Generate realistic user action logs.

Let's create action logs by specifying user characteristics and period. More advanced customization is possible by creating user action routines and action tables.

Usage

import FictionalLogGenerator from '../src/FictionalLogGenerator';
import moment from 'moment';

const flg = new FictionalLogGenerator();

function userAction(act, leave, nextActions, state) {
  nextActions.forEach(nextAction => {
    switch (nextAction.action) {
      case 'transit':
        state.prevView = state.view;

        if (nextAction.detail.view === '$back') {
          state.view = state.prevView;
        } else {
          state.view = nextAction.detail.view;
        }

        act({ ...nextAction, detail: { view: state.view } });
        if (state.view === 'Leave') {
          leave();
        }
        break;
      case 'select':
        state.selectedItem = BookItems.choiceFromRank(1, 5);
        act({ ...nextAction, detail: { item: state.selectedItem } });
        break;
      case 'search':
        const searchWordIndex = Math.floor(Math.random() * state.searchWordCandidates.length);
        state.searchWord = state.searchWordCandidates[searchWordIndex];
        state.selectedItem = BookItems.searchFromWord(state.searchWord);
        act({ ...nextAction, detail: { word: state.searchWord } });
        break;
      case 'addToCart':
        state.cart.push(state.selectedItem);
