⚠️ Attention! The IBM Blockchain Platform Extension for VS Code project is no longer active

IBM Blockchain Platform Extension for VS Code

The IBM Blockchain Platform extension helps developers to create, test and debug smart contracts, connect to Hyperledger Fabric environments, and build applications that transact on your blockchain network.

For a step-by-step guide on getting started with the extension's features, access our Beginner Tutorial via our integrated Home page. Alternatively, explore, clone and open the Hyperledger Fabric samples, all without leaving VS Code. For more comprehensive documentation, follow this link

Installation

Please visit the Visual Studio Code Marketplace for installation and more details.

Requirements

The first time you install this extension, it will check your system for the prequisites, and guide you to install any that you are missing.

Windows 10, Linux, or Mac OS are currently the supported operating systems. Each of these operating systems have their own additional requirements.

For the full list of requirements that the extension will check for, please refer to the 'Dependency Installation' section at the end of the README.

Smart Contract Development Lifecycle

Please note that all commands contributed by this extension are accessible via the VS Code Command Palette. The commands outlined below are available from burger menus located on the panel headers, or by right-clicking tree items, in the extension's side bar view.

The expected smart contract development lifecycle follows several broad points, all possible entirely within VS Code using this extension:

  1. Creating and packaging a smart contract
  2. Connecting to an instance of Hyperledger Fabric
  3. Deploying a smart contract
  4. Submitting transactions and generating functional-level smart contract tests

Common tasks and how to complete them

Once you have installed the IBM Blockchain Platform VS Code extension, it is possible to access a large set of tutorials using the >View Tutorial Gallery command.

The tutorial gallery is best place to start once you have installed the extension and will teach you mostly everything that you need to know!

Some information on how to complete other undocumented tasks can be found here.

Useful Commands

The IBM Blockchain Platform extension provides an explorer and commands accessible from the Command Palette, for developing smart contracts quickly:

Dependency Installation

Click to view installation instructions

The following dependencies are required on all operating systems:

VS Code version can be found by running: code --version

The following dependencies are optional:

Node version can be found by running: node --version

npm version can be found by running: npm --version

If installing Node and npm using a manager such as 'nvm' or 'nodenv', you will need to set the default/global version and restart VS Code for the version to be detected by the Prerequisites page.

Go version can be found by running: go version

Java version can be found by running: java -version

Additional requirements for Windows

  • You are using Windows 10 Pro or Enterprise and have the Anniversary Update 1607

1 Org Local Fabric functionality

This extension can use Docker to run a simple pre-configured local Hyperledger Fabric network on your machine. By default this feature is enabled as we highly recommend using it, however you may disable this feature if required.

You will need the following:

Docker version can be found by running: docker --version

Additional requirements for Windows

  • Docker for Windows is configured to use Linux containers (this is the default)
  • You will need to install OpenSSL v1.0.2 OpenSSL binaries
    • Install the normal version, not the version marked as "light"
    • Install the Win64 version into C:\OpenSSL-Win64 on 64-bit systems

For more information see the 1 Org Local Fabric section.

Additional information

To open the Prerequisites page manually, run the View Prerequisites command inside VS Code from the Command Palette.

Please note: the extension doesn't currently work with the VSCode Remote Development feature, we plan to make this work in the future, follow progress here.

Contact Us

If you have find any problems or want to make suggestions for future features please create issues and suggestions on Github.

Just so you know

The extension uses telemetry reporting to track usage data and help improve future extension versions. Disabling VS Code telemetry reporting also disables the extension's telemetry reporting. For instructions on how to disable telemetry reporting, please visit the Visual Studio Code FAQ
