canvas-poster crossposts all posts and announcements from Canvas into Discord, with a button to view the original post in Canvas.
Based on ed-poster.
canvas-poster runs on Cloudflare Workers for free.
You will need:
- A Cloudflare account
- Node.js installed locally
- A Discord server, where you have Manage Webhook permissions
First, clone this repository and run pnpm i. (If pnpm isn't installed, run corepack enable first.) Copy wrangler.example.toml to wrangler.toml and courses.example.json to courses.json.
Create an Canvas access token. Run pnpm set-token and type in the API token when prompted. You may be prompted to log in to your Cloudflare account first.
Run pnpm create-kv, then copy the provided binding ID into wrangler.toml.
In courses.json, set the courseID to a unique string for the course, and set canvasID to the numeric course ID in the Canvas URL.
Use Webhook Creator to create a webhook in the channel and get the URL. (Don't create the webhook in Discord settings, use this tool instead.) Copy the URL it gives you and set it as announcementWebhook in courses.json.
When you're done, run pnpm run deploy. canvas-poster will now check every minute for new Canvas announcements and send them to the appropriate Discord channel.
