闪光灯，连接闪光灯和快速闪光灯之间的区别 [英] difference between flash, connect-flash and express-flash

问题描述

我仍然对flash，connect-flash和express-flash到底有什么区别感到困惑.

I'm still kinda confused on what exactly is the difference between flash, connect-flash and express-flash.

安装:

• flash npm install flash

express-flash : npm install express-flash

连接闪存: npm install connect-flash

用法:

闪光灯:

app.use(session()); // session middleware 
app.use(require('flash')());

app.use(function (req, res) {
  // flash a message 
  req.flash('info', 'hello!');
  next();
})

连接闪存

var flash = require('connect-flash');
var app = express();

app.configure(function() {
  app.use(express.cookieParser('keyboard cat'));
  app.use(express.session({ cookie: { maxAge: 60000 }}));
  app.use(flash());
});

快速闪存，它甚至要求用法的设置方式应与连接闪存相同:

express-flash It even request that the usage should set up the same way you would connect-flash:

var flash = require('express-flash'),
    express = require('express'),
    app = express();

  app.use(express.cookieParser('keyboard cat'));
  app.use(express.session({ cookie: { maxAge: 60000 }}));
  app.use(flash());

有人可以解释吗?

推荐答案

这三个软件包之间确实没有太大的区别.他们都以自己的方式完成同一件事.两者之间的区别是:

There really is no drastic difference between the three packages. They all accomplish the same thing in their own way. The difference between the three are:

1. flash 由Express团队编写，使其成为Express的官方中间件.
2. 连接闪存，如自述文件所述:

1. flash is written by the Express team, making it an official middleware for Express.
2. connect-flash as stated from the README:

此中间件是从Express 2.x中提取的

This middleware was extracted from Express 2.x

因此，从某种意义上说，它与 flash 类似，除了Express 2.x版本中的旧版本.但是，顾名思义，它是用于 Connect 框架的，但通常是任何 connect-* 软件包可与Express配合使用.

So in a sense this is similar to flash except a legacy version of it from Express 2.x days. However, the name suggests it was meant for the Connect framework, but usually any connect-* packages work fine with Express.

1. 快速闪存只是连接闪存的包装.您可以在源代码中此处.

1. express-flash is just a wrapper around connect-flash. You can see that in the source code here.

从npm统计数据来看，

在所有这三种方法中， connect-flash 似乎是最常用的方法.

Out of all three, connect-flash seems to be the most used judging from npm stats.
