Install

npm i -D alt-logger

Usage

import Alt from 'alt';
import createLogger from 'alt-logger';
 
export default createLogger(new Alt());

At the moment it's not possibly to add a custom dispatcher to alt, because it would override the DebugDispatcher.

Options

{
  collapsed: true, // Defines if the log group should be collapsed or not
  colors: {
    title: '#2ecc71',
    prevState: '#3498db',
    action: '#2ecc71',
    nextState: '#3498db'
  }, // Object with the log colors.
  timestamp: true, // Print the timestamp with the action name
  duration: true, // Print the duration
  transformState: state => state, // Transform state before print.
  transformAction action => ({
    'payload': action.payload,
    'type': action.type,
    'id': action.id
  }), // Transform action before print.
  predicate: undefined // If specified this function will be called before each action is processed with this middleware. If false is returned the log process is interrupted.
}

Tips

Log only in development

import Alt from 'alt';
import createLogger from 'alt-logger';
 
const alt = new Alt();
export default (process.env.NODE_ENV === 'development') ? createLogger(alt) : alt;

Collapse everything except actions with a certain type

    createLogger(alt, {
        collapsed: (action) => action.type !== USER_ACTION
    });

Only log actions with a certain type

    createLogger(alt, {
        predicate: (action) => action.type === USER_ACTION
    });
