Reading and Writing Data Using the Uscreen API

Hey there, fellow JavaScript wizards! Ready to dive into the world of Uscreen API integration? Let's get our hands dirty with some data syncing magic for user-facing integrations. Buckle up!

The Uscreen API: Your New Best Friend

Uscreen's API is a powerful tool that lets you seamlessly integrate their video-on-demand platform with your own applications. Today, we're focusing on keeping your user data in perfect harmony across platforms. Trust me, your users will thank you for this smooth experience!

Authentication: The Key to the Kingdom

Before we start playing with data, we need to get past the bouncer. Here's how:

1. Grab your API credentials from the Uscreen dashboard.
2. Implement OAuth 2.0 flow (if that's your thing).

Here's a quick snippet to get you authenticated:

const getAccessToken = async () => {
  const response = await fetch('https://api.uscreen.io/oauth/token', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      client_id: 'YOUR_CLIENT_ID',
      client_secret: 'YOUR_CLIENT_SECRET',
      grant_type: 'client_credentials'
    })
  });
  const data = await response.json();
  return data.access_token;
};

Reading Data: Knowledge is Power

Fetching User Info

Let's grab some user data, shall we?

const getUserInfo = async (userId, accessToken) => {
  const response = await fetch(`https://api.uscreen.io/users/${userId}`, {
    headers: { 'Authorization': `Bearer ${accessToken}` }
  });
  return response.json();
};

Retrieving Content Metadata

Want to know what courses your users have access to? Here you go:

const getUserCourses = async (userId, accessToken) => {
  const response = await fetch(`https://api.uscreen.io/users/${userId}/courses`, {
    headers: { 'Authorization': `Bearer ${accessToken}` }
  });
  return response.json();
};

Writing Data: Make Your Mark

Updating User Profiles

Keep those profiles fresh:

const updateUserProfile = async (userId, accessToken, userData) => {
  const response = await fetch(`https://api.uscreen.io/users/${userId}`, {
    method: 'PATCH',
    headers: {
      'Authorization': `Bearer ${accessToken}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(userData)
  });
  return response.json();
};

Syncing User Progress

Don't lose that watch history:

const updateWatchProgress = async (userId, videoId, progress, accessToken) => {
  const response = await fetch(`https://api.uscreen.io/users/${userId}/progress`, {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${accessToken}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ video_id: videoId, progress })
  });
  return response.json();
};

Real-time Sync: Stay in the Loop

Uscreen doesn't support WebSockets? No problem! Let's set up a polling strategy:

const pollForUpdates = (userId, accessToken, interval = 5000) => {
  setInterval(async () => {
    const userData = await getUserInfo(userId, accessToken);
    // Update your local state with the fresh data
    updateLocalUserData(userData);
  }, interval);
};

Error Handling and Rate Limiting: Play Nice

Always be prepared for hiccups:

const apiCall = async (url, options, retries = 3) => {
  try {
    const response = await fetch(url, options);
    if (response.status === 429) {
      // Rate limited, wait and retry
      await new Promise(resolve => setTimeout(resolve, 1000));
      return apiCall(url, options, retries - 1);
    }
    return response.json();
  } catch (error) {
    if (retries > 0) {
      return apiCall(url, options, retries - 1);
    }
    throw error;
  }
};

Optimizing Performance: Speed Demon

Cache that data like a pro:

const cachedApiCall = (() => {
  const cache = new Map();
  return async (url, options, ttl = 60000) => {
    const cacheKey = `${url}${JSON.stringify(options)}`;
    if (cache.has(cacheKey)) {
      const { data, timestamp } = cache.get(cacheKey);
      if (Date.now() - timestamp < ttl) {
        return data;
      }
    }
    const data = await apiCall(url, options);
    cache.set(cacheKey, { data, timestamp: Date.now() });
    return data;
  };
})();

Wrapping Up

And there you have it, folks! You're now equipped to sync data like a boss using the Uscreen API. Remember to keep your code clean, your errors handled, and your users happy. For more in-depth info, check out the Uscreen API docs.

Now go forth and create some awesome integrations! 🚀
