Integrate "Change Password" Feature With Backend
Overview
In this article, we will guide you through the process of integrating the "Change Password" feature with the backend. This feature allows users to update their passwords securely and efficiently. We will cover the necessary steps to add a "Change Password" link on the Profile screen, review and adjust the existing Change Password page, and integrate the frontend form with the /api/auth/change-password endpoint.
Task 1: Add a “Change Password” Link on the Profile Screen
To begin, we need to add a "Change Password" link on the Profile screen. This link will direct users to the Change Password page where they can update their passwords.
Step 1: Create a New Component
First, let's create a new component for the "Change Password" link. We will call this component ChangePasswordLink.
// components/ChangePasswordLink.tsx
import React from 'react';
import { Link } from 'react-router-dom';
const ChangePasswordLink = () => {
return (
<div>
<Link to="/change-password">Change Password</Link>
</div>
);
};
export default ChangePasswordLink;
Step 2: Add the Link to the Profile Screen
Next, we need to add the "Change Password" link to the Profile screen. We will use the ChangePasswordLink component we created earlier.
// screens/Profile.tsx
import React from 'react';
import ChangePasswordLink from '../components/ChangePasswordLink';
const Profile = () => {
return (
<div>
<h1>Profile</h1>
<ChangePasswordLink />
</div>
);
};
export default Profile;
Task 2: Review and Adjust the Existing Change Password Page
The existing Change Password page is located in the app/auth/newPass.tsx file. We need to review and adjust this page as needed to ensure it meets the requirements for the "Change Password" feature.
Step 1: Review the Existing Page
Let's review the existing Change Password page to identify any issues or areas for improvement.
// app/auth/newPass.tsx
import React, { useState } from 'react';
const NewPass = () => {
const [currentPassword, setCurrentPassword] = useState('');
const [newPassword, setNewPassword] = useState('');
const [confirmPassword, setConfirmPassword] = useState('');
const handleSubmit = (event) => {
event.preventDefault();
// Submit the form data to the backend
};
return (
<div>
<h1>Change Password</h1>
<form onSubmit={handleSubmit}>
<label>
Current Password:
<input type="password" value={currentPassword} onChange={(event) => setCurrentPassword(event.target.value)} />
</label>
<label>
New Password:
<input type="password" value={newPassword} onChange={(event) => setNewPassword(event.target.value)} />
</label>
<label>
Confirm Password:
<input type="password" value={confirmPassword} onChange={(event) => setConfirmPassword(event.target.value)} />
</label>
button type="submit">Change Password</button>
</form>
</div>
);
};
export default NewPass;
Step 2: Adjust the Page as Needed
Based on our review, we may need to make adjustments to the page to ensure it meets the requirements for the "Change Password" feature. For example, we may need to add validation for the current password, new password, and confirm password fields.
// app/auth/newPass.tsx
import React, { useState } from 'react';
const NewPass = () => {
const [currentPassword, setCurrentPassword] = useState('');
const [newPassword, setNewPassword] = useState('');
const [confirmPassword, setConfirmPassword] = useState('');
const [errors, setErrors] = useState({});
const handleSubmit = (event) => {
event.preventDefault();
// Validate the form data
const validationErrors = validateForm(currentPassword, newPassword, confirmPassword);
if (validationErrors.length > 0) {
setErrors(validationErrors);
} else {
// Submit the form data to the backend
}
};
const validateForm = (currentPassword, newPassword, confirmPassword) => {
const errors = [];
if (currentPassword === '') {
errors.push('Current password is required');
}
if (newPassword === '') {
errors.push('New password is required');
}
if (confirmPassword === '') {
errors.push('Confirm password is required');
}
if (newPassword !== confirmPassword) {
errors.push('Passwords do not match');
}
return errors;
};
return (
<div>
<h1>Change Password</h1>
<form onSubmit={handleSubmit}>
<label>
Current Password:
<input type="password" value={currentPassword} onChange={(event) => setCurrentPassword(event.target.value)} />
{errors.currentPassword && <div style={{ color: 'red' }}>{errors.currentPassword}</div>}
</label>
<label>
New Password:
<input type="password" value={newPassword} onChange={(event) => setNewPassword(event.target.value)} />
{errors.newPassword && <div style={{ color: 'red' }}>{errors.newPassword}</div>}
</label>
<label>
Confirm Password:
<input type="password" value={confirmPassword} onChange={(event) => setConfirmPassword(event.target.value)} />
{errors.confirmPassword && <div style={{ color: 'red' }}>{errors.confirmPassword}</div>}
</label>
<button type="submit">Change Password</button>
</form>
</div>
);
};
export default NewPass;
Task 3: Integrate the Frontend Form with the /api/auth/change-password Endpoint
Now that we have reviewed and adjusted the existing Change Password page, we need to integrate the frontend form with the /api/auth/change-password endpoint.
Step 1: Create a New API Client
First, let's create a new API client to interact with the /api/auth/change-password endpoint.
// api/client.ts
import axios from 'axios';
const apiClient = axios.create({
baseURL: 'https://cloud.kbrw.pl/api',
export default apiClient;
Step 2: Create a New API Service
Next, let's create a new API service to handle the logic for the "Change Password" feature.
// api/services/changePassword.ts
import apiClient from '../api/client';
const changePassword = async (currentPassword, newPassword) => {
try {
const response = await apiClient.post('/auth/change-password', {
currentPassword,
newPassword,
});
return response.data;
} catch (error) {
throw error;
}
};
export default changePassword;
Step 3: Integrate the Frontend Form with the API Service
Finally, let's integrate the frontend form with the API service.
// app/auth/newPass.tsx
import React, { useState } from 'react';
import changePassword from '../api/services/changePassword';
const NewPass = () => {
const [currentPassword, setCurrentPassword] = useState('');
const [newPassword, setNewPassword] = useState('');
const [confirmPassword, setConfirmPassword] = useState('');
const [errors, setErrors] = useState({});
const handleSubmit = async (event) => {
event.preventDefault();
// Validate the form data
const validationErrors = validateForm(currentPassword, newPassword, confirmPassword);
if (validationErrors.length > 0) {
setErrors(validationErrors);
} else {
try {
const response = await changePassword(currentPassword, newPassword);
console.log(response);
} catch (error) {
setErrors({ error: 'Failed to change password' });
}
}
};
const validateForm = (currentPassword, newPassword, confirmPassword) => {
const errors = [];
if (currentPassword === '') {
errors.push('Current password is required');
}
if (newPassword === '') {
errors.push('New password is required');
}
if (confirmPassword === '') {
errors.push('Confirm password is required');
}
if (newPassword !== confirmPassword) {
errors.push('Passwords do not match');
}
return errors;
};
return (
<div>
<h1>Change Password</h1>
<form onSubmit={handleSubmit}>
<label>
Current Password:
<input type="password" value={currentPassword} onChange={(event) => setCurrentPassword(event.target.value)} />
{errors.currentPassword && <div style={{ color: 'red' }}>{errors.currentPassword}</div>}
</label>
<label>
New Password:
<input type="password" value={newPassword} onChange={(event) => setNewPassword(event.target.value)} />
{errors.newPassword && <div style={{ color: 'red' }}>{errors.newPassword}</div>}
</label>
<label>
Confirm Password:
<input type="password" value={confirmPassword} onChange={(event) => setConfirmPassword(event.target.value)} />
{errors.confirmPassword && <div style={{ color: 'red' }}>{errors.confirmPassword}</div>}
</label>
<button type="submit">Change Password</button>
</form>
</div>
);
};
export default NewPass<br/>
