OrderBook 蓝图

安装

npm install aoffp
# or
yarn add aoffp

获取 FFP Settlement Process ID

import { getSettleProcessId } from 'aoffp'

const settleProcessId = getSettleProcessId()
console.log('settleProcessId', settleProcessId)

创建 OrderBook 实例

如果没有创建 OrderBook Agent Process, 需要先创建，创建操作如下：

import { createOrderbookProcess } from 'aoffp'
import { createDataItemSigner } from '@permaweb/aoconnect'

const address = 'your-arweave-address'
const signer = createDataItemSigner(arJWK)
const settleProcessId = getSettleProcessId()
const orderbookAgent = await createOrderbookProcess(signer)
const orderbookProcessId = orderbookAgent.agentId
console.log('orderbookProcessId', orderbookProcessId)

使用 agent-process-id new agent 实例。

import { Orderbook } from 'aoffp'
import { createDataItemSigner } from '@permaweb/aoconnect'

const signer = createDataItemSigner(arJWK)
const orderbookProcessId = 'your-orderbook-process-id'
const settleProcessId = getSettleProcessId()
const orderbook = new Orderbook(signer, orderbookProcessId, settleProcessId)

Agent 操作

充值资金

const depositMessageId = await orderbook.deposit(tokenProcessId, quantity)
console.log('depositMessageId', depositMessageId)

提现资金

const withdrawMessageId = await orderbook.withdraw(tokenProcessId, quantity)
console.log('withdrawMessageId', withdrawMessageId)

获取 FFP 中所有订单

const allOrders = await orderbook.getOrders(tokenIn, tokenOut, status, desc, page, pageSize)
console.log('allOrders', allOrders)

挂单

const order = await orderbook.makeOrder(tokenInProcessId, tokenOutProcessId, quantityIn, quantityOut)
console.log('order', order)

取消挂单

const cancelOrderMessageId = await orderbook.cancelOrder(noteId)
console.log('cancelOrderMessageId', cancelOrderMessageId)

// result
const cancelOrderResult = await getProcessResult(cancelOrderMessageId, orderbookProcessId)
console.log('cancelOrderResult', JSON.stringify(cancelOrderResult, null, 2))

吃单

const takeOrderMessageId = await orderbook.takeOrder([noteId1, noteId2, ...])
console.log('takeOrderMessageId', takeOrderMessageId)

// result
const takeOrderResult = await getProcessResult(takeOrderMessageId, orderbookProcessId)
console.log('takeOrderResult', JSON.stringify(takeOrderResult, null, 2))
