Info

This libary can be used to enhance the looplab/eventhorizon library with the functionality to trace the X-Correlation-ID through events.

Supported Go Versions:

This library supports two most recent Go, currently 1.16

Install

go get github.com/Clarilab/eh-tracygo

Usage

Get Correlation-ID from Context:

import (
    ehtracygo "github.com/Clarilab/eh-tracygo"
)

func someFunction(ctx context.Context) {
    correlationID := ehtracygo.FromContext(ctx)
}

Add Correlation-ID to Context:

import (
    ehtracygo "github.com/Clarilab/eh-tracygo"
)

func someFunction(ctx context.Context, correlationID string) {
    ctx = ehtracygo.NewContext(ctx, correlationID)
}

If the Correlation-ID is already present in the context, simply initialize this libary to use it in combination with the looplab/eventhorizon library.

import (
    _ "github.com/Clarilab/eh-tracygo"
)
