CDN browser SDK installation guide
As part of our Real User Monitoring (RUM) toolkit, Coralogix offers multi-faceted Error Tracking, enabled by our CDN RUM Browser SDK.
Overview
Using a CDN RUM browser SDK enables quick and efficient deployment of monitoring tools by simply embedding a script tag in your HTML, without needing to install packages or set up a build system. This approach offers significant advantages: it minimizes setup time, leverages globally distributed CDN infrastructure for low-latency script loading, and benefits from browser-level caching, which can reduce load times and improve performance. Additionally, it allows developers to integrate RUM into static or legacy sites without major codebase changes, making it a convenient solution for capturing real-world user performance and behavior data with minimal effort.

Configuration
Select the exact version required for your use case.
Specific version (recommended)
By default, the CDN is built using the ES2015 (ES6) standard.
Use a specific browser version (https://cdn.rum-ingress-coralogix.com/coralogix/browser/[version]/coralogix-browser-sdk.js). Replace [version] with a version from our Releases page.
The latest CDN version option is no longer available. Use an explicit version instead.
ES5-compatible version
For legacy environment support, ensure you're using the ES5-compatible version (https://cdn.rum-ingress-coralogix.com/coralogix/browser/[version]/coralogix-browser-sdk.es5.js).

// In case of warning from TSC
declare global {
interface Window {
CoralogixRum: CoralogixOtelWebType;
}
}
