How to map JSON data in React?

If you wanted to, you could try to reverse-engineer the DOM on that website. Here is the general flow of the DOM on that site:

Files:

• App.jsx
  • icon_data.json
  • ResultContainer.jsx
    • ResultRow.jsx
      • ResultTitle.jsx
      • ResultList.jsx
        • ResultIcon.jsx

Here is a forkable snippet of the code below:

https://codesandbox.io/s/react-icon-mapping-qfsp5?file=/src/App.jsx

icon_data.json

[
  {
    "family": "AntDesign",
    "names": ["stepforward", "stepbackward", "forward", "backward"]
  },
  {
    "family": "Entypo",
    "names": ["500px", "500px-with-circle", "add-to-list", "add-user"]
  }
]

App.jsx

import React, { useEffect, useState } from "react";
import iconData from "./icon_data.json";
import ResultContainer from "./ResultContainer";

const fetchIconData = () => Promise.resolve(() => iconData);

const App = () => {
  const [data, setData] = useState([]);

  useEffect(() => {
    fetchIconData().then((jsonData) => setData(jsonData));
  }, []);

  return <ResultContainer data={data} />;
};

export default App;

ResultContainer.jsx

import React from "react";
import PropTypes from "prop-types";
import ResultRow from "./ResultRow";

const ResultContainer = (props) => {
  const { data } = props;

  return (
    <>
      {data.map(({ family, names }) => {
        return <ResultRow title={family} icons={names} />;
      })}
    </>
  );
};

ResultContainer.propTypes = {
  data: PropTypes.array.isRequired
};

export default ResultContainer;

ResultRow.jsx

import React from "react";
import PropTypes from "prop-types";
import ResultTitle from "./ResultTitle";
import ResultList from "./ResultList";

const ResultRow = (props) => {
  const { title, icons } = props;

  return (
    <div className="Result-Row">
      <ResultTitle title={title} />
      <ResultList icons={icons} />
    </div>
  );
};

ResultTitle.propTypes = {
  title: PropTypes.string.isRequired,
  icons: PropTypes.array.isRequired
};

export default ResultRow;

ResultTitle

import React from "react";
import PropTypes from "prop-types";

const style = {
  background: "#F66667",
  color: "#FFFFFF",
  padding: "1em",
  margin: "0"
};

const ResultTitle = (props) => {
  const { title } = props;

  return (
    <h2 className="Result-Title" style={style}>
      {title}
    </h2>
  );
};

ResultTitle.propTypes = {
  title: PropTypes.string.isRequired
};

export default ResultTitle;

ResultList.jsx

import React from "react";
import PropTypes from "prop-types";
import ResultIcon from "./ResultIcon";

const style = {
  display: "flex",
  flexDirection: "row"
};

const ResultList = (props) => {
  const { icons } = props;

  return (
    <div className="Result-List" style={style}>
      {icons.map((icon) => (
        <ResultIcon name={icon} />
      ))}
    </div>
  );
};

ResultList.propTypes = {
  icons: PropTypes.array.isRequired
};

export default ResultList;

ResultIcon.jsx

import React from "react";
import PropTypes from "prop-types";

const containerStyle = {
  display: "flex",
  flexDirection: "column",
  flex: 1,
  justifyContent: "center",
  padding: "0.5em",
  outline: "thin solid rgb(238, 238, 238)"
};

const iconStyle = {
  fontWeight: "normal",
  fontSize: "2em",
  textAlign: "center"
};

const titleStyle = {
  fontSize: "smaller",
  fontWeight: "normal",
  textAlign: "center",
  margin: "0"
};

const ResultIcon = (props) => {
  const { name } = props;

  return (
    <div className="Result-Icon-Container" style={containerStyle}>
      <span className="Result-Icon" style={iconStyle}>
        ☺
      </span>
      <h4 className="Result-Icon-Name" style={titleStyle}>
        {name}
      </h4>
    </div>
  );
};

ResultIcon.propTypes = {
  name: PropTypes.string.isRequired
};

export default ResultIcon;
