⚠️ ⚠️ ⚠️

As of the 29th August 2019, the Hyperledger Composer project is in deprecated status. None of the maintainers are actively developing new features. None of the maintainers are actively providing support via GitHub issues. However, if you wish to submit code changes via pull requests, these will be merged.

It is highly recommended that you use Hyperledger Fabric v1.4+ instead, which features significant improvements to the developer experience, including a new programming model.

More information available here: What's new in Hyperledger Fabric v1.4

Validate Composer model files that define the structure of your business network in terms of Assets, Participants and Transactions.

The extension parses Composer model (.cto) files and reports any validation errors. It is currently in beta; please raise any problems you find as an issue.

Generate the installable VSIX file:

git clone https://github.com/hyperledger/composer-vscode-plugin.git
cd composer-vscode-plugin/server
npm install
npm run compile:server
cd ../client
npm install
npm run package:vsix

1. Launch VSCode
2. View > Extensions
3. Press the ... and select "Install from VSIX"
4. Browse to the VSIX file
5. Install and restart VSCode
6. Open a .cto file

Developers no longer need a manual build, once you have pulled a request from your private Github repository. The build will be automatically performed by Travis. A successful build will create an installable VSIX file on the build machine. The public release version number is defined in the Client package.json file.
