Building

Reproducible building

You can build the exact same bytecode

npm run compile && npm run prepack

Then check that all the files are the same using npm diff

npm diff

If the output is empty then the bytecode is the same as the one I published on NPM.

Automated checks

Each time I release a new version on GitHub, the GitHub's CI clones the GitHub repository, reproduces the build, and throws an error if the NPM release is different. If a version is present on NPM but not on GitHub, do not use it!
