W-21523318 - Added --lwc-language flag with options: javascript, typescript - Added concise flag documentation in messages/project.md - Flag is optional and backward compatible - Validation ensures only valid values accepted
@W-21523380@ Add comprehensive NUT test suite for TypeScript project functionality covering all acceptance criteria: tsconfig.json with outDir: "dist" configuration, TypeScript dependencies in package.json, ESLint config using single @typescript-eslint/parser for both .js and .ts files, proper .forceignore/.gitignore exclusions for dist/ folder, and sfdx-project.json defaultLWCLanguage field. Includes backward compatibility tests confirming JavaScript projects remain unaffected when --lwc-language javascript is specified or flag is omitted. All 179 tests passing.
@W-21523390@ Add comprehensive documentation for TypeScript project creation covering architecture and usage patterns. Updates include TypeScript project generation examples, detailed explanation of dist/ folder strategy for local compilation vs. server-side type stripping, and enhanced CLI help text with flag descriptions. New "TypeScript Support for Lightning Web Components" section explains dual-mode approach: local type validation with npm run build (compiles to dist/) and server deployment of raw .ts files. Includes complete workflow example from project creation through deployment.
Add lwc-language flag to template:generate:project command snapshot to resolve deprecation policy check failures.

- Clarify that TypeScript applies to LWC, not entire project - Add explicit default: 'javascript' to lwc-language flag
Remove auto-generated command documentation bloat
- Remove dist/ folder references (architecture changed to erasableSyntaxOnly) - Fix camelCase: defaultLWCLanguage -> defaultLwcLanguage - Fix ESLint parser check: tsparser -> tseslint.parser - Update test assertions to match actual generated files Fixes 6 failing NUT tests in CI
…ly provided The default flag value shouldn't add the field to sfdx-project.json. Only add defaultLwcLanguage when user explicitly specifies --lwc-language. Fixes failing NUT test: 'should create default project without TypeScript files when no flag specified'

Remove the default lwc-language value. Set lwcLanguage only when users provide --lwc-language. Made-with: Cursor
