Express GraphQL playground

This just to run an Express GraphQL client which uses proxy to call the go graphql server. Just an easy hack to show beautiful user interface.

Pre-Requisites

Nodejs and NPM

How it works

cd examples/playground
npm install

go run main.go

Complex Sample

modify PLAYGROUND_PORT or GRAPHQL_PORT if you want:

// main.go
cmd.Env = append(os.Environ(),
  fmt.Sprintf("GRAPHQL_PORT=%d", GRAPHQL_PORT),       // GRAPHQL_PORT
  fmt.Sprintf("PLAYGROUND_PORT=%d", PLAYGROUND_PORT), // this value is used
)

You can pass query schema:

query := `
  type Query {
    hello: String
  }
`
cmd := exec.Command("node", "index.js", query)

Once playground server will run you will see output like

🚀 GraphQL Express playground server is running on: http://localhost:8081/graphql
