srcset-parse

An extra small srcset attribute parser compliant with the latest spec. Unlike srcset package, supports:

• URLs that contain commas;
• Zero or one descriptors per image definitions (like 2x or 100w, but not both!).

Example usage:

1import parse from "srcset-parse";
2
3/**
4 * [
5 *   { url: "hifi-cat.jpeg",  density: 3 },
6 *   { url: "lowfi-cat.jpeg", width: 128 },
7 * ]
8 */
9parse("hifi-cat.jpeg 3x, lowfi-cat.jpeg 128w");

Using with TypeScript

The library is written in TypeScript, so you can import types if needed:

1import parse, { ImageCandidate } from "srcset-parse";
2
3const result: ImageCandidate[] = parse("icon@2x.png 2x, icon.png 1x");

Platform support

This library is written according to the ES2015 standard. Make sure your platform supports it, or your project is configured to transpile external modules.
