Reading and Writing Data Using the Process Street API

Hey there, fellow JavaScript devs! Ready to dive into the world of Process Street API integration? Let's get our hands dirty with some code and learn how to sync data like pros.

Authentication: Your Key to the Kingdom

First things first, you'll need to grab your API credentials. Head over to your Process Street account settings and generate those keys. Once you've got them, let's set up authentication in JavaScript:

const axios = require('axios');

const api = axios.create({
  baseURL: 'https://api.process.st/api/v1',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY_HERE'
  }
});

Easy peasy, right? Now we're ready to rock and roll!

Reading Data: Fetching the Good Stuff

Time to pull some data from Process Street. We'll focus on fetching workflows, runs, and task details. Check this out:

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

async function getTaskDetails(taskId) {
  try {
    const response = await api.get(`/tasks/${taskId}`);
    return response.data;
  } catch (error) {
    console.error('Error fetching task details:', error);
  }
}

Writing Data: Making Your Mark

Now let's flip the script and write some data. We'll create new workflow runs, update task statuses, and throw in some comments for good measure:

async function createWorkflowRun(workflowId, data) {
  try {
    const response = await api.post(`/workflows/${workflowId}/runs`, data);
    return response.data;
  } catch (error) {
    console.error('Error creating workflow run:', error);
  }
}

async function updateTaskStatus(taskId, status) {
  try {
    const response = await api.patch(`/tasks/${taskId}`, { status });
    return response.data;
  } catch (error) {
    console.error('Error updating task status:', error);
  }
}

Syncing Data: Keeping It Fresh

Real-time updates are where it's at! Let's set up a webhook listener to keep our data in sync:

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

app.post('/webhook', express.json(), (req, res) => {
  const event = req.body;
  console.log('Received webhook event:', event);
  // Handle the event based on its type
  // Update your local data accordingly
  res.sendStatus(200);
});

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

Pro tip: Implement efficient caching strategies to minimize API calls and keep your app snappy!

Error Handling and Rate Limiting: Stay Cool Under Pressure

Don't let errors throw you off your game. Here's a quick example of how to handle errors and implement retry logic:

async function makeApiCall(fn, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (error) {
      if (error.response && error.response.status === 429) {
        // Rate limited, wait and retry
        await new Promise(resolve => setTimeout(resolve, 1000 * (i + 1)));
      } else if (i === maxRetries - 1) {
        throw error;
      }
    }
  }
}

Best Practices: Level Up Your Integration Game

1. Optimize API calls by batching requests when possible.
2. Keep sensitive data secure - never expose your API key in client-side code.
3. Maintain data consistency by implementing proper error handling and rollback mechanisms.

Wrapping Up

And there you have it, folks! You're now armed with the knowledge to build a killer Process Street API integration. Remember, practice makes perfect, so don't be afraid to experiment and push the boundaries of what you can do.

Happy coding, and may your integrations be ever smooth and your data always in sync! 🚀
