URL rewrite middleware for express
npm install express-urlrewriteURL rewrite middleware for express.
Rewrite using a regular expression, rewriting /i123 to /items/123.
``js`
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:
`js`
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,/js/vendor/jquery.js
for example would become/public/assets/js/vendor/jquery.js:
`js`
app.use(rewrite('/js/*', '/public/assets/js/$1'));
In the above examples, the original query string (if any) is left untouched.
The regular expression is applied to the full url, so the query string
can be modified as well:
`js`
app.use(rewrite('/file\\?param=:param', '/file/:param'))
The query string delimiter (?) must be escaped for the regular expression
to work.
`js`
app.use(rewrite('/path', '/anotherpath?param=some'))
now updates req.query, so req.query.param == 'some'.
rewrite can be used as a route middleware as in
`js
app.get('/route/:var', rewrite('/rewritten/:var'));
app.get('/rewritten/:var', someMw);
`
Instead of passing control to next middleware, it passes control to next route.
Set environment variable DEBUG=express-urlrewrite`
