feat: Expression extension framework (#4372)
* ⚡ Introduce a framework for expression extension * 💡 Add some inline comments * ⚡ Introduce hash alias for encrypt * ⚡ Introduce a manual granular level approach to shadowing/overrideing extensions * 🔥 Cleanup comments * ⚡ Introduce a basic method of extension for native functions * ⚡ Add length to StringExtension * ⚡ Add number type to extension return types * ⚡ Temporarily introduce DateTime with extension * ⚡ Cleanup comments * ⚡ Organize imports * ♻️ Fix up some typings * ⚡ Fix typings * ♻️ Remove unnecessary resolve of expression * ⚡ Extensions Improvement * ♻️ Refactor EXPRESSION_EXTENSION_METHODS * ♻️ Refactor EXPRESSION_EXTENSION_METHODS * ♻️ Update extraArgs types * ♻️ Fix tests * ♻️ Fix bind type issue * ♻️ Fixing duration type issue * ♻️ Refactor to allow overrides on native methods * ♻️ Temporarily remove Date Extensions to pass tests * feat(dt-functions): introduce date expression extensions (#4045) * 🎉 Add Date Extensions into the mix * ✨ Introduce additional date extension methods * ✅ Add Date Expression Extension tests * 🔧 Add ability to debug tests * ♻️ Refactor extension for native types * 🔥 Move sayHi method to String Extension class * ♻️ Update scope when binding member methods * ✅ Add String Extension tests * feat(dt-functions): introduce array expression extensions (#4044) * ✨ Introduce Array Extensions * ✅ Add Array Expression tests * feat(dt-functions): introduce number expression extensions (#4046) * 🎉 Introduce Number Extensions * ⚡ Support more shared extensions * ⚡ Improve handling of name collision * ✅ Update tests * Fixed up tests * 🔥 Remove remove markdown * :recylce: Replace remove-markdown dependencies with implementation * ♻️ Replace remove-markdown dependencies with implementation * ✅ Update tests * ♻️ Fix scoping and cleanup * ♻️ Update comments and errors * ♻️ Fix linting errors * ➖ Remove unused dependencies * fix: expression extension not working with multiple extensions * refactor: change extension transform to be more efficient * test: update most test to work with new extend function * fix: update and fix type error in config * refactor: replace babel with recast * feat: add hashing functions to string extension * fix: removed export * test: add extension parser and transform tests * fix: vite tests breaking * refactor: remove commented out code * fix: parse dates passed from $json in extend function * refactor: review feedback changes for date extensions * refactor: review feedback changes for number extensions * fix: date extension beginningOf test * fix: broken build from merge * fix: another merge issue * refactor: address review feedback (remove ignores) * feat: new extension functions and tests * feat: non-dot notation functions * test: most of the other tests * fix: toSentenceCase for node versions below 16.6 * feat: add $if and $not expression extensions * Fix test to work on every timezone * lint: fix remaining lint issues Co-authored-by: Csaba Tuncsik <csaba@n8n.io> Co-authored-by: Omar Ajoue <krynble@gmail.com>
