The TypeScript runtime

@datalayer/reactor implements:

  • definePlugin, defineLazyPlugin and configurePlugin
  • defineExtension, to group plugins into one installable capability
  • dependencies, peerDependencies, conflictsWith
  • ordered phases: init → build → register → afterRegistration
  • runtime lifecycle control: start, stop, enable, disable
  • contribution points and contributions: defineContributionPoint, contribution, ctx.contribute, reactor.getContributions
  • activation and deactivation events: activationEvents, deactivationEvents, reactor.fire, reactor.deactivate, onContributionPoint, onView, onCommand
  • signal primitives for reactive plugin outputs: signal, computed, effect, batch, untracked, namedSignals, watchedSignal

Core vs React split​

  • Core runtime exports from @datalayer/reactor
  • React bindings export from @datalayer/reactor/react

The split is what lets the same platform run in a Node service or a CLI without React being installed. See React bindings for the second half.
