The error view is not a constructor
in Node.js typically occurs when you are trying to instantiate or use something as a constructor (with new
), but the object you’re using isn’t a constructor function or class.
If you’re trying to use a view from a template engine (like EJS, Pug, etc.), ensure you’re importing it correctly. If you’re using something like express
with a view engine, it might look like this:
const express = require('express');
const app = express();
// Example for setting up EJS (view engine)
app.set('view engine', 'ejs');
// In a route handler, you might use it like:
app.get('/', (req, res) => {
res.render('index'); // Rendering a view called 'index.ejs'
});
Check if you’ve properly set the view engine and that you’re calling res.render()
correctly. If you accidentally call new
on the view
object or some module that doesn’t have a constructor, it could result in the error.
view
as a constructor when it’s notIf you’re trying to create an instance of a view directly with new
, but the module you’re using doesn’t support this, you’ll get the error.
For example:
const View = require('view'); // Wrong import
const myView = new View(); // Error: "view is not a constructor"
Solution: Make sure that the module you’re using actually supports the constructor pattern. If not, you should call its methods or use it the correct way (like the example with res.render()
above).

Can you share the part of your code where the error occurs? Specifically, the section where view
is being used.
Are you using a specific framework or library (e.g., Express, Sails.js)? If so, which version are you working with?
Did you follow any particular tutorial? Sharing the link or name of the resource can give more insight into your setup.
Which version of Node.js are you using?
If possible, share the complete error message and stack trace for better clarity.
