etherlime-2-Etherlime Library API-deployer

deploy(contract, [libraries], [params])

Parameters参数:

• contract - descriptor object for contract to be deployed. More details below被部署合约的描述对象，更多细节在下面
• libraries - key-value object containing all libraries which will be linked to the contract. 链接到合约的包含所有库的键-值对象
• params - the constructor params you’d need to pass on deploy (if there are any) 在部署中你需要传给合约构造函数的参数（如果需要的话）
  

The contract is descriptor object that needs to have at least the following three fields:

合约是至少需要下面三个字段的描述对象

• contractName - the name of the contract 合约名字
  
• abi - the abi interface of the contract 合约abi接口
  
• bytecode - the compiled bytecode 编译的字节码
  

The easiest way to get such descriptor is to compile your solidity files via etherlime compile

最简单的得到描述者的方法是通过etherlime compile编译你的solidity文件

The libraries object should be in the following format:

文件对象应该是如下的格式：

{
    libraryName0: ‘0xAddressOfLibrary0‘,
    libraryName1: ‘0xAddressOfLibrary1‘
}

If the contract to be deployed doesn’t contains any libraries, {}, undefined, null, false or 0 can be passed. For convenience we have made the deploy function to work even without this parameter passed.

如果被部署的合约没有包含任何的库，那么可以传递{}, undefined, null, false 或0给库对象。为了方便，即使没有这些参数被传递我们也可以让部署函数工作起来

Example举例说明：

Linking libraries链接库

const contractUsingQueueAndLinkedList = require(‘...‘);

const libraries = {
    Queue: ‘0x655341AabD39a5ee0939796dF610aD685a984C53,
    LinkedList: ‘0x619acBB5Dafc5aC340B6de4821835aF50adb29c1‘
}

await deployer.deploy(contractUsingQueueAndLinkedList, libraries);

Skipping linking on contract without arguments

跳过库链接并且合约构造函数不需要参数

const contractWithoutLibraries = require(‘...‘);

await deployer.deploy(contractWithoutLibraries);

Skipping linking on contract with arguments

跳过库链接，合约构造函数需要参数

const contractWithoutLibraries = require(‘...‘);

await deployer.deploy(contractWithoutLibraries, false, param1, param2);

estimateGas(contract, [libraries], [params])估计使用的gas

Estimates the gas that this transaction is going to cost you.估计这个交易将要花费的gas

Parameters参数:

• contract - descriptor object for contract to be deployed 部署的合约的描述对象
  
• libraries - key-value object containing all libraries which will be linked to the contract. 链接到合约的包含所有库的键-值对象
  
• params - the constructor params you’d need to pass on deploy (if there are any)在部署中你需要传给合约构造函数的参数（如果需要的话）

The contract is descriptor object is the same as above.

合约是和上面一样的描述对象

Example举例说明

const estimate = await deployer.estimateGas(TestContract, randomParam1, randomParam2);
// returns something like "2470692"
