@as-integrations/aws-lambda - npm Package Versions

3.1.0

Minor Changes

• #122 d1e8271 Thanks @BlenderDude! - Fixes missing decodeURIComponent during GET request parsing of query string for ALB and V1 event

3.0.0

Major Changes

• #110 e76fc08 Thanks @trevor-scheer! - Drop support for Node v14

Minor Changes

• #91 71c94df Thanks @BlenderDude! - ## Short circuit middleware execution

  You can now opt to return a Lambda result object directly from the middleware. This will cancel the middleware chain, bypass GraphQL request processing, and immediately return the Lambda result.

  Example

  export const handler = startServerAndCreateLambdaHandler(
    server,
    handlers.createAPIGatewayProxyEventV2RequestHandler(),
    {
      context: async () => {
        return {};
      },
      middleware: [
        async (event) => {
          const psk = Buffer.from('SuperSecretPSK');
          const token = Buffer.from(event.headers['X-Auth-Token']);
          if (
            psk.byteLength !== token.byteLength ||
            crypto.timingSafeEqual(psk, token)
          ) {
            return {
              statusCode: '403',
              body: 'Forbidden',
            };
          }
        },
      ],
    },
  );
  

2.0.1

Patch Changes

• #81 b59291a Thanks @0x6368656174! - fix search params duplication

2.0.0

Major Changes

• #67 5669d23 Thanks @BlenderDude! -

  Why Change?

  In the interest of supporting more event types and allowing user-extensibility, the event parsing has been re-architected. The goal with v2.0 is to allow customizability at each step in the event pipeline, leading to a higher level of Lambda event coverage (including 100% custom event requests).

  What changed?

  The second parameter introduces a handler that controls parsing and output generation based on the event type you are consuming. We support 3 event types out-of-the-box: APIGatewayProxyV1/V2 and ALB. Additionally, there is a function for creating your own event parsers in case the pre-defined ones are not sufficient.

  This update also introduces middleware, a great way to modify the request on the way in or update the result on the way out.

  startServerAndCreateLambdaHandler(
    server,
    handlers.createAPIGatewayProxyEventV2RequestHandler(),
    {
      middleware: [
        async (event) => {
          // event updates here
          return async (result) => {
            // result updates here
          };
        },
      ],
    },
  );
  

  Upgrade Path

  The upgrade from v1.x to v2.0.0 is quite simple, just update your startServerAndCreateLambdaHandler with the new request handler parameter. Example:

  import {
    startServerAndCreateLambdaHandler,
    handlers,
  } from '@as-integrations/aws-lambda';
  
  export default startServerAndCreateLambdaHandler(
    server,
    handlers.createAPIGatewayProxyEventV2RequestHandler(),
  );
  

  The 3 event handlers provided by the package are:

  • createAPIGatewayProxyEventV2RequestHandler()
  • createALBEventRequestHandler()
  • createAPIGatewayProxyEventRequestHandler()

  Each of these have an optional type parameter which you can use to extend the base event. This is useful if you are using Lambda functions with custom authorizers and need additional context in your events.

  Creating your own event parsers is now possible with handlers.createRequestHandler(). Creation of custom handlers is documented in the README.
