Next.js binding for Userfront



Userfront Next.js

The Userfront Next.js binding allows you to quickly add pre-built signup, login, and password reset forms to your Next.js application.

This binding includes all methods from the Userfront core JS library.


You can find installation instructions for your account in the Toolkit section of the Userfront dashboard.

1. Install the @userfront/nextjs package with npm (or yarn)

npm install @userfront/nextjs --save

2. Initialize Userfront and any tools you want to use, then render them

import Userfront from "@userfront/nextjs";


const SignupForm = Userfront.build({
  toolId: "nkmbbm",

class Demo extends React.Component {
  render() {
    return <SignupForm />;

This example uses the following:

  • Account ID: demo1234
  • Tool ID: nkmbbm (signup form)

This will add a working signup form to your page:

Core JS methods

When you add the Userfront Next.js binding to your application, you can use any of the methods from the Userfront core JS library too.

Docs for the core JS methods are here: https://userfront.com/docs/js.html

Note that you do not need to import @userfront/core separately when using the React binding.
