Ts-jest version 26.5.2 is a minor update to the popular preprocessor that enables developers to use TypeScript with the Jest testing framework. Comparing it to the previous version, 26.5.1, we observe mostly internal changes and improvements rather than significant API-breaking modifications. Both versions maintain compatibility with Jest versions 26.x and TypeScript versions 3.8 up to, but not including, version 5.0, as indicated by their peer dependencies.
A notable addition in version 26.5.2 is the json-schema-to-typescript dependency in the devDependencies, suggesting potential enhancements or modifications in how ts-jest handles and generates TypeScript definitions from JSON schemas. This may be related to improved configuration or type handling within the tool. Furthermore, version 26.5.2 includes 2 more files in the package and the unpacked size is also bigger, suggesting potentially new features or maybe even just internal new test files. For developers already using ts-jest, upgrading to 26.5.2 should be a seamless experience. However, developers are encouraged to verify that the updated json-schema-to-typescript integration, if applicable to their use case, aligns with their existing workflows. Ts-jest continues to offer source maps support and facilitates a smooth development process for TypeScript projects utilizing Jest for testing.
