Prerequisites

This project requires node and npm. Go check them out if you don't have them locally installed.

Install

Use simple Middleware to manage exceptions for Express @joellesenne/express-async-handler

pnpm install --D @joellesenne/express-async-handler @joellesenne/express-validation-error

# OR
npm install --save-dev @joellesenne/express-async-handler @joellesenne/express-validation-error

# OR
yarn add -D @joellesenne/express-async-handler @joellesenne/express-validation-error

Usage

This code is an Express.js HTTP GET route which is using an asyncHandler. It attempts to find 'foo' using the findAll() function, and if it doesn't exist, it throws a ValidationError which can be handled by the next function. If it successfully finds 'foo', the response will send the data (bar) back to the client.

const asyncHandler = require('@joellesenne/express-async-handler')
const ValidationError = require('@joellesenne/express-validation-error')

express.get('/', asyncHandler(async (req, res, next) => {
  try {
    const bar = await foo.findAll();
    if (!bar) {
      return next(new ValidationError("No bar valid", 404));
    }
    res.send(bar)
  } catch (error) {
    return next(error);
  }
}))
