TooGoodToGoBot

Too Good To Go is an app that looks to solve food waste by providing a platform to connect restaurants with excess food and consumers looking for great deals. I use the app frequently looking for deals on tasty food items that I would probably purchase at full price anyways. There's one feature the app is missing though; notifications.

TooGoodToGoBot is my solution to this feature via a service run fully on AWS that integrates with Discord bot APIs to send discord notifications upon store restocks. Note that TooGoodToGoBot is unaffiliated with Too Good To Go and any usage is done so at your own risk.

Setup

In the future, I may plan to create a centralized bot that can be added directly to servers to subscribe specific accounts, but in the meantime it is possible to completely setup this service for your own use.

Installation

Dependencies: Node.js

git clone https://github.com/jackie-z528/TooGoodToGoBot.git
cd TooGoodToGoBot
npm i

Discord Bot

Create a discord application and a discord bot under the application. Make a note of the bot token somewhere.

AWS Setup

Create an AWS account, note that a credit card is required, but as long as this service is used correctly, your account will remain under the free tier limits for DynamoDB and Lambda by a huge margin.

Serverless Setup

• Create a serverless dashboard account
• Create a new app too-good-to-go-bot
• Create a new service too-good-to-go-bot under the app too-good-to-go-bot
• Go into the settings of too-good-to-go-bot service and add 3 paramaters:
  • discordToken: token for your discord bot
  • tableName: name you want for the DynamoDB table
  • awsRegion: probably us-east-1
• Modify the first line of serverless.yml org: <orgname> to the orgname of your serverless account
• Run serverless in the project directory and follow the steps to setup the AWS services

Login

After the AWS Lambdas are deployed, you should see output in the console with the login endpoint. Run the login command by sending a post request to <loginendpoint>/login/:email and wait for a login request from Too Good To Go to be sent to your email. Click the login button in the email on a browser. Do not click it on a phone with Too Good To Go installed, this will not work. Then send a post request to <loginendpoint>/login/:email/continue and wait for Login Succeeded. The polling lambda will now run successfully.

Setting Up Discord Notifications

To enable discord notifications, add the bot you created to a server of your choice. In the server, right click the channel you'd like to receive the notifications in and click Copy ID. In the AWS console, add a new item to the dynamoDB with { key: "subscribedChannels", valueList: [id]}.

Usage

The bot will poll the Too Good To Go API every minute and send a notification to the subscribed channels whenever there is an increase in stock.
