caniname

Check availability of a project name across services (Netlify, NPM, and more).

Fun fact: This tool was originally built under the name namecheck. Upon running ./bin/namecheck.js namecheck to dogfood it before publishing, it turned out that namecheck was already taken on both Netlify and NPM—so we used the tool itself to find an available name: caniname.

Usage

npx caniname formula-input
npx caniname formula-input calc-input

Or run locally:

./bin/caniname.js formula-input calc-input

Options

• -j, --json: Output results as JSON
• -h, --help: Show help message

Adding New Checks

Each check lives in its own file inside src/checks/. Any .js file placed in src/checks/ is automatically discovered and executed in parallel.

To add a new check, create src/checks/<service>.js with the following shape:

export async function check(name) {
	const normalized = name.trim().toLowerCase();
	const target = `${normalized}.example.com`;
	const url = `https://${target}`;

	// Perform availability check...
	const available = true;

	return {
		id: 'example',
		name: 'Example',
		target,
		url,
		available,
	};
}

export default {
	id: 'example',
	name: 'Example',
	check,
};
