Laraue Software Blog — C# .NET Development & Open Source

Part 13 of building a Telegram task tracker solo. Users asked for a web version outside Telegram, so it needed its own login. Adding the Telegram Login Widget meant a second validation scheme alongside the Mini App's — and both end at the same JWT, because the app barely depends on Telegram past login.

Part 11 of building a Telegram task tracker solo. Teaching the capture bot to handle photos and video, and the storage decision behind it — keep small previews on disk, stream full files straight from Telegram on demand without buffering them in memory, using nginx range-request passthrough, instead of re-hosting everything.

Part 9 of building a Telegram task tracker solo. The issue layer in the web app and the database design decision at its centre — when a nullable foreign key is the wrong choice and a dedicated default row is better, using issues, epics and the backlog as the example.

Part 8 of building a Telegram task tracker solo. The full Telegram Mini App authentication flow in a real .NET and Nuxt app — validating the initData signature on the server with HMAC-SHA256, issuing and using a JWT bearer, reading the user from HttpContext, and why CORS matters.
