Read Me

This project is an experiment to see how well open tracing can work with graphql, express and objection/knex

Getting Started

Requirements

• node
• yarn
• docker and docker-compose

Setup

docker-compose up # To start jaeger
yarn install
yarn start

Server

Jaeger UI

Sample Query:

query PeopleQuery {
  people {
    name
  }
}

Open the graphql playground and excute the query a few times and then observe the spans created in jaeger

TODO

• Get every single span to log - Done using ConstSampler
• Retrieve spans in resolvers using GraphQLResolveInfo
• Types for opentracing
• Submit Opentracing types to definitely typed or enahnce npm package
• Figure out how to deal with parallel field resolution - Works I think...
• Add objection/knex integration
• Add joinmonster integration (This may be convered by field instrumentation)
• Test how it works with batch execution
