Migrate business logic

Most of your apps' business logic will work almost out-of-the-box. Depending on how your app was built, you need to do the following:

  1. Upgrade Actyx Pond
  2. Upgrade Actyx SDK (TypeScript)
  3. Ensure compatibility with an event log that identifies event streams by semantics

Actyx Pond​

Upgrade @actyx/pond to version 3. If you were using version 2, the business logic you wrote will still work.

Actyx SDK​

Replace @actyx/os-sdk with @actyx/sdk. As the @actyx/os-sdk was using the Events API v1 (based on semantics and name), this entails updating to the tag-based Events API v2 that was already used in the Actyx Pond 2.x.

Ensure compatibility with an old event log​

This step is only required if your apps need to be compatible with "old" data, i.e. events that were created directly through the Events HTTP API, or through the @actyx/os-sdk. To be compatible with these events, you can use the following tags:

  • semantics:*
  • fish_name:*
