Distributed identity

use api

import {identity} from '@bpfaas/common'

// a unique id.

if (!identity.isValidId(id)) {
}

// id length.
identity.idLength == 32

use decorator

import {Identity} from '@bpfaas/common'

class Demo {
  @Identity
  id: string;
}

// a unique id.
new Demo().id

ErrorCode

import {errorCode, isErrorCode, getErrorCodeMsg} from '@bpfaas/common';

// get the errCode
errorCode.OK                // 200
errorCode.OK_SYNC           // 202

errorCode.OPERATOR_LIMITED  // 445
errorCode.SERVICE_ERROR     // 500
errorCode.SERVICE_UNAVAILABLE  // 504

isErrorCode(200) == true
getErrorCodeMsg(errorCode.OPERATOR_EXPIRED) // 'OPERATOR_EXPIRED'

Msg

Network message package.

import {Msg, errorCode} from '@bpfaas/common';

let msg:Msg = {
  err_code: errorCode.OK,
  err_msg: 'error message',
  err_subcode: 'bll error code',
  data: {
    ...
  }
}

Auth
