Dancer::Plugin::Res - Syntax sugar for setting the status and returning a response
version 0.0003
use Dancer; use Dancer::Plugin::Res; post '/widgets' => sub { return res 400 => to_json { err => 'name is required' } unless param 'name'; # ... return res 201 => to_json { widget => $widget }; }; dance;
This Dancer plugin provides the keyword res(), which stands for response. It allows you to set the response and return a body in one shot.
res()
return res 400, { msg => reason };
is equivalent to:
status 400; return { msg => reason };
I made this plugin because I wanted a function like send_error() that behaved more consistently. send_error("reason ...", 500) will not always render the first argument you give it in the response. When your app is running in production mode with show_errors set to false, it will attempt to render a generic 500.html page. This is great for front-end only applications, but not for creating an api where you always want your application to render the thing that you told it to render.
send_error("reason ...", 500)
show_errors
res($status, [$reason])
Sets the status to $status and returns $reason. If $reason is not provided, returns an empty string.
