By default, styler outputs stylers for HTML and SVG elements. It’s possible to create a styler for any JavaScript API that might benefit from render batching or cached state.

For this, we can use the createStylerFactory function.



import { createStylerFactory } from 'stylefire';

Create a styler factory

createStylerFactory accepts an object of properties:


This method is fired when the styler’s get is called and no property with this name is present in the state cache (or useCache is set to false).

(key: string, props: {}): any


This method is fired on the render step, or if the styler’s render method is called manually.

(state: {}, props: {}, changedValues: string[]): void


Set to false if you always want onRead to fire when a user calls get.

Using the styler factory

createStylerFactory returns a styler factory:

const myStylerFactory = createStylerFactory({ onRead, onRender });

This is a function that accepts one argument, an object of props. These props can be anything - they are for you to use in onRead and onRender methods.

Here’s an incredibly simple example of a styler that simply reads and writes any object provided to it:

import { createStylerFactory } from 'stylefire';

const exampleStyler = createStylerFactory({
  onRead: (key, props) => props[key],
  onRender: (state, props, changedValues) => {
    changedValues.forEach(key => (props[key] = state[key]));

const myExampleStyler = exampleStyler({ red: 255, green: 255, blue: 255 });
myExampleStyler.set('green', 0);
