what you want.

英语不好真的不用硬来，本来就是中文社区。

@bluetoy 原来如此，推荐你一个好方案！在 chrome 里安装 google 输入法插件，在 firefox 里搜一下 pinyin 之类的关键词也有插件的，我就是这样用，系统级别的输入法我就不装了，因为在 linux 里我基本上都是在网页里才需要中文输入法。
