Express res.sendFile() with Query String

I have successfully implemented serving static files using res.sendFile() but it doesn't works if I add some querystring.

E.g. the below code works absolutely fine.

res.sendFile(path.join(__dirname, '../public', '/index.html'));

But if I do this, it fails

res.sendFile(path.join(__dirname, '../public', '/index.html?id=' +;

res.sendFile(path.join(__dirname, '../public', '/index.html?id=123'));

Then I get the below error

ENOENT, stat '/Users/krishnandu/Documents/Project/public/index.html?id=123'


Error: ENOENT, stat '/Users/krishnandu/Documents/Project/public/index.html?id=123'
at Error (native)

You cannot pass query string parameters with res.sendFile(). You have to specify the file path as the 1st parameter in res.sendFile()

Syntax is :

res.sendFile(path [, options] [, fn])

So what you can do is,

  1. Use the query string with a route, say route1 (refer the below code)

  2. Inside the GET method of route1, use res.sendFile()

      res.sendFile(path.join(__dirname, '../public', '/index.html'));

See also Express API documentation of res.sendFile and res.redirect.
