URL rewrite middleware for koa.
Notice: koa-rewrite@2+
supports koa@2
, if you want to use this module with koa@1
, please use koa-rewrite@1
.
$ npm install koa-rewrite
Rewrite using a regular expression, rewriting
/i123
to /items/123
.
app.use(rewrite(/^\/i(\w+)/, '/items/$1'));
Rewrite using route parameters, references may be named
or numeric. For example rewrite /foo..bar
to /commits/foo/to/bar
:
app.use(rewrite('/:src..:dst', '/commits/$1/to/$2'));
app.use(rewrite('/:src..:dst', '/commits/:src/to/:dst'));
You may also use the wildcard *
to soak up several segments,
for example /js/vendor/jquery.js
would become /public/assets/js/vendor/jquery.js
:
app.use(rewrite('/js/(.*)', '/public/assets/js/$1'));
Use the DEBUG environment variable with "koa-rewrite":
