I have open source library that I want to use. the library wrote in clean vanilla js: follow their docs, if I want to use the library:
<html>
<head>
<script src="./jquery-2.0.3.min.js"></script>
<script src="./kinetic-v5.1.0.min.js"></script>
<script src="./inchlib-1.2.0.js"></script>
<script>
$(document).ready(function() { //run when the whole page is loaded
var inchlib = new InCHlib({"target": "inchlib",
"width": 800,
"height": 1200,
"column_metadata_colors": "RdLrBu",
"heatmap_colors": "RdBkGr",
"max_percentile": 90,
"middle_percentile": 60,
"min_percentile": 10,
"heatmap_font_color": "white",
text: 'biojs'});
inchlib.read_data_from_file("/microarrays.json");
inchlib.draw();
inchlib.onAll(function(name){
console.log(name + " event triggered");
});
});
</script>
</head>
<body>
<div class="heatmaps" style="margin:auto; align-items: center; margin-left:25%;">
<div id="inchlib"></div>
</div>
<div ></div>
</body>
</html>
The file inchlib-1.2.0.js contains the main logic and js code. I want to build react project and use this library there. How can I achieve this goal?
import React, { Component } from 'react';
import './App.css';
export default class App extends Component {
render () {
return (
<div>
<div>
</div>
</div>
)
}
}

- so you don't need a jquery you need to fire inchlib at the page load or the library require jquery to work ? – abdoutelb Commented Dec 26, 2020 at 18:10

Reset to default 2You can create custom hook with useEffect. In useEffect you should paste your code. You can insert html elements, add event listeners and so on.
useLibrary.js
import { useEffect } from "react";
const useLibrary = () => {
useEffect(() => {
$.getScript("inchlib-1.2.0.js", function(){
var inchlib = new InCHlib({"target": "inchlib",
"width": 800,
"height": 1200,
"column_metadata_colors": "RdLrBu",
"heatmap_colors": "RdBkGr",
"max_percentile": 90,
"middle_percentile": 60,
"min_percentile": 10,
"heatmap_font_color": "white",
text: 'biojs'});
inchlib.read_data_from_file("/microarrays.json");
inchlib.draw();
inchlib.onAll(function(name){
console.log(name + " event triggered");
});
});
}, []);
};
export default useLibrary;
App.js
import useLibrary from ".useLibrary";
export default class App extends Component {
useLibrary();
render () {
return (
<div>
<div class="heatmaps" style="margin:auto; align-items: center; margin-left:25%;">
<div id="inchlib"></div>
</div>
</div>
)
}
}But I warn you that this is a big crutch.
Depends on what you're gonna do with the library you want to integrate with. Checkout this as a base reference: Integrating with other libraries.
If you're gonna manipulate DOM elements you'll gonna need a reference to them. In this case checkout this: Refs and the DOM.
If the library provides some general logic, you have no problem using it anywhere throughout your code or more specifically in effects.
As inchlib is a visual element library, you'll need to go the first route and get a reference to a specific DOM element. As already noted, checkout Refs from react docs.
Alternative solution is to wrap the whole library usage in your own react ponent.
Well If I were to do the same thing then I would paste the script tags as you've done in your html file
<head>
<script src="./jquery-2.0.3.min.js"></script>
<script src="./kinetic-v5.1.0.min.js"></script>
<script src="./inchlib-1.2.0.js"></script>
<script>
</head>
For accessing an object into react app, Create a file named Inchlib.js in same directory as is your app.js
Contents of Inchlib.js should be
export default window.InCHlib;
Import the default export into your app.js
import InCHlib from "./inchlib";
function App() {
console.log(InCHlib); // prints the InCHlib object
return "hello";
}
Note: Although this should work, there might be a better way to do this. Also using global objects in react code is not usually a preferred option.
Hopefully this would help.
Just add the Libraries and Scripts you want in the public/index.html file in your react project.
create loadScript function:
function loadScript(src, position, id) {
if (!position) {
return;
}
const script = document.createElement('script');
script.setAttribute('async', '');
script.setAttribute('id', id);
script.src = src;
position.appendChild(script);
}
in Component:
export default function GoogleMaps() {
const loaded = React.useRef(false);
if (typeof window !== 'undefined' && !loaded.current) {
if (!document.querySelector('#google-maps')) {
loadScript(
'https://maps.googleapis./maps/api/js?key=AIzaSyBwRp1e12ec1vOTtGiA4fcCt2sCUS78UYc&libraries=places',
document.querySelector('head'),
'google-maps',
);
}
loaded.current = true;
}
}
now you can access window.google
here is a example
