Express-js wildcard routing to cover everything under and including a path

Question

I m trying to have one route cover everything under  foo including  foo itself  I ve tried using  foo  which work for everything except it doesn t match  foo  Observe   var express   require  express        app   express createServer     app get   foo    function req  res  next     res write  Foo  n      next         app get   foo   function req  res     res end  Foo n         app get   foo bar   function req  res     res end  Foo Bar n         app listen 3000     Outputs      curl localhost 3000 foo Foo   curl localhost 3000 foo bar Foo  Foo Bar   What are my options  The best I ve come up with is to route  fo  which of course isn t very optimal as it would match way too much

In array you also can use variables passing to req params   app get     foo      foo  bar       function

The connect router has now been removed  https   github com senchalabs connect issues 262   the author stating that you should use a framework on top of connect  like Express  for routing   Express currently treats app get   foo    as app get    foo        removing the need for two separate routes   This is in contrast to the previous answer  referring to the now removed connect router  which stated that    in a path is replaced with       Update  Express now uses the  path-to-regexp  module  since Express 4 0 0  which maintains the same behavior in the version currently referenced  It s unclear to me whether the latest version of that module keeps the behavior  but for now this answer stands

I think you will have to have 2 routes  If you look at line 331 of the connect router the   in a path is replaced with    so will match 1 or more characters   https   github com senchalabs connect blob master lib middleware router js  If you have 2 routes that perform the same action you can do the following to keep it DRY   var express   require  express        app   express createServer     function fooRoute req  res  next      res end  Foo Route n       app get   foo    fooRoute   app get   foo   fooRoute    app listen 3000

It is not necessary to have two routes  Simply add       at the end of your path string  For example  app get   hello world                   Here is a fully working example  feel free to copy and paste this into a  js file to run with node  and play with it in a browser  or curl   const app   require  express         will be able to match all of the following const test1    http   localhost 3000 hello world  const test2    http   localhost 3000 hello world   const test3    http   localhost 3000 hello world with more stuff      but fail at this one const failTest    http   localhost 3000 foo world   app get   hello world         req  res    gt  res send       This will match at example endpoints   lt br gt  lt br gt       lt pre gt  lt a href  quot   test1  quot  gt   test1  lt  a gt  lt  pre gt       lt pre gt  lt a href  quot   test2  quot  gt   test2  lt  a gt  lt  pre gt       lt pre gt  lt a href  quot   test3  quot  gt   test3  lt  a gt  lt  pre gt        lt br gt  lt br gt  Will NOT match at   lt pre gt  lt a href  quot   failTest  quot  gt   failTest  lt  a gt  lt  pre gt       app listen 3000       gt  console log  Check this out in a browser at http   localhost 3000 hello world
