## Install
This package is [pure ESM](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c). If you're not ready yet, install an older version of this program, 3.1.0 (`npm i color-shorthand-hex-to-six-digit@3.1.0`).
```bash
npm i color-shorthand-hex-to-six-digit
```
## Quick Take
```js
import { strict as assert } from "assert";
import { conv } from "color-shorthand-hex-to-six-digit";
// converts shorthand hex color codes within strings (imagine that could be
// email template source code):
assert.equal(
conv("aaaa #f0c zzzz\n\t\t\t#fc0"),
"aaaa #ff00cc zzzz\n\t\t\t#ffcc00",
);
// converts shorthand hex colour codes within plain objects:
assert.deepEqual(
conv({
a: "#ffcc00",
b: "#f0c",
c: "text",
}),
{
a: "#ffcc00",
b: "#ff00cc",
c: "text",
},
);
// converts shorthand hex colour codes within arrays:
assert.deepEqual(conv(["#fc0", "#f0c", "text", ""]), [
"#ffcc00",
"#ff00cc",
"text",
"",
]);
// converts shorthand hex colour codes within nested spaghetti's:
assert.deepEqual(
conv([[[[[[{ x: ["#fc0"] }]]]]], { z: "#f0c" }, ["text"], { y: "" }]),
[[[[[[{ x: ["#ffcc00"] }]]]]], { z: "#ff00cc" }, ["text"], { y: "" }],
);
// in all other cases it silently returns the input:
assert.equal(conv(null), null);
```
