Wrong Quote Bot

This is a Twitter bot (@onlywrongquotes) that publishes random quotes, quoting the wrong person.

The project is hosted in AWS, and the deployment is implemented with AWS CDK.

The lib/ folder has the code that creates the stack itself (WrongQuoteBotStack) which provisions a Cloudwatch rule that triggers a lambda function every 2 hours. The lambda gets a random quote, a random name, and tweets it out.

Setup

To get access to the Twitter API you'll need to create a new App with Read and Write access. More info on that here, then create a .env file based on the info in .env.example:

TWITTER_API_KEY=
TWITTER_API_SECRET=

TWITTER_ACCESS_TOKEN=
TWITTER_ACCESS_SECRET=

Building/Deploying

The lambda code is hosted in the lambda/ folder - before deploying you'll need to run npm install in both the root project and the lambda folder.

In the root directory:

cd lambda
npm install      // download lambda's dependencies
cd ..
npm install      // download cdk's dependencies
tsc

This will download npm modules for both the infrastructure and the lambda code itself, and compile the typescript to javascript.

Making Changes

The bin directory contains the binary that creates the infrastructure, which is a Cloudformation stack from the definition in the lib folder.

The logic for the bot is in the lambda folder. The code and node_modules is a separate project within the project that gets sent to AWS when you deploy the lambda.

To test the quotes you can run the npm script below, which will print a test tweet and the quotes from the different sources (this was easier than trying to set up Jest within the lambda directory):

cd lambda
npm run print

Output:

> tweet-lambda@1.0.0 print [path-to-project]/wrong-quote-bot/lambda
> tsc && node src/print.js

Whether you change the lambda or the infrastructure, simply run tsc or npm run build from the root directory, which will convert the code to Javascript.

Deploy

Run cdk deploy. This will deploy / redeploy your Stack to your AWS Account.

You'll need to download the CDK CLI if you don't have it already:

npm install -g aws-cdk

And set up your AWS account and credentials with aws configure.

Commands

• npm run build compile typescript to js
• cdk deploy deploy this stack to your default AWS account/region
• cdk diff compare deployed stack with current state
• cdk synth prints the generated CloudFormation template
