Reading and Writing Data Using the OneLogin API

Hey there, fellow JavaScript devs! Ready to dive into the world of OneLogin API integration? Let's get our hands dirty with some data syncing for user-facing integrations. Buckle up, because we're about to make your life a whole lot easier.

Setting Up the OneLogin API Client

First things first, let's get that API client up and running. It's as easy as pie:

npm install onelogin-node-sdk

Now, let's configure our client:

const { OneLoginClient } = require('onelogin-node-sdk');

const client = new OneLoginClient({
  clientId: 'YOUR_CLIENT_ID',
  clientSecret: 'YOUR_CLIENT_SECRET',
  region: 'us'
});

Reading User Data

Time to fetch some user profiles! Here's how you can grab that sweet, sweet data:

async function getUserProfile(userId) {
  try {
    const user = await client.users.getOne(userId);
    console.log(user);
  } catch (error) {
    console.error('Oops! Something went wrong:', error);
  }
}

Need to handle pagination? No sweat:

async function getAllUsers() {
  let users = [];
  let page = 1;
  let hasMore = true;

  while (hasMore) {
    const response = await client.users.getAll({ page });
    users = users.concat(response.data);
    hasMore = response.pagination.next_link !== null;
    page++;
  }

  return users;
}

Writing User Data

Creating a new user? Easy peasy:

async function createUser(userData) {
  try {
    const newUser = await client.users.create(userData);
    console.log('User created:', newUser);
  } catch (error) {
    console.error('User creation failed:', error);
  }
}

Updating user info? We've got you covered:

async function updateUser(userId, updatedData) {
  try {
    const updatedUser = await client.users.update(userId, updatedData);
    console.log('User updated:', updatedUser);
  } catch (error) {
    console.error('Update failed:', error);
  }
}

Syncing Data

Let's implement a basic sync function:

async function syncUserData(localUsers, remoteUsers) {
  for (const localUser of localUsers) {
    const remoteUser = remoteUsers.find(u => u.email === localUser.email);
    
    if (remoteUser) {
      // Update existing user
      await updateUser(remoteUser.id, localUser);
    } else {
      // Create new user
      await createUser(localUser);
    }
  }
}

Webhooks for Real-time Updates

OneLogin's webhooks are your best friend for real-time updates. Here's a simple Express.js webhook handler:

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

app.post('/webhook', express.json(), (req, res) => {
  const event = req.body;
  
  switch (event.type) {
    case 'user.created':
      console.log('New user created:', event.data);
      break;
    case 'user.updated':
      console.log('User updated:', event.data);
      break;
    // Handle other event types
  }

  res.sendStatus(200);
});

Error Handling and Best Practices

Always wrap your API calls in try-catch blocks. And don't forget about rate limiting:

const { RateLimiter } = require('limiter');

const limiter = new RateLimiter({ tokensPerInterval: 5, interval: 'second' });

async function rateLimitedApiCall(apiFunction) {
  await limiter.removeTokens(1);
  return apiFunction();
}

Wrapping Up

There you have it, folks! You're now armed with the knowledge to read and write data like a pro using the OneLogin API. Remember, practice makes perfect, so don't be afraid to experiment and push the boundaries.
