srp-data-api

npm package for SRP company for data extraction

• This package contains two methods of data extraction

1. getServiceAccounts - It gives the response in the form of list of service-accounts related to given user-account
2. getMonthlyUtilityData - It gives the response in the form of list of monthly-utility-data for given service-account

Installation

npm i srp-data-api --save

How to use?

import { SRPUtilityDataService } from 'srp-data-api';
const srpUtilityDataService = new SRPUtilityDataService();

const payload: GetDataPayload = {
    password: string;
    username: string;
  };

const res = await srpUtilityDataService.getServiceAccounts(payload)

After data extraction, we will get response as -

res: UtilityUserAccountResponse = {
      id: string
      name: string
      serviceAccounts[]: [{id:string, address:Address}]
    };

const res = await srpUtilityDataService.getMonthlyUtilityData(payload)

After data extraction, we will get response as -

res: MonthlyUtilityData[] = {
      _id: string
      amountInCents: number
      energyConsumptionInWatts: number
      month: string
      serviceAccountId: string
      year: number
  };

Methods

    getServiceAccounts: (
      payload: GetDataPayload,
    ) => Promise<UtilityUserAccountResponse>;

    getMonthlyUtilityData: (
      payload: GetDataPayload,
    ) => Promise<MonthlyUtilityData[]>;

    setProxy:(proxy: string[]) => Promise<void>

Options

GetDataPayload = {
    password: string;
    username: string;
  };

WHERE,
password: password of the user-account
username: username of the user-account

proxy:string[]

WHERE,
proxy: VGS proxy we set

Responses

    };

WHERE,
id: user-account id
name: Name of the user

      energyConsumptionInWatts: number
      month: string
      serviceAccountId: string
      year: number
  };

Error Handling

• If we pass incorrect credentials for getting utility-data, then...

import { SRPUtilityDataService } from 'srp-data-api';
const srpUtilityDataService = new SRPUtilityDataService();

const payload: GetDataPayload = {
    password: incorrect-username;
    username: incorrect-password;
  };

const res = await srpUtilityDataService.getServiceAccounts(payload)

• The Promise gets rejected with AuthenticationError with message - The user name or password is incorrect.

• If we pass correct credentials for getting utility-data, but data extraction failed and service cannot extract data, then...

import { SRPUtilityDataService } from 'srp-data-api';
const srpUtilityDataService = new SRPUtilityDataService();

const payload: GetDataPayload = {
    password: correct-username;
    username: correct-password;
  };

const res = await srpUtilityDataService.getMonthlyUtilityData(payload)

• The Promise gets rejected with DataExtractionError with message - Failed to extract data
