Solid Signals

Composable signals for SolidJS

All composable signals will extend the base SolidJS signal API by adding properties to accessors and setters, all fully typed.

Solid Signals

Installation

$ npm install solid-signals

Usage

Basic

This example uses createHistory, see other signals in the Signals section

const [state, setState] = createHistory(0);

state(); // => 0
// Accessor extension
state.history(); // => [0]

setState(1);
state(); // => 1
state.history(); // => [0, 1]

// Setter extension
setState.back();
state(); // => 0
state.history(); // => [0]

setState.forward();
state(); // => 1
state.history(); // => [0, 1]

Composition

Signal composition is achieved by wrapping other signals with the .wrap method. This allows you to extend a signal with as many features as you’d like instead of using a single feature set provided by a traditional signal.

import { createArray, createHistory } from "solid-signals";

const [state, setState] = createHistory.wrap(createArray<number>([]));

// setState.push is provided by createArray
setState.push(1); // state() => [1]
setState.push(1, 2, 3); // state() => [1, 2, 3]

// setState.history.back is provided by createHistory
setState.history.back(); // state() => [1]

// Accessors can also be extended
// state.history is provided by createHistory
state.history(); // => [[], [1]]

Signals

Creating your own composable signal

(This api is not finalized)

You can create your own composable signal by using the signalExtender api, see createObject for an example
