express-redirect

express-redirect

express-redirect offers you simple and blazing fast redirection rules. Even very complex redirect rules don't take longer than 1 ms. It just comes down to concatenating strings.

Say goodbye to writing 10 lines of code for a plain redirection over and over again.

If you want redirections with fancy JS expressions, you should probably check out deviate.

Deprecation Notice

This package isn't actively maintained anymore. It was written for express v3.x, but still seems to work with express v4.x. Use it at your own risk.

If you want to continue this project, ping me and I'll add you as an owner on npm.

Installation

$ npm install express-redirect

var express = require("express")
  , redirect = require("express-redirect");

var app = express();
redirect(app); // mount the plugin

Example

// just a smple redirect
app.redirect("/p/:id", "/page/:id");

// you want it permanent?
app.redirect("/p/:id", "/page/:id", 301);

// if you want to append the query string (?foo=bar)
app.redirect("/p/:id", "/page/:id", 301, true);

// no id, goto page # 1
app.redirect("/p/:id?", "/page/:id(1)");

// only redirect POST (for whatever reason)
app.redirect("/contact", "/thanks", "post")

// a bit more complex
app.redirect(
  "/entry/:entry/comments/:action(view|edit|delete)?/:id([0-9]+)/:reply([0-9]+)?",
  "/entry/:entry/comments/:action(view)/:id/:reply?"
);

// external redirects work too
app.redirect(
  "/google/:query?",
  "https://www.google.de/?q=:query(Nyan+Cat)"
);

API

express-redirect mounts the new method app.redirect(route, target, [status], [method], [qsa]) to your app. You can access it just like app.get() or app.post() etc.

route

The parameter route is a string and is required. It can contain parameters like :id, :year([0-9]{4})? or :action(view|edit). It's basically just the same as a route you would pass to app.get().

target

The parameter target is a string and is required. It can contain parameters like :id, :year? or :action(view), where a ? marks an optional parameter and (someString) is a default value.
The parameters get replaced by their respective counterparts in the route.

app.redirect("/a/:id([0-9]+)?", "/b/:id(1)");
app.redirect("/c/:action(view|delete)?", "/d/:action?");

/a           -> /b/1
/a/100       -> /b/100
/c           -> /d
/c/view      -> /d/view

status

The parameter status is an integer and is optional. It is a HTTP (redirection) status code. It defaults to 307 (Temporary Redirect).

method

The parameter method is a string and is optional. It is a VERB as in express' router. It defaults to all.

qsa

The parameter qsa is a boolean and is optional. It defaults to false. If set to true, the query string will be appended. By default, it will be discarded.
