Alpha. APIs and on-disk formats can change without notice between releases. Pin exact versions and expect breaking changes.

The infrastructure type layer of Reventless — a spec-driven, event-sourced CQRS framework written in ReScript. This package defines the deploy-time infrastructure types and abstract Platform interface that are shared across storage/cloud adapters, so plugin-assembly code can be written once against provider-agnostic types and satisfied by any concrete adapter. It uses Pulumi types for deploy-time resource references. Modules are exposed under the ReventlessInfra namespace.

What it provides

ReScript modules, consumed by adding the package to your rescript.json dependencies.

Platform interface & adapters (types/, adapter/)

• Platform — the abstract factory interface for platform-agnostic component assembly. Plugin code takes a Platform.T as a functor argument; a concrete adapter (e.g. reventless-aws) supplies the implementation at the composition root.
• Adapter — deploy-time infrastructure primitives: resource (fields wrapped in Pulumi.Output.t), resolvedResource (runtime values), and resourceInfo describing a resource's structural role (storage keys, stream source, API resolver).
• ResourceNaming — provider-agnostic operations for validating and deriving URN-safe resource names.
• ExtensionMapping / ExtensionPointMapping — the action types that route commands and events between an extension and the extension point it wraps.
• Message, PluginExtensionPointSpec, NoEventMappings — supporting types for message identity and plugin/extension wiring.

Component types (components/)

Deploy-time outputs (infrastructure references) and runtime operations for each Reventless component kind — Component (the typed wrapper around a Pulumi ComponentResource), Plugin, Aggregate, ReadModel, EventLog / DcbEventLog, CommandTopic / EventTopic, CommandGenerator, EventCollector, EventMapper, QueryDb, Api, Task, ExtensionPoint / Extension, Scheduler, Heartbeat, and the DCB slices.

Where it fits

reventless-infra sits between the specification layer and the concrete adapters:

reventless-spec (specifications)
  ↓
reventless-infra (shared infrastructure types)  ← this package
  ↓
reventless-aws / reventless-postgres / reventless-local (storage & deployment adapters)

• It builds on @reventlessdev/reventless-spec for the domain contracts.
• Adapters such as @reventlessdev/reventless-aws provide the concrete Platform.T implementation these types describe.

You normally obtain reventless-infra transitively by scaffolding an app rather than installing it on its own.

Install

pnpm add @reventlessdev/reventless-infra

Then register it as a ReScript dependency in rescript.json:

{
  "dependencies": ["@reventlessdev/reventless-infra"]
}

Requires ReScript ^12.3.0 (peer dependency).
