blueprint-data-api - Verso Blueprint JavaScript API

Generated-data API for custom Blueprint clients.

This module is emitted as -verso-data/api/data.mjs in generated sites. It exposes manifest, HTML cache, preview-key, and URL helpers without importing DOM rendering code or installing any page-global render hook.

Use this module for audits, dashboards, migration tools, or Node-like clients that own their UI and only need generated data. The manifest is the semantic contract: labels, facets, generated links, external markup metadata, dependency metadata, status metadata, and graph records. The HTML cache is rendered presentation data; do not parse it to recover semantics.

Browser clients that need to insert Blueprint content should use api/preview.mjs instead. Graph dashboards may use this module for manifest data, but graph-specific helpers are collected in api/graph.mjs.

Members

(static, constant) ready :Promise.<BlueprintDataApi>

Description:

Promise for the default data API instance.

Promise for the default data API instance.

Type:

Promise.<BlueprintDataApi>

Methods

(static) createPreviewData(optionsopt) → {BlueprintDataApi}

Description:

Create an isolated data API instance.

Use this when a custom client wants explicit loaders and cache state instead of the module-level default singleton.

Example

// Import the data-only API when no DOM rendering is needed.
import { createPreviewData } from "./-verso-data/api/data.mjs";

// Create an isolated data loader for this client.
const data = createPreviewData();

// Build the same manifest/cache key Blueprint uses for statement previews.
const key = data.statementPreviewKey("main_theorem");

// Read one semantic manifest entry by key.
const entry = await data.loadManifestEntry(key);

if (entry) {
  console.log(entry.href, entry.label, entry.facet);
}

Parameters:

Name	Type	Attributes	Description
`options`	BlueprintDataApiOptions	<optional>	Loader and generated-data base URL options.

Returns:

Data API instance.

Type: BlueprintDataApi

(static) currentDataApi() → {BlueprintDataApi|null}

Description:

Return the module-level data API if it has already been created.

Returns:

Type: BlueprintDataApi | null

(static) dataApiModuleUrl(baseUrlopt) → {string}

Description:

Resolve the generated data API module URL.

Parameters:

`baseUrl`	string	<optional>	Base URL. Defaults to this module URL.

Returns:

Type: string

(static) getDataApi() → {Promise.<BlueprintDataApi>}

Description:

Return the module-level data API, creating it on first use.

Returns:

Type: Promise.<BlueprintDataApi>

(static) graphApiModuleUrl(baseUrlopt) → {string}

Description:

Resolve the generated graph API module URL.

Parameters:

Name	Type	Attributes	Description

Returns:

Type: string

(static) loadHtmlCache(optionsopt) → {Promise.<Map.<string, BlueprintHtmlCacheEntry>>}

Description:

Load and decode the rendered HTML fragment cache.

The cache contains rendered presentation fragments keyed like the manifest. Insert or display these fragments as HTML; do not parse them to rediscover semantic data that already lives in the manifest.

Parameters:

Name	Type	Attributes	Description
`options`	BlueprintDataApiOptions	<optional>	Optional per-call load overrides.

Returns:

Type: Promise.<Map.<string, BlueprintHtmlCacheEntry>>

(static) loadHtmlCacheEntry(key, optionsopt) → {Promise.<(BlueprintHtmlCacheEntry|null)>}

Description:

Load a single HTML-cache entry by key.

Parameters:

Name	Type	Attributes	Description
`key`	string		HTML cache key.
`options`	BlueprintDataApiOptions	<optional>	Optional per-call load overrides.

Returns:

Type: Promise.<(BlueprintHtmlCacheEntry|null)>

(static) loadManifest(optionsopt) → {Promise.<Map.<string, BlueprintManifestEntry>>}

Description:

Load and decode the Blueprint manifest.

The manifest is the semantic data source for generated Blueprint sites. Use it for labels, generated links, external markup metadata, graph records, and other structured facts.

Parameters:

Name	Type	Attributes	Description
`options`	BlueprintDataApiOptions	<optional>	Optional per-call load overrides.

Returns:

Type: Promise.<Map.<string, BlueprintManifestEntry>>

(static) loadManifestEntry(key, optionsopt) → {Promise.<(BlueprintManifestEntry|null)>}

Description:

Load a single manifest entry by key.

Parameters:

Name	Type	Attributes	Description
