TL;DR: Use Reacord

psst! This project isn't deprecated or anything (yet?), but I'm moving away from its development for a few reasons:

• The command handling part is limited, and doesn't accomodate the use cases that a decent portion of bots need, e.g. being able to add a command for individual guilds
• The reactivity part has gaps, and is also enforced in every case, including cases where it might be suboptimal

For that reason, I split out the reactivity part into a new library: Reacord. It allows you to leverage JSX, react state, as well as the react ecosystem, and is much more powerful than what gatekeeper offers to accomplish the same goal. I would recommend using Reacord if declarative and reactive messages are what you're looking for.

For command handling, I can't recommend a library for that (yet?), but you'll probably be able to build your own simple command handler.

gatekeeper

Gatekeeper is a ✨reactive✨ interaction framework for discord.js!

• API Docs

Install:

# npm
npm install @itsmapleleaf/gatekeeper discord.js

# yarn
yarn add @itsmapleleaf/gatekeeper discord.js

# pnpm
pnpm add @itsmapleleaf/gatekeeper discord.js

Here's a taste of what Gatekeeper looks like:

import { buttonComponent, Gatekeeper } from "@itsmapleleaf/gatekeeper"
import { Client, Intents } from "discord.js"

const client = new Client({
  intents: [Intents.FLAGS.GUILDS],
})

;(async () => {
  const gatekeeper = await Gatekeeper.create({
    client,
  })

  gatekeeper.addSlashCommand({
    name: "counter",
    description: "make a counter",
    run(context) {
      let count = 0

      context.reply(() => [
        `button pressed ${count} times`,
        buttonComponent({
          style: "PRIMARY",
          label: "press it",
          onClick: () => {
            count += 1
          },
        }),
      ])
    },
  })

  await client.login(process.env.BOT_TOKEN)
})()

And a silly example, demonstrating the power of the library. You can find the code here
