A plugin for retrieving configuration objects to be used to create Dai.js Maker instances.

Dai Config Plugin

Development

This plugin fetches configuration data from a testchain backend, and creates a config object to be provided to the Maker SDK so it can be used with a testchain. Add it to the end of the plugins array to ensure the options override the default config.

see Dai.js for more details

Example using the Maker SDK

import Maker from '@makerdao/dai';
import configPlugin from '@makerdao/dai-plugin-config';

const config = {
    plugins: [
        [configPlugin, { testchainId: '123abc', backendEnv: 'dev' }]
        ],
    log: false
  };

await Maker.create('http', config);

Details

testchainId: Must be a running testchain ID on the selected backend environment.

backendEnv: (optional) defaults to the 'prod' URL, which is http://18.185.172.121:4000/chain/. Options are prod, dev, or any user-specified URL.

In the beforeCreate block, the plugin will fetch testchain data from the URL. This includes the testchain RPC, all the deployed contracts, and required tokens. It will create a config object that looks like this:

config = {
        url: rpc_url,
        provider: {
          type: 'HTTP',
          network: chainConfig.type
        },
        smartContract: { addContracts },
        token: { erc20 }
      };

Code Style

We run Prettier on-commit, which means you can write code in whatever style you want and it will be automatically formatted according to the common style when you run git commit.
