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?
当前回答
要在节点中呈现Html页面，请尝试以下操作，
app.set('views', __dirname + '/views');
app.engine('html', require('ejs').renderFile);
你需要像这样通过npm安装ejs模块: NPM安装ejs—保存

我想允许对“/”的请求由Express路由处理，而以前它们是由静态中间件处理的。这将允许我渲染index.html的常规版本或加载连接+最小化JS和CSS的版本，这取决于应用程序设置。受到Andrew Homeyer回答的启发，我决定将我的HTML文件(未修改)拖到views文件夹中，并像这样配置Express
app.engine('html', swig.renderFile);
app.set('view engine', 'html');
app.set('views', __dirname + '/views');
创建了一个这样的路由处理器
app.route('/')
.get(function(req, res){
if(config.useConcatendatedFiles){
return res.render('index-dist');
}
res.render('index');
});
结果很好。
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'));
我通常用这个
app.configure(function() {
app.use(express.static(__dirname + '/web'));
});
只是要小心，因为它会共享/web目录中的任何内容。
我希望这对你们有帮助
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>'));

res.sendFile(path [， options] [， fn])
发送.html文件，没有模板引擎…
//...
// Node modules
const path = require('path')
//...
// Set path to views directory
app.set('views', path.join(__dirname, 'views'))
/**
* App routes
*/
app.get('/', (req, res) => {
res.sendFile('index.html', { root: app.get('views') })
})
//...
