# Discord Question of the Day
2
+
3
+
A Deno cron job that fetches questions from a Google Sheets endpoint and posts them sequentially to Discord via webhook. Uses Deno KV for state management to track question progression.
4
+
5
+
## Setup
6
+
7
+
0. Install [Deno](https://deno.com/), `git clone` the project and run `deno install` to install dependencies.
8
+
1. Create `.env` file for local development and fill in your values (see below)
9
+
2. Deploy to Deno Deploy or run locally
10
+
11
+
## Commands
12
+
13
+
```bash
14
+
# Local testing (with optional date/index override)
15
+
deno task dev
16
+
deno task dev --d="2025-10-25" --i="12"
17
+
18
+
# Run locally with cron
19
+
deno task run
20
+
21
+
# Deploy to Deno Deploy
22
+
deno task deploy
23
+
```

This project fetches a JSON-ified list of questions from an endpoint, a Google Sheet in our case, and runs a cron job that will successively post the questions to a Discord webhook.

Idea by @meylemonade.bsky.social
27
+
- `SHEET_ENDPOINT` - JSON endpoint URL (Google Sheets, etc.)
28
+
- `CRON_STRING` - Cron schedule expression
29
+
- `DISCORD_WEBHOOK_URL` - Discord webhook URL
30
+
- `SUGGESTION_FORM_URL` - Form to suggest new questions
31
+
- `DENO_KV_DATABASE_ID` - Deno Deploy KV database ID (for local testing)
32
+
- `DENO_KV_ACCESS_TOKEN` - Deno Deploy KV access token (for local testing)

This file is for local testing. Run `deno task dev` to use.

The command will accept optional the input parameters `date`
4

and `index`. Example usage:
5
+
6
+
deno task dev --i="12"
7
+
(will fetch today's theme, but question of index 12)
8
+
9
+
deno task dev --d="2025-10-25"
10
+
(will fetch the theme for October 25, but the current index)
11

12

You will need to set the DENO_KV_DATABASE_ID and

DENO_KV_ACCESS_TOKEN environment variables if you are using

Deno Deploy.
