🌱 Choysum: TypeScript runtime for customization and extension, with out-of-the-box ERP core modules.
- ⚡ Full-Stack TypeScript Development: Unified TypeScript for both frontend and backend development. With just TS/Vue, developers can complete the full-stack workflow from business modeling to page rendering, drastically lowering the learning curve and collaboration costs for teams.
- 🧩 Zero-Conflict Customization: Driven by the compile-time iterative model mechanism, it allows free overriding and extension of native features, achieving perfect isolation between core code and custom business logic.
- 🚀 Blazing-Fast Pure Go Core: Zero binary dependencies, single-file deployment, and out-of-the-box ready. The business layer operates completely free of Node.js dependencies, driven directly by a built-in high-performance engine to leverage Go's concurrent scheduling and extreme performance.
All business modules (including backend data models, service interfaces, and frontend Vue views) are written in strongly-typed TypeScript. Developers only need to master TS/Vue to build full-stack applications from business modeling to page rendering. End-to-end type safety not only drastically reduces the learning curve for teams, but also catches most common type errors at compile time.
Designed for complex customization needs, Choysum draws inspiration from iterative modular extension principles (inspired by Odoo). To eliminate performance overhead caused by "runtime magic" in dynamic languages, we have moved all model and page merging and replacement operations to compile time. This not only achieves a clean modular design that keeps core code pristine, but also delivers zero runtime overhead, significantly improving system maintainability and seamless upgrade efficiency.
The network layer is built on the gRPC-Native philosophy. Backend TypeScript domain services are automatically mapped to standard gRPC interfaces, and the frontend communicates with the backend via the framework's built-in grpc-web protocol. This eliminates boilerplate code for manual routing and serialization. Additionally, the system automatically generates standardized .proto contracts, allowing you to easily create cross-language SDKs and seamlessly integrate with existing microservice architectures.
The core engine is built in Go, with an embedded TypeScript compilation and execution engine. Business-layer TypeScript code runs entirely without external Node.js dependencies, executing efficiently in isolated runtime instances created by Go. This leverages Go's excellent concurrent scheduling to ensure system stability, while deployment only requires a single compiled Go executable, completely eliminating complex runtime environment dependencies.
The framework provides a high-level abstraction and unified dialect compatibility layer at the underlying ORM level. It natively supports the three major relational databases: PostgreSQL, MySQL, and SQLite (more databases are planned). This comprehensive low-level adaptation frees developers from worrying about database-specific syntax differences, allowing them to flexibly choose or migrate underlying storage based on business scale and deployment scenarios.
