# Hyperledger Fabric GraphQL Boilerplate

This is a boilerplate to start using hyperledger fabric blockchain with GraphQL

- based on: [fabric-boilerplate](https://github.com/IBM-Blockchain/fabric-boilerplate)

- based on GraphQL boilerplate code: [graphql-dataloader-boilerplate](https://github.com/entria/graphql-dataloader-boilerplate)

- [Create-GraphQL](https://github.com/lucasbento/create-graphql) was used to generate GraphQL boilerplate

## How to build Go chaincode locally

### Install go

```

brew install go

mkdir ~/.go

```

### Configure GOPATH

add this to .bashrc

```

export GOPATH="${HOME}/.go"

export GOROOT="$(brew --prefix golang)/libexec"

```

```

yarn go:install

```

then

```

yarn go:build

```

# Run locally with docker-compose

Clear content of deploy/local before creating new containers

```

yarn clear

```

```

docker-compose up

```

## Test if it is running ok

go to `http://localhost:7050/chain`

## Go to Hyperledger Explorer

go to `http://localhost:9090`

## How to test chaincode

```

yarn run go:test

```

## How to interact with chain

```

yarn repl

```

Query data for an entity (**a** and **b** are the valid entities for now)

```

bl > queryEntity('a')

```

Transfer **coins** from an entity to another

```

bl > transfer('a', 'b', 10)

```

### How to deploy a new chaincode using GraphQL

```graphql

mutation deployChain {

 Deploy(input: {

  fcn:"init"

  args: ["a", "100", "b", "200"]

  clientMutationId:"1"

	}) {

  	results

	}

}

```
