Esbuild Svelte
An esbuild plugin to compile Svelte components
Overview
The esbuild-svelte plugin is a tool that allows developers to compile Svelte components for bundling with esbuild. It provides a simple build script for getting started quickly and supports features such as CSS output, Typescript and other Svelte preprocessing, importing Svelte component libraries, and advanced caching for incremental or watch builds. The plugin also has a comprehensive API that includes support for Svelte's compiler options and preprocessing API.
Features
- Compile Svelte components: The plugin allows developers to compile Svelte components for bundling with esbuild.
- CSS output: By default, the plugin emits external CSS files from Svelte for esbuild to process. However, developers can configure it to include CSS in the JavaScript output instead.
- Typescript and other Svelte preprocessing: The plugin supports Typescript and other languages that require preprocessing before being fed into the Svelte compiler. Developers can easily add preprocessors to the plugin's configuration.
- Svelte component library support: When importing a Svelte component library, developers need to add "svelte" to the conditions in esbuild build options. This allows esbuild to use the svelte property in the library's exports conditions in package.json.
- Advanced caching: For incremental or watch build modes, esbuild-svelte automatically caches files that haven't changed. This allows esbuild to skip the Svelte compiler for those files, saving time. Developers can disable this caching by setting the cache option to false.
- Svelte
Svelte is a modern front-end framework that compiles your code at build time, resulting in smaller and faster applications. It uses a reactive approach to update the DOM, allowing for high performance and a smoother user experience.
- SCSS
SCSS is a preprocessor scripting language that extends the capabilities of CSS by adding features such as variables, nesting, and mixins. It allows developers to write more efficient and maintainable CSS code, and helps to streamline the development process by reducing repetition and increasing reusability.
- Typescript
TypeScript is a superset of JavaScript, providing optional static typing, classes, interfaces, and other features that help developers write more maintainable and scalable code. TypeScript's static typing system can catch errors at compile-time, making it easier to build and maintain large applications.
