async-await-error-handler

async-await-error-handler is a lightweight JavaScript library designed to simplify error handling in asynchronous operations, particularly with promises and async/await syntax in Node.js applications. It offers a more elegant alternative to traditional try-catch blocks, making your code cleaner and easier to maintain.

Features

• Custom Error Classes: Differentiate between operational and programmer errors for more nuanced handling.
• Customizable Error Handling: Inject custom logic to handle errors precisely as needed.
• Error Logging: Integrated error logging capabilities, with support for custom logging strategies.
• Flexible Response Formatting: Customize how error responses are formatted and returned to clients.

Installation

Install the package with npm:

npm install async-await-error-handler

Or with yarn:

yarn add async-await-error-handler

Usage

Basic Usage

Wrap your async route handlers to automatically catch and handle errors.

const express = require('express');
const { catchErrors } = require('async-await-error-handler');

const app = express();

app.get('/example', catchErrors(async (req, res) => {
// your async code here
}));

app.use((err, req, res, next) => {
  res.status(500).send('Something broke!');
});

Advanced Usage

Utilize custom error classes and enhanced error handling features for more complex scenarios.

const { asyncHandler, OperationalError, errorHandlerWithLogging } = require('async-await-error-handler');

app.get('/example', asyncHandler(async (req, res) => {
  if (!req.query.id) {
    throw new OperationalError("Missing 'id' query parameter");
  }
// async operation
}, errorHandlerWithLogging));
