Get URL value in static page in Express.js

I am beginner to node and express. In my current application the page is displaying using this code :

var app = express();
app.use(serveStatic('static', {'index': ['index.html']}));

and in static folder, there are there files:

css, index and a js file

Listening to 3000 port it is working normally.

But what if I want to access URL like this :

localhost:3000/name=someName

I want to use this name parameter in my js file which is available in static folder.
or suggest any other routing method to do that?

Solution

If you want to get the query parameters in your .js file it can be done. So the code would look like this:

Server (index.js)

"use strict";

var express = require("express");
var serveStatic = require('serve-static');

var app = express();
app.use(serveStatic('static', {'index': ['index.html']}));

app.listen(3000);

console.log("Static express server started");

HTML (/static/index.html)

<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="https://code.jquery.com/jquery-3.3.1.js"></script>
<script type="text/javascript" src="test.js"></script>
</head>
    <body onLoad="readParameters()">
        <div>
            <h3 id="1" >Loading..</h3>
        </div>
     </body>
</html>

Client side JavaScript (/static/test.js)

var readParameters = function()
{
    console.log('Getting parameters..');
    let params = (new URL(location)).searchParams;
    console.log('Query parameters: ', params.toString());

    var html = 'Query parameters: ';
    for (let p of params) {
      html += "<br/>" + p.toString();
    }

    $("#1").html(html);
}

Then you can test by entering:

http://localhost:3000/?test=value

Into your browser.

You should see:

Query parameters: test=value

on the index page.

The code tree should look like this:

root
¦   index.js
¦
+---static
        index.html
        test.js

3 Files:

/index.js (Node server side code)
/static/index.html (HTML)
/static/test.js (Test JavaScript file)
