    An error handler middleware for AWS http lambda functions, compatible with http-errors.

    Lambda middleware

    This middleware is part of the lambda middleware series. It can be used independently.

    Usage

    import { errorHandler } from "@lambda-middleware/errorHandler";
    import { APIGatewayEvent, APIGatewayProxyResult } from "aws-lambda";
    import createHttpError from "http-errors";
    
    // This is your AWS handler
    async function helloWorld(
      event: APIGatewayEvent
    ): Promise<APIGatewayProxyResult> {
      if (event.queryStringParameters?.search == null) {
        // If you throw an error with status code, the error will be returned as stringified JSON
        // Only the stack will be omitted.
        throw createHttpError(400, "Query has to include a search");
      }
    
      // If you throw an error with no status code, only a generic message will be shown to the user
      // instead of the full error
      throw new Error("Search is not implemented yet");
    }
    
    // Wrap the handler with the middleware
    export const handler = errorHandler()(helloWorld);
