💰 borrow-bot

A data collection bot and website aimed at helping lenders make good choices at /r/borrow.


  • Node.js (Version 5 and up recommended)
  • MySQL server


  • Clone down the repository
git clone https://github.com/snollygolly/borrow-bot.git
  • Install packages (from inside the borrow-bot folder)
npm install
  • Create your config. There's a config.json.example file in the root. Edit it to include all your values for the database, Reddit, Twilio, and the website. Save it as config.json and leave it in the root.

  • Connect to your MySQL server and create a database called borrow-bot with the following options

Database Encoding: utf8
Database Collation: utf8_general_ci
  • Create the table schema
npm run migrate


There are two main components to BorrowBot. One is the ingestion bot, and the other is the website.


The ingestion bot is best run on a cronjob. Reddit has fairly lax throttling limits, so once a minute is a good interval to run it. There currently isn't any way to update or create historical records, so BorrowBot will only ever pick up the most recent 25-30.


  • To start the ingestion bot, run the following:
npm run bot-start


The bot also comes with a collection of test posts (posts.json). These are posts that real users have created, but that the bot initially got wrong when parsing. We take these posts, manually enter the correct values, and then test the bot's logic against this.

  • To move over a single post from the posts table to the test posts file (posts.json)
npm run bot-import ID

Note: When running bot-import, be sure to manually go into the post's record in MySQL and update the borrow, repay, interest, currency, and repay date's values to the correct ones.

  • To run all the tests with summarized output AND save the results back (results.json)
npm run bot-test-summary

Note: If you've made changes to the test posts file (posts.json) or the BorrowBot logic, please make sure you run bot-test-summary before you commit, so you know how effective your changes were.

  • To run all the tests with full output
npm run bot-test


The website portion is used to take the data the ingestion bot collects and display it in an easy to use interface.


  • To start the website, run the following:
npm start
