This is an example of custom-theme that can be applied for istance via an ng-class directive to the container of the library. In this way you are redefine some variables that are defined and used inside the library and it is easier to override some properties
.custom-theme {
--ngx-timeline-icon: black;
--ngx-timeline-period-inner-container: black;
--ngx-timeline-line-background: black;
}
<ng-template #periodCustomTemplate let-period=period let-index=index let-event=event>
<div [ngClass]="{'transparent first-line': !index}" class="line"></div>
<div class="period-container">
<p>
{{index}} - {{period | json }}
</p>
</div>
<div class="line"></div>
</ng-template>
<ng-template #centerIconCustomTemplate let-index=index let-event=event>
<div class="icon-container">
<img src="assets/image.png">
</div>
</ng-template>
<ng-template #innerEventCustomTemplate let-event=event>
<div class="event" (click)="handleClick(event)">
{{event | json}}
</div>
</ng-template>
<ng-template #eventDescriptionCustomTemplate let-event=event>
<p class="event-info-description">{{event?.eventInfo?.description}}</p>
</ng-template>
<ng-template #eventCustomTemplate let-event=event let-colSidePosition=colSidePosition>
<div class="event" (click)="handleClick(event)">
{{event | json}}
</div>
</ng-template>
<ng-template #dateInstantCustomTemplate let-item=item>
<span>
{{item | json}}
</span>
</ng-template>
First of all, in order to track everything, open an issue describing the problem or a missing functionality you would like to add to the lib.
To start the contribution:
-
npm run watch-lib
(you are building the lib with --watch options) -
npm run start-dev
(you are linking the lib and starting the demo app )
Every time you will change the code in your lib, any update will trigger the re-load of the app. When your code will be ready, create a Pull Request and put the link in a comment under the issue you opened before. Now is time to enjoy and start to code.
Thanks in advance for your contribution
After testing the fix or the new feature with 100% test coverage:
- npm run lint:fix
