Browserify version 1.10.0 introduces notable enhancements and dependency adjustments compared to the preceding stable release, version 1.9.4, offering developers improved functionality for browser-side module management. Both versions remain committed to providing a require() function for JavaScript directories and npm modules within the browser environment, simplifying front-end development workflows.
A key change in version 1.10.0 is the updated dependency specifications. Specifically, resolve is now constrained to version "~0.2.0", while in 1.9.4 it allowed a broader range ">0.0.4 <0.1." Also, version 1.10.0 adds vm-browserify and http-browserify as core dependencies, enriching the library's capabilities by providing browser-compatible replacements for Node.js's vm and http modules. Conversely, coffee-script has a tighter version constraint of "~1.1.1" in 1.10.0 compared to ">=1.1.1 <1.2" in 1.9.4.
Furthermore, there are shifts in the devDependencies. Version 1.10.0 drops jsdom, a testing framework, but introduces ecstatic, a simple static file server. These adjustments showcase a refinement in the tools utilized for testing and development. Developers migrating to version 1.10.0 should carefully examine the impact of these altered dependencies on their projects and existing code. The inclusion of vm-browserify and http-browserify might simplify the process of using Node.js core modules within the browser, while the modified version constraints of the other core dependencies require scrutiny to avoid compatibility issues.
