\n\n> Check if an NPM package name is taken.\n\nValidates an NPM package name and then checks if a conflicting package exists. Also accounts for [punctuation differences](https://blog.npmjs.org/post/168978377570/new-package-moniker-rules).\n\n\n## Installation\n\n```bash\nyarn add is-name-taken\n```\n\n```bash\nnpm install is-name-taken\n```\n## API\n\n```ts\nimport { isTaken, isValid } from \"is-name-taken\";\n\n// Check if a package name is taken, and if so, return the conflict:\n\nisTaken(\"ch-alk\"); // \"chalk\"\n\n// If not taken, return false\n\nisTaken(\"package-that-doesnt-exist\"); // false\n\n// If invalid, return true\n\nisTaken(\"INVALID_NAME\"); // true\n\n// Check if a package name is valid\n\nisValid(\"chalk\"); // true\n\nisValid(\"INVALID_NAME\"); // false\n\n```\n#### Types:\n```ts\nimport { Options } from \"is-name-taken\";\n\ntype Options = {\n /**\n * Maximum milliseconds after a sync to avoid re-syncing\n */\n maxAge?: number;\n /**\n * Setting optimistic to true will skip syncing latest packages from NPM.\n * This is faster, but may lead to inconsistencies with recently published packages.\n */\n optimistic?: boolean;\n};\n\nfunction isValid(name: string): boolean;\n\nfunction isTaken(name: string, options?: Options): Promise;\n```\n\n##\n\n
