Inheritance and the prototype chain

📖 Introduction

Inspired by the work of sindresorhus, I decided to open source the most repetitive encapsulation work I do in CLI development.

I do not like disorder. Often, unexpected situations arise due to our insufficient consideration. Therefore, I encourage those around me to engage in more comprehensive error collection work.

The goal of Exception is to transform unexpected occurrences into anticipated outcomes as much as possible.

It allows Error objects to throw exception and stack information in a more aesthetically pleasing and intuitive manner, and can also serve as Notify to output critical information in workflows.

⚙️ Installation

npm install @kabeep/exception --save

yarn add @kabeep/exception

pnpm add @kabeep/exception

Plain text or Error object
