OpenCensus Web Core (Trace Model)

For overview and usage info see the main OpenCensus Web readme.

This package combines contains the core trace model used by OpenCensus Web. This trace model is based on the same TypeScript interfaces that OpenCensus Node uses.

The library is in alpha stage and the API is subject to change.

Usage

Currently the primary intended usage of OpenCensus Web is to collect spans from the resource timing waterfall of an initial page load. See the OpenCensus Web readme for details.

In the future we would like to make it easy to generate custom spans that will be conveniently exported to the OpenCensus Agent. This package has the API that will support generation of custom spans. Although it's not fully wired up and supported yet, you're welcome to poke around the source code and try to use it!
