IAUX User Service

This is a Typescript library to interact with the Internet Archive's User Service.

Usage

import { UserService } from '@internetarchive/user-service';

// instantiate a UserService object
const userService = new UserService();

// get the result
const result = await userService.getLoggedInUser();

// if the user is logged in, the User object will be in `result.success`
const user = result.success;
if (user) {
  console.debug(
    'User:', user.username, user.itemname, user.screenanme, user.privs
  )
  return;
}

// if the user is not logged in or you an error occurred,
// you'll get a `result.error` and can inspect `result.error.type`:
switch (result.error?.type) {
  case UserServiceErrorType.userNotLoggedIn:
    console.info('User not logged in');
    break;
  case UserServiceErrorType.networkError:
    console.error('There was a network error fetching the user');
    break;
  case UserServiceErrorType.decodingError:
    console.error('There was an error decoding the user service response');
    break;
  default:
    console.error('An unknown error occurred fetching the user');
}

Advanced Usage

Caching

You can pass in a cache handler that implements UserServiceCacheInterface and the results will be cached:

import { LocalCache } from '@internetarchive/local-cache';

const cache = new LocalCache();
const service = new UserService({
  cache,
  cacheTTL: 15 * 60 // seconds, optional
})
const result = await service.getLoggedInUser();
// subsequent calls will be cached

Tooling configs

For most of the tools, the configuration is in the package.json to reduce the amount of files in your project.

If you customize the configuration a lot, you can consider moving them to individual files.
