Installation

Prerequisites for the Dash0 Web SDK and an index of the setup, configuration, and API guides.

The SDK is currently distributed as an NPM package. We are considering adding more distribution formats in the future. Should you need a currently unavailable format, let us know by creating a GitHub issue or via support@dash0.com.

Before you begin

You'll need the following before you can start with the Dash0 Web SDK:

  • An active Dash0 account. Sign Up
  • An Auth Token; auth tokens for client monitoring will be public as part of your website, please make sure to:
    • Use a separate token, exclusively for website monitoring; if you want to monitor multiple websites, it is best to use a dedicated token for each
    • Limit the dataset permissions on the auth token to the dataset you want to ingest Website Monitoring data with
    • Limit permissions on the auth token to Ingesting
  • The Endpoint url for your dash0 region. You can find it via Organization Settings > Endpoints > OTLP via HTTP.

Documentation

Once you have the prerequisites above, follow these guides:

  • Setup — add the SDK via modules or script tags and initialize it, including Content Security Policy configuration.
  • Configuration — all init options: backend correlation and propagators, configuration auto-detection (Vercel, VCS context), website attributes, telemetry transmission, session tracking, error tracking, HTTP request and page-view instrumentation.
  • API — runtime API functions: addSignalAttribute, removeSignalAttribute, identify, sendEvent, reportError, terminateSession, and setActiveLogLevel.
