Using jQWidgets React Components with Create-React-App

What is Create-React-App


Many React developers wanted to have a React Enviroment where they can focus only on their code, having all the configuration files like webpack, babel, react pre set-up.
create-react-app comes in strong here. When you install it all the config files are hidden so you can start working on your application right away. Of course if you want to pull out all of the configuration files, then the eject command comes in. With it you can further tweak your configuration.


Installing Create-React-App


Assuming we already have node installed, run the following comamnd in our terminal:


$ npm install -g create-react-app


Creating an App


To create a new app, run the following command:


create-react-app my-app


It will create a directory called my-app inside the current folder. Inside that directory, it will generate the initial project structure and install the transitive dependencies:



No configuration or complicated folder structures, just the files you need to build your app.


Now in order to start the app, run the following command:


npm start


This runs the app in development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will see the build errors and lint warnings in the console.


Integrating jQWidgets React Components


  • Create jqwidgets-react folder inside the src folder and add the needed react_jqxXXXX.js files in it:

  • Create jqwidgets folder inside the public folder and add the needed jqxXXXX.js files in it:

  • Inside index.html file add the needed jqxXXXX.js references:

         
    <!doctype html>
    <html lang="en">
    <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <link rel="manifest" href="%PUBLIC_URL%/manifest.json">
    <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
    <title>React App</title>
    <!-- jQWidgets -->
    <link rel="stylesheet" href="./jqwidgets/styles/jqx.base.css" type="text/css" />
    <script type="text/javascript" src="./jqwidgets/jqxcore.js"></script>
    <script type="text/javascript" src="./jqwidgets/jqxdatetimeinput.js"></script>
    <script type="text/javascript" src="./jqwidgets/jqxcalendar.js"></script>
    <script type="text/javascript" src="./jqwidgets/jqxtooltip.js"></script>
    <script type="text/javascript" src="./jqwidgets/globalization/globalize.js"></script>
    </head>
    <body>
    <div id="root"></div>
    </body>
    </html>
  • Finally inside App.js file write your widget code:

     
    import React, { Component } from 'react';
    import JqxDateTimeInput from './jqwidgets-react/react_jqxdatetimeinput'
    class App extends Component {
    render() {
    return (
    <div>
    <h4>My First jQWidgets React Component</h4>
    <JqxDateTimeInput width={200} height={30} />
    </div>
    );
    }
    }
    export default App;

And here is the output:



Conclusion


So you’ve made your application with webpack, babel and everything else all figured out and installed for you. You just added the needed files, wrote some code and the application was ready to go! If you consider building a React application create-react-app is one of the best starter projects you can use.

Angular Grid

Angular Grid UI Component


jQWidgets Angular Grid is an advanced data grid user interface component built on top of Typescript, Angular and the jQWidgets framework. It is feature complete and is built by the same developers who implemented the best Javascript Grid – jqxGrid. With our Angular Grid, you can use the same API and functionalities.

GREAT PERFORMANCE


jqxGrid offers fast data updates on all end-user features such as grouping, sorting, paging, and scrolling. The Angular Grid also comes with row and column virtualization, which minimizes the amount of items that need to be rendered, and ensures unbeatable performance in spread-like scenarios with thousands of rows and columns.

UNIQUE FLEXIBILITY


jqxGrid is developed on top of the jQWidgets UI Framework and delivers a combination of unique features which can be easily enabled, disabled or customized. Our Angular Grid provides the ultimate flexibility over your data and its presentations including paging, grouping and sorting.

SORTING


The Angular Grid supports built-in powerful sorting capabilities like one-click automatic sorting, selection of sort option from a context menu, and sorting through APIs. The data grid automatically chooses the most appropriate comparison. Users can also implement and use a custom sort comparer. The sorting works well with all possible configurations including rows grouping and paging. Angular Grid also has an option to display an additional background in the sorted column.

Some of the other supported features by our Angular Grid are: Filtering, Paging, Grouping, Nested Grids, Pinned(Frozen) Columns, Conditional Formatting, Cells Editing, Row Editing, Data Validation and many more.


Lets start with a simple Angular Grid setup:

Template:
    <jqxgrid [width]="500" [source]="dataAdapter" [columns]="columns">
</jqxgrid>


Component:

    export class AppComponent {
//This generates some random array with data
data: any[] = generatedata(100);
source: any =
{
localdata: this.data,
datafields:
[
{ name: 'firstname', type: 'string' },
{ name: 'lastname', type: 'string' },
{ name: 'price', type: 'number' }
],
datatype: 'array'
};
dataAdapter: any = new $.jqx.dataAdapter(this.source);
columns: any[] =
[
{ text: 'First Name', datafield: 'firstname', width: 200 },
{ text: 'Last Name', datafield: 'lastname', width: 200 },
{ text: 'Unit Price', datafield: 'price', cellsalign: 'right', cellsformat: 'c2' }
];
}


As you can see we can either directly assign value to the property like with the width or we can use a property from our component class – source & columns.

And here is the result:

angular grid

Now let’s add some features to the Angular Grid:

    <jqxgrid [width]="500" [source]="dataAdapter" [columns]="columns"
[pageable]="true" [editable]="true" [filterable]="true" [autoheight]="true">
</jqxgrid>


The code in AppComponent stays the same(as above Component example), because we don’t have anything new we need from there. This looks like this:

Editing Feature:

angular grid editing

Paging Feature:

jQWidgets Angular Grid has integrated paging functionality that lets the users to view large data sets in multiple pages for faster loading and intuitive navigation. Users also have an option to select how many records they would like to see on a page by using a page-size dropdown. To navigate to a page, users can enter the page number in the page-input box and click the ‘enter’ key or they can click the ‘next’ and ‘previous’ navigation buttons to navigate to the next or the previous page.

angular grid paging

Filtering Feature:

angular grid filtering

Every event you have in the normal jqxGrid is available in Angular Grid too. All you need to do is write on before it and upperCase it’s first letter.

You bind it like this:

 <jqxgrid (onCellbeginedit)="cellBeginEditEvent($event)"
[width]="500" [source]="dataAdapter" [columns]="columns">
</jqxgrid>


The Angular Grid by jQWidgets is fast and easy to use. It works across devices and has a consistent look and behavior on PCs, tablets and mobile phones. It is a perfect solution for complex Angular UI applications.
