Svelte and SvelteKit

Svelte + SvelteKit is a framework for building web applications of all sizes, with a beautiful development experience and flexible filesystem-based routing.

This guide covers setting up client-side Crash Reporting for an existing SvelteKit (or Svelte) application using the Raygun4JS provider. Server-side Crash Reporting is currently not supported by the Raygun4JS provider. However, if you are using SvelteKit and you are using the Node.js SvelteKit adapter for running server-side code (this is enabled by default) then you can use the Raygun Node.js npm package.

note: We highly recommend utilizing the CDN installation method for Raygun4JS. Alternative methods like NPM might necessitate additional manual setup, particularly when working with SvelteKit. Additionally, please be aware that SvelteKit offers certain automatic server-side rendering features that could potentially limit Raygun4JS's ability to capture all errors.

Package Manager
CDN

npm install raygun4js

yarn add raygun4js

bun add raygun4js

Import the Raygun4JS provider into your application inside of App.js (or equivalent for your framework) and enable Crash Reporting.

import rg4js from 'raygun4js';

rg4js('apiKey', 'paste_your_api_key_here');
rg4js('enableCrashReporting', true);

Add the following snippet to the beginning of the <head> tag within your markup, before any other <script> tags.

<script type="text/javascript">
  !function(a,b,c,d,e,f,g,h){a.RaygunObject=e,a[e]=a[e]||function(){
  (a[e].o=a[e].o||[]).push(arguments)},f=b.createElement(c),g=b.getElementsByTagName(c)[0],
  f.async=1,f.src=d,g.parentNode.insertBefore(f,g),h=a.onerror,a.onerror=function(b,c,d,f,g){
  h&&h(b,c,d,f,g),g||(g=new Error(b)),a[e].q=a[e].q||[],a[e].q.push({
  e:g})}}(window,document,"script","//cdn.raygun.io/raygun4js/raygun.min.js","rg4js");
</script>

Paste this snippet below the one you added in step 1.

<script type="text/javascript">
  rg4js('apiKey', 'paste_your_api_key_here');
  rg4js('enableCrashReporting', true);
</script>

Optional - Enable Real User Monitoring

Enable Real User Monitoring to also track your website's performance.

<script type="text/javascript">
    ...
    rg4js('enableRealUserMonitoring', true); // Enables Real User Monitoring
</script>

The provider is open source and available at the Raygun4js repository.
