Eslint-plugin-expect-type version 0.0.1 introduces an intriguing tool for TypeScript developers seeking enhanced type safety within their ESLint workflows. This initial release focuses on enabling type assertion capabilities directly within your tests and code, using the $ExpectType and $ExpectError directives within comments. These special comments empower developers to explicitly assert the expected type of an expression or to verify that a specific code snippet indeed results in a type error, providing valuable in-line validation.
Prior to version 0.0.1, developers relied on manual type checking or alternative testing methodologies to confirm the correctness of their TypeScript types. This plugin streamlines the process, integrating type assertions directly into the ESLint environment for immediate feedback during development. It avoids running the code, because it only lints the code. This can speed up testing.
The plugin's core functionality hinges on parsing and interpreting these custom directives during ESLint's linting process. It compares the asserted type against the actual type inferred by the TypeScript compiler, reporting any discrepancies as ESLint errors. Version 0.0.1 provides a foundational set of rules for $ExpectType and $ExpectError, offering a basic, yet powerful, mechanism for type-driven development and improved code quality. Note that no information about a presumed previous version is available. Developers beginning with this package should note the dependencies, including key TypeScript and ESLint related packages, ensure compatibility within their project setup for optimal functionality.
