🐛 MondJS
Monadic Error Handling for JavaScript/TypeScript
👋🏼 About
MondJS is a lightweight JavaScript/TypeScript library that brings monadic error handling, inspired by Rust, to your codebase.
This approach to error handling is more robust and reliable than traditional exception handling, which should be reserved for truly exceptional cases, rather than used as the primary method for managing common errors in general situations.
🚀 Getting Started
Installation 📥
You can install MondJS using your preferred package manager:
npm:
npm install mondjs
yarn:
yarn add mondjs
pnpm:
pnpm add mondjs
Basic examples 🔎
These basic examples show very briefly two of the characteristics of MondJS: Result
and Option
.
import { type Result, ok, err } from "mondjs";
function divide(a: number, b: number): Result<number, string> {
if (a === 0 || b === 0) {
return err("Divided by 0.");
}
return ok(a / b);
}
const result = divide(4, 0).unwrap();
console.log(result);
import { type Option, some, none } from "mondjs";
type User = {
id: number;
name: string;
};
const users: User[] = [
{ id: 1, name: "Alice" },
{ id: 2, name: "Bob" },
];
function findUserById(id: number): Option<User> {
const user = users.find((user) => user.id === id);
return user ? some(user) : none();
}
const defaultUser: User = { id: 3, name: "Jhon" };
const userOption = findUserById(3).unwrapOr(defaultUser);
console.log(userOption);
