Sinkr

Synchronize data to your clients in real time with websockets. Deploy on your own infrastructure!

WIP

This library is WIP as I test things to make sure they work, with the goal of achieving near parity with Pusher. Use at your own risk, but if you do run into problems, PRs/issues are welcome :)

How to use

To deploy your own Sinkr instance, follow these steps:

1. Clone this repository
2. Run pnpm install in the root directory
3. In Cloudflare, ensure you have a domain you want to deploy to.
4. In GitHub, create a new GitHub OAuth app
   1. Make sure the app has the callback URL set to <your domain>/api/auth/callback/github
   2. Save your client ID and secret
5. Setup your Cloudflare workers
   1. Run cd apps/app-manager
   2. Run pnpm wrangler login to authenticate Wrangler
   3. Run pnpm wrangler d1 create <your-database-name> to create a D1 database.
   4. Copy wrangler.example.toml into wrangler.toml and fill out the values with your created bindings for both app-manager and deployment
      1. Both should use the same D1 database binding (ID and name)
      2. Each one should use a separate domain. For example, apps.example.com and ws.example.com for app-manager and deployment
   5. Run pnpm wrangler d1 execute <your-database-name> --file setup.sql --remote and confirm.
   6. Add the following environment variables to a .env file:
      1. CLOUDFLARE_ACCOUNT_ID: your Cloudflare account ID
      2. CLOUDFLARE_DATABASE_ID: the Database ID of your D1 databasae
      3. CLOUDFLARE_D1_TOKEN: the API token created in step 4
   7. Update apps/app-manager/src/server/auth.ts:32 to add your own GitHub login as an administrator
   8. Add the following Cloudflare secrets:
   9. Run pnpm wrangler secret put AUTH_SECRET
   10. Paste a random, securely generated string of characters. I recommend using openssl rand -base64 32
   11. Run pnpm wrangler secret put AUTH_GITHUB_ID
   12. Paste your GitHub OAuth client ID from the app created in step 3
   13. Run pnpm wrangler secret put AUTH_GITHUB_SECRET
   14. Paste your GitHub OAuth client secret from the app created in step 3
   15. Run pnpm run deploy to deploy your App Manager
   16. Run cd ../deployment
   17. Run pnpm run deploy to deploy your Websocket manager
   18. Link your app manager and worker to your domain.
       1. Make sure the subdomain you choose for your app manager matches the url you put into GitHub
6. Install the SDK in your app code
   1. For TypeScript apps of any kind, simply install @sinkr/core from JSR.
   2. For React apps, install @sinkr/react from JSR. This also exports @sinkr/core so installing both is not strictly necessary.
   3. For Python apps of any kind, install sinkr from PyPI
7. Done! Start sending and receiving messages!
