Webpack test repo

For testing out webpack configurations/plugins

To build use npm run build

npm run build creates two bundles: bundle.js (app code) and vendor.js (third-party code)

This uses a webpack plugin to create a hash based on the name, author, major version, and minor version of a package. This plugin is used as a module identifier.

The idea is, if a build of vendor.js doesn't alter the patch (z in x.y.z) versions of any packages, it should be consistent with any existing bundles.

In addition to the bundles webpack creates a records.json file, which shows module identifiers.

To test out the concept do the following:

1. npm i
2. npm run build
3. cp records.json /tmp/records.json
4. change the z-version of a package in package.json, i.e. change jquery from 3.3.1 to 3.3.0
5. npm i
6. npm run build
7. diff records.json /tmp/record.old.json There should be no difference here as no major or minor versions were changed.
8. change the y-version of a package in package.json, i.e. change jquery from 3.3.0 to 3.2.0
9. npm i
10. npm run build
11. diff records.json /tmp/record.old.json Now you should see a difference in hashes since the a y-version has changed.
