Improves express compatibility

Improves support for express based middlewares by populating req.originalUrl

req.originalUrl === req.url // -> TRUE

More details: #45

Calling next(err)within middlewares will now also trigger the global errorHandler if present.

Expose internal HTTP Server instance

Merge pull request #42 from jkyberneees/expose-http-server

Expose internal http server

Making errorHandler optional for typescript

Fixes restana config options definitions:

• Make errorHandler an optional property.

Properly handler error codes

Prevent invalid status codes from being send in case of errors.

Drop turbo-http support.

Support for turbo-http was dropped in v3.x.
As it shows very low level and not fully compatible with Node.js native HTTP interfaces, limiting the evolution of the features we can support.

Improving error handling

Supporting global error handler overwrite:

const service = require('restana')({
  errorHandler (err, req, res) {
    console.log(`Unexpected error: ${err.message}`)
    res.send(err)
  }
})

service.get('/throw', (req, res) => {
  throw new Error('Upps!')
})

service.start()

TS definitions !!!

Thanks to @tomc974 collaboration, restana now have proper typescript definitions!!!

service.getConfigOptions()

Details: #30

Support method chaining on routes registration

    .get('/', ...)
    .post('/', ...)
    .get('/chain', ...)
