React Tech Radar

A react component that generates an interactive radar, inspired by thoughtworks.com/radar.

Installation

Using npm:

npm install --save react-tech-radar

Quick Start

import React from "react";
import Radar from "react-tech-radar";

function App() {
  const setup = {
    rings: ["adopt", "trial", "assess", "hold"],
    quadrants: ["tools", "techniques", "platforms", "languages"],
    data: [
      {
        name: "D3",
        quadrant: "tools",
        ring: "assess",
      },
      {
        name: "TypeScript",
        quadrant: "languages",
        ring: "trial",
      },
      {
        name: "Storybook",
        quadrant: "tools",
        ring: "adopt",
      },
    ],
  };

  return (
    <div className="App">
      <Radar {...setup} />
    </div>
  );
}

export default App;

Props Setup

The following 3 props should be configured in order to setup the tech radar:

• quadrants
• rings
• data || blips

data

data prop is an array of JSON elements representing the description of technologies.

Elements in the array should be in the following form:

Example:

{
  data: [
    {
      name: "D3",
      quadrant: "tools",
      ring: "assess",
    },
    {
      name: "TypeScript",
      quadrant: "languages",
      ring: "trial",
    },
    {
      name: "Storybook",
      quadrant: "tools",
      ring: "adopt",
    },
  ],
}

quadrants

quadrants prop is an array of strings which represent slices of the circular radar. Any data element with the matching quadrant value goes into this slice

Elements in the array should be in the following form:

Example:

{
  quadrants: ["tools", "techniques", "platforms", "languages"],
}

rings

rings prop is an array of strings which represent at what level these technologies are adopted. For each element in rings, every quadrant is divided into rings. Innermost ring is the first element of the rings array and it usually represents the place for the most adopted technologies.

Example:

{
  rings: ["adopt", "trial", "assess", "hold"],
}

Configuration Options

Prop	Description	Default Value
width	The overall width of the main DOM element	700px
fontSize	Font size of elements	12px
itemFontSize	Set this if you want the items to have a different size than titles of quadrants and rings. If not set, defaults to fontSize	12px
colorScaleIndex	A value from 0 to 5 for different collections of colors. See Storybook Color Schemes section for colors of each option.	5
radiusDiminish	Radius of rings is not equal because of this constant. Each radius is x times greater than the outer one and x is this constant.	1.5
