+pnpx nx build:transpile devextreme     # Transpile source code
+pnpx nx bundle:debug devextreme        # Create debug bundle

+
+**Build with testing configuration (for CI):**
+```bash
+pnpx nx build devextreme -c=testing
+```
 
 **Important environment variables:**
 - `DEVEXTREME_TEST_CI=true` - Enables test mode (skips building npm package)
 - `BUILD_ESM_PACKAGE=true` - Builds ESM modules (skips building npm package)
 - `BUILD_TESTCAFE=true` - Builds for TestCafe tests
 - `BUILD_TEST_INTERNAL_PACKAGE=true` - Builds internal test package
 
+## Custom Nx Executors (nx-infra-plugin)
+
+The `packages/nx-infra-plugin` provides custom Nx executors for build automation:
+
+| Executor | Description |
+|----------|-------------|
+| `add-license-headers` | Adds DevExtreme license headers to compiled files with version information |
+| `babel-transform` | Transforms JS/TS files using Babel with configurable presets, debug block removal, and extension renaming |
+| `build-angular-library` | Builds Angular libraries using ng-packagr programmatically |
+| `build-typescript` | Compiles TypeScript to CJS or ESM modules with configurable output format, tsconfig, and path alias resolution |
+| `bundle` | Bundles JavaScript files using webpack with debug or production mode, supporting multiple entry points and license validation |
+| `clean` | Removes directories and files with support for exclusion patterns |
+| `concatenate-files` | Concatenates files with optional content extraction via regex, header/footer, and find/replace transforms |
+| `copy-files` | Copies files and directories to specified destinations with glob pattern support |
+| `create-dual-mode-manifest` | Generates package.json files for dual-mode (ESM + CJS) support with main, module, typings, and sideEffects |
+| `generate-component-names` | Generates TypeScript file with component name constants for test automation |
+| `generate-components` | Generates framework components (React/Vue/Angular) from DevExtreme metadata |
+| `karma-multi-env` | Runs Karma tests across multiple Angular environments (client, server, hydration) |
+| `localization` | Generates CLDR data and compiles localization message files from JSON to JavaScript |
+| `pack-npm` | Creates npm packages using `pnpm pack` for distribution |
+| `prepare-package-json` | Creates distribution-ready package.json with cleaned dependencies for npm publishing |
+| `prepare-submodules` | Creates package.json entry points for submodule exports |
+
+**Example executor usage in project.json:**
+```json
+{
+  "build:localization:generate": {
+    "executor": "devextreme-nx-infra-plugin:localization",
+    "options": {
+      "messagesDir": "./js/localization/messages",
+      "cldrDataOutputDir": "./js/__internal/core/localization/cldr-data"

 ## Key Facts
 
 - **Nx is used for task orchestration** - prefer `pnpx nx` commands over direct npm scripts
+- **Custom Nx executors** - `devextreme-nx-infra-plugin` provides specialized executors for localization, file operations, and build tasks
 - **Frozen lockfile is mandatory** - CI will fail without it
 - **Build artifacts are in gitignore** - never commit `artifacts/` directories
 - **Wrappers are generated** - modify generators, not generated code
 - **Multiple test frameworks** - QUnit (legacy), Jest (new), TestCafe (E2E)
 - **Monorepo uses pnpm workspaces** - dependencies are hoisted
 - **CI uses custom runners** - `devextreme-shr2` for most jobs, `ubuntu-latest` for some
 - **Timeouts are strict** - optimize for speed, use caching
+- **Granular build caching** - individual build steps have proper Nx caching for faster rebuilds
