chunkhash of produced assets changes even if source stays the same

[sheerun]

Hey,

I tried to use your plugin, but the chunkhash of my vendor chunk changes even if I don't modify any of my vendor dependencies.. Here is my configuration:

    new SplitByPathPlugin([
      {
        name: 'vendor',
        path: path.join(__dirname, 'node_modules')
      }
    ])

Any tips?

I only changed application code.

The vendor file differs only in following:

79c79
< /******/                      script.src = __webpack_require__.p + "" + ({"0":"index"}[chunkId]||chunkId) + "-" + {"0":"e87843f64ed5fbf75cab"}[chunkId] + ".js";
---
> /******/                      script.src = __webpack_require__.p + "" + ({"0":"index"}[chunkId]||chunkId) + "-" + {"0":"556dee5231cea6b6d18a"}[chunkId] + ".js";
25564c25564
< //# sourceMappingURL=vendor-e2ddf7a8873cca94ab3b.js.map
\ No newline at end of file
---
> //# sourceMappingURL=vendor-ef861294c72026118f27.js.map
\ No newline at end of file

Can you please provide sample project where this can be reproduced? I'll try to debug it

[sheerun]

It' the default one you provided in the readme:
https://github.com/sheerun/webpack-split

Please change v2 to v3 in index.js, and notice that vendor contents and chunkhash changes upon rebuild

[sheerun]

The comment in vendor bundle says:

/******/    // This file contains only the entry chunk.
/******/    // The chunk loading function for additional chunks

Shouldn't it be the other way around? The index chunk should be entry chunk and load vendor one..

+1, the hash of seldom changed vendor.js should not change every compilation

The main idea there is to extract manifest chunk that changes every time.

Sorry, I don't have much free time now, so I can't quickly fix this issue, but I will be able to accept PR if someone will make one.

[e-cloud]

so should we separate the manifest module to a standalone chunk as built-in behavior of this plugin or just an option?

[BohdanTkachenko]

@e-cloud did a pull request that seems to be fixing this issue. Closing this issue for now. Please re-open it if there still any problems
