express-except

Skip middleware when a path matches

This package works with Express v5. For Express v4 support, use express-except@1.

Install

npm install express-except

Usage

require('express-except')

app.useExcept('/skip', (req, res) => res.send('stopped'))

app.use((req, res) => res.send('skipped'))

// GET /skip => skipped
// GET /other => stopped

Explanation

When you require this package, the following Express middleware mounting methods are added:

• app.useExcept (opposite of app.use)
• app.allExcept (opposite of app.all)
• app[METHOD + 'Except'] (opposite of app[METHOD])
• router.useExcept (opposite of router.use)
• router.allExcept (opposite of router.all)
• router[METHOD + 'Except'] (opposite of router[METHOD])

You can then use one of those methods to mount middleware that WILL NOT run if the path matches. Each new method has the same signature as its corresponding Express method. This library uses only built-in Express functionality and does not attempt to match routes manually.
