Traces all dispatched Hyperapp actions and effects.

• Logs the state and properties arguments with which every action is dispatched.
• Parses and logs the return value of every action.
• Logs the properties argument with which every effect is dispatched.

For example:

npm install hyperapp-debug-trace

Import traceDispatch and pass it to Hyperapp as middleware.

import { app } from 'hyperapp';
import { traceDispatch } from 'hyperapp-debug-trace';

app({
  init: initialState,
  view: appView,
  subscriptions: subscriptionsFn,
  middleware: traceDispatch,
  node: appElement,
});

• Define your actions and effects as named functions (i.e. not anonymous). This will make the trace output much more informative.
• When minifying an app with tracing enabled, preserve the function names of your Actions and Effects. (For example, this can be done with Terser using the keep_fnames setting.)
