decimal.js 金额计算
A Decimal is immutable in the sense that it is not changed by its methods.
0.3 - 0.1 // 0.19999999999999998
x = new Decimal(0.3)
x.minus(0.1) // '0.2'
x // '0.3'

formidable
A Node.js module for parsing form data, especially file uploads.
使用formidable 可以处理的 Content-Type
application/x-www-form-urlencoded 常见的form提交
multipart/form-data 文件提交
application/json 提交json格式的数据
在实际开发中，很明显可以用bodyparser和multer来分别处理表单和文件，也可以只用formidable，按需取用即可。
