App hooks

Set hooks on the server to run them across requests.

var server = require('@nodedk/server')

server({
  routes: [{ paths: '/', handler: () => 'Hello!' }],
  begin: function (state) {
    state.data.started = Date.now()
  },
  before: function (state) {
    state.res.setHeader('x-app', 'example')
  },
  after: function (state) {
    if (!state.res.headersSent) {
      state.res.setHeader('x-request-id', state.req.id)
    }
  }
})

begin runs before routing and body parsing. before runs for matched routes. after runs before the normal response is sent. Static files may have already sent headers.
