tRPC

TSRX (TypeScript Render Extensions) is a TypeScript language extension for building declarative user interfaces in `.tsrx` files. It keeps TypeScript setup code, JSX-shaped markup, template-native `@if`, `@for`, `@switch`, and `@try` control flow, and component-scoped `<style>` blocks in one lexical scope, then parses the source into a framework-neutral AST for a selected target compiler. Supported targets include React, Preact, Solid, Vue, Ripple, and Octane; the project also provides compiler and runtime helpers, build integrations, language-server support, and integrations for TypeScript, Prettier, ESLint, VS Code, Zed, Neovim, IntelliJ, and Sublime Text. TSRX is in active beta development and is released under the MIT License. It was created by Dominic Gannaway.

tsrs is a Rust-based drop-in replacement for the TypeScript 7 compiler and language server. It aims for full TypeScript conformance while using less memory and checking types faster, and can be run through its CLI with pnpm or used through Node APIs. The project also provides WebAssembly support through @tsrs/wasm for WASI, Node, and browser environments. It is licensed under Apache-2.0 and is not affiliated with or endorsed by Microsoft.

gRPC is an open-source Remote Procedure Call framework for connecting services across environments and data centers. It uses Protocol Buffers for service definitions and binary serialization, then generates client and server stubs for multiple languages and platforms. The framework supports HTTP/2-based transport, bidirectional streaming, pluggable load balancing, tracing, health checking, and authentication, and can also connect devices, mobile applications, and browsers to backend services. gRPC is a CNCF incubation project.

TanStack Router is an open-source web application routing tool in the TanStack stack, used to handle navigation in web applications. TanStack describes its tools as headless, type-safe, composable, framework-agnostic, and built with TypeScript.

ts-rust, also distributed as tsc-rs, is an experimental Rust port of Microsoft's native TypeScript 7 compiler. It includes the compiler, type checker, language server, and API, following the upstream Go compiler's command-line behavior and algorithms. It can be installed from npm with `tsc-rs` and used with `npx tsc-rs -p tsconfig.json`; standalone binaries are provided for Linux x64 and macOS arm64, while Windows and Linux arm64 are not yet available. The port also includes Effect language-service diagnostics when enabled through the corresponding TypeScript plugin configuration. The project is an early release with documented compatibility issues involving some monorepos, project-build output, and long editor sessions, and is licensed under MIT.
