An interactive shell and command-line interface for dai.js
$ npm install -g @bryanwb/dai-shell$ dai COMMANDrunning command...$ dai (-v|--version|version)@bryanwb/dai-shell/0.0.6 linux-x64 node-v10.15.0$ dai --help [COMMAND]USAGE$ dai COMMAND...
Next, you will want to configure dai-shell with an account. Run the
dai init command and
a helpful wizard will walk you through adding your credentials. Note that dai-cli has the
option to store the name of an environment variable to source your private key from. When you tell
dai-cli to use an environment variable it only saves the name of that variable to disk and not your actual private key.
dai init will also ask you for you infura API key. This value is written to disk.
Subsequent configuration changes can be made with the
dai config subcommand. Of special interest is the ability to add multiple accounts with the
dai config add subcommand and switch the default account with the
dai config switch [accountName] subcommand.
Up and Running
dai shell to start a shell connected to a chain. Note that this is a customized node.js REPL w/ special pre-populated variables and support for the
await keyword. All pre-populated variables are accessible from the
- maker: instance of the Maker object connected to the chain specified during
dai config addand with the current private key or mnemonic.
- Maker: The big daddy Maker object
- wallet: instance of wallet object created from the mnemonic/private key you specified and connected to a network
- eth: a connection to Ethereum blockchain.
- utils: utility functions from ethers
Here is an example REPL session:
$ dai replConnecting to kovan - [REDACTED]dai> var cdp = await ctx.maker.openCdp()dai> var result = await cdp.lockEth(0.1, ctx.Maker.ETH)dai> result.receipt.blockNumberdai> result.receipt.transactionHash'0x49195e1dec124de3f3e98af40d499e33d14e73ddde5d56959ceb8981d7ae902a'dai> cdp = await ctx.maker.getCdp(cdp.id)dai> var v = await cdp.getCollateralValue()dai> v.toString()'0.10 ETH'dai> result = await cdp.drawDai(5, ctx.Maker.DAI)dai> var r = await cdp.getCollateralizationRatio()dai> r3.0606
