Getting started

Prerequisites.

• NodeJS (10.x)
• Apollo CLI (npm i -g apollo)
• MySQL (Datasource I used for demo, you can use any datasource, typeorm supports)

Launching the app will create the schema. Please execute the schema.sql file, if you want some mock records, I played in demo.

Conference REST API

This project explains the NestJS architecture and how we implement the REST Apis for our conference demo.

cd conference-rest-api
npm run start

Navigate to http://localhost:3000/docs for swagger docs.

Conference GraphQL API

This project explains how to implement graphql api in NestJS for our conference demo.

Note: To setup the engine, you need your apollo engine api key.

Get your API Key

Log into Apollo Engine via your browser and create a service to get an API key.

Update the API key in your .env file. You can refer the .env schema in .env-sample

cp .env-sample .env

Update the ENGINE_API_KEY value with your api key received from your apollo engine.

cd conference-graphql-api
npm run start

Navigate to http://localhost:3000/graphql for graphql playground.

Conference GraphQL Client

This project implements apollo graphql client in Angular for our conference demo, that talks with GraphQL server.

Start the graphql server before you start the client. This client proxies the server request at http://localhost:4200/, the same port running client.

cd conference-graphql-client
ng serve --proxy-config proxy.conf.json
