Blixter

Blixter in an open-source streaming platform that i created to improve my frontend and backend skills and knowledge

It's a typescript monorepo that use typescript for the backend and sveltekit for the frontend

It's deployed on a self-hosted k3s cluster an it's powered by the bun javascript runtime

It relies on postgres as the primary db and redis for the cache, pub-sub and queues.

The files are stored on minio, an S3 compatible object storage

Task Runner

The Task Runner script is a versatile tool:

• It locates and runs scripts specified in the cli args for each project (if the project has that script).
• It handles log formatting, code checks with prettier, code generation, and project linting with tsc.
• In development mode, it runs all apps in parallel and triggers the code generation scripts when specified files change. It also applies Prettier code formatting and regenerates generated or cached files.
• In test mode, it runs the .test.ts file specified in the script arguments.
• In other modes, it run the code generation on startup, checks TypeScript types with TSC, ensures code formatting with Prettier and reports errors if tasks fail.
