I am trying to render HTML with res.sendFile using absolute path but it is sending encoded HTML in a pre tag so the response shows HTML unrendered in a pre tag.
Here is my express code
app.get('/', (req,res) =>{
res.sendFile(__dirname+'/a.html');
});
and here is my html file
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<h1>I am Html</h1>
</body>
</html>
and here is the result when I navigate to localhost:8800/
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<h1>I am Html</h1>
</body>
</html>
It prints the html as it is without rendering it.
You need to use res.render() to actually render the html.
I can't post a comment because I don't have enough reputation, but what I was going to say is that I ran your code on my system (OSX Mojave 10.14.6, Node v12.13.0, latest versions of Firefox and Chrome) with some additions to make it work (posted below), and didn't run into your problem. Perhaps you have some other code or middleware that you haven't posted. Also, you are correct that res.render is for templates.
const express = require('express');
const app = express();
const port = 3000;
const path = require('path');
app.get('/', (req, res) => {
res.sendFile(__dirname + '/a.html');
// better to use the path API, but both work
// res.sendFile(path.join(__dirname, 'a.html'));
});
app.listen(port, () => console.log(`Example app listening on port ${port}!`));
The HTML is the same. Folder structure is:
.
├── app.js
├── a.html
Could you post more details?

I am trying to include a partial on the page with my backend coming later. I want to use an event listener button. It dosent work. I am using express.ejs and node.js with vanilla js.

I have a bucket in s3 : http://www.sentencex.com.s3-website-us-east-1.amazonaws.com/
The root page is index.html.
Now I use vscode write a new html file, hello world from local.html,use AWS console upload to my bucket.
When Url route to:
http://www.sentencex.com.s3-website-us-east-1.amazonaws.com/hello%20world%20from%20local.html
it return the 'hello world from local' page from browser.
But When I use lambda to create a file called hello world from lambda.html.
This is My code in lambda:
const AWS = require('aws-sdk')
const s3 = new AWS.S3()
exports.handler = async (event) => {
let html = `
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<h1 class="sayHello">Hello</h1>
<script src="./app.js" type="module"></script>
</body>
</html>
`
let putHtmlParam = {
Body:html,
Metadata: {
'Content-Type': 'text/html'
},
Bucket:'www.sentencex.com',
Key:'hello world from lambda.html',
}
let putHtmlResult = await s3.putObject(putHtmlParam).promise()
return putHtmlResult
};
I can upload this hello world from lambda.html to my s3.
But when the url route to
http://www.sentencex.com.s3-website-us-east-1.amazonaws.com/hello%20world%20from%20lambda.html
It can not open the page in the browser directly.It has to download the page and read it from local.
I'm using ajax to update a value without refreshing the page.

I try to make an HTML page with a video. I launch my application on windows 7. All application operates as expected except media. The media file layouts in the 'public' folder in my project. But it doesn't play. The browser console gives the error: "GET http://localhost:8000/1.webm 404 (Not Found)". How can I launch the video in my application?
index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta http-equiv="X-UA-Compatible" content="ie=edge" />
</head>
<body>
<video src="public/1.webm" controls>
</video>
</body>
</html>
index.js:
var express = require("express");
var path = require("path");
var app = express();
app.get("/", function(req, res) {
res.sendFile(__dirname + "/views/index.html");
});
app.use(express.static(path.join(__dirname, "public")));
app.listen(8000);
console.log("Server has started!");
I'm trying to use nodejs to read the IP address and display on a html page, here is what I've done so far:
app.js
const express =require('express')
const app = express();
var os = require( 'os' );
var path = require('path')
app.get('/',function(req,res){
res.sendFile(path.join(__dirname+'/index.html'))
})
var networkInterfaces = Object.values(os.networkInterfaces())
.reduce((r,a)=>{
r = r.concat(a)
return r;
}, [])
.filter(({family, address}) => {
return family.toLowerCase().indexOf('v4') >= 0 &&
address !== '127.0.0.1'
})
.map(({address}) => address);
var ipAddresses = networkInterfaces.join(', ')
console.log(ipAddresses);
app.get('/DHCP',(req,res)=>{
return networkInterfaces[1];
});
app.listen(1000)
and the index.html:
<!DOCTYPE html>
<html>
<head>
<meta charset='utf-8'>
<meta http-equiv='X-UA-Compatible' content='IE=edge'>
<title>Page Title</title>
<meta name='viewport' content='width=device-width, initial-scale=1'>
<link rel='stylesheet' type='text/css' media='screen' href='main.css'>
<script src='main.js'></script>
</head>
<body>
<p id="DHCP" align="middle"> DHCP:</p>
</body>
</html>
I'm new to web dev world so I just don't get how can I do it !
thanks in advance !
You need to pick a template engine (e.g. pug), then call res.render() with an html template modified according your template engine's syntax.
use something like this:
<p id="DHCP" align="middle">{{DHCP:}}</p>
This works if you previously set your application to use HTML instead of any View Engine.
