Question 1

How to set up OAuth with Node Slack SDK?

Accepted Answer

Use the @slack/oauth package to handle both V2 and V1 OAuth flows. Configure redirect URIs in your Slack app settings and follow the documentation for authentication steps, starting with the Getting Started tutorial for guidance.

Question 2

Node Slack SDK or bolt-js: which should I use for a Slack bot?

Accepted Answer

Node Slack SDK provides low-level API access for custom integrations, while bolt-js is a framework built on it for easier event handling. Choose bolt-js for rapid bot development with middleware, or the SDK for fine-grained control over API calls.

Question 3

How to listen for Slack events with Node SDK?

Accepted Answer

For basic listening, use @slack/socket-mode with WebSocket connections. However, the README references Bolt for JavaScript for full event processing, so consider integrating Bolt for structured event handling and actions.

Question 4

Best practices for error handling in Node Slack SDK?

Accepted Answer

Wrap Web API calls in try-catch blocks, as shown in the posting message example. Handle rate limits by implementing retries and check response statuses, following Slack's API guidelines for robust error management.

Question 5

Does Node Slack SDK support Slack's Block Kit?

Accepted Answer

Yes, through the Web API's chat.postMessage method, you can include blocks for rich messages. Use the Block Kit Builder playground to design layouts, as recommended in the README's tip for prototyping.

Question 6

How to test a Slack app built with Node SDK locally?

Accepted Answer

Use tools like ngrok to expose local endpoints for OAuth callbacks. Socket Mode allows development without public URLs, but testing interactive components may require additional setup with event simulation.
