Steps to get started GraphQL - gqlgen

Download glggen using

go get  github.com/99designs/gqlgen

This will create boilerplate code for GraphQL using gqlgen

go run github.com/99designs/gqlgen init

In graph/schema.graphqls define schemas(structs in go), input schema, mutations(means post, put methods), queries(get methods) and do ref

make generate

Every time we add/modify any mutation or query or schema we need to do make generate so that gqlgen will update the dependencies code

After doing make generate we will have our mutations, queries code in graph/schema.resolvers.go, we can modify them according to our logic

Steps to run

make run

Currently our server is running at http://localhost:8080/#

Example mutuation createUser add the below thing

mutation CreateUser($userInput: NewUser!) {
  createUser(input: $userInput) {
    id,
    name,
    userName,
    email
  }
}

// in variables tab below

{
"userInput": {
  "name":"sergio ramos",
  "userName": "sr04",
  "email": "ramos@fmail.com"
}
}

Example query getUser

query GetUser($id: String!){
  getUser(input: $id){
    id,
    name,
    email
  }
}

// in variables tab below

{
"id": "suryacr7"
