I recently hit a major snag with a 1,200 line config/routes.cfm with Lucee 4.5 throwing a nasty "Method code too large" exception..

After the wave of panic had subsided.. the fix was relatively simple. By the grace of Odin, coldroute’s drawRoutes() function can be called multiple times and results in the same routes structure as if it were called a single time.

I split my monstrous routes file into smaller includes located in a new config/routes directory, then simply included them in the main config/routes.cfm

myapp/config/routes/admin.cfm

drawRoutes()
  .get(to="admin.Foo##index", name="fooIndex", pattern="admin/foo")
  .post(to="admin.Foo##update", name="fooUpdate", pattern="admin/foo/update/[key]")
  ...
.end();

myapp/config/routes/public.cfm

drawRoutes()
  .get(to="public.Pages##index", name="pagesIndex", pattern="/pages")
  .post(to="public.Pages##show", name="pagesShow", pattern="/pages/show/[key]")
  ...
.end();

myapp/config/routes/user.cfm

drawRoutes()
  .get(to="users.Bar##index", name="barIndex", pattern="/bars")
  .get(to="users.Bar##new", name="barNew", pattern="/bars/new")
  ...
.end();

And simply include in the main routes  like so:

myapp/config/routes.cfm

include "routes/admin.cfm";
include "routes/public.cfm";
include "routes/user.cfm";
// default routes
drawRoutes()
 .wildcard()
 .root(to="public.site##home")
.end();

I hope this saves you that wave of panic..
