add raw HTML with <script> inside Gatsby React page

Question

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 (       ........                       )}
