fail-nicely
A one-liner to at least explain why things didn't work out
Example
See demo: fail-nicely
npm install fail-nicely
var createHandler = ; var handlerFailure = ; { console;} // Execute the callback with a failure:; // Execute the onSuccess callback:;
You can also just pass it an error:
try var y = 7 + g; catch e ;
The factory pattern is just a little convoluted, but the upshot is that intercepting fatal errors becomes a simple one-liner:
var fs = fs
Usage
require('fail-nicely')(callback[, options])
Returns a node-style callback (function (err, data)
) that intercepts and handlers errors and otherwise forwards data through to callback
.
When err
is truthy, appends an overlay to the body element with a short explanation of what happened. Usefulf for making quick and ugly demos a little less ugly. If the first argument is an Error
, it will use the error's message. If it's a string, that will be the explanation. Options are:
bg
: overlay background color (default:'#333'
)fg
: overlay foreground (text) color (default:'#fff'
)zIndex
: z-index of the overlay (default:9999
)title
: heading title (default:'Sorry!'
)fontFamily
: font family (default:Helvetica, Arial, sans-serif
)position
: positioning of the overlay element (default:fixed
)invert
: quick shorthand for swapping the foreground/background colors
Returns: Nothing.
