JavaScript library for the ZeppelinOS smart contract platform.
ZeppelinOS is a platform to develop, deploy and operate smart contract projects on Ethereum and every other EVM and eWASM-powered blockchain.
This is the repository for the ZeppelinOS JavaScript library. It is mainly used
by the
zos command-line interface,
which is the recommended way to use ZeppelinOS; but this library can also be
used directly to operate ZeppelinOS projects when a programmatic interface is
preferred or more flexibility and lower-level access is required.
First, install Node.js and npm. Then, install the ZeppelinOS JavaScript Library running:
npm install zos-lib
Suppose there is a contract called MyContract in the file
contracts/MyContract.sol, already compiled to
build/contracts/MyContract.json, and that there is a development blockchain
network running locally in port 9545.
Open a Node.js console:
node
> const { ZWeb3, Contracts, SimpleProject } = require('zos-lib')
> // Initialize a web3 provider.
> ZWeb3.initialize("http://localhost:9545")
> // Load the contract.
> const MyContract = Contracts.getFromLocal('MyContract')
> // Instantiate a project.
> myProject = new SimpleProject('MyProject', { from: await ZWeb3.defaultAccount() })
> // Create a proxy for the contract.
> myProject.createProxy(MyContract).then(proxy => myProxy = proxy)
> // Make a change on the contract, and compile it.
> const MyContractUpgraded = Contracts.getFromLocal('MyContract')
> myProject.upgradeProxy(proxy, MyContractUpgraded)
