Overview

The @hvniel/vite-plugin-svelte-inline-component is an innovative tool designed to streamline the testing of Svelte components within JavaScript and TypeScript environments. By allowing developers to write tiny Svelte components directly in their test files using tagged-template literals, it simplifies the testing process by eliminating the need for separate .svelte files. The plugin effectively compiles Svelte code on the fly, making it a game-changer for SvelteKit projects that leverage Vitest for testing.

What sets this plugin apart is its ability to maintain clean production builds while enabling inline component testing. This capability is particularly beneficial for developers looking for rapid iterative testing without sacrificing the integrity of their production code.

Features

• Inline Svelte Components: Write Svelte components directly in your test files using tagged-template literals, streamlining your testing process.

• Virtual Module Compilation: Automatically compiles Svelte markup and replaces it with virtual modules, eliminating the need for additional files.

• Definition Fences: Share code across multiple inline components using specially marked comment blocks, ensuring your imports and variables are accessible.

• Named Exports: Utilize <script context="module"> for named exports, making components versatile and reusable within tests.

• TypeScript Integration: Enhance TypeScript support with type assertions for named exports, allowing for a better development experience.

• Compatibility with Testing Libraries: Works seamlessly with Vitest and popular libraries like @testing-library/svelte, making it easy to test components effectively.

• Customizable Options: Modify default settings to tailor the plugin’s behavior, including tag names for inline Svelte markup and the definition fence comments.
