3 Using the Blockchain App Builder Extension for Visual Studio Code
The Blockchain App Builder extension for Visual Studio Code helps you build and scaffold a fully-functional chaincode project from a specification file.
After the project is built, you can run and test it on a local Hyperledger Fabric network or your provisioned Oracle Blockchain Platform network. You can then run SQL rich queries, debug the chaincode, or write and run unit tests using the generated code.
Table 3-1 Workflow When Using the Visual Studio Code Extension
| Task | Description | More Information |
|---|---|---|
| Install and configure | Download the Blockchain App Builder Visual Studio Code extension from your Oracle Blockchain Platform console and install it and any prerequisite software. | |
| Create the chaincode project | Create a specification file for the chaincode project. | |
| Generate the chaincode | Edit the specification file to define the assets and chaincodes to generate, and then generate your chaincode from the specification file. |

contents of the specification file and the generated chaincode
project:
|
| Deploy the chaincode |
Deploy the chaincode project locally to the included preconfigured Hyperledger Fabric network or remotely to Oracle Blockchain Platform Cloud or Enterprise Edition. You can also package the chaincode project for manual deployment to Oracle Blockchain Platform. |
|
| Test the chaincode |
After your chaincode is running on a network, you can test any of the generated methods. Additionally, If you chose to create the |
|
| Debug the chaincode | You can do line-by-line debugging in Visual Studio Code. | |
| Synchronize your updates | When you update your specification file, you can synchronize the changes with the generated chaincode files. | |
| Running unit tests | A basic unit test case setup is included in the project. Additional tests can be added and run. |
