gantt-schedule-timeline-calendar
Advanced tools
Gantt, Schedule, Timeline, Calendar components all in one!
You can use it in react, vue, angular, svelte or any other projects.
You can use it as schedule for reservation system. You can use it for organizing events. You can use it as gantt chart. Or you can use it as calendar for different purposes.
gantt-schedule-timeline-calendar is very extensible and elastic. You can make your own plugins or modify configuration in couple of ways to achieve your goals. You can control almost everything. You can change html structure, stylize every html element and even override original components without any compilation stage!
npm i gantt-schedule-timeline-calendar
or
<script src="https://cdn.jsdelivr.net/npm/gantt-schedule-timeline-calendar"></script>
Basically you need to create some configuration described below, create state for it and mount component to DOM.
const config = {
/* ... */
};
const state = GSTC.api.stateFromConfig(config);
const app = GSTC({
element: document.getElementById('your-element-id'),
state
});
gantt-schedule-timeline-calendar is using deep-state-observer so you can checkout its documentation.
Your configuration will be merged recursively with default configuration options (default-config) so almost all options are optional.
TIP: most of the time when you need to modify html or add some events you will need to use actions
TIP: take a look at types or default-config

Rows can contain multiple items.
Rows configuration is an object where key is a row id ({string}) and value is an object with data you need for columns configuration or for your use case.
Row should have an id inside as id property {string}.
Rows can contain also those values:
parentId {string} - this is a parent row id for hierarchical data structuresexpanded {boolean} - if this row have children should it be expanded or collapsed?// example rows configuration (minimal)
const config = {
list: {
rows: {
'1': {
id: '1'
},
'2': {
id: '2',
parentId: '1'
},
'3': {
id: '3',
parentId: '2',
expanded: true
},
'4': {
id: '4',
parentId: '3'
}
}
}
};
data {object} - columns data configurationresizer {object} - resizer configurationpercent {number} - percentage width of all columns (0 - 100) if 0 list will disappear (from DOM)minWidth {number} - default minimal width of the column in pixelsColumns data configuration is an object where key is an id of the column ({string}) and value is column configuration.
Column configuration must contain id property too.
id {string} - id of the columndata {string | function} - for string it is a property name that should exists inside row configuration and will display coresponding value, if data is a function it will be executed with row as argument - that function should return a string or lit-html templateisHTML {boolean} - if set to true data option will be rendered as HTML so be careful and do not let user to inject anything unsafe!width {number} - width of the column in pixelsheader {object} - column header configurationexpander {boolean} - should this column contain expander?// example rows and columns configuration (minimal)

Basically locale configuration comes from dayjs locale object
name {string} - locale name (en for example)weekdays {string[]} - array of strings with weekdays starting from sunday (Sunday, Monday etc)weekdaysShort {string[]} - same as weekdays but little bit shorter (Sun, Mon ...)weekdaysMin {string[]} - shortest weekdays (Su, Mo ...)months {string[]} - month names as array of stringsmonthsShort {string[]} - shorter month namesweekStart {number} - week start number from 0 to 6 where 0 = sunday, 1 = mondayActions are functions (or classes) that can operate directly on DOM Tree.
With actions you can add additional event listeners, add/update/inject some HTMLElements or add behavior from third party libraries like popups or dialogs.
Action structure is an object where key is component name (kebab-cased) and value is an array of actions that should be fired. One action is executed on all elements/component instances of specified type.
Available action names:
mainlistlist-columnlist-column-headerlist-column-header-resizerlist-column-header-resizer-dotslist-column-rowlist-column-row-expanderlist-column-row-expander-togglelist-togglechartchart-calendarchart-calendar-datechart-timelinechart-timeline-gridchart-timeline-grid-rowchart-timeline-grid-row-blockchart-timeline-itemschart-timeline-items-rowchart-timeline-items-row-itemAction is a function that is fired when specified DOM Node is created and should return an object with update and destroy functions.
Each of the functions takes two arguments:
{HTMLElement}{object}update lifecycle method is fired when element stays where it was, but is reused to display another portion of data (performance optimization).
destroy is fired when element is removed from the DOM tree and component is destroyed.
