URL Rules
In addition to the page server features, Los Angeles includes a simple URL rewrite, redirect and proxy feature.
Setup
To setup the URL mapping use the urlRules()
method of the Los Angeles component which
returns an Express middleware:
// Load LosAngeles
const la = require('@toptensoftware/losangeles');
// Run redirect rules
app.use(la.urlRules([
// redirect rules go here (see below)
]));
Configuring Rules
The urlRules()
method expects an array of rules that should be processed.
Each entry in the array is a JavaScript object with either a redirect
, rewrite
or proxy
field declaring a regular expression to match against the URL and a to
property specifying where the URL should be remapped:
[
// Redirect
{
redirect: /^\/downloads\/(.*)$/i,
to: "http://static.mysite.com/$1"
},
// Rewrite
{
rewrite: /^\/downloads\/(.*)$/i,
to: "/newblog/$1"
},
// proxy
{
proxy: /^\/myproduct\/releasenotes.json/i,
to: "http://static.mysite.com/myproduct-releaseNotes.json"
}
