const config = {
  appName: 'your-app',

  },
  customHttpAgent: new https.Agent({keepAlive: true}), // (OPTIONAL) Define a custom https agent, import https from node to use this constructor. See https://node.readthedocs.io/en/latest/api/https/#https_class_https_agent for more information.
  enableStrictTypeConversion: true // Ensures that all responses returned by the API methods will be type-safe and match the Models explicitly, For Example, the enums will be returned as integer values instead of as Strings as previously were.

Release Notes

Please see the Github releases for in-depth release notes.

Typescript support

As of version 22.11.0, Typescript support is included in the SDK. Models and Enums included in addition to typing for all of the API methods and parameters. The team welcomes any feedback on this feature.

Models and Enums can be imported into Typescript projects as follows:

import { AddressResolutionModel } from 'avatax/lib/models';
import { AddressCategoryId } from 'avatax/lib/enums';

SDK Development

Adding integration test credentials

Running integration tests will hit the deployed lower environment

Test credentials are resolved in the following order:

1. Environment variables

The following environment variables will get loaded as test credentials

SANDBOX_USERNAME="your-username"
SANDBOX_PASSWORD="your-password"

1. Local credentials file

You can also add a local credentials file to the the path "<project_root>/local_creds.json". This file will be gitignored

{
  "username": "your-username",
  "password": "your-password"
}

1. Static (mock) values

The mocked values are used for unit tests via 'nock'.

The test credentials helper can be found here https://github.com/avadev/AvaTax-REST-V2-JS-SDK/blob/master/test/helpers/load_creds.js
