RxJS 6.0.0 marks a significant shift from version 5.5.12, presenting both opportunities and adjustments for developers. One immediately noticeable change is the dependency structure. RxJS 6.0.0 relies heavily on tslib, indicating a stronger focus on TypeScript compilation and potentially smaller bundle sizes for TypeScript-based projects. In contrast, RxJS 5.5.12 depended solely on symbol-observable.
Beyond core dependencies, a large change in the devDependencies reveals a modernization of the build and testing process in RxJS 6. Notable additions and updates include @angular-devkit/schematics and @angular-devkit/build-optimizer, which suggests tighter integration and optimization with Angular projects. Version 6 leverages newer versions of testing frameworks such as Chai, Mocha, and Sinon, indicating improved testing infrastructure and reliability. The inclusion of tools like dependency-cruiser for dependency analysis provides developers with insights into their codebase's structure. While RxJS 5 used typings, this is fully removed in RxJS 6 because typescript offers this natively.
Developers should be mindful of potential breaking changes arising from these dependency updates and architectural improvements and consider updating their code accordingly. The updated toolchain likely brings performance benefits, but this comes at the cost of adapting to the changing landscape of the RxJS ecosystem. Overall, the upgrade is a positive step towards a more modern and efficient reactive programming experience.
