This package will allow for header based routing/versioning in APIs. It will follow Cox API Cookbook standards listed here: https://ghe.coxautoinc.com/CoxAuto/api-cookbook/blob/master/cookbook-v2.md#8-api-versioning
In order to use this, you simply can instantiate a copy of the generic class CoxHeaderApiVersionManager or the API Gateway specific class ApiGatewayCoxApiVersionManager. The API Gateway specific class has an additional function to read ApiGatewayProxyEvent and determine the version.
const versisonManager = new CoxHeaderApiVersionManager(DEFAULT_VERSION);
const version = versionManager.read(httpMethod, headers);
console.log(version);
const handler: Handler<APIGatewayProxyEvent> = async (event, context): Promise<APIGatewayProxyResult> => {
const versionManager = new ApiGatewayCoxApiVersionManager(DEFAULT_VERSION);
const version = versionManager.readApiGateway(event);
console.log(version);
}
