This marks another completion of an important milestone of `app-datepicker` with all the love from the [Web Components community][web-components-community-url] in making this element great and wonderful. As Web Components getting more and more traction and better at providing a web standard way of creating shareable components, it plays an important role in the JavaScript community as many developers depend on a plethora of development tools written in JavaScript for the web to create a better developer experience when developing a library, a component, or even a large scalable application. ![app-datepicker](https://user-images.githubusercontent.com/10607759/67633824-ce170c80-f8ef-11e9-8d20-856eb0e62409.jpg) Today, `app-datepicker` has been completely rewritten to adapt to the best of both worlds by leveraging the modern technologies the community most familiar with since year 2018. The following are the list of tools used that makes it shine: 1. [TypeScript] 2. [lit-element][lit-element-url] ## Table of contents  - [Pre-requisite](#pre-requisite) - [Installation](#installation) - [How to use](#how-to-use) - [Browser compatibility](#browser-compatibility) - [Q&A](#qa) - [API references](#api-references) - [Demo](#demo) - [Older versions](#older-versions) - [License](#license) ## Pre-requisite - [ES2019] _(The element is compiled with features targeting ES2019, so it might not work properly without transpilation on older browsers.)_ - [lit-element][lit-element-url] >= 2.2.1 - [OPTIONAL] [TypeScript] >= 3.8.3 _(TypeScript users only)_ ## Installation - NPM ```sh $ npm i app-datepicker ``` - Alternatively, it can be downloaded from any of the following awesome CDNs: 1. [jsdelivr (ESM)][jsdelivr-url] 2. [unpkg (ESM)][unpkg-url] ## How to use **Polyfills** Please make sure you have all these features available on the browsers you are supporting. If no, please consider polyfill-ing in order to run the datepicker element. * [Array.prototype.find] * [Intl.DateTimeFormat] The following snippet shows a simple script used in the demo to load polyfills via feature detection on different browsers: ```html <script> if (null == Array.prototype.find) { Object.defineProperty(Array.prototype, 'find', { value: function arrayFind(cb) { var filtered = this.filter(cb); return !filtered.length ? void 0 : filtered[0]; }, }); } if (!window.Intl) { var wa = document.createElement('script'); /** FIXME: Pin package version due to https://github.com/andyearnshaw/Intl.js/issues/256 */ wa.src = 'https://unpkg.com/intl@1.2.4/dist/Intl.complete.js'; wa.onload = function onLoad() { console.info('🌐 Intl polyfill loaded'); }; wa.onerror = console.error; document.head.appendChild(wa); } </script> ``` **my-app.ts** ```ts /** * Say you've already installed the element via NPM, simply import the package to your application. * Here I'm using `lit-element` for developing my application. */ import { css, customElement, html, LitElement } from 'lit-element'; import 'app-datepicker'; @customElement(MyApp.is) export class MyApp extends LitElement { static is() { return 'my-app'; } static styles = [ css` :host { display: block; } * { box-sizing: border-box; } ` ]; protected render() { return html`<app-datepicker></app-datepicker>`; } } ``` **index.html** ```html <!doctype html> <html>  <script type="module" src="/my-app.js"></script> ... <body> <my-app>  </my-app> </body> ... </html> ``` ## Browser compatibility Both `app-datepicker` and `app-datepicker-dialog` works in last 2 versions of all evergreen browsers (Chrome, Firefox, Edge, and Safari). Internet Explorer 11 is no longer supported in favor of the [new Microsoft Edge]. Tested on the following browsers: | Name | OS | | --- | --- | | Chrome 79 | Windows 10 | | Edge 18 | Windows 10 | | Firefox 72 | Windows 10 | | Safari 13 | mac 10.13 |  ## Q&A 1. Does it work well with [material-components-web-components]? For [material-components-web-components] users, you can create your own custom date picker element by wrapping `app-datepicker` inside [mwc-dialog].  ```ts // Simplified code snippet class MWCDatePicker extends LitElement { render() { return html` <mwc-dialog> <app-datepicker></app-datepicker> <mwc-button slot="secondaryAction" dialogAction="cancel">cancel</mwc-button> <mwc-button slot="primaryAction" dialogAction="set">set</mwc-button> </mwc-dialog> `; } } ``` 2. How can I hide the focus outline? For a11y reason, focus outline is shown when a calendar day is being focused. However, this can be modified via [CSS Shadow Parts]. ```css /** * Hide focus ring. * * NOTE: It is recommended to come up with alternative styling for focus state * instead of just hiding the focus ring. */ app-datepicker::part(calendar-day):focus { outline: none; } ``` ## API references - [AppDatepicker][app-datepicker-api-reference-url] - [AppDatepickerDialog][app-datepicker-dialog-api-reference-url] ## Demo [Configurable demo powered by Firebase] ## Older versions Meantime, feel free to check the older version out at: 1.
