Svelte Helpers · BookMD

Svelte helpers with @atom-forge/svelte-helpers @atom-forge/svelte-helpers is a small TypeScript library for Svelte 5. It gives you consistent prop types, two type utilities for variant props, a few runtime helpers, and one component that adapts snippets to component-based APIs. This book explains when each export is useful, how to combine them, and which limitations to know about. What you will learn How to type component props consistently, model mutually exclusive variants, pick a variant from boolean props, assert types in templates, debounce input handlers, and render snippets where a component is expected. Reading path Overview — scope, installation, and what is exported. Prop types — ClassProp, AnyProp, ChildrenProp, ChildrenPropOptional . Variant props — XOR, AtLeastOne, and variantMap . Runtime helpers — as, debounce, debounceAsync, and RenderSnippet . Recipes and pitfalls — a combined component and a list of limitations. Examples Snippets assume application-specific values and types (such as Item or api) are already defined. twMerge is an external helper, not part of this package.
