tldts is a JavaScript library for extracting hostnames, domains, subdomains, and public suffixes from URLs and hostnames. It also supports parsing email addresses and detecting IPv4 and IPv6, and includes TypeScript type definitions.

Recent updates

  • v7.4.2

    1 week ago

    v7.4.2 updates the bundled public suffix list and regenerates related internal data used for domain/TLD parsing. It also bumps the eslint-plugin-prettier dependency (and, via lockfile resolution, some related transitive tooling dependencies).

  • v7.4.1

    1 week ago

    v7.4.1 mainly updates the bundled public suffix list data used by tldts across the core and ICANN/experimental variants. The release also bumps a couple of build-time dependencies and adds a README benchmark throughput chart. No code-level API changes (exports or function signatures) are evident in the provided diff.

  • v7.4.0

    1 week ago

    v7.4.0 introduces a new API, getFullDomain, across tldts, tldts-icann, and tldts-experimental. It returns the normalized full hostname (subdomain plus registrable domain) when a registrable domain exists, otherwise it returns null.

    Features

  • v7.3.1

    1 week ago

    v7.3.1 introduces a targeted bug fix to reject hostnames that contain labels starting with a hyphen. The change is implemented in the core hostname validation logic and reflected by additional test coverage.

    Breaking

  • v7.3.0

    1 week ago

    v7.3.0 is positioned as a performance-focused release that validates hostnames inline during extraction to remove a redundant hostname validation scan. The code implements a validation “fusion” between `extractHostname` and `parseImpl`, and adds test coverage to lock in the intended behavior.

  • v7.2.1

    1 week ago

    v7.2.1 is a small patch release focused on hostname extraction in `tldts-core`. The main fix ensures unbracketed IPv6 literals are extracted correctly instead of being mangled/truncated, with corresponding test coverage in `tldts-tests`.

  • v7.2.0

    1 week ago

    v7.2.0 adds opt-in detection for IANA special-use domain names (RFC 6761 and extensions) and exposes the result from `parse()` as `isSpecialUse`. The feature is disabled by default to avoid extra work on the common path, and it is accompanied by new unit tests and README documentation.

    Features

  • v7.1.2

    2 weeks ago

    v7.1.2 mainly tightens IPv6 “probably an IP” heuristics and adds related tests, alongside documentation and some dependency/tooling bumps. A new defensive guard prevents a potential infinite loop in the internal base directory discovery utility.

    BreakingSecurity

  • v7.1.1

    2 weeks ago

    Release v7.1.1 is a focused polish release that updates hostname extraction behavior in tldts-core to better align with WHATWG URL host-boundary semantics. It also adds substantial test coverage by vendoring Web Platform Tests URL hostname cases and introducing dedicated unit tests for extractHostname.

  • v7.1.0

    2 weeks ago

    v7.1.0 claims performance improvements and reduced memory allocations across the main tldts packages. The release notes do not describe the underlying implementation changes, which include a significant rework of suffix trie/lookup internals and changes to how default options and hostname validation are handled.
