Stencil Version

Current Behavior

ES5 - app.js pointing to some map file which has file-path for each components, whose fingerprint/hash remains same even when the contents inside changed.

When using app.js as script src.. couldn't get the latest components from cdn as filename remains same.
Tested with v3 and v4 both has the issue.

Expected Behavior

Filename to be dynamic based on content sha.

Thanks for the issue! This issue has been labeled as needs reproduction. This label is added to issues that need a code reproduction.

Please reproduce this issue in an Stencil starter component library and provide a way for us to access it (GitHub repo, StackBlitz, etc). Without a reliable code reproduction, it is unlikely we will be able to resolve the issue, leading to it being closed.

If you have already provided a code snippet and are seeing this message, it is likely that the code snippet was not enough for our team to reproduce the issue.

For a guide on how to create a good reproduction, see our Contributing Guide.

For reproduction:

1. yarn build from main branch : https://github.com/Unluckynerd/Stencil-Components/tree/main

2. Navigate to dist/stencil-example/stencil-example.js it has filename ref to p-4d29357c.system.js

3. yarn build from patch_add_newButton branch : https://github.com/Unluckynerd/Stencil-Components/tree/patch_add_newButton

4. Navigate to dist/stencil-example/stencil-example.js, it has same filename referencep-4d29357c.system.js, but if we compare the contents of p-4d29357c.system.js it will be different.

Filename remains same for these branches.

Version used:
Stencil v4.7.0
node v18.18.0

@Aadhisivam I was able to confirm what you're seeing. I'll get this labeled and ingested into our backlog for future work!

Did a little investigation on this. The hashes that are used as filenames are generated by Rollup, so Stencil doesn't directly control how that works. I believe this issue maybe have something to do with rollup/rollup#2839, but I haven't conclusively determined that to be the case. It's possible that upgrading to Rollup v3 will fix the issue (and we may not be able to fix it without doing that unfortunately).
