Hyperledger Fabric Client SDK for Go

Release License GoDoc

Build Status codecov Go Report Card

This SDK enables Go developers to build solutions that interact with Hyperledger Fabric.

Getting started

Obtain the client SDK packages for Fabric and Fabric CA.

go get github.com/littlegirlpppp/fabric-sdk-go-gm

You're good to go, happy coding! Check out the examples for usage demonstrations.

Documentation

SDK documentation can be viewed at GoDoc.

The packages intended for end developer usage are within the pkg/client folder along with the main SDK package (pkg/fabsdk).

If you wish to use the Fabric 'Gateway' programming model, then the API is in the pkg/gateway folder.

Examples
  • E2E Test: Basic example that uses SDK to query and execute transaction
  • Ledger Query Test: Basic example that uses SDK to query a channel's underlying ledger
  • Multi Org Test: An example that has multiple organisations involved in transaction
  • Dynamic Endorser Selection: An example that uses dynamic endorser selection (based on chaincode policy)
  • E2E PKCS11 Test: E2E Test using a PKCS11 crypto suite and configuration
  • CLI: An example CLI for Fabric built with the Go SDK.
  • More examples needed!
Community
  • Discussion is happening in Rocket Chat.
  • Issue tracking is handled in Jira.

Client SDK

Current Compatibility

The SDK's integration tests run against three tagged Fabric versions:

  • prev (currently v1.4.7)
  • stable (currently v2.2.0)
  • prerelease (currently disabled)

Additionally for development purposes integration tests also run against the devstable Fabric version as needed.

Retired versions

When the 'prev' code level is updated, the last tested fabric-sdk-go commit or tag is listed below.

  • fabric v1.3: ac70276
  • fabric v1.2: 5e291d3
  • fabric v1.1: f7ae259
  • fabric v1.0: 5ac5226
Running the test suite

Obtain the client SDK packages for Fabric and Fabric CA.

git clone https://github.com/littlegirlpppp/fabric-sdk-go-gm.git
# In the Fabric SDK Go directory
cd fabric-sdk-go/

# Optional - Automatically install Go tools used by test suite
# make depend

# Running test suite
make

# Clean test suite run artifacts
make clean
Go Tags

The following Go tags can be supplied to enable additional functionality:

  • experimental: includes support for experimental features.

Contributing to the Go SDK

If you want to contribute to the Go SDK, please run the test suite and submit patches for review. For general guidelines, please refer to the Fabric project's contribution page.

You need:

  • Go 1.14
  • Make
  • Docker
  • Docker Compose
  • Git
  • gobin (GO111MODULE=off go get -u github.com/myitcv/gobin)
  • libtool

Notes:

Running a portion of the test suite
# In the Fabric SDK Go directory
cd fabric-sdk-go/

# Optional - Automatically install Go tools used by test suite
# make depend

# Optional - Running only code checks (linters, license, spelling, etc)
# make checks

# Running all unit tests and checks
make unit-test

# Running all integration tests
make integration-test
Running package unit tests manually
# In a package directory
go test
Running integration tests manually

You need:

  • A working fabric and fabric-ca set up. It is recommended that you use the docker-compose file provided in test/fixtures/dockerenv. It is also recommended that you use the default .env settings provided in test/fixtures/dockerenv. See steps below.
  • Customized settings in the test/fixtures/config/config_test.yaml in case your Hyperledger Fabric network is not running on localhost or is using different ports.
Testing with Fabric Images at Docker Hub

The test suite defaults to the latest compatible tag of fabric images at Docker Hub. The following commands starts Fabric:

# In the Fabric SDK Go directory
cd fabric-sdk-go

# Start fabric (stable tag)
make dockerenv-stable-up

# Or more generally, start fabric at a different code level (prev, stable, prerelease, devstable)
# make dockerenv-[CODELEVEL]-up
Running Integration Tests

Fabric should now be running. In a different shell, run integration tests

# In the Fabric SDK Go directory
cd fabric-sdk-go

# Use script to setup parameters for integration tests and execute them
# Previously we use to have hostnames like Fabric CA server, orderer and peer pointed to localhost
# Now since we removed this now, We will be using a different configuration
make integration-tests-local

# Or more generally, run integration tests at a different code level (prev, stable, prerelease, devstable)
# and fixture target version
# FABRIC_CODELEVEL_VER=[VER] FABRIC_CODELEVEL_TAG=[CODELEVEL] make integration-tests-local
# Previously we use to have hostnames like Fabric CA server, orderer and peer pointed to localhost
# Now since we removed this now, We will be using a different config file config_test_local.yaml
# which has the Fabric CA server, orderer and peers pointed to localhost
# It is also possible to run integration tests using go test directly. For example:
#cd fabric-sdk-go/test/integration/
#go test -args testLocal=true

#cd fabric-sdk-go/test/integration/orgs
#go test -args testLocal=true 

# You should review test/scripts/integration.sh for options and details.
# Note: you should generally prefer the scripted version to setup parameters for you.
Testing with Local Build of Fabric (Advanced)

Alternatively you can use a local build of Fabric using the following commands:

# Start fabric (devstable codelevel with latest docker tags)
make dockerenv-latest-up

Overview

Package fabricsdk enables Go developers to build solutions that interact with Hyperledger Fabric.

Packages for end developer usage

pkg/fabsdk: The main package of the Fabric SDK. This package enables creation of contexts based on configuration. These contexts are used by the client packages listed below. Reference: https://godoc.org/github.com/littlegirlpppp/fabric-sdk-go-gm/pkg/fabsdk

pkg/client/channel: Provides channel transaction capabilities. Reference: https://godoc.org/github.com/littlegirlpppp/fabric-sdk-go-gm/pkg/client/channel

pkg/client/event: Provides channel event capabilities. Reference: https://godoc.org/github.com/littlegirlpppp/fabric-sdk-go-gm/pkg/client/event

pkg/client/ledger: Enables queries to a channel's underlying ledger. Reference: https://godoc.org/github.com/littlegirlpppp/fabric-sdk-go-gm/pkg/client/ledger

pkg/client/resmgmt: Provides resource management capabilities such as installing chaincode. Reference: https://godoc.org/github.com/littlegirlpppp/fabric-sdk-go-gm/pkg/client/resmgmt

pkg/client/msp: Enables identity management capability. Reference: https://godoc.org/github.com/littlegirlpppp/fabric-sdk-go-gm/pkg/client/msp

Basic workflow

  1. Instantiate a fabsdk instance using a configuration. Note: fabsdk maintains caches so you should minimize instances of fabsdk itself.
  2. Create a context based on a user and organization, using your fabsdk instance. Note: A channel context additionally requires the channel ID.
  3. Create a client instance using its New func, passing the context. Note: you create a new client instance for each context you need.
  4. Use the funcs provided by each client to create your solution!
  5. Call fabsdk.Close() to release resources and caches.

Support for Hyperledger Fabric programming model

In order to support the 'Gateway' programming model, the following package is provided:

pkg/gateway: Enables Go developers to build client applications using the Hyperledger Fabric programming model as described in the 'Developing Applications' chapter of the Fabric documentation. Reference: https://godoc.org/github.com/littlegirlpppp/fabric-sdk-go-gm/pkg/gateway
