Description:

Credentials in env.js to hit the Tools API from a local setup:

window.__env.API_LOCATION = 'https://r9f4ib8x0m.execute-api.ca-central-1.amazonaws.com';
window.__env.API_PATH = '/dev';
window.__env.API_PUBLIC_PATH = '/dev';

# 291 - Move A&R to use SAM

• A complete overhaul of the deployment strategy of BC Parks Attendance & Revenue API to use AWS's Serverless Application Model (SAM).

• This includes migrating the functions into their equivalent SAM functions, changing util functions into applicable layers, converting/reintegrating tests to use SAM, and removing any Terraform legacy code

• uses an Authorizer (authorizer/index.js) to process the JWT from Keycloak and create the necessary IAM roles for each function

• sets up the API in API Gateway using the Authorizer

• creates a new ParksAr, ConfigAr, and NameCacheAr tables in DynamoDB

• create a new S3 bucket for export assets

• dependent on additional tickets (322, 323, 342, 343)

# 322 - Update Functions

• builds the Lambda functions using SAM, update dependency and other import paths, add respective package.json files for each Lambda's required dependencies
• configure roles/permissions to be expected from the event, as they are now decoded in the Authorizer
• fixes to export and variance export and their invokables - now use v3 SDK and properly upload to the S3 bucket
  • VarianceExportGetFunction altered slightly to more closely resemble ExportGetFunction (was easier to debug during update).

# 323 - Create Layers

• create any necessary layers from the utils files
  • merge the logger, sendResponse, and the dynamoUtils file into a BaseLayer file to circumvent the five-layer restriction set by AWS
• add Makefiles to build layers

# 342 - Convert Tests

• Remove old tests files and directories and convert/integrate them to use the SAM configuration
  • roles come from the event so roles/permissions are allocated in the headers of the tests
• update Postman environment paths (will need updating once fully built in dev/test/prod), fix a few typos and tests
• update READMEs accordingly to reflect changes

# 343 - Cleanup Terraform and non-SAM Code

• updates the .github/wokflows deploy actions to build and deploy the SAM files in each AWS environment
• pull out all Terraform deployment files and strategies
• update the READMEs to reflect the new start up procedures for local startup, AWS deployment, etc.
