Motivation & Spec

Fields

Possible fields to exist in a did-agent storage record

• authorizeId: Primary key
• ownerDid: Owner DID
• agentDid: Agent DID
• appDid: Application DID
• appPk: Application public key
• appName: Application name
• appDescription: Application description
• appIcon: Application logo/icon
• certificateContent: Application authorize content

APIs

Basic APIs that a did-agent storage should support:

• create(authorizeId, payload): 创建记录
• update(authorizeId, updates): 更新记录
• read(authorizeId)：按 authorizeId 查询
• delete(authorizeId)：删除记录
• listByApp(appDid): 按应用查询
• listByOwner(ownerDid): 按所有者查询

Install

npm install @arcblock/did-agent-storage
// or
yarn add @arcblock/did-agent-storage

Usage

const StorageInterface = require('@arcblock/did-agent-storage');
let storage = {};
module.exports = class MemoryAgentStorage extends StorageInterface {
  read(authorizeId) {
    return storage[authorizeId];
  }

  create(authorizeId, payload = {}) {
    storage[authorizeId] = Object.assign({ authorizeId }, payload);
    return this.read(authorizeId);
  }

  update(authorizeId, updates) {
    delete updates.authorizeId;
    storage[authorizeId] = Object.assign(storage[authorizeId], updates);
    return storage[authorizeId];
  }

  delete(authorizeId) {
    delete storage[authorizeId];
  }

  listByOwner(ownerDid) {
    Object.keys(storage)
      .filter(x => storage[x].ownerDid === ownerDid)
      .map(x => storage[x]);
  }

  listByApp(appDid) {
    Object.keys(storage)
      .filter(x => storage[x].appDid === appDid)
      .map(x => storage[x]);
  }

  clear() {
    storage = {};
  }
};
