From ad48e7610163836fc7829fbf229f90878144f390 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 2 Dec 2025 19:03:18 +0000 Subject: [PATCH 01/22] feat(db): make indexing optional with separate entry point This POC explores making indexing a tree-shakeable opt-in feature to reduce default bundle size. Key changes: - Create new `@tanstack/db/indexing` entry point for BTreeIndex and related utils - Add index registry to replace hard-coded BTreeIndex defaults - Add dev-mode auto-detection for when indexes would help (collection size, slow queries) - Remove BTreeIndex value export from main entry (types still exported) Bundle size improvements when NOT using indexing: - Minified: ~15 KB saved (6.9%) - Gzipped: ~5.4 KB saved (8.5%) Usage after this change: ```ts // Option 1: Enable indexing globally import { enableIndexing } from '@tanstack/db/indexing' enableIndexing() // Option 2: Use explicit index type (best for tree-shaking) import { BTreeIndex } from '@tanstack/db/indexing' collection.createIndex((row) => row.userId, { indexType: BTreeIndex }) // Dev mode for index suggestions import { configureIndexDevMode } from '@tanstack/db' configureIndexDevMode({ enabled: true, collectionSizeThreshold: 100 }) ``` Note: Additional savings (~25KB more) possible by making index-optimization.ts lazy-loaded, but would require more extensive refactoring of change-events.ts and order-by.ts. --- packages/db/package.json | 10 ++ packages/db/src/collection/indexes.ts | 51 ++++-- packages/db/src/index.ts | 29 ++- packages/db/src/indexes/auto-index.ts | 45 ++++- packages/db/src/indexes/index-registry.ts | 206 ++++++++++++++++++++++ packages/db/src/indexing.ts | 81 +++++++++ packages/db/tests/test-setup.ts | 8 +- packages/db/vite.config.ts | 2 +- 8 files changed, 403 insertions(+), 29 deletions(-) create mode 100644 packages/db/src/indexes/index-registry.ts create mode 100644 packages/db/src/indexing.ts diff --git a/packages/db/package.json b/packages/db/package.json index 95a420c5b..017f671d9 100644 --- a/packages/db/package.json +++ b/packages/db/package.json @@ -36,6 +36,16 @@ "default": "./dist/cjs/index.cjs" } }, + "./indexing": { + "import": { + "types": "./dist/esm/indexing.d.ts", + "default": "./dist/esm/indexing.js" + }, + "require": { + "types": "./dist/cjs/indexing.d.cts", + "default": "./dist/cjs/indexing.cjs" + } + }, "./package.json": "./package.json" }, "sideEffects": false, diff --git a/packages/db/src/collection/indexes.ts b/packages/db/src/collection/indexes.ts index 037bd126c..1522e6c65 100644 --- a/packages/db/src/collection/indexes.ts +++ b/packages/db/src/collection/indexes.ts @@ -3,7 +3,7 @@ import { createSingleRowRefProxy, toExpression, } from '../query/builder/ref-proxy' -import { BTreeIndex } from '../indexes/btree-index' +import { getDefaultIndexType } from '../indexes/index-registry' import type { StandardSchemaV1 } from '@standard-schema/spec' import type { BaseIndex, IndexResolver } from '../indexes/base-index' import type { ChangeMessage } from '../types' @@ -38,8 +38,21 @@ export class CollectionIndexesManager< /** * Creates an index on a collection for faster queries. + * + * Note: If no indexType is specified, this will use the registered default + * index type.
