A complete Event Booking Application using MERNG


### Rest API

- Stateless ,client independent API for data exchange.

- We always send all data back to the client from an endpoint.

- If we want some less data we'll need to create a new endpoint in backend or we'll send parameters for the data we need.

- GET/POST/PUT/... requests.

- Routes & Controllers.

### GraphQL API

- Stateless ,client independent API for data exchange with higher query flexibility.

- No problem here regarding queries (very flexible).

- Only POST requests for every type of request to one single endpoint.

- Operation definitions and Resolvers.

- graphQL is a typed language.

- Eg. Query Language

```

{

    query { //operation : type

        user{ //operation : endpoint

            name //requested fields

            age

        }

    }

}

```

### Operation types in GraphQL

- Query -- "for GET"

- Mutation -- "for POST/PUT/PATCH/DELETE"

- Subscription -- "setup realtime connection with sockets"

### Design

- Event booking API

1. Event - Create, Update, Delete, View(Read)

2. Users - Connected to events

   || Filters -- CreatedBy, Booked

   || BooksEvents, Cancel Booking

### Packages

- npm install --save express body-parser

- npm install --save-dev nodemon

- npm install --save express-graphql graphql

- npm install --save mongoose

- npm install --save bcryptjs

- npm install --save jsonwebtoken

### Run

- prod -- node app.js

- dev -- npm start(uses nodemon)

### To kill all node ports

- killall node

### Error Fixes

- if graphiql not working try on "http" instead of "https"

### Remember 

 

- Dates are passed via "new Date().toISOString()"

### CORS

 - remember to set CORS policy to server
