Step by Step Guide to Building a Uscreen API Integration in JS

Introduction

Hey there, fellow dev! Ready to dive into the world of Uscreen API integration? You're in for a treat. This guide will walk you through the process of building a robust integration using JavaScript. Uscreen's API is a powerful tool that'll let you tap into their video streaming platform, giving you the ability to manage users, content, and subscriptions programmatically. Let's get cracking!

Prerequisites

Before we jump in, make sure you've got these basics covered:

• Node.js installed (latest LTS version)
• A code editor of your choice (VS Code, Sublime, whatever floats your boat)
• A Uscreen account with API access
• Your Uscreen API key (keep it secret, keep it safe!)

Setting up the Development Environment

First things first, let's get our project set up:

mkdir uscreen-integration
cd uscreen-integration
npm init -y
npm install axios dotenv

Create a .env file in your project root and add your API key:

USCREEN_API_KEY=your_api_key_here

Authentication

Now, let's set up our authentication. Create an api.js file:

require('dotenv').config();
const axios = require('axios');

const api = axios.create({
  baseURL: 'https://api.uscreen.io/v1',
  headers: {
    'Authorization': `Bearer ${process.env.USCREEN_API_KEY}`,
    'Content-Type': 'application/json'
  }
});

module.exports = api;

Making API Requests

With our api.js set up, making requests is a breeze. Here's a quick example:

const api = require('./api');

async function getUsers() {
  try {
    const response = await api.get('/users');
    console.log(response.data);
  } catch (error) {
    console.error('Error fetching users:', error.response.data);
  }
}

getUsers();

Core API Functionalities

Let's implement some key functionalities:

Fetching User Data

async function getUserById(userId) {
  try {
    const response = await api.get(`/users/${userId}`);
    return response.data;
  } catch (error) {
    console.error(`Error fetching user ${userId}:`, error.response.data);
  }
}

Managing Video Content

async function getVideos() {
  try {
    const response = await api.get('/videos');
    return response.data;
  } catch (error) {
    console.error('Error fetching videos:', error.response.data);
  }
}

Handling Subscriptions

async function createSubscription(userId, planId) {
  try {
    const response = await api.post('/subscriptions', { user_id: userId, plan_id: planId });
    return response.data;
  } catch (error) {
    console.error('Error creating subscription:', error.response.data);
  }
}

Implementing Webhooks

If you're using webhooks, here's a quick Express server setup:

const express = require('express');
const app = express();

app.use(express.json());

app.post('/webhook', (req, res) => {
  const event = req.body;
  // Process the event
  console.log('Received webhook event:', event);
  res.sendStatus(200);
});

app.listen(3000, () => console.log('Webhook server running on port 3000'));

Error Handling and Logging

Implement a centralized error handler:

function handleApiError(error) {
  if (error.response) {
    console.error(`API Error: ${error.response.status} - ${error.response.data.message}`);
  } else if (error.request) {
    console.error('No response received from API');
  } else {
    console.error('Error setting up request:', error.message);
  }
}

Testing the Integration

Don't forget to test! Here's a simple test using Jest:

const api = require('./api');

jest.mock('./api');

test('getUsers returns user data', async () => {
  const mockUserData = [{ id: 1, name: 'Test User' }];
  api.get.mockResolvedValue({ data: mockUserData });

  const result = await getUsers();
  expect(result).toEqual(mockUserData);
});

Optimization and Best Practices

Remember to implement rate limiting and caching:

const rateLimit = require('express-rate-limit');
const cache = require('memory-cache');

const apiLimiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100
});

app.use('/api/', apiLimiter);

function cacheMiddleware(duration) {
  return (req, res, next) => {
    let key = '__express__' + req.originalUrl || req.url;
    let cachedBody = cache.get(key);
    if (cachedBody) {
      res.send(cachedBody);
    } else {
      res.sendResponse = res.send;
      res.send = (body) => {
        cache.put(key, body, duration * 1000);
        res.sendResponse(body);
      }
      next();
    }
  }
}

Deployment Considerations

When deploying, ensure you:

• Use environment variables for sensitive data
• Implement HTTPS
• Set up proper logging and monitoring
• Consider using a process manager like PM2

Conclusion

And there you have it! You've just built a solid Uscreen API integration. Remember, this is just the beginning - there's so much more you can do with the Uscreen API. Keep exploring, keep building, and most importantly, keep having fun with it!
