A clone of better_errors for Clack.
By default, when Clack throws an exception when rendering a page, the server waits for the response until it times out while the exception waits in the REPL. This isn't very useful. So now there's this.
This,
(clack:clackup
(funcall clack-errors:*clack-error-middleware*
*my-clack-app*
:debug t)
:port 8000)))
will wrap your Clack up in the clack-errors middleware, start the server and return a handler object.
By default, the middleware will show all information. In a production
environment, you'll want to initialize this with the :debug parameter set to
NIL.
The middleware can be initialized with the :fn slot set to a lambda that takes
a condition as its argument and returns the HTML string to return to the client.
(clack:clackup
(funcall clack-errors:*clack-error-middleware*
*app*
:fn (lambda (condition) "500 Internal Server Error")))

A clone of [better_errors](https://github.com/charliesome/better_errors)
for [Clack](https://github.com/fukamachi/clack).
By default, when Clack throws an exception when rendering a page, the server
waits for the response until it times out while the exception waits in the
REPL. This isn’t very useful. So now there’s this.
# Usage
This,
“‘lisp
(clack:clackup
(funcall clack-errors:*clack-error-middleware*
*my-clack-app*
:debug t)
:port 8000)))
“‘
will wrap your Clack up in the clack-errors middleware, start the server and
return a handler object.
By default, the middleware will show all information. In a production
environment, you’ll want to initialize this with the ‘:debug‘ parameter set to
NIL.
## Using a Custom Error Page
The middleware can be initialized with the ‘:fn‘ slot set to a lambda that takes
a condition as its argument and returns the HTML string to return to the client.
“‘lisp
(clack:clackup
(funcall clack-errors:*clack-error-middleware*
*app*
:fn (lambda (condition) "500 Internal Server Error")))
“‘
