Chain Deployment

• configure the deployed project/package with the minimal configuration looking like here.
• config is convict-based configuration, so you can override values accordingly.
• create a deploy script similar to this, to be executed via:

  $> NODE_ENV=<env> yarn deploy

• the resulting deployment artifacts will saved in <deploymentDir>/chain/<env>/.evms.json

Generating javascript source for contracts interaction

to support interaction with deployed contract, you can generate a corresponding source files like so:

• create a generate-contract-exports script such as this, to be executed via:

    $> node scripts/generate-contract-exports

• the resulting javascript files will reside within <process.env.PWD>/src/contracts/
