Express Conditional Middleware
This module provides a conditional middleware for express. Use as follows:
var conditional = require('express-conditional-middleware');
// Simple boolean method.
app.use(conditional(true, function (req, res, next) {
// ...
});
// Function method.
app.use(conditional(
function (req, res, next) {
return req.get('accept') === 'application/json';
},
function (req, res, next) {
// ...
}
));
// Failure middleware.
app.use(conditional(
function (req, res, next) {
return req.get('accept') === 'application/json';
},
function (req, res, next) {
// Executed if 'accept' === 'application/json'
},
function (req, res, next) {
// Executed if 'accept' !== 'application/json'
}
));
