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
在Express 4.0.0中，你唯一要做的就是注释掉app.js中的两行:
/* app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade'); */ //or whatever the templating engine is.
然后将静态文件放到/public目录中。例如:/公共/ index . html
其他回答
app.get('/', function (req, res) {
res.sendfile(__dirname + '/public/index.html');
});
我不想依赖于ejs来简单地传递HTML文件，所以我只是自己写了一个小渲染器:
const Promise = require( "bluebird" );
const fs = Promise.promisifyAll( require( "fs" ) );
app.set( "view engine", "html" );
app.engine( ".html", ( filename, request, done ) => {
fs.readFileAsync( filename, "utf-8" )
.then( html => done( null, html ) )
.catch( done );
} );
表达4.倍
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') })
})
//...

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>'));
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
