Hey there, fellow JavaScript devs! Ready to dive into the world of PagerDuty API integration? Let's get our hands dirty with some code and build a slick user-facing integration that'll keep your data in perfect sync.
First things first, you'll need an API key. Head over to your PagerDuty account settings and grab one. Once you've got it, let's set up authentication:
const axios = require('axios'); const pdClient = axios.create({ baseURL: 'https://api.pagerduty.com', headers: { 'Authorization': `Token token=${YOUR_API_KEY}`, 'Accept': 'application/vnd.pagerduty+json;version=2' } });
Now that we're in, let's fetch some incidents:
async function getIncidents() { try { const response = await pdClient.get('/incidents'); return response.data.incidents; } catch (error) { console.error('Error fetching incidents:', error); } }
Easy peasy, right? You can tweak this to grab user info or any other data you need.
Creating incidents is just as straightforward:
async function createIncident(title, description) { try { const response = await pdClient.post('/incidents', { incident: { type: 'incident', title, service: { id: 'YOUR_SERVICE_ID', type: 'service_reference' }, body: { type: 'incident_body', details: description } } }); return response.data.incident; } catch (error) { console.error('Error creating incident:', error); } }
Webhooks are your best friend for real-time updates. Set up an endpoint to handle PagerDuty's webhooks:
const express = require('express'); const app = express(); app.post('/webhook', express.json(), (req, res) => { const { messages } = req.body; messages.forEach(message => { // Handle the webhook payload console.log('Received webhook:', message); // Update your local data accordingly }); res.sendStatus(200); });
Always wrap your API calls in try/catch blocks. For rate limiting, consider using a library like bottleneck
:
const Bottleneck = require('bottleneck'); const limiter = new Bottleneck({ minTime: 100 // Ensures 100ms between requests }); const limitedPdClient = { get: limiter.wrap(pdClient.get), post: limiter.wrap(pdClient.post), // ... wrap other methods as needed };
There you have it! You're now armed with the knowledge to build a robust PagerDuty integration. Remember, the key to a great integration is keeping your local data in sync with PagerDuty's. Use webhooks for real-time updates, poll sparingly for everything else, and always handle errors gracefully.
Keep coding, stay curious, and may your incidents always resolve quickly! 🚀
