Patch Changes

• Soft-fail when auto tsconfig discovery loads a broken config, and keep relative extends paths relative. (by @xiaoxiaojx in #645)

Patch Changes

• Keep the original request resolvable when extensionAlias lists its own extension. (by @alexander-akait in #641)

• Fix string restrictions boundary checks: a restriction ending with a separator no longer rejects everything inside it, restrictions are normalized before they are compared, and a Windows path now matches the way path.win32 does, treating / and \ as interchangeable and comparing case-insensitively, while \ stays a filename character in a posix path. The same comparison backs tsconfig path matching. (by @alexander-akait in #643)

• Treat a UNC path (\\server\share\…) as a Windows path, so it normalizes, joins and walks up with path.win32 semantics instead of being taken for a bare module request. (by @alexander-akait in #644)

Patch Changes

• Resolve tsconfig extends package specifiers from ancestor node_modules directories (workspace hoisting). (by @alexander-akait in #631)

Patch Changes

• Batch cached filesystem callbacks from one synchronous burst into a single tick. (by @alexander-akait in #623)

Patch Changes

• Reduce hot-path allocations in the resolve pipeline. (by @xiaoxiaojx in #615)

Minor Changes

• Allow the context path and request arguments of resolve (and resolveSync/resolvePromise) to accept file: URL instances, converting them to filesystem paths. Plain strings stay literal paths, matching Node's fs. (by @alexander-akait in #607)

Patch Changes

• Make the resolver runtime-agnostic so it works in browsers, Deno and Bun as well as Node. File contents are decoded without assuming a Node Buffer, and browser shims are provided for the path, url and graceful-fs builtins (Node, Deno and Bun keep using the native ones) so the package bundles for the browser — supply your own fileSystem there. (by @alexander-akait in #606)

• Rename the positional resolve/resolveSync/resolvePromise parameters to parent/specifier (from path/request) for ESM-aligned naming and document them in the README. Purely cosmetic — arguments are positional, so there is no behavior or API change. (by @alexander-akait in #611)

Minor Changes

• Allow the path-like resolve options roots, modules, alias/fallback targets, restrictions, and tsconfig (the config file, configFile, baseUrl, and references) to accept file URL instances (such as new URL("./dir/", import.meta.url)), converting them to filesystem paths. Plain strings are still treated as literal paths, matching Node's fs. (by @alexander-akait in #604)

Patch Changes

• Fall back to the next modules entry when a package exports target is filtered out by restrictions, instead of throwing. (by @alexander-akait in #600)

Patch Changes

• Fix restrictions bypass via an in-root symlink pointing outside the root. (by @alexander-akait in #595)

Minor Changes

• CachedInputFileSystem#purge accepts a second { exact?: boolean } argument; exact: true removes only entries whose key matches what exactly instead of any entry whose key starts with what. (by @alexander-akait in #591)
