Hi everyone,
I am trying to implement PACT JS. Currently I am referring to this implementation :

npm install (or yarn install) and the consumer side command (mocha app/client/spec/PostServiceClient.spec.js) worked well.The pact file was generated.

But the provider side command (node app/service/spec/PostService.spec.js) failed.It's seemed due to the localhost server. But i didn't succeed in running the server. It missed 'THREE' module.

After adding 'THREE' module, i couldn't compile the build. So 2 files are missing in the repository main.js and Template.html (--> webpack.config.js). And i didn't succeed in posting a comment in Lucas M Blog (http://hecodes.com/2016/10/better-testing-microservices-using-consumer-driven-contracts-node-js/)

Could someone help me? Wilson Mahann

    Try posting code of the attempts so far along with any error messages. If the problem is about a github repository try opening an issue so the repository creator can clear things up. – Tristo Sep 20 '18 at 09:02
  • Hi Wilson, given you are taking an example project from someone anonymously from the internet, you're best first call is to raise an issue on their repository. If you like, there are multiple examples on the Pact JS project page to get started, which we can support you with if you had questions. – Matthew Fellows Sep 21 '18 at 13:43
  • Hi Matt, that what i finally decided to do. Thanks a lot to Tristo and you. – Wilson Mahann Sep 21 '18 at 15:07

So I had successfully the missing module "three" : yarn add three
And run the server

$ yarn server
    yarn run v1.9.4
    $ webpack-dev-server --host 0.0.0.0 --config webpack.config.js --devtool eval --progress --hot --inline

        Child html-webpack-plugin for "index.html":

            ERROR in Entry module not found: Error: Cannot resolve 'file' or 'directory' D:\Workspace\pact-js\js00\pact-node-example-master\app\template.html in D:\Workspace\pact-js\js00\pact-node-example-maste
        r\app
    webpack: Failed to compile.

Finally, i created main.js and Template.html files. And i succeeded in compiling but i dont know what code to implement in my files!!

Thanks a lot
