SVG Fill

Fills all shapes of an SVG in single colour.

:warning: Currently uses a naive solution that simply adds a fill attribute with the chosen fill color to the SVG element. For SVGs without styling attributes, such as ones to be composed into a symbol sprite, this should work fine. For anything else, the results will be hit and miss.

Usage

Requirements

• Node.js >= 14

Installation

npm install --save svg-fill

API

Simple usage:

const SvgFill = require('svg-fill').default;

// Instantiante SvgFill with your chosen fill
// color:
const svgFill = new SvgFill('#FF0000');

// SvgFill expects SVG data as a string or Buffer
const originalSvgData = '<svg>....</svg>';

// Color your SVG!
const coloredSvgData = svgFill.fillSvg(originalSvgData);

Alternatively, SvgFill can provide a transform stream that you can pipe your SVG data into:

const fs = require('fs');
const SvgFill = require('svg-fill').default;

// Same setup as above
const svgFill = new SvgFill('#FF0000');

// E.g. read an SVG file, pipe it through SvgFill
// and save the result to another file:
fs.createReadStream('in.svg')
  .pipe(svgFill.fillSvgStream())
  .pipe(fs.createWriteStream('out.svg'));

Development

Setup

Clone this repo and npm install its dependencies:

git clone [email protected]:c1rrus/svg-fill.git

cd svg-fill/

npm install

Building

npm run build

This will transpile the TypeScript source code (in the src/) directory and output the results to dist/.

For development convenience, you can alternatively watch the source files and automatically trigger rebuilds when they change:

npm run watch

Running tests

npm run test

We use Jest for the tests. Each module's unit tests is located alongside its [module name].ts file as [module name].test.ts.

Linting

To help keep code consistent and avoid common gotchas, we lint our code using typescript-eslint. To run it do:

npm run lint

Commit message formatting

All commit messages must follow the Conventional Commits standard as we use automated release tools that rely on this. Commit messages are linted to check this and your CI builds will fail if your messages don't conform.

To make composing suitable commit messages easier, this repo is Commitizen friendly. We strongly recommend using commitizen rather than using git directly. To use it, simply run:

npm run commit

...and follow the prompts in your terminal.
