/** * The interface that AWS Lambda will invoke your handler with. * There are more specialized types for many cases where AWS services * invoke your lambda, but you can directly use this type for when you are invoking * your lambda directly. * * See tme {@link http://docs.aws.amazon.com/lambda/latest/dg/nodejs-prog-model-handler.html AWS documentation} * for more information about the runtime behavior, and the * {@link https://aws.amazon.com/blogs/compute/node-js-8-10-runtime-now-available-in-aws-lambda/ AWS Blog post} * introducing the async handler behavior in the 8.10 runtime. * * @example <caption>Defining a custom handler type</caption> * import { Handler } from 'aws-lambda' * * interface NameEvent { * fullName: string * } * interface NameResult { * firstName: string * middleNames: string * lastName: string * } * type PersonHandler = Handler<NameEvent, NameResult> * * export const handler: PersonHandler = async (event) => { * const names = event.fullName.split(' ') * const firstName = names.shift() * const lastName = names.pop() * return { firstName, middleNames: names, lastName } * } * * @example <caption>Logs the contents of the event object and returns the location of the logs</caption> * import { Handler } from 'aws-lambda' * * export const handler: Handler = async (event, context) => { * console.log("EVENT: \n" + JSON.stringify(event, null, 2)) * return context.logStreamName * } * * @example <caption>AWS SDK with Async Function and Promises</caption> * import { Handler } from 'aws-lambda' * import AWS from 'aws-sdk' * * const s3 = new AWS.S3() * * export const handler: Handler = async (event) => { * const response = await s3.listBuckets().promise() * return response?.Buckets.map((bucket) => bucket.Name) * } * * @example <caption>HTTP Request with Callback</caption> * import { Handler } from 'aws-lambda' * import https from 'https' * * let url = "https://docs.aws.amazon.com/lambda/latest/dg/welcome.html" * * export const handler: Handler<void, number> = (event, context, callback) => { * https.get(url, (res) => { * callback(null, res.statusCode) * }).on('error', (e) => { * callback(Error(e)) * }) * } * * @param event * Parsed JSON data in the lambda request payload. For an AWS service triggered * lambda this should be in the format of a type ending in Event, for example the * S3Handler receives an event of type S3Event. * @param context * Runtime contextual information of the current invocation, for example the caller * identity, available memory and time remaining, legacy completion callbacks, and * a mutable property controlling when the lambda execution completes. * @param callback * NodeJS-style completion callback that the AWS Lambda runtime will provide that can * be used to provide the lambda result payload value, or any execution error. Can * instead return a promise that resolves with the result payload value or rejects * with the execution error. * @return * A promise that resolves with the lambda result payload value, or rejects with the * execution error.
