Logger

Wobe has a logger beforeAndAfterHandler that allows to log something before and after a function is called. For example, it can be useful to log the time taken by an handler to execute.

Example

By default the logger middleware will use console.logto log the message.

import { Wobe, logger } from 'wobe'

const app = new Wobe()

app.beforeAndAfterHandler(logger())
app.get('/test', (req, res) => {
	res.send('Hello World')
})
app.listen(3000)

You can also pass a custom function (see Options sections) to the logger middleware.

import { Wobe, logger } from 'wobe'

const app = new Wobe()

app.beforeAndAfterHandler(
	logger({loggerFunction : ({	beforeHandler, method, url, status, requestStartTimeInMs}) => {
	   // Some log logic ...
	})
)
app.get('/test', (req, res) => {
  res.send('Hello World')
})
app.listen(3000)

Options

• loggerFunction (function) : the function that will be called to log the message.

Parameters of the function :

• beforeHandler (boolean) : true if the function is called before the handler, false otherwise.
• method (string) : the HTTP method of the request.
• url (string) : the URL of the request.
• status (number optional) : the status code of the response (only in afterHandler).
• requestStartTimeInMs (number optional) : the time in milliseconds when the request was received (only in afterHandler).
