Signal Flags

Flag images for International Code of Signals Flags.

Getting started: Signal Flags Loader

To use the automagic Signal Flags Loader see the Example Page.

Getting started without the Loader

To use in an HTML page, load from jsDelivr:

<script src="https://cdn.jsdelivr.net/npm/signal-flags@2/dist/signal-flags.min.js"></script>

To use in Node.js install using npm npm i signal-flags or yarn yarn install signal-flags

const SignalFlags = require('signal-flags');

Usage

// Get the SVG string for a flag.
SignalFlags.get('a');
// ... with no outline.
SignalFlags.get('a', { outline: false });
// ... as a standalone file.
SignalFlags.get('a', { file: true });
// ... as a Data URI for inserting into an IMG tag.
SignalFlags.get('a', { dataUri: true });
// ... using the `primary` colour set.
SignalFlags.get('a', { colors: 'primary });
// ... overriding one or more colours.
SignalFlags.get('a', { colors: white: '#ffffff' });
// ... square option for rectangular flags.
SignalFlags.get('ap', { shape: 'square' });
// ... long option for pennants.
SignalFlags.get('ap', { shape: 'long' });

// Get the SVG strings for all flags (keyed by the flag name).
SignalFlags.all();
// ... with options.
SignalFlags.all({ outline: false, file: true });

Current release v2.4.0

• Design improvements:
  • Reverted triangles to 4:3 ratio.
  • Default pennants are now 3:1 (this was previously the long option which is now removed), with a new short option for the previously default 2:1.
