Introduction to Koder

Koder is a powerful platform for developers, offering a vast array of APIs to streamline and enhance development projects. In this blog post, we’ll delve into dozens of useful APIs, complete with code snippets and an exemplary app to demonstrate their capabilities.

User Authentication API

The User Authentication API allows developers to handle user login, registration, and session management effortlessly.

// Register a new user
const registerUser = async (userData) => {
  const response = await fetch('/api/register', {
    method: 'POST',
    headers: {'Content-Type': 'application/json'},
    body: JSON.stringify(userData),
  });
  return response.json();
};

// Login user
const loginUser = async (credentials) => {
  const response = await fetch('/api/login', {
    method: 'POST',
    headers: {'Content-Type': 'application/json'},
    body: JSON.stringify(credentials),
  });
  return response.json();
};

// Fetch user session
const getUserSession = async () => {
  const response = await fetch('/api/session');
  return response.json();
};

Data Storage API

With the Data Storage API, you can easily manage and retrieve data from the cloud.

// Save a record 
const saveRecord = async (recordData) => {
  const response = await fetch('/api/records', {
    method: 'POST',
    headers: {'Content-Type': 'application/json'},
    body: JSON.stringify(recordData),
  });
  return response.json();
};

// Retrieve a record 
const getRecord = async (id) => {
  const response = await fetch(`/api/records/${id}`);
  return response.json();
};

// Delete a record 
const deleteRecord = async (id) => {
  const response = await fetch(`/api/records/${id}`, {
    method: 'DELETE',
  });
  return response.json();
};

Notification API

The Notification API allows sending various types of notifications to users.

// Send an email notification
const sendEmailNotification = async (emailData) => {
  const response = await fetch('/api/notify/email', {
    method: 'POST',
    headers: {'Content-Type': 'application/json'},
    body: JSON.stringify(emailData),
  });
  return response.json();
};

// Send an SMS notification
const sendSMSNotification = async (smsData) => {
  const response = await fetch('/api/notify/sms', {
    method: 'POST',
    headers: {'Content-Type': 'application/json'},
    body: JSON.stringify(smsData),
  });
  return response.json();
};

Example Application

Let’s combine these APIs into a simple app that registers and logs in users, saves their records, and sends them notifications.

// User registration and login example
const handleRegistration = async () => {
  const userData = {username: 'example', password: 'password123'};
  const registeredUser = await registerUser(userData);
  console.log('User registered:', registeredUser);

  const loggedInUser = await loginUser(userData);
  console.log('User logged in:', loggedInUser);
};

// Save a user record and notify them
const notifyUser = async () => {
  const userRecord = {userId: 1, data: 'Sample Data'};
  const savedRecord = await saveRecord(userRecord);
  console.log('Record saved:', savedRecord);

  const emailData = {
    to: 'user@example.com',
    subject: 'Record Saved',
    message: 'Your record has been saved successfully.',
  };
  const notification = await sendEmailNotification(emailData);
  console.log('Email notification sent:', notification);
};

// Run the example
handleRegistration();
notifyUser();

By utilizing these APIs, developers can build robust and scalable applications with Koder.
