Create Express middleware which results in an HTTP 404 Not Found error.
Table of Contents
Requirements
This library requires the following to run:
- Node.js 18+
Usage
Install with npm:
npm install @rowanmanning/not-found
Load the library into your code with a require
call:
const notFound = require('@rowanmanning/not-found');
Create middleware which results in an HTTP 404 error in Express:
const express = require('express');
const notFound = require('@rowanmanning/not-found');
const app = express();
app.use(notFound());
Handle the 404 error like you would any other error in Express:
app.use((error, request, response, next) => {
response.status(error.status); // 404
response.send(error.message); // Not Found
});
Customise the error message with an option:
app.use(notFound({
message: 'This page does not exist'
}));
app.use((error, request, response, next) => {
response.status(error.status); // 404
response.send(error.message); // This page does not exist
});