Example action that will add title property to each item inside chart.
function addItemTitle(element, data) {
// fired when element / component is created for the first time
// you can console.log(data) to find out what is inside specified component data
element.title = data.item.label;
return {
update(element, data) {
// fired when element takes data from another item - data has been changed
element.title = data.item.label;
},
destroy(element, data) {
// fired when component is destroyed and element is to be removed from DOM tree
// you can clean up something here
element.title = '';
}
};
}
const config = {
actions: {
'chart-timeline-items-row-item': [addItemTitle]
}
};
Add item click event example:
function clickAction(element, data) {
function onClick(event) {
// data variable will be updated in update method below so it will be always actual
alert(`Event ${data.item.id} clicked!`);
}
element.addEventListener('click', onClick);
return {
update(element, newData) {
data = newData; // data from parent scope updated
},
destroy(element, data) {
element.removeEventListener('click', onClick);
}
};
}
const config = {
/* ... */
actions: {
'chart-timeline-items-row-item': [clickAction]
}
/* ... */
};
Actions can be classes too - with constructor, update and destroy methods.
class ItemClickAction {
constructor(element, data) {
this.data = data;
this.onClick = this.onClick.bind(this);
element.addEventListener('click', this.onClick);
}
update(element, data) {
this.data = data;
}
destroy(element, data) {
element.removeEventListener('click', this.onClick);
}
onClick(event) {
alert(`Item ${this.data.item.id} clicked!`);
}
}
const config = {
/* ... */
actions: {
'chart-timeline-items-row-item': [ItemClickAction]
}
/* ... */
};
Action example - add class if item has property example set to true.
class AddExampleClass{
constructor(element, data) {
this.data = data;
this.element = element;
this.updateExamplelass();
}
update(element, data) {
this.data = data;
this.element = element;
this.updateExampleClass();
}
destroy(element, data) {
element.classList.remove('example-class');
}
updateExampleClass() {
const hasClass = this.element.classList.contains('example-class');
if(this.data.example && !hasClass){
this.element.classList.add('example-class');
}else if(!this.data.example && hasClass){
this.element.classList.remove('example-class');
}
}
}
const config = {
/* ... */
chart:{
items:{
'1': {
id: '1',
time: {/* ... */},
label: 'with class',
example: true,
},
'2': {
id: '2',
time: {/* ... */},
label: 'without class',
example: false,
}
}
}
/* ... */
actions: {
'chart-timeline-items-row-item': [AddExampleClass]
}
/* ... */
};
gantt-schedule-timeline-calendar is using lit-html from polymer project to easly render templates without compilation stage, so if you want to wrap some GSTC component to add some functionality, you can use html from lit-html and wrappers and at the end your code will be much cleaner.
Wrappers are functions that takes TemplateResult from html (from lit-html) and returns wrapped (or not) version.
Wrappers configuration options is an object where key is component name and value is just function so you can use decorator pattern (replace that function) on it.
Available component names:
MainListListColumnListColumnHeaderListColumnHeaderResizerListColumnRowListColumnRowExpanderListColumnRowExpanderToggleListToggleChartChartCalendarChartCalendarDateChartTimelineChartTimelineGridChartTimelineGridRowChartTimelineGridRowBlockChartTimelineItemsChartTimelineItemsRowChartTimelineItemsRowItemExample that shows how to wrap list column row with div and additional class.
let oldWrapper;
function addClassWrapper(input, data) {
let result = oldWrapper(input, data);
result = html`
<div class="additional-class">${result}</div>
`;
return result;
}
// after GSTC is loaded and running so we could save oldWrapper
state.update('config.wrappers', wrappers => {
oldWrapper = wrappers.ListColumnRow;
wrappers.ListColumnRow = addClassWrapper;
return wrappers;
});
In gantt-schedule-timeline-calendar you can replace any component with your implementation.
Just copy interesting component - modify it and set up in components configuration property.
Component configuration is (just like above) object where key is a component name and value is just component itself.
Available component names:
MainListListColumnListColumnHeaderListColumnHeaderResizerListColumnRowListColumnRowExpanderListColumnRowExpanderToggleListToggleChartChartCalendarChartCalendarDateChartTimelineChartTimelineGridChartTimelineGridRowChartTimelineGridRowBlockChartTimelineItemsChartTimelineItemsRowChartTimelineItemsRowItemComponents are functions that takes operational functions vido and props as second argument.
