Introduction

Or...Why This Project Exists

Portability

In the modern software development landscape, the ability to deploy applications across various environments and platforms is crucial. Developers often face challenges when trying to ensure that their applications run seamlessly on different runtimes such as Node.js, Deno, Bun, Cloudflare Workers, AWS Lambda and more. Each of these runtimes has its own set of features, performance characteristics, and limitations, making it difficult to write code that is truly portable.

Standardization

Decorators and reflect metadata are not yet part of the official ECMAScript standard, leading to inconsistencies in their implementation across different runtimes. This lack of standardization can result in compatibility issues and hinder the adoption of these features in production environments. This project aims to provide a consistent and reliable way to use decorators across multiple JavaScript runtimes, ensuring that developers can leverage these powerful features without worrying about compatibility issues.

We embraced the latest (stage 3) TC39 proposals for decorators, following Deno's lead in adopting these features.

Field Experience

Working alongside engineers using Angular and NestJS frameworks, we observed a common desire for a more streamlined and efficient way to build server-side applications. Teams love the class based API approach and the decorator syntax, but often find themselves constrained by the limitations of their chosen runtime or framework.

The expansion of serverless computing and the rise of edge computing have further highlighted the need for a unified approach

Philosophy

It can be simpler. It can be better. Why not?
