📋 Initial Topics for the Bundler Collaboration Space

These are the initial topics selected for the Bundler Collaboration Space. Each topic has a dedicated sub-issue with research, per-bundler comparisons, and proposed areas for collaboration.

---

Priority Topics

• Module Resolution: Aligning package.json exports, conditional exports, and resolution algorithms across bundlers #7 — Module Resolution
• import.meta Behavior: Standardizing behavior across bundlers and runtimes #8 — import.meta Behavior
• HMR Protocol: Toward a shared hot-module-replacement contract #9 — HMR Protocol
• Tree Shaking Alignment: Toward consistent dead-code elimination across bundlers #10 — Tree Shaking Alignment

---

Follow-up Topics

• Source Map Consistency: Bundlers differ in handling multi-step transformations and chaining — consistent behavior would improve debugging. (@nicolo-ribaudo, @AriPerkkio) [1] [2]

• Code Splitting Conventions: Code splitting strategies and chunk naming differ across bundlers — shared conventions would help caching and migrations. (@sokra, @evanw)

• AST Serialization Format: A shared serialization format for parse trees could enable new tooling and easier migration between bundlers. (@nicolo-ribaudo, @overlookmotel)

• Runtime Behavior Alignment: Differences in generated runtime code cause subtle bugs — documenting and aligning key behaviors would improve predictability. (@sokra, @yyx990803)

We at Codemod can help turn whatever this group standardizes into safe migrations, so teams can actually adopt the standards instead of just reading them. I try to keep up with updates, but if you come across cases where standards or best practices could be codified as codemods for the community, please ping me. Thanks!
