GP Seattle Inventory APIs

This package contains different APIs that perform operations against the relevant DynamoDB tables.

APIs

There are a list of APIs that have been implemented in the api folder. The API classes all contain the following:

• public constructor(client: DBClient, metrics?: MetricsClient)
  • Public constructor to initialize the API class. Requires a DBClient, which main current implementation is DDBClient. Optionally, accepts a MetricsClient, which main current implementation is CloudWatchClient.
• public static NAME: string
  • This is the name used to initialize the router transaction
• public router(number: string, request: string, scratch?: ScratchInterface): string | Promise<string>
  • This is the main function that is used to understand router requests.
• public execute(scratch: ScratchInterface): Promise<?>
  • This is the main function that is used to execute the specific API. This is the function that should be used to call the API from code.
• interface ScratchInterface
  • Interface defining the variables that are expected for the execute function. Note that this interface is not exported.

Router

One way the APIs are linked up is through the router, where a user can either use a SMS or CLI (for dev) dialogue to invoke APIs.

The SMS router is invoked through sending a message to the designated number, which triggers a SNS notification, which in turn triggers a Lambda invocation of the SMS router code.

A CLI router was created for the purposes of testing, which can be invoked by pulling the code, then running the following:

• npm install
• npm run build
• From the __dev__/handlers/router directory: node CLIRouter.js
