UW Graduate Applicant Web Service

This package implements the v4 Graduate Applicant Webservice API for Node.js.

Note: node-gaws version 7 supports GAWS api V4. Use node-gaws 6.x for GAWS api V3.

USE

Installation

Install from the NPM package repository.

npm i node-gaws

Basic Use

Import the module and initialize it.

import { Gaws } from 'node-gaws';

const gaws = new Gaws({
  organizationName: 'My Organization Name',
  baseUrl: 'https://testweb.grad.uw.edu/services/applicants/v4/api/',
  auth: {
    cert: 'your certificate data',
    key: 'your key data'
  },
  logLevel: config.logLevel,
});

const gawsApiResponse = await gaws.programs.getAuthorized();

console.log(gawsApiResponse.data);

Certificate Helpers

Usually you do not want to put certificates and other secrets in your code. You can implement your own certificate data retrieval and supply it directly to Gaws. This GAWS API package provides two helper certificate fetchers for retrieving certificate information: file and AWS S3. These helpers are accessed via the certificate fetcher manager.

You can create your own cert fetchers and add them dynamically to the certificate fetcher manager. See the certFetcher tests for examples how to add custom fetchers.

The certificate manager returns a certificate fetcher of the type you specify. Once you have the cert fetcher, you can call readCertificate() to get the certificate data in an object that you can pass directly to the auth option.

File Certificate Fetcher

The file certificate fetcher retrieves the certificate information from the local file system. You pass the path to the certificate and key to the fetcher.

import { Gaws, CertFetcherManager} from 'node-gaws';

const config = {
  organizationName: 'FosterIT-GAWS',
  baseUrl: 'https://testweb.grad.uw.edu/services/applicants/v3/api/',
  logLevel: 'debug',
  certFiles: {
    certPath: 'path to certificate file',
    keyPath: 'path to key file',
  },
};

const certFetcherManager = new CertFetcherManager();

const fetcher = certFetcherManager.getFetcher('file');

const certData = await fetcher.readCertificate(config.certFiles);

const gaws = new Gaws({
  organizationName: config.organizationName,
  baseUrl: config.baseUrl,
  auth: certData,
  logLevel: config.logLevel,
});

const gawsApiResponse = await gaws.programs.getAuthorized();

console.log(gawsApiResponse.data);

S3 Certificate Fetcher

The s3 certificate fetcher retrieves the certificate information from an Amazon AWS S3 object store. You pass the bucket and key for the certificate and key to the fetcher.

import { Gaws, CertFetcherManager} from 'node-gaws';

const config = {
  organizationName: 'FosterIT-GAWS',
  baseUrl: 'https://testweb.grad.uw.edu/services/applicants/v3/api/',
  logLevel: 'debug',
  certFiles: {
    certBucket: 'cert bucket name',
    certKey: 'cert S3 key name',
    keyBucket: 'key bucket name',
    keyKey: 'key S3 key name',
  },
};

const certFetcherManager = new CertFetcherManager();

const fetcher = certFetcherManager.getFetcher('s3');

const certData = await fetcher.readCertificate(config.certFiles);

const gaws = new Gaws({
  organizationName: config.organizationName,
  baseUrl: config.baseUrl,
  auth: certData,
  logLevel: config.logLevel,
});

const gawsApiResponse = await gaws.programs.getAuthorized();

console.log(gawsApiResponse.data);

Config options

organizationName

The organization name is a string that identifies your organization and will appear in the headers of requests to the UW GAWS API. This helps when working with the UW Graduate School to debug your application.

baseUrl

At the moment, this module only supports the GAWS v3 api. You can use the test or production server.

auth: { cert: 'cert data', key: 'key data' }

The Graduate Applicant Web Service requires that you pass a valid UW x509 client certificate with all requests. The data returned from the request is restricted to what is authorized for your cert.

logLevel

You can set the log level to silly, trace, debug, info, warn, error, or fatal. If nothing is specified, the default level is error.

Endpoints Implemented

All the v3 endpoints except for documents have been implemented. By default, all requests are made to the JSON endpoints, if you want XML as the response set options.format to xml.
