Question 1

How do I create a modal with BlockKit in Python?

Accepted Answer

Use the Modal() class with chainable methods like .title() and .add_block(), as shown in the expense approval example—it automatically handles structure and validation, so you don't need to write JSON.

Question 2

Does BlockKit support all Slack block types like file inputs or date pickers?

Accepted Answer

The README shows common blocks like Section, Button, and Input, but check the official docs for full coverage; some newer or niche Slack blocks might require verification or direct JSON fallbacks.

Question 3

BlockKit vs writing raw JSON for Slack apps

Accepted Answer

BlockKit reduces errors and boosts productivity with validation and autocompletion, but raw JSON offers total control for unique cases. Choose BlockKit for team projects where consistency matters, and JSON for one-off scripts with specific needs.

Question 4

How to handle dynamic content like user data in BlockKit messages?

Accepted Answer

Integrate BlockKit's fluent API with Python string formatting or loops—for instance, use f-strings in Section text or iterate to add options, ensuring validation still catches issues before sending.

Question 5

Is BlockKit compatible with Slack's Bolt framework?

Accepted Answer

Yes, BlockKit can generate payloads for Bolt using .build(), but Bolt has its own UI builders; BlockKit is better if you prefer a standalone, type-safe approach without Bolt's overhead.

Question 6

What happens if Slack updates their API and BlockKit isn't updated?

Accepted Answer

You might encounter errors or missing features, as the library abstracts Slack's rules; monitor the GitHub repo for updates or be prepared to use raw JSON temporarily for new elements.
