我有一个基本的Node.js应用程序，我试图使用Express框架启动。我有一个views文件夹，其中有一个index.html文件。但是我在加载网页时收到以下错误:
Error: Cannot find module 'html'
下面是我的代码。
var express = require('express');
var app = express.createServer();
app.use(express.staticProvider(__dirname + '/public'));
app.get('/', function(req, res) {
res.render('index.html');
});
app.listen(8080, '127.0.0.1')
我错过了什么?

对于我的项目，我创建了这样的结构:
index.js
css/
reset.css
html/
index.html
这段代码为/请求服务index.html，为/css/reset.css请求服务reset.css。很简单，最好的部分是它自动添加缓存头。
var express = require('express'),
server = express();
server.configure(function () {
server.use('/css', express.static(__dirname + '/css'));
server.use(express.static(__dirname + '/html'));
});
server.listen(1337);

index.js
var express = require('express');
var app = express();
app.use(express.static(__dirname + '/public'));
app.get('/', function(req, res) {
res.render('index.html');
});
app.listen(3400, () => {
console.log('Server is running at port 3400');
})
将index.html文件放到公共文件夹中
<!DOCTYPE html>
<html>
<head>
<title>Render index html file</title>
</head>
<body>
<h1> I am from public/index.html </h1>
</body>
</html>
现在在终端上运行以下代码
节点index.js
It is very sad that it is about 2020 still express hasn't added a way to render an HTML page without using sendFile method of the response object. Using sendFile is not a problem but passing argument to it in the form of path.join(__dirname, 'relative/path/to/file') doesn't feel right. Why should a user join __dirname to the file path? It should be done by default. Why can't the root of the server be by defalut the project directory? Also, installing a templating dependency just to render a static HTML file is again not correct. I don't know the correct way to tackle the issue, but if I had to serve a static HTML, then I would do something like:
const PORT = 8154;
const express = require('express');
const app = express();
app.use(express.static('views'));
app.listen(PORT, () => {
console.log(`Server is listening at port http://localhost:${PORT}`);
});
The above example assumes that the project structure has a views directory and the static HTML files are inside it. For example, let's say, the views directory has two HTML files named index.html and about.html, then to access them, we can visit: localhost:8153/index.html or just localhost:8153/ to load the index.html page and localhost:8153/about.html to load the about.html. We can use a similar approach to serve a react/angular app by storing the artifacts in the views directory or just using the default dist/<project-name> directory and configure it in the server js as follows:
app.use(express.static('dist/<project-name>'));
如果您不需要使用views目录，只需将html文件移动到下面的公共目录即可。
然后，将这一行添加到app.configure中，而不是'/views'。
server.use(express.static(__dirname + '/public'));

你可以让jade包含一个普通的HTML页面:
在视图/ index.jade
include plain.html
在视图/ plain.html
<!DOCTYPE html>
...
而app.js仍然可以渲染jade:
res.render(index)
