Next.js Quickstart Guide

Installing the Freshpaint Javascript SDK in a Next.js application

Next.jsarrow-up-right is a popular front-end framework for building React-based applications optimized for server-side rendering (SSR) and static website generation. While we usually recommend using React's useEffectarrow-up-right hook as a way to initialize the Freshpaint SDKarrow-up-right, Next.js requires its own special approach to integrating Freshpaint with your application. Next.js provides a built in component called Scriptarrow-up-right that is used to add additional JavaScript to the page.

Below is an example of a Next.js component you might create to add the Freshpaint SDK to the page and initialize it for your site's Freshpaint environment.

import React from 'react'
import Script from 'next/script';

export default function FreshpaintSnippet() {
  return (
    <>
      <Script
        id="freshpaint-snippet"
        dangerouslySetInnerHTML={{
          __html: `
            (function(){function p(r,e){(e==null||e>r.length)&&(e=r.length);for(var t=0,a=new Array(e);t<e;t++)a[t]=r[t];return a}function v(r){if(Array.isArray(r))return p(r)}function h(r){if(typeof Symbol!="undefined"&&r[Symbol.iterator]!=null||r["@@iterator"]!=null)return Array.from(r)}function A(){throw new TypeError("Invalid attempt to spread non-iterable instance.\\nIn order to be iterable, non-array objects must have a [Symbol.iterator]() method.")}function I(r,e){if(r){if(typeof r=="string")return p(r,e);var t=Object.prototype.toString.call(r).slice(8,-1);if(t==="Object"&&r.constructor&&(t=r.constructor.name),t==="Map"||t==="Set")return Array.from(t);if(t==="Arguments"||/^(?:Ui|I)nt(?:8|16|32)(?:Clamped)?Array$/.test(t))return p(r,e)}}function y(r){return v(r)||h(r)||I(r)||A()}var E=function(r,e){if(!e.__SV){try{var t,a,m=window.location,c=m.hash,x=function(n,o){return t=n.match(new RegExp(o+"=([^&]*)")),t?t[1]:null};c&&x(c,"fpState")&&(a=JSON.parse(decodeURIComponent(x(c,"fpState"))),a.action==="fpeditor"&&(window.sessionStorage.setItem("_fpcehash",c),history.replaceState(a.desiredHash||"",r.title,m.pathname+m.search)))}catch(S){}e.__loaded=!1,e.config=!1,e.__SV=2,window.freshpaint=new Proxy(e,{get:function(n,o){return n[o]!==void 0?n[o]:o==="init"?function(l,u,i){var _,d;(_=n)[d="_i"]||(_[d]=[]),n._i.push([l,u||{},i||"freshpaint"])}:function(){for(var l=arguments.length,u=new Array(l),i=0;i<l;i++)u[i]=arguments[i];var _=[o].concat(y(u));return n.push(_),new Proxy(_,{get:function(f,w){return f[w]?f[w]:function(){for(var b=arguments.length,g=new Array(b),s=0;s<b;s++)g[s]=arguments[s];f.length=0,f.push([o].concat(y(u))),f.push([w].concat(y(g)))}}})}}})}};E(document,window.freshpaint||[]);})();
            freshpaint.init("YOUR FRESHPAINT ENVIRONMENT ID HERE");
            freshpaint.page();
          `
        }}
      />
      <Script src="https://freshpaint-cdn.com/js/YOUR FRESHPAINT ENVIRONMENT ID HERE/freshpaint.js" />
    </>
  )
}

Finding your Freshpaint Web snippet

The contents of each Script component's JavaScript source correspond to the two script tags found in the Freshpaint application under the Web integration of the Sources page at https://app.freshpaint.io/sourcesarrow-up-right. You should see the modal containing your Freshpaint snippets below by clicking the Configure button next to the Web integration:

:

Let's take a look at each Script component in more detail.

hashtag
The first Script component

In the code above, there are a few important things to note:

  1. Next.js requires that a unique id attribute be defined on any Script component that does NOT use the src attribute to reference a remote JavaScript source file. This must be defined or Next.js will not be able to properly render the script HTML element onto the page.

  2. The value of the prop dangerouslySetInnerHTML.__html comes from the first script tag in your Freshpaint environment's Web integration snippet (described in the section above).

hashtag
The second Script component

In the code above, the value of the src attribute comes from the second script tag in your Freshpaint environment's Web integration snippet (described in the section above).

Rendering the FreshpaintSnippet component in your Next.js application

The best location to render your new FreshpaintSnippet component in your Next.js application will depend upon what kind of Next.js application you are building, and the structure of your application. In general, we recommend rendering the FreshpaintSnippet component in one of the "root" components of your application. Your FreshpaintSnippet should only render onto the page one time, and should remain rendered on the page for the lifetime of your Next.js application.
