Replace Yarn with Bun as the package manager across the workspace. Update all scripts to use bun commands and replace lock files.
Implement a high-performance Rust CLI that parses TypeScript router files and generates tRPC AppRouter types. Includes: - Parser for @router, @query, @mutation decorators using swc - Zod schema extraction and flattening - Import resolution with barrel file support - TypeScript/JavaScript config file support (nestjs-trpc.config.ts) - Watch mode with file system events - JS bin wrapper for npm distribution
- Migrate github actions workflow to use bun - Add rust cli verification job (fmt, clippy, test, build) - Update husky hooks to use bun - Add bun installation instructions to READMEs - Add claude code instructions
Include a standard header comment in generated schema files to indicate they are auto-generated and should not be manually edited.
Remove TypeScript generators and move all schema generation to the Rust CLI. TRPCModule now handles runtime-only configuration while the CLI handles build-time generation with auto-discovery. Changes: - Deleted lib/generators/ directory entirely - Removed autoSchemaFile from TRPCModuleOptions - Added auto-discovery of TRPCModule from package.json - CLI defaults to ./@generated output - Changed --module flag to --entrypoint - Added parsers for module, context, and middleware metadata Breaking changes: - autoSchemaFile option removed from TRPCModule.forRoot() - Users must run 'npx nestjs-trpc generate' to generate schemas - No automatic generation on app startup

Flatten deeply nested code using let-else guards, helper function extraction, and early returns. Maximum nesting reduced to 2 levels following the never-nester principle. Files refactored: - config.rs: extract_default_export, parse_config_object - procedure.rs: extract_procedures_from_class - flatten.rs: flatten_call - router.rs: extract_router_from_item, extract_from_call_expr - middleware.rs: extract_from_module_item - context.rs: extract_from_module_item - decorator.rs: extract_from_call_expr, extract_arguments_from_object
Update gitignore to include @generated output directory. Remove config file and update middleware/service test data.
Remove CLI changelog and todo files that are no longer needed. Remove deprecated config directory with TypeScript config helpers.

Wow dude, you've been busy! |

Thanks 😅 There are more tweaks and checks I need to do before I release this, but I would expect this library to start getting updates pretty frequently from now on. I am also planning on merging the v2 repo @mguay22 have been maintaining to this one, and starting to chew through the issues. |
ESLint 9.x removed the useEslintrc and extensions options that Next.js 14.2.4 is trying to use. Downgraded to ESLint 8.57.1 to fix Vercel CI build failures. Also removed prettier/prettier rule from ESLint config as eslint-plugin-prettier is not installed.