Component must return a render function with html (lit-html).
function ExampleComponent(vido, props) {
const { html, update } = vido;
let name = 'John';
const onClickHandler = event => {
name = 'Jack';
update();
};
return () =>
html`
<div class="example-component" @click=${onClickHanlder}>Hello ${name}</div>
`;
}
By default there are couple of plugins available:
With this plugin you will be able shift / scroll view horizontally by grabbing and moving dates at the top.
speed {number} default: 1hideScroll {boolean} default: false - hide gstc bottom scrollbaronChange {function} - on change callback onChange(time){/*...*/}<script src="https://cdn.jsdelivr.net/npm/gantt-schedule-timeline-calendar/dist/CalendarScroll.plugin.js"></script>
or from your local node_modules dir
<script src="/node_modules/gantt-schedule-timeline-calendar/dist/CalendarScroll.plugin.js"></script>
or
import CalendarScroll from "gantt-schedule-timeline-calendar/dist/CalendarScroll.plugin.js"
const config = {
/*...*/
plugins: [
CalendarScroll({
speed: 1,
hideScroll: true,
onChange(time) {
console.log(time);
}
})
]
/*...*/
};
With this plugin you will be able to move / resize items.
moveable {boolean | string} - you can turn off moving capabilities and use just resizing feature, items also might be moveable only along with the specified axis moveable:'x', moveable:'y'resizeable {boolean} - should items be resizeable?resizerContent {string} - html content of the resizercollisionDetection {boolean} - block overlaping items when resizing / movingsnapStart {function} (timeStart: number, startDiff: number, item: object) => number; - function that will return new item time in miliseconds while moving - if you want snap to days - checkout examplesnapEnd {function} (timeEnd: number, endDiff: number, item: object) => number same as above but for end of item api.time.date(timeEnd+endDiff).endOf('day')ghostNode {boolean} - ghost node should be visible?wait {number} - sometimes you just want to click an item and sometimes you want to move it, this option will tell gstc to wait some time while mouse button is down to turn on moving mode to prevent accidental item move while clicking - time in milisecondsYou can also add moveable and resizeable option to each item so you will be able to block movement / resizing of some items or limit movement / resizing to specified axis.
When you need to move specified item only in some rows you can set item.moveable to array of row ids item.moveable = ['1','2','5'].
If you need to add some actions or want to be notified whenever any item is moving or resizing you can subscribe to config.plugin.ItemMovement like const unsubscribe = GSTCState.subscribe('config.plugin.ItemMovement', itemMovement => { /* do something with info */}).
const config = {
/*...*/
chart: {
items: {
'1': {
id: '1',
rowId: '1',
moveable: false, // NOT MOVEABLE
resizeable: false, // NOT RESIZEABLE
label: 'Item 1',
time: {
start: new Date('2020-01-01').getTime(),
end: new Date('2020-01-02').getTime()
}
},
'2': {
id: '2',
rowId: '2',
moveable: ['1'], // MOVEABLE ONLY WITHIN ROW '1'
resizeable: true, // RESIZEABLE
label: 'Item 2',
time: {
start: new Date('2020-01-01').getTime(),
end: new Date('2020-01-02').getTime()
}
},
'3': {
id: '3',
rowId: '2',
moveable: 'y', // MOVEABLE ONLY WITHIN Y AXIS
resizeable: true, // RESIZEABLE
label: 'Item 3',
time: {
start: new Date('2020-01-03').getTime(),
end: new Date('2020-01-04').getTime()
}
}
}
}
};
Example of adding style to currently resizing item:
class ResizingItemClassAction {
update(element, data) {
const hasClass = element.classList.contains('resizing');
if (data.item.isResizing && !hasClass) {
element.classList.add('resizing');
} else if (!data.item.isResizing && hasClass) {
element.classList.remove('resizing');
}
}
}
const config = {
/*...*/
actions: {
'chart-timeline-items-row-item': [ResizingItemClassAction]
}
/*...*/
};
let GSTCState = (window.state = GSTC.api.stateFromConfig(config));
// watch item movement plugin data and set isResizing property to an item for ResizingItemClassAction
GSTCState.subscribe('config.plugin.ItemMovement', itemMovement => {
if (!itemMovement || !itemMovement.item) return;
state.update(`config.chart.items.${itemMovement.item.id}.isResizing`, itemMovement.item.resizing);
});

ghostNode: false,
// snap item start time to start of the day
snapStart(time, diff, item) {
return api.time
.date(time)
.add(diff, 'milliseconds')
.startOf('day')
.valueOf();
},
// snap item end time to end of the day
snapEnd(time, diff, item) {
