We know why a component library makes development easier and how to start our own. Now let’s see how to use a professional component library to make every step of our app development better and easier.

In previous articles, we learned how to create a component library in Angular, and then how to theme it and publish it to npm. However, our library only contained the button component. Real-world applications require a vast array of components like charts, grids and calendars.

Today, with the pressures of work volume and time-to-market, speed is of the essence. Creating these components and ensuring they cover all features is an enormous task.

Should your company need to provide more components and adhere to important market standards such as internationalization, accessibility, customization and performance, the workload can become overwhelming. If the development team needs to cover all these aspects, it could impact development speed, time-to-market and, in the worst-case scenario, cause burnout within your team.

What if I told you that you could supercharge your company library with more than 100+ components, including theme support and internationalization, in just a few minutes?

Indeed, you can enhance your company library with Kendo UI for Angular, putting the heavy workload onto the Progress Kendo UI team. You only need to pick the components required by your company to create a lightweight library.

Note: This article is part of the “Angular Component Library” series.

Let’s explain how to add Kendo UI into our Angular library with a practical scenario.


The consumers of the ngx-banana library need a beautiful calendar, but we don’t have time to build and create a powerful calendar. Let’s make it easy by integrating Kendo UI for Angular into our library.

First, we’ll embed Kendo UI for Angular as part of our library and configure it in the library module. Instead of building all the components from scratch, we’ll reuse Kendo UI components to provide all these features. Since Kendo UI for Angular is flexible, we install the minimum number of components required for our needs.

Create Banana Calendar with Kendo Power

Let’s begin by cloning our ngx-banana-ui library and opening it in your preferred code editor.

git clone
Cloning into 'ngx-banana'...

remote: Counting objects: 100% (98/98), done.
remote: Compressing objects: 100% (65/65), done.

Receiving objects: 100% (98/98), 211.32 KiB | 1.92 MiB/s, done.
Resolving deltas: 100% (36/36), done.

The first step in our journey is to install the necessary dependencies for the calendar:

npm install --save @progress/kendo-angular-dateinputs @progress/kendo-angular-intl @progress/kendo-angular-l10n @progress/kendo-angular-popup @progress/kendo-angular-common @progress/kendo-licensing @progress/kendo-angular-icons --legacy-peer-deps

Following that, it’s time to add some style to our components. For this purpose, we’ll install one of the available Kendo UI themes, specifically the Kendo UI Default theme:

npm install --save @progress/kendo-theme-default

Let’s create the calendar component, first, inside the components directory (projects/ngx-banana-ui/src/lib/components):

Because the prefix of library is banana , rename the selector to banana-calendar.

import {Component, Input} from '@angular/core';
selector: 'banana-calendar',
templateUrl: './banana-calendar.component.html',
styleUrls: ['./banana-calendar.component.css']
export class BananaCalendarComponent {
@Input() value = '12/12/2026';

Moving onto the ngx-banana-ui.module (which can be found inside projects/ngx-banana-ui/src/lib/ngx-banana-ui.module.ts), there are two primary tasks we need to accomplish:

  1. Add the banana-calendar to the declarations and exports. This step allows consumers to gain access to the new banana-calendar.
  2. Import the CalendarModule from Kendo UI.

Don’t forget to export the component in the public-api.ts file!

Upon importing the KendoCalendar module, we now have access to the kendo-calendar component. Open the banana-calendar.component.html file and start using the kendo-calendar.

Let’s start our banana-calendar component off by using Kendo UI’s calendar as our base. We can introduce some flexibility and bind the value property with the calendar. The final code should look something like this:

<kendo-calendar [value]="value"></kendo-calendar>

Lastly, import the calendar styles into our theme.scss file.

@import "@progress/kendo-theme-default/scss/index";

Build and Publish the Library

To build and publish the library, we are going to take some steps to make our library light and hide Kendo from package dependecies the ngx-banana-ui customers.

First open the ngx-banana-ui package.json file and update the version number, for example, to “1.3.4”.

Next, copy all the dependencies that Kendo installed in projects/package.json to projects/ngx-banana-ui/package.json into the new section “peer dependencies”:

Peer dependencies in a npm library offer multiple advantages: avoiding version conflicts, reducing bundle size, providing flexibility for consumers to choose compatible versions and simplifying maintenance. Learn more about peer dependencies.

Ensure that you are at the root of the project ngx-banana/ and compile the library by running the command npm run build ngx-banana-ui.

npm run build ngx-banana-ui

After that, navigate to the dist directory and publish the library using the npm publish command, similar as we did in the “Angular Component Library Part 2: How to Theme and Publish Your Library to npm” article.

To publish your library requires an npm account. Run the command npm adduser and follow each step.

Perfect! We have our library ready; the final step is to use it in our project!

Using the Library

To integrate the enhanced library into your workflow, we first establish a new project environment. You can achieve this using the Angular CLI with the command: ng new lab to initialize a new Angular workspace and a default application in a new directory, lab.

ng new lab

Next, integrate the ngx-banana-ui library into your new project by installing it through your package manager. With npm, it would look like this: npm install ngx-banana-ui. This command tells npm to download the library package and add it to your node_modules directory.

Following this, you’ll want to ensure your application has access to the style assets of the library.

Open your style.scss file and import the theme from the library. This makes all the CSS classes available for you to use throughout your application.

Now, let’s ensure the NgxBananaModule is available to the rest of the application. Head over to your App.Module file and import the NgxBananaModule. By including it in the imports array of @NgModule, all the exported components and services in the NgxBananaModule are available to your application.

Because The Kendo Calendar uses the @angular/localize, we must install the package.

ng add @angular/localize
ℹ Using package manager: npm
✔ Found compatible package version: @angular/localize@15.2.9.
✔ Package information loaded.
The package @angular/localize@15.2.9 will be installed and executed.
Would you like to proceed? Yes
✔ Packages successfully installed.
UPDATE src/main.ts (266 bytes)
UPDATE (310 bytes)
UPDATE tsconfig.spec.json (315 bytes)

Finally, you can use the banana-component in any component of your application. Include its selector in the HTML template of your component, and ngx-banana will handle the rest, providing a powerful calendar component, all thanks to Kendo UI!

  <h2>Please pick your birthday</h2>
  <banana-calendar  [value]="'12/12/2022'"></banana-calendar>

After saving the changes, serve your application with ng serve and enjoy the fruits of your labor—a powerful, fully styled calendar component.
