Example Consumer
Source Code​
https://github.com/pactflow/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/

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 PactFlowPACT_BROKER_BASE_URL: a fully qualified domain name with protocol to your pact broker e.g. https://testdemo.pactflow.io
