Getting started with Angular Timeline component

15 Mar 20245 minutes to read

This section explains how to create a simple Timeline, and demonstrate the basic usage of the Timeline module in an Angular environment.

Dependencies

The list of dependencies required to use the Timeline module in your application is given below:

|-- @syncfusion/ej2-angular-layouts
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-layouts
    |-- @syncfusion/ej2-angular-base

Setup Angular environment

You can use Angular CLI to setup your Angular applications. To install Angular CLI use the following command.

npm install -g @angular/cli

Create an Angular application

Start a new Angular application using below Angular CLI command.

ng new my-app
cd my-app

Installing Syncfusion Timeline Package

Syncfusion packages are distributed in npm as @syncfusion scoped packages. You can get all the Angular Syncfusion package from npm link.

Currently, Syncfusion provides two types of package structures for Angular components,

1. Ivy library distribution package format
2. Angular compatibility compiler(Angular’s legacy compilation and rendering pipeline) package.

Ivy library distribution package

Syncfusion Angular packages(>=20.2.36) has been moved to the Ivy distribution to support the Angular Ivy rendering engine and the package are compatible with Angular version 12 and above. To download the package use the below command.

Add @syncfusion/ej2-angular-layouts package to the application.

npm install @syncfusion/ej2-angular-layouts --save

Angular compatibility compiled package(ngcc)

For Angular version below 12, you can use the legacy (ngcc) package of the Syncfusion Angular components. To download the ngcc package use the below.

Add @syncfusion/ej2-angular-layouts@ngcc package to the application.

npm install @syncfusion/ej2-angular-layouts@ngcc --save

To mention the ngcc package in the package.json file, add the suffix -ngcc with the package version as below.

@syncfusion/ej2-angular-layouts:"21.1.35-ngcc"

Note: If the ngcc tag is not specified while installing the package, the Ivy Library Package will be installed and this package will throw a warning.

Adding Timeline module

Import Timeline module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-layouts.

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";

// Import Syncfusion Timeline module from Timeline package.
import { TimelineModule, TimelineAllModule } from '@syncfusion/ej2-angular-layouts';

import { AppComponent } from "./app.component";

@NgModule({
  imports: [BrowserModule, TimelineAllModule, TimelineModule], // Registering EJ2 Timeline Module.
  declarations: [AppComponent],
  bootstrap: [AppComponent],
})
export class AppModule {}

Adding CSS reference

Add Timeline component’s styles as given below in style.css.

@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import '../node_modules/@syncfusion/ej2-layouts/styles/material.css';

Adding Syncfusion Timeline component

Modify the template in app.component.ts file with ejs-timeline to render the Timeline component.

import { Component } from "@angular/core";
import { StepModel, Timeline } from '@syncfusion/ej2-angular-layouts';

@Component({
  selector: "app-root",
  template: `<!-- To Render Timeline. -->
    <div>
        <ejs-timeline id="timeline"></ejs-timeline>
    </div>`,
})
export class AppComponent {
}

Adding Items

You can define Timeline items by using <e-item> tag directive.

import { Component } from "@angular/core";

@Component({
  selector: "app-root",
  template: `<!-- To Render Timeline. -->
    <div>
        <ejs-timeline id="timeline">
          	<e-items>
                <e-item></e-item>
                <e-item></e-item>
                <e-item></e-item>
                <e-item></e-item>
            </e-items>
        </ejs-timeline>
    </div>`,
})
export class AppComponent {
}

Running the application

Run the application in the browser using the following command:

ng serve

The following example shows a default Timeline component.

app.component.ts

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css'],
})
export class AppComponent {
   
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

// Import Syncfusion Timeline module from layouts package.
import {  TimelineModule, TimelineAllModule } from "@syncfusion/ej2-angular-layouts";

import { AppComponent } from './app.component';

/**
 * Module
 */
@NgModule({
    //declaration of ej2-angular-layouts module into NgModule
    imports: [BrowserModule, TimelineModule, TimelineAllModule ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

app.component.html

<div class="container" style="height: 330px;margin-top: 30px;">
    <ejs-timeline id="timeline">
        <e-items>
            <e-item></e-item>
            <e-item></e-item>
            <e-item></e-item>
            <e-item></e-item>
        </e-items>
    </ejs-timeline>
</div>
