fela-hashed v0.1.0

fela-hashed

This enhancer modifies fela to emit atomic class and keyframe using declaration content hashes instead of the default incremental unique ID. The generated identifiers are deterministic across executions and environments.

Installation

yarn add fela-hashed

or

npm i --save fela-hashed

Usage

import {createRenderer} from 'fela';
import hashed from 'fela-hashed';

const renderer = createRenderer({
  enhancers: [hashed()],
});

const rule = () => ({
  color: 'red',
  backgroundColor: 'blue',
});

renderer.renderRule(rule);

outputs

._87ec8632 {
  color: red;
}

._1e5ffb80 {
  background-color: blue;
}

Configuration

If you are have devMode enabled on the renderer, fela-hashed will emit verbose descriptive class names.

import {createRenderer} from 'fela';
import hashed from 'fela-hashed';

const renderer = createRenderer({
  enhancers: [hashed()],
  devMode: true,
});

const rule = () => ({
  color: 'red',
  backgroundColor: 'blue',
});

renderer.renderRule(rule);

outputs

.color_red_87ec8632 {
  color: red;
}

.backgroundColor_blue_1e5ffb80 {
  background-color: blue;
}
