## Introduction

This is the code and documentation that accompanies the Big Sky Dev Con 2018 presentation "Building a Serverless Backend". During this presentation, we built an SMS/MMS-based meme generator service.

## Quick Start

First, put your twilio creds into  4-memegen/config/deploy.yml. Then:

```

npm install

cp -R lambda-native-canvas/node_modules/lambda-canvas node_modules/

cd 4-memegen

npx sls deploy --stage develop

```

## Project Layout

Each step taken in the presentation is laid out in a numbered folder. I organized the repo this way so that you can easily flip back and forth between implementations. This structure relies on appropriate symlinks - if your operating system doesn't handle symlinks well, you may need to copy `node_modules`, `src`, `lib`, `images`, `package.json`, `serverless.json` into the subdirectories

* 0-hello-serverless - The initial Hello World serverless function

* 1-http-and-debugging - A Lambda invoked via HTTP and debugging

* 2-chaining - A lambda chained to another via SNS and SQS

* 3-deployment-and-environments - Full environments, full local debugging

* 4-memegen - The full service

## Running Locally

Running locally is a bit more involved than running in the cloud:

### Prerequisites

* [brew](https://brew.sh/)

* node 8+

* Python 3

* [pipenv](https://github.com/pypa/pipenv)

### Steps

```

npm i

npm i -g serverless # or you can use npx

cp -R lambda-native-canvas/node_modules/lambda-canvas node_modules/

brew install cairo # necessary for node-canvas

pipenv install --dev # for localstack

SERVICES=s3,sqs,sns pipenv run localstack start

cd 4-memegen/

# The next command builds the localstack resources

sls runWithEnvironment --command 'node src/local-bootstrap.js' --stage local

```

Once this is all complete, you should be able to run with

```

sls offline start

```

Alternatively, you can use the [VSCode](https://code.visualstudio.com/) to debug your lambdas. Simply use the Serverless Offline debug target.

### Other Directories

* images/ - the meme images. Feel free to add your own!

* src/ - Library code

* lambda-native-canvas/ - A build of canvas against the linux runtime used by Lambda
