BREAKING CHANGES

Slightly Breaking Changes

Node 10+

Updated the required Node version from 8 to 10.

While previous versions of TSDX began deprecating support for Node 8, it was not officially dropped. In this release, we have officially dropped Node 8: TSDX now requires Node 10+ as many dependencies that were upgraded similarly do.

This should not impact most users as Node 8 has been EoL for ~9 months now. Many packages had already required Node 10+ and the vast majority already have support for it. Most users are on Node 12 or Node 14 already.

Jest 25

Updated the Jest version used by tsdx test from 24 to 25.

The main breaking change in Jest 25 is the upgrade of the default JSDOM environment from JSDOM v11 to JSDOM v15. For most Jest users, this change either has no impact or will reduce configuration if you've manually set a more up-to-date jest-environment-jsdom in your jest.config.js. In some rare cases, where code relied on the old version of JSDOM, this may result in breakage.

ts-jest and jest-plugin-typeahead have also been upgraded to support Jest 25.

Babel Changes

babel-plugin-transform-async-to-promises -> babel-plugin-polyfill-regenerator

async-to-promises has been unmaintained for around a year now and has several correctness issues, many of which have affected TSDX users. For that reason, we've switched to using babel-plugin-polyfill-regenerator instead, which will add a pure, non-polluting regenerator-runtime polyfill if your targets require it.

The vast majority of browsers now support async/await and generators with no polyfilling necessary, but the default preset-env will add it. If you don't already have one, we recommend adding a .browserslistrc (or preset-env targets) to specify the environments you're targeting.

This should be totally backward-compatible, but it may change the output quite a bit, including making bundles larger due to inclusion of regenerator-runtime.

babel-plugin-macros

TSDX's internal Babel plugin ordering has changed, moving babel-plugin-macros to be first. This was done in order to support several use-cases like styled-components/macro, which previously did not work due to the ordering.

This shouldn't really break anything, but there is an off chance it might have an impact on some rare builds.

Improvements

• Jest 25 / JSDOM 15 usage per above
• Due to the babel-plugin-polyfill-regenerator change above, TSDX now supports polyfilling generators out-of-the-box. Previously we only supported async/await with babel-plugin-transform-async-to-promises and required users to configure their own plugins for generator polyfilling
