How To Make Sign In & Sign Up Form Using React JS
ReactJS is a popular JavaScript library for building user interfaces. In this article, we will learn how to create a sign in and sign up form using ReactJS. We will use ReactJS to build a simple login and registration form that allows users to sign in to an existing account or create a new account.
1. Create a React Component for the Sign In Form
The first step is to create a new React component for the sign in form. We can use the following code as a starting point for our sign in form component:
```javascript
import React, { useState } from 'react';
function SignInForm() {
const [email, setEmail] = useState('');
const [password, setPassword] = useState('');
const handleEmailChange = (e) => {
setEmail(e.target.value);
};
const handlePasswordChange = (e) => {
setPassword(e.target.value);
};
const handleSubmit = (e) => {
e.preventDefault();
// TODO: Add sign in logic here
};
return (
);
}
export default SignInForm;
```
2. Create a React Component for the Sign Up Form
Next, we need to create a new React component for the sign up form. We can use the following code as a starting point for our sign up form component:
```javascript
import React, { useState } from 'react';
function SignUpForm() {
const [email, setEmail] = useState('');
const [password, setPassword] = useState('');
const handleEmailChange = (e) => {
setEmail(e.target.value);
};
const handlePasswordChange = (e) => {
setPassword(e.target.value);
};
const handleSubmit = (e) => {
e.preventDefault();
// TODO: Add sign up logic here
};
return (
);
}
export default SignUpForm;
```
3. Create a React Component for the Login & Registration Form
Finally, we can create a new React component that combines the sign in and sign up forms into a single login and registration form. We can use the following code as a starting point for our login and registration form component:
```javascript
import React from 'react';
import SignInForm from './SignInForm';
import SignUpForm from './SignUpForm';
function LoginRegistrationForm() {
return (
Sign In
Sign Up
);
}
export default LoginRegistrationForm;
```
4. Use the Login & Registration Form Component in Your App
Now that we have created our login and registration form component, we can use it in our app by importing and rendering it in our main app component. Here’s an example of how we can use the login and registration form component in a simple React app:
```javascript
import React from 'react';
import LoginRegistrationForm from './LoginRegistrationForm';
function App() {
return (
Welcome to our app!
);
}
export default App;
```
Conclusion
In this article, we learned how to create a sign in and sign up form using ReactJS. We created separate components for the sign in and sign up forms, and then combined them into a single login and registration form component. We also learned how to use the login and registration form component in a simple React app. With this knowledge, you can now create your own login and registration forms using ReactJS.
