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
对于纯html，你不需要任何npm包或中间件
就用这个吧:
app.get('/', function(req, res) {
res.sendFile('index.html');
});
其他回答
res.sendFile(__dirname + '/public/login.html');
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>'));
如果你使用express@~3.0.0修改下面的代码行:
app.use(express.staticProvider(__dirname + '/public'));
就像这样:
app.set("view options", {layout: false});
app.use(express.static(__dirname + '/public'));
我做了它的描述在express api页面，它的工作就像魅力。有了这样的设置，你就不需要编写额外的代码，所以它很容易用于你的微产品或测试。
完整代码如下所示:
var express = require('express');
var app = express.createServer();
app.set("view options", {layout: false});
app.use(express.static(__dirname + '/public'));
app.get('/', function(req, res) {
res.render('index.html');
});
app.listen(8080, '127.0.0.1')
app.get('/', function (req, res) {
res.sendfile(__dirname + '/public/index.html');
});
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
