Brazen Framework — IndexedDB Storage (developer guide)

Required for latest-stack apps that use IndexedDB persistence through Configuration Manager. One IndexedDB database per script (scriptPrefix with trailing dash stripped, e.g. brazen-r34xxx). Replaces localStorage/GM aggregate blobs for settings, tags, bookmarks, and download ledger.

Greasy Fork: reserved script id 583968 (unpublished — override locally for testing; see greasyfork-urls.md) · Requires: Utilities · Load before: Configuration Manager

Apps do not open the database directly. Use BrazenConfigurationManager.initialize(), getRepos(), and field APIs wired by the configuration manager.

When to use

Scenario	This module
New Brazen app with `async initialize()` + IDB persistence	Yes — `@require` before Configuration Manager
Legacy app on driver-only Configuration Manager 3.x	No — keep local/GM drivers until migrated
IDB unavailable (private mode, blocked storage)	CM sets `isIdbBlocked()`; persistence disabled, read-only UI

Quick start (script setup hook)

Seed script-specific data during first-time setup via setScriptSetup() on the configuration manager:

this._configurationManager.setScriptSetup(async (repos, cm) => {
  // Seed apis / tagTypes documents (example)
  let apis = await repos.storage.get(IDB_STORE_APIS, 'apis')
  if (!apis?.entries?.length) {
    await repos.storage.put(IDB_STORE_APIS, {
      id: 'apis',
      entries: [{ entryId: 1, name: 'gelbooru', label: 'Gelbooru' }],
    })
  }
})

Legacy local/GM data is imported automatically during setup by BrazenLegacyImporter when present.

Architecture

BrazenConfigurationManager
  └── BrazenStorageRepositories(scriptPrefix)
        ├── storage   → BrazenIndexedDBStorage (open, CRUD, health, zip)
        ├── meta      → MetaRepository (revision, setup lock, entryId counters)
        ├── settings  → SettingsRepository (non-tag field blobs)
        ├── tags      → TagRepository (registry + compile → tagRuleSets)
        ├── tagRules  → TagRuleRepository (row-per-rule by group)
        ├── bookmarks → BookmarkRepository
        └── ledger    → LedgerRepository

Database stores (schema v1)

Store	Shape	Role
`meta`	singleton	`revisionId`, setup flags, per-store `next*EntryId` counters, `compilePendingGroups`
`settings`	singleton document	Non-tag config fields (camelCase properties)
`apis`	singleton + `entries[]`	Site/API entities
`tagTypes`	singleton + `entries[]`	Canonical and alias tag types
`tags`	row per tag	Append-only registry (`name` immutable, case-sensitive)
`tagRules`	row per rule	Raw lines by `group` (blacklist, explored, …)
`tagRuleSets`	singleton	Compiled `rawLines` + `optimized` per tag-domain field
`bookmarks`	row per bookmark	Numeric `entryId`, `sortOrder`, label/tags/url
`ledgerEntries`	row per post id	Download duplicate ledger (`postId` unique)

Public surface (via Configuration Manager)

CM method	Role
`async initialize()`	Open DB, setup or normal phase, hydrate fields
`getRepos()`	`BrazenStorageRepositories` instance
`isStorageReady()` / `isIdbBlocked()` / `canPersist()`	Runtime gates
`toggleTagRule(fieldKey, tagName)`	Sidebar-style sole-tag toggle (writes `tagRules`, compiles)
`clearTagRules(fieldKey)`	Clear all rules in a tag group
`scheduleTagRuleCompile(groups)` / `ensureTagRuleSetsCompiled()`	Two-phase compile pipeline
`async save()` / `async backup()` / `async restore()`	Persistence + v3 zip bundle

Direct repository use (advanced, e.g. bookmark widget per-op):

let repos = this._configurationManager.getRepos()
await repos.bookmarks.add({ label: '…', tags: '…', url: '…', sortOrder: 0 })
let rows = await repos.bookmarks.listAll()

Tag rules pipeline

Write — tagRules rows (sidebar toggle, settings Apply, or legacy import).
Mark pending — affected groups added to meta.compilePendingGroups.
Compile — async/microtask: rules → tagRuleSets.*.optimized (compliance hot path reads compiled data only).
OR in new rules — not stored; legacy | lines are expanded on import via expandOrRuleLine().

Backup / restore (v3)

Export: zip bundle — one JSON file per store + manifest.json (backup version 3, defined in Configuration Manager as CONFIG_BACKUP_VERSION).
Import: v3 zip or JSON; v2/v1 flat backups still handled by Configuration Manager adapters.
Ledger restore: merge by postId (newer claimedAt wins).

Cross-tab sync

meta.revisionId bumps on writes. Configuration Manager listens to visibilitychange only (no BroadcastChannel) and reloads changed fields when revision differs.
