Essentials

Sprig essentials are a small set of composable primitives rather than a large component runtime:

• State: Core signal() for scalar values; optional createStore() from sprig-framework/store for plain object/array state.
• Derivation: computed() for a read-only derived getter.
• Side effects: effect() for tracked work, with a disposer.
• Rendering: h() or a compiled .sprig template.
• Lifetime: createRoot() and onCleanup() for ownership and cleanup.

The guides below cover application setup, templates, and reactivity. Sprig does not provide Vue's Options API or Vue-compatible component lifecycle.
