@exodus/multi-account-redux

下列形状的状态管理选择器和公用设备:

{
  [yourStateSliceName]: {
    [walletAccount]: {
      error: null,
      loaded: true,
      data: {
        [assetName]: {}, // TxSet/UtxoCollection/etc.
      },
    },
  }
}

安装

pnpm add @exodus/multi-account-redux

使用量

import { TxSet } from '@exodus/models'
import { createReduxModuleHelper } from '@exodus/multi-account-redux'

const helper = createReduxModuleHelper({
  slice: 'someAssetSourceRelatedData',
  createInitialPerAssetData: () => TxSet.EMPTY,
})

const myReduxModule = {
  id: 'someAssetSourceRelatedData',
  initialState: helper.createInitialState(),
  eventReducers: {
    someAssetSourceRelatedData: (state, data) => {
      // check source code for other utils for merging/resetting state
      return helper.setAccounts(state, data)
    },
  },
  selectorDefinitions: [...helper.selectorDefinitions, ...customSelectorDefinitions],
}

类型脚本投影推论

让帮助者从初始化器中推断出每个资产的数据. 投影参数,选择器名称, 然后在不标注每个选择者的情况下推断返回类型:

const helper = createReduxModuleHelper({
  slice: 'balances',
  createInitialPerAssetData: () => ({ balance: 0 }),
  assetSourceDataSelectors: [
    { name: 'balance', selector: (data) => data?.balance ?? 0 },
    { name: 'label', selector: (data) => String(data?.balance ?? 0) },
  ],
})

收到预测 null 或者说 undefined 资产未知时,或无资产时 createInitialPerAssetData 资产没有存储数据。 每个案子都处理好 选择器.

在提供明确数据或资产类型时,使用两个调用,因此预测类型仍然可以 推断:

type Balance = { balance: number }
type Asset = { name: string; initialBalance: number }

const helper = createReduxModuleHelper<Balance, Asset>()({
  slice: 'balances',
  createInitialPerAssetData: ({ asset }) => ({ balance: asset.initialBalance }),
  assetSourceDataSelectors: [{ name: 'balance', selector: (data) => data?.balance ?? 0 }],
})

原画 createReduxModuleHelper<Balance>({...}) 表格仍然支持。 有了预测, 它保存数据类型,但将投影名称扩大到字符串和结果 unknown。 。 。 . 使用双调形式精确投影类型.
