Ts-loader is a TypeScript loader for webpack, streamlining the integration of TypeScript code into webpack-based projects. Examining versions 3.0.2 and 2.3.7, we observe key differences primarily in their development dependencies, specifically webpack. Version 3.0.2 upgrades to webpack version 3.6.0, whereas version 2.3.7 relies on webpack 2.2.0. This is a significant change, as webpack 3 introduced "scope hoisting," which can lead to smaller bundle sizes and faster execution by reducing the overhead of individual module wrappers.
Both versions share a common set of core dependencies, including chalk for colorful console output, semver for version management, loader-utils for webpack loader utilities, and enhanced-resolve for advanced module resolution. These remain consistent indicating stable support for the core functionality of the library across versions.
For developers, this means when upgrading to ts-loader 3.0.2, ensure compatibility with webpack 3.6.0 or higher to leverage its performance benefits. Otherwise stay on ts-loader 2.3.7 if your webpack configuration is based on the v2 version and you don't want to migrate. The update doesn't fundamentally change how ts-loader operates but brings the potential for optimized webpack builds. Before undertaking the upgrade, developers should review the webpack 3.x migration guide. Both versions support TypeScript 2.4.2.
