banner-proxy

An AWS Lambda function for retrieving and caching data from Ellucian Banner via the BannerJS module.

Invoking

Invoke the Lambda using banner-proxy:<QUALIFIER>, where <QUALIFIER> can be either a version number or alias (recommended to use the live alias as it has been tested and is stable).

All payloads should adhere to the following JSON format:

{
  school: <STRING>,
  term: <NUMBER>,
  method: <STRING>, #See BannerJS documentation for a list of methods
  params: {<PARAMS>} #Optional, arguments to pass to the BannerJS method being called. See the BannerJS documentation for more info
}

Deploying

Note: the BannerJS module and AWS CLI are needed for this section.

To deploy the Lambda to AWS:

1. Clone both this repository and the BannerJS repository locally.
2. Run /path/to/bannerjs/deploy.sh | /path/to/banner proxy/deploy.sh

Unit tests

This repo contains a Mocha test suite, utilizing a mocked Banner library.

To run the unit tests:

1. Run npm install to install the rewire mocking dependency.

• If Mocha is not installed, run npm install -g mocha

2. Run npm test or mocha to run the test suite.

Integration tests

Note: the AWS CLI needs to be installed and configured for this section.

The repo also contains a series of integration tests meant to be run against the deployed Lambda on AWS (where it has access to the Banner module via a custom layer). These can be found in test/integration_tests.json and can be run with the Unit Testing Lambda via the test/integration_tests.sh shell script, which will log the results to integration_test_results.json.

Sample JSON for Lambda console test events:

{
  "school": "temple",
  "term": 202036,
  "method": "classSearch",
  "params": {
    "term": 202036,
    "subject": "MATH",
    "offset": 0,
    "pageSize": 25
  }
}

{
  "school": "temple",
  "term": 202036,
  "method": "getCampuses"
}

{
  "school": "temple",
  "term": 202036,
  "method": "getInstructors",
  "params": {
    "term": 202036
  }
}

This test event should throw an error:

{
  "school": "temple",
  "foo": "foo",
  "bar": "bar"
}
