Bolt v4

What's Changed

New Features

Support for Agents & Assistants is now available!

Bolt now offers a simple and intuitive way to create an Agent/Assistant using the new Assistant class. Simply include the required callbacks and add the assistant to your App instance. Get up and running even quicker with a working, out-of-the-box example that utilizes OpenAI here.

Breaking Changes

We have prepared a migration guide to help BoltJS consumers migrate their Bolt v3 apps to v4.

While a few breaking changes were introduced, we don't expect a majority of bolt v3 users to require changing their apps to upgrade to v4. More complex apps may need a few tweaks. TL;DR is: if your bolt v3 app is built with TypeScript, or uses the ExpressReceiver or the AwsLambdaReceiver, or your app used previously-deprecated types or functions, best to read the migration guide.

Middleware Type Changes

In bolt we have a set of Slack*MiddlewareArgs types: for events, shortcuts, commands, and so on. They 'wrap' the underlying event payloads with additional middleware-relevant bits like a next() method, a context object for devs to augment, and so on.

Many of these types, for example the SlackEventMiddlewareArgs type, previously used a conditional to sometimes define particular additional helper utilities on the middleware arguments. For example, the say utility, or tacking on a convenience message property for message-event-related payloads. This was problematic in practice in TypeScript situations, not just internally (this change fixes slackapi/bolt-js#2135) within the bolt codebase but for developers as well: when the payload was not of a type that required the extra utility, these properties would be required to exist on the middleware arguments but have a value of undefined. Those of us trying to build generic middleware utilities would have to deal with TS compilation errors and needing to liberally type-cast to avoid these conditional mismatches with undefined.

Instead, these MiddlewareArgs types now conditionally create a type intersection when appropriate in order to provide this conditional-utility-extension mechanism. In practice that looks something like:

type SomeMiddlewareArgs<EventType extends string = string> = {
  // some type in here
} & (EventType extends 'message'
  // If this is a message event, add a `message` property
  ? { message: EventFromType<EventType> }
  : unknown
)

With the above, now when a message payload is wrapped up into middleware arguments, it will contain an appropriate message property, whereas a non-message payload will be intersected with unknown - effectively a type "noop." No more e.g. say: undefined or message: undefined to deal with!

Other Breaking Changes

  • drops node v14 and v16 (are now EOL'ed)
  • express to v4->v5; ExpressReceiver users will be exposed to express v4 -> v5 breaking changes - fixes #2242
  • upgrades to @slack/socket-mode v2; SocketModeReceiver users who have attached custom event listeners to the public socketModeClient directly should read the v1 -> v2 migration guide in case the major upgrade could affect them - fixes #2225
