Express Reverse Routing Helper

NPM version

Install

npm install express-reverse

Example

var app = require('express')();
require('express-reverse')(app);

app.get('test', '/hello/:x', function(req, res, next) {
  res.end('hello ' + req.params.x);
});

app.get('/test-redirect', function(req, res, next) {
  res.redirectToRoute('test', { x: 'world' });
});

Jade:

a(href=url('test', { x: 'world' })) Test

EJS:

<a href="<%= url('test', { x: 'world' }) %>">Test</a>

Methods

module(app, [options])

  • app Express app
  • options (optional) Defaults: { helperName: 'url' }

Augments the default Express routing methods app.VERB(path, [callback...], callback) to accept an optional routeName parameter app.VERB([routeName], path, [callback...], callback).

Helpers

url(routeName, [parameters])

  • routeName The route name specified when defining a route with app.VERB(...).
  • parameters (optional) An object defining the URL replacement values. For example { x: 123 } will replace :x with 123 in the route '/test/:x'. Also note that replacement values are required for all URL parameters except for optional ones (i.e. '/test/:x?').

Adds a new application helper function in app.locals (named 'url' by default) with the signature url(routeName, replacements)

Middleware

res.redirectToRoute([status], routeName, [parameters])

  • status (optional) Optional status code number (e.g. 301).
  • routeName See helper description.
  • parameters (optional) See helper description.
