eslint-plugin-preact-signals

ESLint plugin for type-aware linting of usage of Preact Signals, including from @preact/signals-core, @preact/signals, and @preact/signals-react.

Installation

Add the preact-signals plugin to your ESLint configuration, and then you can reference the rules in your config.

Rules

• preact-signals/no-implicit-boolean-signal: disallow the implicit coercion of variables that can contain a Signal to a boolean value. This is useful for preventing accidental omissions of .value or .peek().
  • Options:
    • allowNullishCoalesce:
      • false: disallow implicit coercion via ??
      • nullish (default): allow implicit coercion via ?? when the signal variable may be null
      • always: allow all uses of ?? with signals
