## HLF go chaincode template

### Start tunnel

```bash

ngrok tcp 9999

```

### Install, approve and commit chaincode

```bash

CHAINCODE_NAME=template_go

API_URL="http://localhost:8080/graphql"

SIGNATURE_POLICY="OR('Org1MSP.member', 'Org2MSP.member')"

CHAINCODE_ADDRESS_TUNNEL="4.tcp.eu.ngrok.io:13438" # the forwarding URL you get from opening an ngrok tunnel

hlf-cc-dev start --localChaincode="localhost:9999" \

  --chaincodeAddress="${CHAINCODE_ADDRESS_TUNNEL}" \

  --chaincode="${CHAINCODE_NAME}" \

  --signaturePolicy="${SIGNATURE_POLICY}" \

  --env-file="${PWD}/.env" \

  --apiUrl="${API_URL}"

```

### Start chaincode

```bash

source .env && go run ./main.go

```

### Test chaincode

You can go to the playground(instead of /graphql, use /playground) and use the following mutation and query to test the chaincode:

```graphql

mutation invoke {

  invokeChaincode(input:{

    chaincodeName:"template_go"

    function: "InitLedger"

    args: []

    transientMap: []

  }){

    response

    transactionID

    chaincodeStatus

  }

}

mutation query {

  queryChaincode(input:{

    chaincodeName:"template_go"

    function: "GetAllAssets"

    args: []

    transientMap: []

  }){

    response

    chaincodeStatus

  }

}

```
