add raw HTML with <script> inside Gatsby React page

I am trying to add an external embed code to my Gatsby page.

I currently use

import React from 'react'
import Link from 'gatsby-link'


let test ="<script type='text/javascript'>
(function(d, s) {
    var useSSL = 'https:' == document.location.protocol;
    var js, where = d.getElementsByTagName(s)[0],
    js = d.createElement(s);
    js.src = (useSSL ? 'https:' : 'http:') +  '//www.peopleperhour.com/hire/1002307300/1213788.js?width=300&height=135&orientation=vertical&theme=light&rnd='+parseInt(Math.random()*10000, 10);
    try { where.parentNode.insertBefore(js, where); } catch (e) { if (typeof console !== 'undefined' && console.log && e.stack) { console.log(e.stack); } }
}(document, 'script'));
</script>"

const ContactPage = () => (

    <div>
        <h1>ContactPage</h1>
        <div
            dangerouslySetInnerHTML={{ __html: test }}
          />
    </div>

)

export default ContactPage

which is full of syntax errors. Can you please point out a better way to include raw snippets in a react component?

Is there alternatively a place in Gatsby to add all additional scripts like custom scripts, Google Analytics, icon fonts, animate.js and anything else I may need?

Thank you for the help

You can inject external scripts (with no npm modules) to gatsby.js project in many ways. Prefer to use respective gatsby-plugin for "web-analytics" scripts.

Using require() :

  • Create a file in your project myScript.js and paste the script content
  • Add const myExtScript = require('../pathToMyScript/myScript')
    to a statefull component at the Pages folder inside render() and before return() if you want to execute that script only at that page(=page/component scope).

    export default class Contact extends React.Component {  
      render() {  
       const myExtScript = require('../pathToMyScript/myScript')  
        return (
          ........       
                   )}
    
  • If you want to execute script in the global scope (=in every page/ component):
    add it in html.js

    <script dangerouslySetInnerHTML= {{ __html: ` 
        putYourSciptHereInBackticks `}} />`  
    

    before closing the </body>. It is better to manipulate/monitor your global scope at this component because it has this specific purpose... to inject html to every page/route globally.

  • Another way to inject at the global scope is with require() before the component declaration. This will work but it's not a good practice, as your components shouldn't inject anything globally.

     const myExtScript = require('../pathToMyScript/myScript')  
    
       export default class Contact extends React.Component {  
        render() {  
          return (
          ........       
                   )}
