IndexedDb Schema

Each top level object is its own key-value store database.

  Accounts {
    [accountId: string]: Account
  }
  AccountsMetadata {
    accountIds: strings[] // this array sets the order of the accounts
    activeAccountId: string // the default account to use with all hooks and actions
    accountNamesToAccountIds: {[accountName: string]: accountId}
  }
  AccountsComments (each database named accountComments-[accountId]) {
    [commentIndex: number]: AccountComment // store in array because cid is still unknown
  }
  AccountsCommentsReplies (each database named accountCommentsReplies-[accountId]) {
    [commentCid: string]: AccountCommentReply // keep replies to own account comments in a separate last recently used database because they should be cached for a different amount of time than regular comments and account comments
  }
  AccountsVotes (each database named accountVotes-[accountId]) {
    [commentCid: string]: AccountVote
  }
  Communities {
    [communityAddress: string]: Community // last recently used database, delete oldest data
  }
  Comments {
    [commentCid: string]: Comment // last recently used database, delete oldest data, different from AccountsComments that never expire
  }
  CommunityPages {
    [pageCid: string]: CommunityPage // last recently used database, delete oldest data
  }
