slay-error

Standard, sane defaults for HTTP errors in slay apps.

Usage

You should use this within your middlewares.js in your Slay app

middlewares.js
`` js
module.exports = function (app, opts, done) {
//
// All your other middlewares first (most of the time)
//

//
// Generally you want your error handling last.
//
app.use(require('slay-error')(app, { disableLog: false }));
};
`
In your application, when you pass an error to the next(error)
callback of a request handler, this middleware will handle the reporting
and response for that error in your application.
`
module.exports = function handler(req, res, next) {
// if error
next(new Error('let the middleware handle this'));
};
`

If the error that you pass to this middleware has a location property,
res.location(error.location) will be called for you.

If you don't want the error logged, you can use the option disableLog:
true or set the log property of the error to false.

You can also control the log level of the error using the level
property. So, if level: 'info' only app.log.info will be invoked
with the log message and metadata.

In your application you can use a tool like errs that
will allow you to define the structure of errors, either with
pre-defined/registered errors or by passing all of the properties of the
error to errs.create`
