Two packages, imported as namespaces.

import * as Frond from "@frondruntime/core";
import * as FrondReact from "@frondruntime/react";

@frondruntime/core

Export	Purpose
`Frond.createRuntime(options?)`	Create a runtime. See Runtime and graph.
`Frond.createRuntimeClient(runtime)`	Build a client over a runtime host.
`Frond.Runtime`	Runtime types — `Runtime`, `RuntimeClient`, `RuntimeNodeHandle`, reads, snapshots, events.

Export	Purpose
`Frond.NodeBase`	Base class every node extends.
`Frond.resourceSpec` / `serviceSpec` / `facadeSpec` / `nodeSpec`	Spec constructors. See Kinds.
`Frond.tag(value)`	Create a node tag.
`Frond.dep(spec, args)`	Declare one dependency.
`Frond.dependencies(resolver)`	Declare a node’s dependency set.
`Frond.Args`	`Args.None` / `Args.none` for no-arg nodes.
`Frond.resultCommit(result, options)`	Attach validity/load metadata to a result.
`Frond.NodeSpec`, `Frond.NodeTag`, `Frond.Dep`, …	Authoring types.

Namespace	Contents
`Frond.Driver`	`Async`, `Effect`, `Acquire`, `Refresh`, `Release`, `Action`, `Live`. See Drivers.
`Frond.Key`	`singleton()`, `structure()`, `canonicalKey()`, `Singleton`, `MAX_CANONICAL_KEY_LENGTH`, key errors.
`Frond.Signals`	`channel()`, signal construction, runtime signal types.
`Frond.Diagnostics`	`createRuntimeReportSink`, `createErrorReport`, `projectError`, `serializeCauseChain`. See Error projection and Tags and diagnostics.
`Frond.Graph`	Graph types — `NodeId`, reads, snapshots, `EvictResult`, `ResultValidity`, failures.
`Frond.Events`	Runtime event types.
`Frond.MobX`	MobX interop helpers.

@frondruntime/react

Export	Purpose
`FrondReact.FrondProvider`	Put a runtime on context. See Provider.
`FrondReact.useRuntime` / `useRuntimeClient`	Reach the runtime imperatively.
`FrondReact.useNode`	Acquire and read with Suspense. See useNode.
`FrondReact.useNodeState`	Read with the lifecycle. See useNodeState.
`FrondReact.useNodes`	Read a map of nodes.
`FrondReact.useNodeControls` / `useNodesControls`	Refresh, evict, release. See useNodeControls.
`FrondReact.Preload`	Acquire before render. See Preload.
`FrondReact.getErrorReport`	Project a caught error into a displayable report.
`FrondReact.getErrorRecovery` / `isRecoverableNodeError`	Inspect and retry a readiness failure. See Suspense and errors.
