npm install havana-error
An error response handler.
Havana error works with a request/response dispatcher such as
Havana server,
Havana browser
or a library with an interchangeable API. When a dispatcher
publishes a response.error event, Havana error will in turn
publish a response.send event with a 404 response.
``
npm install havana-error
`javascript
import Error from 'havana-error';
import Event from 'havana-event';
import Server from 'havana-server';
const event = new Event();
const reporting = {
'level': 2,
'reporter': console.log,
};
const server = new Server({
'event': event,
'reporting': reporting,
});
new Error({
'event': event,
'reporting': reporting,
});
server.listen( 3000 );
`
Events take the form of
Havana event
or a library with an interchangeable API.
- response.send: Signifies that Havana error has handled
a response error, publishing the response data for
consumption by a request/response dispatcher.
- response.error: Allows a request/response dispatcher
to notify Havana error that all registered handlers have
failed to handled a request.
Havana error is written using ES2015+ syntax.
However, by default this module will use an ES5
compatible file that has been compiled using
Babel.
In the dist directory there are four files, the defaulterror.server.js
is . The default when using a client-sideerror.browser.js
bundler that supports the
browser field
spec is .
Havana error currently requires the
Babel polyfill.
You are expected to supply this yourself. However, as a
courtesy you will also find error.server.with-polyfill.js
and in the dist`
directory.
