I'm using EJS for the first and I'm a bit confused. What's happening is that I have a list.ejs file created inside my views file. And a index.html outside I'm using a else if statement to do the logical thinking to the render my EJS file answer but when I call the res.render if I have the index.html, it displays it instead of my list.EJS, there are no errors or anything
app.js
const express = require('express');
const app = express();
const port = 3000;
app.set('view engine', 'ejs');
app.use(express.urlencoded({ extended: true }));
app.use(express.static(__dirname));
app.get('/', (req, res) => {
let today = new Date();
let currentDay = today.getDay();
let day = ""
if (currentDay === 6 | currentDay === 0) {
day = "Weekend"
} else {
day = "Weekday!"
}
res.render('list', {dayOfWeek: day})
})
app.listen(port, () => {
console.log('Listening on port ' + port);
});

The index.html is just a h1 Send Help..
What am I doing wrong?
I removed the index.html file and it works but it shouldn't be like that... Right?
Add this code:
const path=require("path");
app.set('views', path.join(__dirname));

I am trying to dis displayt a simple variable in the browser using ejs.
the server.js file
const express = require('express');
const mongoose = require('mongoose');
const app = express();
const ejs = require('ejs');
app.set('view engine', 'ejs');
mongoose.connect('mongodb+srv://<username>:<password>#cluster0.asnad.mongodb.net/?retryWrites=true&w=majority');
app.get('/',(req, res) => {
let name = 'bl;ah';
res.render('index', {
userName: name
});
})
app.listen(4000, function() {
console.log('server is running');
})
the index.ejs file is in a directory called views in the home directory mongo-html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=0.1">
<title>Document</title>
</head>
<body>
<h1>
<%= userName %> here
</h1>
</body>
</html>
The command to run the whole thing is,
nodemon server.js
Previously I installed Express and Nodemon.
I am following Marina Kim's tutorial from youtube https://www.youtube.com/watch?v=yH593K9fYvE
I don't know why this variable is not displaying.
Any help would be greatly appreciated.
Thanks,
I have some bool and string variable in the server side that should be passed to client side.
how can I implement this?
in my html file I want a h1 tag if my flag in the server side is true and if flag is false it just another work. at the first my flag is false.
server.js:
app.get('/' , (req, res) => {
res.sendFile(path.join(__dirname+'/views/UiOfServer.html'));
});
I found the anwser myself, the solution is useing EJS. because server rendering is so eazy with that.
I changed my html file to EJS file and my question solved. my code is:
index.ejs:
<!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>example of EJS</title>
</head>
<body>
<% if(flag){ %>
<h1><%= username %></h1>
<% }
else{ %>
<!-- some work -->
<% } %>
</body>
</html>
server.js:
let express = require('express');
let path = require('path');
let app = express();
let router = express.Router();
app.use('/', router);
app.set('view engine', 'ejs');
const port = 2020;
app.get('/' , (req, res) => {
res.render(path.join(__dirname+'/views/UiOfServer.ejs'), {flag: false, username: 'null'});
});
app.get('/click/' , (req, res) => {
res.render(path.join(__dirname+'/views/UiOfServer.ejs'), {flag: true, username: 'Hessam :) '})
}
app.listen(port, (err, res) => {
if(err){
console.log(`Server Error: ${err}`);
}
else{
console.log(`server started on ${port}`);
}
});
My question is pretty simple - why testcafe verifications ignore timeout, which I set in options?
For example next method, called for a page that will never be loaded, didnt wait 20 minutes until fail, it fails faster, ignoring timeout
waitForPageLoad: async (expectedUrl: string) => {
var getPageState: ClientFunction = ClientFunction(() => {
return new Promise(resolve => {
resolve(document.readyState as string);
});
}).with({ boundTestRun: testController });
await testController.expect(((await getPageState()) as string) === "complete").ok({ timeout: 1200000});
}
}
(method call and all methods above have 'await' keyword)
Is there any explanations for such thing?
You need to rewrite your assertions. See the following example based on the changeable document.a property:
index.html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<script>
document.a = '0';
window.setTimeout(() => { document.a = '1' }, 10000)
</script>
</body>
</html>
test.js
import { ClientFunction } from 'testcafe';
fixture `Fixture`
.page('./index.html');
test('test', async t => {
const getPageState = ClientFunction(() => {
return new Promise(resolve => {
resolve(document.a);
});
});
await t.expect(getPageState()).eql('1', { timeout: 1000 }); // it fails, increase the timeout (15000) to pass
});
I wanted to test deepstream with express.
Found this template https://github.com/deepstreamIO/ds-tutorial-express
But when I run it I get the error message:
Connection closed before receiving a handshake response
Why isn't this example working?
Server.js
var Deepstream = require( 'deepstream.io' );
var http = require( 'http' );
var express = require( 'express' );
var deepstream = new Deepstream();
var app = express();
var server = http.createServer(app);
app.get('/hello', function ( req, res ) {
res.send( 'Hello to you too!' );
})
deepstream.set( 'httpServer', server );
deepstream.start();
server.listen( 6020, function(){
console.log( 'HTTP server listening on 6020' );
});
index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Example Client</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">

</head>
<body>
<script>
var ds = deepstream( 'localhost:6020' );
ds.login( {}, function( success, errorEvent, errorMessage ) {
console.log( 'Logged in to deepstream' );
});
</script>
</body>

On the client, could you switch to this CDN link
<script src="https://cdnjs.cloudflare.com/ajax/libs/deepstream.io-client-js/1.1.1/deepstream.js"></script>
the rawgit one is pointing to the master branch which is already at 2.0 and incompatible with the 1.x server
I would like to use html2canvas but it is not clear enough how to use it in the documentation. What libraries I should include ? and then is this peace of code just what I need ? What about the proxy ? and How I could save the screen shot after it's taken ?
$('body').html2canvas();
var queue = html2canvas.Parse();
var canvas = html2canvas.Renderer(queue,{elements:{length:1}});
var img = canvas.toDataURL()
window.open(img);
For me, it was working this way:
$('#map').html2canvas({
onrendered: function( canvas ) {
var img = canvas.toDataURL()
window.open(img);
}
The current latest version works this way:
html2canvas($('#map'),
{
onrendered: function(canvas) {
cvs = canvas.toDataURL('image/png');
window.open(cvs)
}
});
Here's a minimal, complete example that shows how to convert the DOM to canvas with html2canvas, convert the canvas to base64, and finally trigger a download.
<!DOCTYPE html>
<html lang="en">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/1.4.1/html2canvas.min.js"></script>
</head>
<body>
<h1>Hello World</h1>
<script>
(async () => {
const canvas = await html2canvas(document.body);
const base64 = canvas.toDataURL();
const a = document.createElement("a");
a.href = base64;
a.download = "html2canvas-test.png";
a.click();
})();
</script>
</body>
</html>
I'm not sure what you mean about a proxy.
