[INFO REQ] Using Scheduling Engine in backend (node)

[misto]

Hi,
I want to calculate start date of tasks using scheduling engine, but is not working.

Result: null, 2000-01-01, 2000-01-01
Excepted: 2000-01-01, 2000-01-01, 2000-01-10

NB: I can't use SchedulerProProjectMixin because it is using window.

// import { SchedulerProProjectMixin } from './lib/Engine/quark/model/scheduler_pro/SchedulerProProjectMixin.js';
// const project = new SchedulerProProjectMixin();
import { SchedulerCoreProjectMixin } from './lib/Engine/quark/model/scheduler_core/SchedulerCoreProjectMixin.js';
const project = new SchedulerCoreProjectMixin();
project.loadInlineData({
    eventsData: [
        {
            name: 'All Tasks',
            id: 'all',
            children: [
                { id: 't1', name: 'Task 1', startDate: '2000-01-01', endDate: '2000-01-10' },
                { id: 't2', name: 'Task 2', startDate: '2000-01-01', endDate: '2000-01-10' }],
        }
    ],
    dependenciesData: [
        {
            id: 't1', fromEvent: 't1', toEvent: 't2',
        }
    ],
}).then((res) => {
    project.eventStore.forEach(element => {
        console.log(element.startDate);
    });
}).catch((err) => {
});

If I'm using SchedulerProProjectMixin (uncomment window.DEBUG) everything works fine.

Hi, misto!

I've checked a bit modified code with latest Nightly Build we have in Customer Zone (schedulerpro-2020-07-02-next).
All works fine with Node JS 14.5.

App code.

import { SchedulerProProjectMixin } from './lib/Engine/quark/model/scheduler_pro/SchedulerProProjectMixin.js';
const project = new SchedulerProProjectMixin();
project.loadInlineData({
    eventsData: [
        {
            name: 'All Tasks',
            id: 'all',
            children: [
                { id: 't1', name: 'Task 1', startDate: '2020-01-01', endDate: '2020-01-5' },
				{ id: 't2', name: 'Task 2', duration: '11' }
			]
        }
    ],
    dependenciesData: [
        {
            id: 'd1', fromEvent: 't1', toEvent: 't2',
        }
    ],
}).then((res) => {
	project.eventStore.forEach(element => {
        console.log(`${element.name} : ${element.startDate} - ${element.endDate}`);
    });
});

Please download and check with the latest Nightly sources.

Thanks, it's ok for me, I compiled sources (ts) with "module": "commonjs"and some ts-ignore, so I can use in node 12.

Hey Misto,

Would you mind sharing your project config? I'm planning to do something similar using GanttProjectMixin. I tried both JS and TS with different setups but ran into problems each time (module issues, TS compilation issues, lint problems etc.).

It's great that you were able to get it working using node 12.

Your help would be greatly appreciated.

Cheers,
Istvan

Hi Mihai,

WOW, this is much more complex than I thought. You spared an awesome lot of time of trial and error for me.

Thanks!
