How to Create Interactive Visualizations with Flitter

Aug 18, 2021 | Programming

Welcome to the world of Flitter, a powerful JavaScript rendering engine that combines the best of both performance and versatility. Inspired by the structure of Flutter, Flitter supports both SVG and Canvas to bring your web applications to life with high-performance graphics and user interfaces.

Getting Started with Flitter

Before diving into creating stunning visualizations, you need to get Flitter up and running. Below are installation methods for various environments.

Installation Guide

Pure JavaScript

To install Flitter in a pure JavaScript environment, use the following command:

bash
npm install @meursyphus/flitter

Then, set up your HTML structure and JavaScript code as follows:

javascript
import Container from '@meursyphus/flitter';

document.querySelector('#app')!.innerHTML = `
`; const app = new AppRunner({ view: document.querySelector('#view')!, }); app.onMount({ resizeTarget: document.querySelector('#container')!, }); app.runApp(Container({ color: 'lightblue' }));

React

For React applications, you can install Flitter using:

bash
npm install @meursyphus/flitter @meursyphus/flitter-react

Then import the components:

javascript
import Container, { Alignment, Text, TextStyle } from '@meursyphus/flitter';
import Widget from '@meursyphus/flitter-react';

const App = () => (
  
);

Svelte

To use Flitter with Svelte, run:

bash
npm install @meursyphus/flitter @meursyphus/flitter-svelte

And set up your Svelte component as follows:

sveltescript
import Container, { Alignment, Text, TextStyle } from '@meursyphus/flitter';
import Widget from '@meursyphus/flitter-svelte';

script
  Widget({
    width: '600px',
    height: '300px',
    renderer: 'canvas', // or svg
    widget: Container({
      alignment: Alignment.center,
      color: 'lightblue',
      child: Text("Hello, Flitter SVG!", {
        style: TextStyle({ fontSize: 30, weight: 'bold' }),
      }),
    }),
  });

Using Flitter: A Code Analogy

Think of Flitter as a talented chef in a busy restaurant, where the dishes being prepared are your visualizations. Just as a chef sorts ingredients and uses kitchen tools to create culinary masterpieces, Flitter organizes graphic elements using its render object tree and advanced rendering pipeline.

The chef carefully updates the menu as ingredients change, similar to how Flitter employs declarative programming. Each dish is only altered in response to customer (or user) feedback, optimizing the dining experience without unnecessary effort. This ensures that even complex dishes—like intricate data visualizations—are served efficiently and deliciously!

Creating a Simple Chart with Flitter

Here’s a quick example of how you can set up a simple bar chart using Flitter:

javascript
import Container, { Column, Text, SizedBox, Row } from '@meursyphus/flitter';

export default function BarChart() {
  return Container({
    alignment: Alignment.center,
    color: 'lightgrey',
    child: Column({
      mainAxisSize: 'min',
      crossAxisAlignment: 'center',
      children: [
        Text("BarChart", { style: { fontFamily: 'Intent', fontWeight: 600 } }),
        SizedBox({
          width: 200,
          height: 150,
          child: Row({
            mainAxisAlignment: 'spaceBetween',
            children: [
              { label: 'S', value: 60 },
              { label: 'M', value: 20 },
              { label: 'T', value: 30 },
              { label: 'W', value: 90 },
              { label: 'T', value: 70 },
              { label: 'F', value: 50 },
              { label: 'S', value: 40 },
            ].map((n) => new Bar(n.label, n.value)),
          }),
        }),
      ],
    }),
  });
}
class Bar extends StatefulWidget {
  constructor(label, value) {
    super();
    this.label = label;
    this.value = value;
  }

  createState() {
    return new BarState();
  }
}
class BarState extends State {
  // Animation logic...
}

Troubleshooting Your Flitter Set-Up

If you encounter issues while installing or using Flitter, consider the following troubleshooting tips:

  • Check that you have the correct version of Node.js installed.
  • Ensure that your project correctly imports all necessary Flitter components.
  • Verify your rendering settings—SVG or Canvas should be specified appropriately.
  • Review your HTML layout to ensure the container sizes are set as required.
