generators

Pure code generators that turn a resolved feature config and parsed contract into staged output files.

API

Export	Purpose
`generateShell`	Stages the self-contained host connector package (entry, `package.json`, README, metadata).
`generateMetadata`	Stages the connector's `metadata.json` with a version-stamped, embedded contract.
`generateFeatureModule`	Stages the write-once feature integration module (`src/hyperfrontend.feature.ts`).
`generateContractTypes`	Bridges a `.json` contract to a sibling `.d.ts` of literal-type unions.

Usage

import { createTree } from '@hyperfrontend/project-scope/vfs'
import { generateShell } from '@hyperfrontend/features/generators'

const tree = createTree('/tmp/clock-shell')
generateShell({ name: 'clock', version: '1.0.0', contract: './clock.contract.json', url: '/clock' }, contract, tree)

API Reference

ƒ Functions

§function

generateContractTypes(config: ResolvedFeatureConfig, contract: FeatureContract, tree: Tree): void

Stages a .d.ts of literal-type declarations beside a JSON contract.
Only .json contracts need this bridge; .ts as const contracts derive types via typeof and are skipped (no file is staged). Pure: stages only into tree.

Parameters

Name	Type	Description
§config	`ResolvedFeatureConfig`	The resolved feature config naming the feature and contract path.
§contract	`FeatureContract`	The validated contract whose literals are preserved.
§tree	`Tree`	The VFS tree the declaration file is staged into.

Example

Bridging a JSON contract to literal types

generateContractTypes({ name: 'clock', version: '1.0.0', contract: './clock.contract.json', url: '/clock' }, contract, tree)

§function

generateFeatureModule(config: ResolvedFeatureConfig, contract: FeatureContract, tree: Tree): void

Stages the feature integration module into the consumer app (write-once).
Emits src/hyperfrontend.feature.ts with one feature.on stub per accepted action and a commented feature.send example per emitted action. Uses Mode.SkipIfExists, so a re-run never clobbers the author's edits. The CLI owns inserting the marker-guarded import into the entry file.

Parameters

Name	Type	Description
§config	`ResolvedFeatureConfig`	The resolved feature config.
§contract	`FeatureContract`	The validated feature contract driving the scaffolded stubs.
§tree	`Tree`	The VFS tree the integration module is staged into.

Example

Scaffolding the integration module for the clock feature

generateFeatureModule({ name: 'clock', version: '1.0.0', contract: './clock.contract.json', url: '/clock' }, contract, tree)

§function

generateMetadata(config: ResolvedFeatureConfig, contract: FeatureContract, tree: Tree): void

Stages the connector's metadata.json describing the feature and its contract.
Stamps a canonical version string via @hyperfrontend/versioning and embeds the contract so humans and the registry can inspect the feature without unpacking the bundle.

Parameters

Name	Type	Description
§config	`ResolvedFeatureConfig`	The resolved feature config supplying name, version, and URL.
§contract	`FeatureContract`	The validated contract embedded for inspection.
§tree	`Tree`	The VFS tree the metadata file is staged into.

Example

Staging metadata for the clock feature

generateMetadata({ name: 'clock', version: '1.0.0', contract: './clock.contract.json', url: '/clock' }, contract, tree)

§function

generateShell(config: ResolvedFeatureConfig, contract: FeatureContract, tree: Tree): void

Stages the complete host connector package into the supplied VFS tree.
Emits the entry source, source-level package.json, README.md, and (via generateMetadata) metadata.json. Pure: stages only into tree — the CLI owns temp-dir creation, bundling, and commit.

Parameters

Name	Type	Description
§config	`ResolvedFeatureConfig`	The resolved feature config.
§contract	`FeatureContract`	The validated feature contract, inlined into the connector.
§tree	`Tree`	The VFS tree the connector files are staged into.

Example

Staging a connector for the clock feature

generateShell({ name: 'clock', version: '1.0.0', contract: './clock.contract.json', url: '/clock' }, contract, tree)
