Updated for Hyperledger Burrow v0.18.0 This document has inspired by truffle README.md
Snak is a node.js app which already is under development, aiming to facilitate working with hyperledger Burrow without using Monax.
- Easily install and uninstall hyperledger burrow.
- Built-in smart contract compilation, linking, deployment.
- Having interaction with blockchain(Burrow) directly via linux terminal.
- Automated contract testing with Mocha and Chai(will be added in future).
- Network management for deploying to many public & private networks.
- Interactive console for direct contract communication(will be added in future).
$ npm install -g snak
Install Burrow
(for now only Ubuntu 16.04 amd64 and Darwin are supported)
will copy Burrow necessary files in the '$HOME/burrow'
$ snak install_burrow
This command will install hyperledger burrow on the $/HOME/burrow and by default use the http://localhost:1337/rpc.
You can find a predefined accounts on this directory.
Uninstall Burrow
This command will delete the '$HOME/burrow'
$ snak uninstall_burrow
Run Burrow
$ snak run_burrow
This command at first run the Monax_keys on the default port and then will run the Burrow.
Please be sure that before running Burrow, import the keys which already are located in the burrow installation directory.
$ snak import_keys $HOME/burrow/account_list.json
Send random transaction
$ snak rtx <count>
This command uses the pre-defined acounts to send the random amount transactions between these accounts!
Send transaction
$ snak send <priv_key> <address> <fee>
For a default set of contracts and tests, run the following within an empty project directory:
Initialize project:
$ snak init
From there, you can run snak compile
, snak migrate
and snak test
(will be implemented in future) to compile your contracts, deploy those contracts to the network, and run their associated unit tests.
Compile smart contracts:
$ snak compile
it will compile all the contracts which are already inside the contract folder and makes the Bytecodes and ABIs and put them in the build directory.
Deploy smart contracts:
$ snak migrate [accountname]
[accountname] is optional, if you do not want to use default account you can save your account in a standard account json file in the accounts folder and name it 'account.json'.
Be sure you launch the Burrow using $snak run_burrow
and put all contracts on the contract folder before running these commands.
Call smart contract's functions:
$ snak call <contract_name> <function_name> <parameters_list>
The parameters are pretty clear the only thing you need to care is parameters_list, its formar must be like this: var1,var2,...,varK (comma separated)
List of all commands:
-V, --version output the version number
-h, --help output usage information
Commands:
init|int
Initialize project, makes folders and files which are needed for starting a dapp project.
compile|cmp
Compile all contracts in contracts folder and makes artifacts in the build folder
you need to initialize a project before using this command.
migrate|mgt [accountname]
deploy contract on the Burrow
you need to initialize a project before using this command.
