🔒 Safe Try Catch
Safe and structured error handling for JavaScript.
⚡ Features
- 🔄 Safe error handling for synchronous and asynchronous functions
- 🔍 Supports
try/catch
for both sync and async operations - 🎯 Clear separation between success and failure using
Result<T, E>
- 🛠 Compatible with Promises
- 📦 Easy integration with existing codebases
- 💡 Inspired by Rust’s error-handling model
📦 Install
# Using npm
npm install safe-try-catch
# Using yarn
yarn add safe-try-catch
# Using pnpm
pnpm add safe-try-catch
# Using bun
bun add safe-try-catch
📋 Usage
Basic Example
Wraps synchronous or asynchronous functions with safe error handling.
import { safeTry } from 'safe-try-catch';
const [result, error] = safeTry(() => {
throw new Error("This is an error");
});
Wrapping a function
Wraps a function to handle errors safely, and can be used with both synchronous and asynchronous functions.
import { wrapTry } from 'safe-try-catch';
// Unsafe synchronous function
function unsafeSyncAction(value: string): string {
if (value === "") throw new Error("Value is empty");
return value.trim();
}
const safeAction = wrapTry(unsafeSyncAction);
const [result, error] = safeAction(" Hello World ");
if (error) {
console.error(error.message);
} else {
console.log(result); // "Hello World"
}
📗 API
safeTry(fn: () => T): Result<T, Error>
- Description: Directly executes a function or block of code inside error handling. Ideal for quick, inline code execution.
- Parameters:
fn
: A synchronous function to be executed.
- Returns: A tuple
[result, error]
.
wrapTry<T, E>(fn: (...args: any[]) => T | Promise<T>): (...args: any[]) => Promise<Result<T, E>>
- Description: Wraps a given function (synchronous or asynchronous) in safe error handling. Returns a function that handles errors and returns a Promise.
- Parameters:
fn
: A function to be wrapped that returns a value or a Promise.
- Returns: A function that returns a Promise containing a tuple
[result, error]
.
