I am using react-icons and I have a JSON file as follows:
social: {
twitter: {
icon: 'FaTwitter',
link: 'twitterlink',
},
linkedin: {
icon: 'FaLinkedIn',
link: 'linkedinlink',
},
github: {
icon: 'FaGithub',
link: 'githublink',
},
}
I am trying to dynamically create the icons by looping through the JSON, but I'm having a lot of trouble making it work.
Here are snippets of what I've already tried so far along with the outputs and the errors produced in the console:
React Icons import
import * as FontAwesome from 'react-icons/lib/fa';

{Object.keys(social).map(key => {
let IconName = Component['FontAwesome.' + social[key].icon];
return (
<li key={key}>
<a href={social[key].link} target="_blank" rel="noopener">
<IconName size="15" />
</a>
</li>
);
})}
Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Warning:
<FontAwesome.FaTwitter />
is using uppercase HTML. Always use lowercase HTML tags in React.Warning: The tag
<FontAwesome.FaTwitter>
is unrecognized in this browser. If you meant to render a React component, start its name with an uppercase letter.
There are more errors but for FaLinkedIn
and FaGithub
which are the same.
Output in react dev tool
<li>
<a href="twitterlink" target="_blank" rel="noopener">

</a>
</li>
HTML output
<li>
<a href="twitterlink" target="_blank" rel="noopener">

What I want is something like this:
<FontAwesome.FaTwitter size="15" />

Is what I'm trying to do possible? Are there any workarounds or another way of doing it?
There are similar questions are StackOverflow but none seems to be working for me, that's why I asking a new one. I've also tried googling the errors but no luck there either.
Here is how to create react-icons
dynamically given the name of the icon:
import React from "react";
import { render } from "react-dom";
import * as FontAwesome from "react-icons/lib/fa";
const Icon = props => {
const { iconName, size, color } = props;
const icon = React.createElement(FontAwesome[iconName]);
return (
<div style={{ fontSize: size, color: color }}>{icon}</div>
);
};
Once you have this icon wrapper, just use it as a normal React component:<Icon iconName={"FaBeer"} size={12} color="orange" />
The icon name should follows MixedCaps
naming conversion.
