Unlocking the Power of Data Analytics with React and Cube.js
In today’s data-driven world, making informed decisions requires the ability to collect, analyze, and visualize complex data. This is where data analytics and visualization come into play. By leveraging data visualization tools and technologies, we can transform massive amounts of information into actionable insights.
Building an Analytics App with React and Cube.js
In this article, we’ll explore how to build a robust analytics app using React and Cube.js. Our app will monitor raw product data from a database connected to a React dashboard through Cube.js, providing valuable insights into product sales and customer behavior.
What is Cube.js?
Cube.js is an open-source analytics platform that enables users to create a semantic API layer on top of their data. This allows for seamless access control, data aggregation, and caching. As a visualization-agnostic platform, users can build frontends with any framework or library of their choice.
Getting Started with React and Cube.js
Before we dive in, make sure you have a basic understanding of React, PostgreSQL, and Recharts. Also, note that all commands in this article are run on Linux, so command variations may differ for Windows and Mac users.
Setting Up the PostgreSQL Database
To store and retrieve analytics data, we’ll use PostgreSQL as our database. Let’s download and install PostgreSQL, then create a new database called “ecom.”
Populating the Database with Data
With our database set up, we can populate it with an ecommerce sample dataset. This dataset will be used later when we configure our Cube.js service.
Configuring Cube.js
To scaffold our Cube.js project, we’ll run a few commands to set up our project and connect it to our PostgreSQL database. We’ll also add our database credentials to the .env file and generate our data schema using the Cube.js Developer Playground.
Building the React App
Finally, we’ll connect our Cube.js backend to our React app using the @cubejs-client/core and @cubejs-client/react packages. We’ll import these packages into our Analytics.js file and use the useCubeQuery Hook to execute our query and retrieve the data.
Visualizing the Data
With our data in hand, we can now visualize it using Recharts’ BarChart component. We can also explore other visualization options, such as LineChart, AreaChart, or PieChart.
Taking it to the Next Level
While this tutorial focuses on using PostgreSQL as our database, we can easily switch to other databases like MongoDB. Additionally, we can utilize other visualization packages like D3.js or Charts.js to create custom visualizations.
