Show HN: Skir – like Protocol Buffer but better

3 days ago

Skir is a declarative language for defining data types, constants, and APIs.
Write schema in .skir files and generate type-safe code in multiple languages (TypeScript, Python, Java, C++).
Simple workflow: one YAML file and one command with watch mode for automatic recompilation.
Generated code is idiomatic and native to each language.
Example schema includes structs like `Point` and `Shape` with fields and documentation.
Supports constants (e.g., `TOP_RIGHT_CORNER`) and immutable object creation.
Serialization to dense JSON for compact storage and schema evolution.
Built-in guidelines for safe schema evolution in distributed systems.
Define API methods in Skir (similar to gRPC) to ensure client-server sync.
Example API method `WhatToWear` with request/response structs.
Supports remote invocation with generated client code.
Full-stack applications can use Skir for data exchange between backend (e.g., Kotlin) and frontend (TypeScript).
Multiple serialization options: dense JSON, readable JSON, or binary.
Import types directly from GitHub repositories to share common data structures.
VS Code extension with real-time validation, code completion, and formatting.
Quick setup with a single YAML file for project configuration.
