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
