如果你想渲染HTML文件，你可以使用sendFile()方法而不使用任何模板引擎

const express =  require("express")
const path = require("path")
const app = express()
app.get("/",(req,res)=>{
    res.sendFile(**path.join(__dirname, 'htmlfiles\\index.html')**)
})
app.listen(8000,()=>{
    console.log("server is running at Port 8000");
})

我在htmlfile里面有一个HTML文件，所以我使用路径模块来渲染index.html路径是节点中的默认模块。如果你的文件是在根文件夹刚刚使用

res.sendFile(path.join(__dirname, 'htmlfiles\\index.html'))

在app.get()中，它将工作

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>'));

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

app.get('/', function (req, res) {
res.sendfile(__dirname + '/public/index.html');
});

1） 最好的办法是设置静态文件夹。在你的主文件(app.js | server.js | ??):

app.use(express.static(path.join(__dirname, 'public')));

公共/ css / form . html public / css / style . css

然后你从“public”文件夹中获得静态文件:

http://YOUR_DOMAIN/form.html
http://YOUR_DOMAIN/css/style.css

2)

您可以创建您的文件缓存。 使用方法fs.readFileSync

var cache = {};
cache["index.html"] = fs.readFileSync( __dirname + '/public/form.html');

app.get('/', function(req, res){    
    res.setHeader('Content-Type', 'text/html');
    res.send( cache["index.html"] );                                
};);

我添加以下2行，它为我工作

    app.set('view engine', 'html');
    app.engine('html', require('ejs').renderFile);
