Apollo Tracing (for Node.js)

This package is used to collect and expose trace data in the Apollo Tracing format.

It relies on instrumenting a GraphQL schema to collect resolver timings, and exposes trace data for an individual request under extensions as part of the GraphQL response.

This data can be consumed by Apollo Studio (previously, Apollo Engine and Apollo Graph Manager) or any other tool to provide visualization and history of field-by-field execution performance.

Usage

Apollo Server

Apollo Server includes built-in support for tracing from version 1.1.0 onwards.

The only code change required is to add tracing: true to the options passed to the ApolloServer constructor options for your integration of choice. For example, for apollo-server-express:

const { ApolloServer } = require('apollo-server-express');

const server = new ApolloServer({
  schema,
  tracing: true,
});
