Implement IDBFactory and IDBRequest's onsuccess、onerror method

interface IDBFactoryOptions {
    sign(target: Uint8Array): Promise<[Uint8Array, Uint8Array]>;
    nonce(): number;
}
interface IDBFactory {
    /**
     * Compares two values as keys. Returns -1 if key1 precedes key2, 1 if key2 precedes key1, and 0 if the keys are equal.
     *
     * Throws a "DataError" DOMException if either input is not a valid key.
     */
    // cmp(first: any, second: any): number;
    databases(): Promise<IDBDatabaseInfo[]>;
    /** Attempts to delete the named database. If the database already exists and there are open connections that don't close in response to a versionchange event, the request will be blocked until all they close. If the request is successful request's result will be null. */
    deleteDatabase(name: string): IDBOpenDBRequest;
    /** Attempts to open a connection to the named database with the current version, or 1 if it does not already exist. If the request is successful request's result will be the connection. */
    open(name: string, options: IDBFactoryOptions,  version?: number): IDBOpenDBRequest;
}

DB3 interface dependencies

• create database
• get database by name
• get all database
• delete database

Motivations

• Would you like to implement this feature? [y/n]

Interface implementation

• IDBFactory Provides access to a database. 01.09
• IDBOpenDBRequest Represents a request to open a database. 01.13
• IDBDatabase Represents a connection to a database. It's the only way to get a transaction on the database. 01.16
• IDBTransaction Represents a transaction. You create a transaction on a database, specify the scope, and determine the kind of access (read only or readwrite) that you want. 01.20
• IDBRequest Generic interface that handles database requests and provides access to results. 01.31
• IDBObjectStore Represents an object store that allows access to a set of data in an IndexedDB database, looked up via primary key. 02.06
• IDBIndex Also allows access to a subset of data in an IndexedDB database, but uses an index to retrieve the record(s) rather than the primary key 02.08
• IDBKeyRange Defines a key range that can be used to retrieve data from a database in a certain range. 02.13

dbpunk-labs/db3#233 aim at removing session_status from db3 proto.

We need to update the related API and proto usage in db3.js

Hi,

I'm wondering if there is an example that uses a MetaMask wallet?

How to produce the error

yarn dev and visit the browser

• Excerpt the firestore and db3 functional overlapping interfaces.
• Design the db3 interfaces.
• Implement the db3 interfaces
  • Initialize the app connection db3 node
  • manage db3 data (add data, get data)
  • index types

Right now the only way to use DB3 server side is through a wallet that reads a mnemonic. Mnemonics give access to all of the user's accounts which is not very good for security. In ethers for example, to initiate a wallet you only need a private key.

So I suggest having it as an option for a provider. It could be used somehow like this:

const DB3 = DB3EOAWallet(process.env.PK)
