tsdkbundle: Bun-Powered Multi-Entry TypeScript Bundling

This walkthrough rebuilds an operable path for: tsdkbundle: A Bun-Based TypeScript Multi-Entry Bundler. Focus on contracts, checks, and code you can drop into a repo without guessing intent. For Overview, define the inputs, the owner of the step, and the exit criteria before changing code. Operators should be able to re-run the step from a known checkpoint without guessing hidden state. Prefer small, testable units over sprawling scripts. When a step fails, the failure should point at a single responsibility.

Why Bun?

For Why Bun?, define the inputs, the owner of the step, and the exit criteria before changing code. Operators should be able to re-run the step from a known checkpoint without guessing hidden state. Treat this stage as a contract between inputs and validated outputs. Name the artifacts, define success checks, and refuse silent partial completion. Understand what truly blocks the event loop versus what only awaits. Synchronous exceptions are the classic trap.

Use Cases

For Use Cases, define the inputs, the owner of the step, and the exit criteria before changing code. Operators should be able to re-run the step from a known checkpoint without guessing hidden state. Record timings and cost next to functional results. Visibility early prevents surprise bills in shared environments. Understand what truly blocks the event loop versus what only awaits. Synchronous exceptions are the classic trap.

Operational checklist

For Operational checklist, define the inputs, the owner of the step, and the exit criteria before changing code. Operators should be able to re-run the step from a known checkpoint without guessing hidden state.

Document the happy path and the recovery path together. Retries and dead-letter handling are part of the product.

Prefer structured concurrency patterns over fire-and-forget promises that swallow failures.

Prefer boring reliability over clever one-off demos.

Prefer small, testable units over sprawling scripts. When a step fails, the failure should point at a single responsibility.

Prefer structured concurrency patterns over fire-and-forget promises that swallow failures.

Before promoting the stack, freeze versions, capture a golden transcript for the critical path, and confirm rollback steps. Shared environments need rate limits, tenancy checks, and a clear owner for secret rotation.

For hardening note 0, define the inputs, the owner of the step, and the exit criteria before changing code. Operators should be able to re-run the step from a known checkpoint without guessing hidden state.

Keep configuration outside application code. Environment files, secret stores, and feature flags belong in one place operators can audit.

Pin runtime versions and record the digest that ran the demo.
