Release notes

0.15 (December 21, 2022)

API changes

  • New: chisel generate will generate a TypeScript client API that performs CRUD operations on entities while preserving typesafety. This API works with both web and nodejs where the standard web fetch API is available.

  • Bug fixes for the experimental TypeScript policy API.

0.14 (November 29, 2022)

API changes

  • Improvements to the query API to provide a MongoDB-like syntax for filtering entities with arbitrarily complex conditions. See the documentation for filter expressions.

  • Preview: Kafka event publishing support. See this example.

  • Preview: Policies written in TypeScript that allow you to specify rules for data creation, access, and filtering. See this blog for more information.

Internal changes

  • Deno upgraded to v1.26.2.


chiseld changes

  • Add a --secrets-polling-period-s TIME option to chiseld that can be used to reduce polling load on some systems.


chiseld changes

  • Don't fail server startup if the events directory is missing.

CLI changes

  • Make create-chiselstrike-app generate an events directory with .gitkeep.

0.13 (October 20, 2022)

API changes

  • BREAKING CHANGE: The endpoint API has been replaced with an improved routing API. The now a RouteMap API supports path-based parameters and allows you to specify routes by HTTP method and path. See the documentation for details.

  • Entities now support indirect entity relationship references using the Id type. Indirect references store the string ID of the referred entity and are not eagerly loaded.

  • Entities now support native JavaScript Date objects for properties.

  • Feature preview of TypeScript policies.

CLI changes

  • The create-chiselstrike-app tool now generates a Dockerfile for building Docker images of your ChiselStrike application. This is useful for deployment to Kubernetes,, and others services that accept containers.

Internal changes

  • Fixed Node.js compatibility issues. Many npm packages such as Axios resulted in errors such as Error: Dynamic require of "buffer" is not supported on ChiselStrike. The problem is now fixed with Deno's Node polyfills imported into the ChiselStrike runtime.

  • Deno upgraded to v1.25.4.

  • The runtime has had significant re-work under the hood, which is a prerequisite for improving stability and performance.
