multer，multiparty和connect-multiparty + Nodejs之间的区别 [英] Difference between multer, multiparty and connect-multiparty + Nodejs

问题描述

是Node world的新手.

Am new to Node world.

UseCase:

在Angular前端上传XLS文件有一个简单的场景， 在Node上处理它们，进行一些操作，然后将JSON保存到 Mongo DB.

Was having a simple scenario of uploading XLS files on Angular front, process them on Node, make some manipulations and then save JSON on to Mongo DB.

从Angular接收文件之后，我正在寻找解析/处理Node上文件的最佳方法，然后在这些著名的节点模块上找到文章-multer，multiparty和connect-multiparty.

After receiving files from Angular, i was searching what is the best way to parse / process a file on Node and then came across articles on these famous node modules - multer, multiparty and connect-multiparty.

每篇文章都解释了如何使用相应的模块，却找不到任何告诉何时使用哪个模块的模块.

Every article explains how to use corresponding module and couldn't find any one telling which one to be used when.

我发现multer主要用于试图在磁盘存储上保存文件的情况，而这不足以满足我的用例.

I found that multer is mainly used when you are trying to save a file on Disk Storage and that doesn't suffice my use case.

所以我应该忽略multer还是实际使用它?

So should i ignore multer or actually use it ?

我什么时候应该实际使用multiparty和connect-multiparty?

When should i actually use multiparty and connect-multiparty ?

推荐答案

如何在ExpressJS 4.x中上传文件

有一些模块可以直接解析多格式数据，并表示基于这些格式构建的中间件.

There are modules to parse multiform data directly, and express middleware built on top of these.

Github star最直接解析的前三个模块是可结节点(3376)，busboy(814)，多结节点(557).

The top three modules by Github stars for parsing directly are node-formidable (3376), busboy (814), node-multiparty (557).

顶级中间件是multer(基于2515星的busboy构建). connect-multiparty上有一条注释，建议您不要使用它. connect-busboy已经四年没有更新了.

The top middleware is multer (built on busboy, 2515 stars). connect-multiparty has a note suggesting not to use it. connect-busboy has not been updated in four years.

基于此，如果您想要Express中间件，我建议使用可结点的节点，busboy或multer.

Just based on this I'd suggest node-formidable, busboy, or multer if you want Express middleware.

还请注意，multer具有MemoryStorage内存存储引擎.

Also note that multer has a MemoryStorage memory storage engine.
