What is @bedrock-core?
@bedrock-core is a set of tools and libraries for creating Minecraft Bedrock content with JavaScript and TypeScript.
Use the build tools for a resource pack, a behavior pack, or a project containing many packs. Add the runtime libraries when your content needs cross-addon communication, persistent data or custom interfaces. Each part can be used independently.
Build your packs
Builder turns authored files into Minecraft packs. It bundles scripts, generates JSON from TypeScript, compiles translations and guides, and exports the completed packs. Watch mode rebuilds after changes and reuses results whose inputs are unchanged.
The CLI creates a project with the build commands and example files already connected. Choose a resource-only project, a scripting project or the full framework starter.
Connect addons
Minecraft runs each scripted behavior pack in its own JavaScript realm. Packs cannot share variables or import each other's runtime code.
Server supplies discovery, messages and shared state across those realms. Observable provides reactive values; db stores persistent documents. These libraries also work without the UI packages.
Add interfaces and content
UI builds screens from JSX. Navigation connects pages; ore-styled provides Minecraft-styled components. Config, guides and catalog add ready-made application flows.
Test the result
BDS runner runs GameTests on a headless Bedrock Dedicated Server and can optimize built packs for distribution.
