express-catchify

A simple async wrapper for Express routes to handle errors cleanly.
Avoid repetitive try-catch blocks in your async route handlers.

Features

• Wraps async Express route handlers
• Automatically passes errors to Express error middleware
• Lightweight and dependency-free (except Express)

Installation

Using npm:

npm install --save express-catchify

Using yarn:

yarn add express-catchify

Usage

With express-catchify

import express from 'express';
import catchify from 'express-catchify';

const app = express();

app.get('/', catchify(async (req, res) => {
    const data = await fetchData(); // async operation
    res.send(data);
}));

// Global error handler
app.use((err, req, res, next) => {
    res.status(500).json({ message: err.message });
});

app.listen(3000, () => console.log('Server running on port 3000'));

Without express-catchify

import express from 'express';

const app = express();

app.get('/', (req, res, next) => {
    fetchData()
        .then(data => res.send(data))
        .catch(next); // error passed to global error handler
});

app.use((err, req, res, next) => {
    res.status(500).json({ message: err.message });
});

app.listen(3000, () => console.log('Server running on port 3000'));
