42.0.0 / 2020-12-06

This release includes several contributor patches. Thanks @sorhtyre @mattruzzi !

  • [BREAKING CHANGE] Warn on old Electron/Chrome (fix #556) (PR #1076) ⚠️ Users packaging kiosk apps running for a long time on internal websites, see https://github.com/nativefier/nativefier/blob/master/docs/api.md#disable-old-build-warning-yesiknowitisinsecure

  • Migrate from Travis CI to GitHub Actions
  • Bump default Electron to 11.0.3, bump dep eslint-config-prettier to 7.x

Also, bumping npm version to something far away from current Electron version.

Rationale for the nonsensical major version bump: around Nativefier 8.x, versions of Nativefier and Electron aligned, by release schedule coincidence. Since Nativefier has little breaking changes, it was great: as Electron releases are breaking, Nativefier had no breaking changes, I bumped our major version on new major Electron, and everything was good.

Except now, as I have a breaking change, which would bump Nativefier to 12.x, being annoyingly confusing since we'd still default to Electron 11 :-/ .

-> To keep respecting semver and reduce confusion, bumping Nativefier version to something far ahead of Electron versions. No it doesn't matter, version number are meaningless anyway (well, outside of semver, whose respect is precisely the point here).

Revamp and move to TypeScript (#898)

Breaking changes

Changes summary

Nativefier didn't get much love recently, to the point that it's becoming hard to run on recent Node, due to old dependencies. Also, some past practices now seem weird, as better expressible by modern JS/TS, discouraging contributions including mine.

Addressing this, and one thing leading to another, came a bigger-than-expected revamp, aiming at making Nativefier more lean, stable, future-proof, user-friendly and dev-friendly, while not changing the CLI/programmatic interfaces. Highlights:

  • Require Node>=8, as imposed by many of our dependencies. Node 8 is twice LTS, and easily available even in conservative Linux distros. No reason not to demand it.
  • Default to Electron 8.
  • Bump all dependencies to latest version, including electron-packager.
  • Move to TS. TS is great. As of today, I see no reason not to use it, and fight interface bugs at runtime rather than at compile time. With that, get rid of everything Babel/Webpack.
  • Move away from Gulp. Gulp's selling point is perf via streaming, but for small builds like Nativefier, npm tasks are plenty good and less dependency bloat. Gulp was the driver for this PR: broken on Node 12, and I didn't feel like just upgrading and keeping it.
  • Add tons of verbose logs everywhere it makes sense, to have a fine & clear trace of the program flow. This will be helpful to debug user-reported issues, and already helped me fix a few bugs.
    • With better simple logging, get rid of the quirky and buggy progress bar based on package progress. Nice logging (minimal by default, the verbose logging mentioned above is only used when passing --verbose) is better and one less dependency.
  • Dump async package, a relic from old callback-hell early Node. Also dump a few other micro-packages unnecessary now.
  • A first pass of code cleanup thanks to modern JS/TS features: fixes, simplifications, jsdoc type annotations to types, etc.
  • Remove GitHub integrations Hound & CodeClimate, which are more exotic than good'ol'linters, and whose signal-to-noise ratio is too low.
  • Quality: Add tests and add Windows + macOS CI builds. Also, add a manual test script, helping to quickly verify the hard-to-programatically-test stuff before releases, and limit regressions.
  • Fix a very small number of existing bugs. The goal of this PR was not to fix bugs, but to get Nativefier in better shape to do so. Bugfixes will come later. Still, these got addressed:
