# `@probot/adapter-aws-lambda-serverless`

> Adapter to run a [Probot](https://probot.github.io/) application function in [AWS Lambda](https://aws.amazon.com/lambda/) using the [Serverless Framework](https://github.com/serverless/serverless)

[![Build Status](https://github.com/probot/adapter-aws-lambda-serverless/workflows/Test/badge.svg)](https://github.com/probot/adapter-aws-lambda-serverless/actions)

## Usage

```shell
npm install @probot/adapter-aws-lambda-serverless
```

```javascript
// handler.js
const {
createLambdaFunction,
createProbot,
} = require("@probot/adapter-aws-lambda-serverless");
const appFn = require("./");
module.exports.lambdaFn = createLambdaFunction(appFn, {
probot: createProbot(),
});
```

## Configuration

You need to add [environment variables to configure Probot](https://probot.github.io/docs/configuration/) to your Lambda function. If you use the [Serverless App](https://app.serverless.com/), you can add parameters for `APP_ID`, `PRIVATE_KEY`, `WEBHOOK_SECRET`, the use these parameters in `serverless.yaml`.

```yml
provider:
name: aws
runtime: nodejs12.x
lambdaHashingVersion: 20201221
environment:
APP_ID: ${param:APP_ID}
PRIVATE_KEY: ${param:PRIVATE_KEY}
WEBHOOK_SECRET: ${param:WEBHOOK_SECRET}
NODE_ENV: production
LOG_LEVEL: debug

functions:
probot:
handler: handler.lambdaFn
events:
- httpApi:
path: /api/github/webhooks
method: post
```

Make sure to configure your GitHub App registration's webhook URL to `/api/github/webhooks`.

## Test deployment

For testing your Probot deployment without end to end (GitHub) integration, you can use this shell snippet:

```shell
$ LAMBDA_URL=https://x.execute-api.y.amazonaws.com/stage-or-basePath/api/github/webhooks
$ SECRET=the_webhook_secret
$ TMP_DATA_FILE=/tmp/smoke.data

$ echo -n "{\"action\":\"test\"}" > $TMP_DATA_FILE
$ SIGN=$(openssl dgst -sha1 -hmac $SECRET $TMP_DATA_FILE | cut -d" " -f2)
$ curl --request POST --header "X-Hub-Signature: sha1=$SIGN" --header "X-Github-Event: test" --header "X-GitHub-Delivery: fake" --data-binary "@$TMP_DATA_FILE" $LAMBDA_URL
{"ok":true} <-- Concent for Probot v10: {"message":"Received test.test"}
```
