Building your app environment

Prerequisites

• Install node.js 16.0.
• If you have not previously installed the React packages or have an older version of node.js, you can run the following command to install them:
  npm install -g create-react-app

Step 1: Create a React app

To create a React app, you can execute the following command:

npx create-react-app my-app
cd my-app
npm start

or

yarn create react-app my-app
cd my-app
yarn start

To set up a React app in a TypeScript environment, run the following command:

npx create-react-app my-app --template typescript
cd my-app
npm start

Besides using the npx package runner tool, you can also create an app using the npm init command. To begin with the npm init command, upgrade the npm version to npm 6+:

npm init react-app my-app
cd my-app
npm start

Note: In the following demo, we’ll create a React app in a JavaScript environment.

Step 2: Adding Syncfusion React packages

Once you have created the React app, install the required Syncfusion React component packages. All Syncfusion React (Essential JS 2) packages are published on the NPM public registry. Choose the components you want to install.

In this demo, we’ll use the following Syncfusion React components to build our trading portfolio app:

• DataGrid Component
• Carousel Component
• DataManager
• Card Component
• DropDownList Component
• Sidebar Component
• ListView Component
• QueryBuilder Component
• Chart Component

To install the Syncfusion React packages, you can copy and paste them into your package.json file’s dependencies section.

{
  "name": "quickstart",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@syncfusion/ej2-base": "*",
    "@syncfusion/ej2-react-querybuilder": "*",
    "@syncfusion/ej2-data": "*",
    "@syncfusion/ej2-react-charts": "*",
    "@syncfusion/ej2-react-splitbuttons": "*",
    "@syncfusion/ej2-react-dropdowns": "*",
    "@syncfusion/ej2-react-grids": "*",
    "@syncfusion/ej2-react-navigations": "*",
    "@syncfusion/ej2-react-lists": "*",

     . . .
}

Step 3: Add CSS reference

After installing the Syncfusion component packages, import the required themes based on the components used. 

Syncfusion React components come with built-in themes that are available in the installed packages. You can adapt the React components based on the app style by referring to any built-in themes.

Since this app uses many components, we’ll refer to the common CSS file, which contains all the component CSS through CDN.

Ensuring seamless app implementation

Once you have completed all the initial setup, you can begin implementing the app step by step.

Step 1: Module overview

The app overview module is designed using various Syncfusion components to enhance functionality and user experience. It offers a detailed view of all available stocks and their information. Users can easily add stocks to their portfolios and filter them by category for better organization and navigation.

Refer to the following image.

The Syncfusion React components used in this module include:

• Grid: To efficiently display stock details and prices, featuring a command column for integrating custom buttons. This allows you to easily add stocks to your portfolios and analyze their performance.

• Sidebar: Designed as a convenient left-side navigation panel, making it easy to access various options.

• Multiselect: Allows selection of multiple stocks, dynamically displaying details within the grid view.

Step 2: Portfolio and module descriptions

In this module, the React Grid is used in the portfolio section to display the stocks selected by the user. The grid is populated with comprehensive stock details, including the company’s name, last price, daily change, percentage change, rating, high and low prices, and trading volume.

Additionally, a custom button is added to the grid using the Grid’s Command Column feature, enabling users to remove stocks from the portfolio and analyze stock performance. This functionality ensures that users can effectively manage and monitor their selected stocks while gaining detailed insights into each stock.

Refer to the following image.

If no stocks are added to the portfolio, the grid displays a clear and informative message: “Add companies to your wishlist from the overview section!“. This message directs users to the overview section to add stocks, ensuring the portfolio remains interactive and easy to navigate, even when no stocks are currently selected.

Refer to the following image.

Step 3: Smart stock picks module

It is designed to help users filter and identify stocks based on specific criteria, making it easier to manage portfolios and improve decision-making. This module incorporates the following Syncfusion React components:

React Query builder

• The React Query Builder enables advanced filtering by allowing users to define complex conditions.
• Logical operators like “AND” and “OR” can be used to create rules for fields such as Last Price, High, Rating, and more.
• This functionality allows precise filtering to align with individual preferences or investment strategies.

React Grid component

• Displays filtered results in a structured tabular format.
• Key details, including Company Name, Last Price, Change (1D and %), Rating, High, Low, and Volume, are neatly organized for easy analysis.
• The grid includes a command column with buttons for actions like adding stocks to a portfolio or viewing performance charts.

Step 4: Stocks analysis module

This module uses the React Charts to create interactive and customizable data visualizations. It supports a variety of chart types, including line, bar, pie, and candlestick charts, and is ideal for apps such as sales analysis, financial data representation, and performance monitoring.

The component is specifically used to display candlestick charts for tracking stock price movements across different timeframes (e.g., 1M, 3M, YTD). These charts highlight essential stock details, such as high, low, open, and close values, helping users easily identify trends.

Refer to the following image.

The component incorporates various technical indicators, such as EMA (Exponential Moving Average), SMA (Simple Moving Average), RSI (Relative Strength Index), and Bollinger Bands, aiding market pattern analysis and making informed decisions. Users can toggle these indicators on and off based on their preferences.

Refer to the following image.

Its interactive features, such as hover tooltips, provide detailed insights into individual data points with specific periods.

Refer to the following images.

Additionally, the export functionality allows users to download chart data in multiple formats (e.g., PNG, PDF, CSV), facilitating offline analysis and reporting.

Refer to the following image.

By integrating the React Charts component, the module ensures a seamless and visually rich experience for analyzing and tracking stock performance.

Step 5: Climbers/fallers module

This module helps investors monitor stock trends, enabling them to make strategic decisions about buying or selling shares. By analyzing climbers (stocks on an upward trend) and fallers (stocks on a downward trend), users can identify market opportunities and potential risks.

Using the React Grid component, we can display detailed information about climbers and fallers. The grid showcases key stock details such as company name, current price, percentage change, trading volume, and other relevant metrics. Its interactive features, including sorting and pagination, make it easy for users to customize the display and focus on stocks that align with their investment strategies.

Refer to the following image.

Step 6: Trending news module

The React Card component displays content in an organized and visually appealing manner, commonly used in dashboards, news feeds, product showcases, and portfolios.

The component enables users to integrate text, images, buttons, and links, making it highly adaptable to various apps. Its responsive design ensures optimal display across different devices, enhancing the user experience.

The Trending News module uses the React Card component to display key news highlights effectively. This component organizes information in a simple and visually appealing format, making it perfect for showing trending stock market updates.

Refer to the following image.

Step 7: Know more module

In this module, we have integrated the React Carousel component for a dynamic slideshow, showcasing images and context to enhance user engagement.

For this demo, the carousel showcases sample stock images as slides, serving as placeholders to demonstrate the component’s functionality. Each slide can include both an image and its related content, making it a versatile tool for presenting interactive and visually rich content.

The React Carousel component ensures a smooth and responsive slideshow experience, making it an excellent choice for displaying featured items, promotions, or other rotating content in a sleek and modern format.

Run the sample

To run the sample, execute the following command in your command prompt:

npm start
