A simple Discord bot that aims to provide a snapshot of the join logs given a range of time for servers

? What is Humpy Dumpy?

Humpy Dumpy is a simple Discord bot that aims to provide a snapshot of the join logs given a range of time for servers. It was created as a little boredom-reliever based on an idea that came from suggestions of Beemo‘s Discord server which people wanted a simple and easy way to dump join logs.

? Public Bot

Humpy Dumpy can be invited to your server with no permissions required, you can invite the publicly hosted bot if you do not want to self host: https://discord.com/api/oauth2/authorize?client_id=1009426851208384552&permissions=0&scope=applications.commands%20bot

? How does Humpy Dumpy work?

Humpy Dumpy works with the combination of MongoDB and Javacord to receive and store a snapshot of the user’s information and related information onto a time-series collection to allow massive datasets with very little storage usage and performance impact (200k users was around 900 kilobytes of storage space according to MongoDB Compass).

Humpy Dumpy uses Javalin as its web framework to enable server moderators to receive a snapshot of the server’s join logs at a given time range. To learn more about how to query with the HTTP API, please read the section below.

❓ Humpy Dumpy Flow

Humpy Dumpy provides a privacy-safe and simple HTTP API for server moderators to request their server join logs within a given timestamp but before we delve into how each query works, let us first understand the different routes available.

• /range.json: This route enables for a full JSON representation of the server logs, this contains all the information needed like user name, discriminator, join timestamp, etc.
• /range.txt: This route is a more simpler version of the JSON route and returns a plain-text content that contains only the users snowflakes (intended for mass banning).

Now that we have understood what the different routes means, let us delve into the query parameters available for each one.

? JSON Route

? Plain-text Route

? Modified RFC 1132 Date Time

To make it more human-friendly to read, all routes uses a Modified RFC 1132 (17 Aug 2022, 16:34:12 UTC) variant for its parameters. It’s the same as the RFC 1132 Date Time (Wed, 17 Aug 2022, 16:34:12 UTC) but without the week of the day (Wed) which can be a mess to modify and cause issues for the end-user.

? Minutes Ago Since Now

Minutes ago since now should be self-explanatory, it is the minutes ago since now. To understand this, let us say that our current time is 06:30 and we set a minutes ago since now to 30 minutes, our new time would be 06:00 because the minutes ago since now would reduce the current time by the given value (30 minutes).

? JSON Web Token

JSON Web Token is an authentication or security identifier that should not be disclosed easily to others. All tokens generated by Humpy Dumpy have a maximum time limit of one (1) hour to prevent a misuse of the authentication token. Please keep this token as safe as possible unless you want your join logs to be viewed by other people.

? Acquiring a JSON Web Token

Acquiring a JSON Web Token is as simple as running the /token slash command on the server that you want to use the token on. A token is limited to only one server and you cannot use it to view other servers that you own or manage. A token have a maximum of one hour expiration and configureable down to five minutes to ensure that it is not used to expose joinlogs (invading privacy) of the server if it happens to be accidentally exposed (always recommend using as less time as possible for token lifespan).

? Sharing Logs

A best practice with Humpy Dumpy over sharing logs is to actually copy the response, saving it somewhere like GitHub Gist and sending it to whomever you like. It is not recommended to share the actual link that contains the token at all because it leaves a chance for the join logs other than the selected points of time to be exposed.

? Example Requests

To understand how our requests look, let us say that we want to query our server’s recent 30 minutes joins, we can simply open a new browser tab and run the following:

http://humpydumpy.mihou.pw/range.json?server=<server_id>&after=30&token=<token>

The following query requests for all recent joins after (current_time – 30 minutes).

❓ Self-hosting

You can self-host Humpy Dumpy by following the instructions below:

1. Clone the repository.

git clone https://github.com/ShindouMihou/HumpyDumpy && cd HumpyDumpy

2. Create a Mongo database. You can create a free MongoDB database via Atlas RECOMMENDED for beginners or by self-hosting.
3. Configure the .env by running the following command (Linux):

cp .env.example .env && nano .env

4. Build the Docker image.

docker build -t humpydumpy .

5. Run the Docker image.

docker run --name humpydumpy --env-file .env -p 2004:2004 -d -i -t humpydumpy:latest
