alien-signals is an extremely lightweight TypeScript signal library implementing a push-pull based reactivity algorithm. Its core algorithm has been ported into Vue 3.6 and is used in Vue language tools for incremental AST parsing and virtual code generation.

Use cases

• add fine-grained reactive state to a JavaScript app
• use signals without pulling in a full framework
• benchmark or study reactivity algorithms
• build a custom reactive UI framework
• incremental computation for language tooling

When to choose

• you need minimal-bundle, high-performance signals in TypeScript
• you want a framework-agnostic reactivity primitive
• you're building tooling that benefits from incremental recomputation

When to avoid

• you want a batteries-included state manager with devtools and middleware
• you need framework-specific integrations out of the box
• you prefer a mature ecosystem over a research-oriented library
