🤖 Hans - Discord Bot

Hans is built with a modular architecture that makes it easy to add and remove functionality on the fly, empowering you to create a bot tailored to your community's needs.

Built with Discord.JS, TypeScript, and lots of ❤️

Invite to server

Bring Hans to your Discord server and start using his available features immediately here 🔗. It uses the latest hans:nightly image with the latest features.

The list of commands & plugins can be found here 🔗

Developing Hans

🪬 NOTE: Please consider opening an issue and PR for bugs, suggestions, or new features.

🔅 Prepare environment

Before running any command, run npm install && cp .env.template .env, and fill in all the env variables needed. To create your application, visit Discord's Developer Portal

🪬 IMPORTANT: A Supabase instance is needed for the bot to work. A free cluster should be more than enough (even for small bots & communities) for development.

Supabase Local Development.

Supabase is used for storing the bot's configs, guilds, and users.

You can work with supabase local, follow the instructions here 🔗. Once you run supabase start the local Supabase will be populated with the latest schema (have a look at the supabase/seed.template.sql file for more configuration)

More information related to working with Supabase local development can be found 📹 here 🔗

👩🏼‍💻 Development

Once the Prepare environment section is done, you can follow along with the development.

npm run dev

It will start a development server with ts-node and nodemon for live-reload. A bot Invite link will be displayed in the console.

Slash commands

All commands (under src/commands) are built with the Slash Command interaction.

🪬 IMPORTANT: before developing commands, make sure you invite the bot to your server and the entry in Supabase configs -> bot_guild_id is your guild_id.

All commands under the main folder are available globally (it will take a second to have them available) while the ones under bots-playground/ are guild-specific and are instantly deployed, use this folder for debugging & development purposes.

To deploy the commands: npm run slashDev or npm run slash in production.

🧪 Unit Tests

For testing, we use Mocha with TS.

All the tests are under the /tests directory. Right now they're none or a few, we should add more test coverage for command controllers.

npm run test

Will run all the tests.

---

🏗 Production

We have multiple environments for deploying your bot.

With Docker

You can either use the pre-built Docker image from DockerHub at en3sis/hans:latest or build your own locally using the command docker build -t en3sis/hans .

To run the container, use the command docker run --env-file .env --name hans -d --restart=always en3sis/hans:latest while making sure that the .env file is in the same directory as the command and contains all the necessary environment variables for the bot to function properly. You can also run it with docker-compose using the command docker-compose up -d --build bot.

Note: for M1 Macs, you'll need to use docker-compose build --build-arg M1=true before running the docker-compose up -d.

Locally

You can also run the bot locally using the following commands:

🪬 IMPORTANT: Follow the Prepare environment section.

npm run build

To generate the application's build.

npm start

It will run the bot with the production environment.

With Kubernetes (WIP)

💢 NOTE: This is a WIP, it's not fully tested yet, things are missing. Please feel free to contribute.

It's also possible to deploy the bot to a Kubernetes cluster, the necessary files are in the k8s folder.

Steps:

1. You'll need your K8S cluster, ofc ;P
2. Create the namespace kubectl apply -f k8s/namespace.yaml
3. Run cp k8s/secrets.template.yaml k8s/secrets.yaml, fill it up and apply the secrets kubectl apply -f k8s/secrets.yaml
4. Deploy the workload kubectl apply -f k8s/deployment.yaml
