Returns a boolean and the balance of the dashboard to avoid an extra call to getBalance.
Note that if the switch did not succeed, the balance data would not match the card number requested. You must check the success field.
Raises NoCardError if no card associated with the account.
Raises NotLoggedIn if not logged-in.

Returns activities for a given month. month parameter is zero-indexed, acceptable values are 0-11.
pageSize is an optional parameter with a default value of '200'
Example: Get activity for December 2017:
await getActivityByMonth(2017, 11)
// => [
// {
// agency: 'Toronto Transit Commission',
// amount: '$3.00',
// balance: '$75.00',

pageSize is an optional parameter with a default value of '200'
Example: Get activity from Feb 15 2017 to Jan 9 2018
await getActivityByDateRange('2017-02-15', '2018-01-09')
// => [
// {
// agency: 'Toronto Transit Commission',

// type: 'Fare Payment',
// },
// ]You may want to build a wrapper using a custom axios instance if you want to use though-cookie in a NodeJS environment.
Example:
const axios = require('axios');
const axiosCookieJarSupport = require('axios-cookiejar-support').default;
const { getAPIWrapperWithAxiosInstance } = require('presto-card-js');
const axiosInstance = axiosCookieJarSupport(axios);
axiosInstance.defaults.jar = true;
const prestoCard = getAPIWrapperWithAxiosInstance(axiosInstance);
(async () => {
const loginResponse = await prestoCard.login(username, password);
[...]
})();Since PRESTO does not provide a public API, the library executes HTTP requests to login and it parses the dashboard HTML in order to get the card info.
