We also offer several types of resources to help you get started. Read on to learn more about them!
Frameworks & SDKs
Bolt framework
Bolt is a framework that simplifies the Slack app development process. It's available in JavaScript, Python, and Java.
Bolt handles much of the foundational setup so you can focus on your app's functionality. Out of the box, Bolt includes:
- A basic web server to run your app on
- Authentication and installation handling for all the ins and outs of OAuth
- Simplified interfaces for all Slack APIs and app features
- Automatic token validation, retry, and rate-limiting logic
When we at Slack Developer Relations have to build an app, we go straight to Bolt. Click on your preferred flavor to get started.
