Example Consumer

(latest pact)

This is an example of a Node consumer using Pact to create a consumer driven contract, and sharing it via PactFlow.

It is using a public tenant on PactFlow, which you can access here using the credentials dXfltyFMgNOFZAxr8io9wJ37iUpY42M/O5AIZWxelWbLvqMd8PkAVycBJh2Psyg1. The latest version of the Example Consumer/Example Provider pact is published here.

The project uses a Makefile to simulate a very simple build pipeline with two stages - test and deploy.

• Test
  • Run tests (including the pact tests that generate the contract)
  • Publish pacts, associating the consumer version with the name of the current branch
  • Check if we are safe to deploy to prod (ie. has the pact content been successfully verified)
• Deploy (only from master)
  • Deploy app (just pretend for the purposes of this example!)
  • Record the deployment in the Pact Broker

Usage

See the PactFlow CI/CD Workshop.

Running the application

Start up the provider (or another compatible provider) API by running npm run start.

Open a separate terminal for the consumer.

Before starting the consumer, create a .env file in the root of the project and set the URL to point to your running provider:

REACT_APP_API_BASE_URL=http://localhost:8080

Then run:

npm run start

Pre-requisites

Software:

• Tools listed at: https://docs.pactflow.io/docs/workshops/ci-cd/set-up-ci/prerequisites/
• A pactflow.io account with an valid API token

Environment variables

To be able to run some of the commands locally, you will need to export the following environment variables into your shell:

• PACT_BROKER_TOKEN: a valid API token for PactFlow
• PACT_BROKER_BASE_URL: a fully qualified domain name with protocol to your pact broker e.g. https://testdemo.pactflow.io

Usage

Pact use case

• make test - run the pact test locally
• make fake_ci - run the CI process locally
