feat: route pkg@version from deps, direct nav, and search for any valid specifier - #1723
Dependency links with version ranges (e.g. ^18.0.0 || ^19.0.0, >15 <=16.0.2) currently navigate to a non-existent version page and result in a 404.
Searching for nuxt@4.0.1 or nuxt@>=4 or nuxt@>=4<6 (convenient if pasting from somewhere) does not result in a match. There's a proposed temporary solution in feat: strip version info from the search query #1626 to strip the version segment from the query.
📚 Description
Keep links to a single package version as is, but for all other version specifiers, link to the package page with the "Filter by semver" input pre-populated! (In the future if/when we have a dedicated versions page we could link to that instead.)
Rather than implementing this logic at the "where to link to" layer, I implemented this in the routing layer, i.e. https://npmx.dev/package/nuxt/v/:version will route to the specific versioned package page if version is a specific version string and route to the package page with ?semver=<version> otherwise.
... which means we get a fix to Add possibility to search for specific version of a package #1416 almost for free! This PR makes it so that searching for nuxt@4.0.1 or nuxt@>=4 or nuxt@>=4<6 and pressing Enter now navigates directly to the package version page for a specific version or to the semver-filtered package page for a semver specifier, instead of returning no results. This just works for both exact versions and semver ranges, because of the above routing change.

Summary
Summary by CodeRabbit
New Features
Search for a package with a specific version or dist-tag and jump directly to its version page.
Search with a semver range to open the package page with matching versions filtered.
Filter package versions using a semver range in the URL; filters update when the query changes.
Documentation
Added guidance on version-specific searches, URL-based filters and using semver ranges across the app.
Tests
Added coverage for package search and navigation across exact versions, ranges, dist-tags and scoped packages.
Search now accepts package specifications with versions. Exact versions and dist-tags route to version pages, while semver ranges route to package pages with a version filter. The versions view reads and applies the filter from the URL.
Changes: Package version navigation
Layer / File(s)
Summary
Route exact versions and semver specs app/utils/router.ts, test/unit/app/utils/router.spec.ts
Exact versions and values that do not parse as ranges route to version pages, with whitespace removed from the version. Other version values route to package pages with a semver query and a default #versions anchor. Unit tests cover package and diff routes.
Search submission parses package names and versions. Versioned searches navigate to package or version pages; other searches continue through the existing search flow. Tests cover scoped and unscoped names, exact versions, ranges, dist-tags, and plain package names.
Initialise and load version filters app/components/Package/Versions.vue, docs/content/2.guide/3.url-structure.md
The versions view reads the semver query on mount and when it changes. Its loader trims the filter and skips empty or invalid ranges. The documentation describes filtered package URLs.
npmx-dev/npmx.dev#2192: Both PRs affect dependency version links and routing semver ranges.
npmx-dev/npmx.dev#3373: This PR changes helpers used by the package-spec parsing and routing implementation.
Merge Risk: Low · up to 4506c
Mergeable with bounded follow-up: removing the semver query can leave the version list filtered, and the URL instructions need clarification for links with existing query parameters.

Explanation
The active issue [#1416] requires package@version searches to open the package with the requested version selected. parsePackageSpec handles package names with versions. packageRoute sends exact versions and dist-tags to package-version. It sends semver ranges to the package route with ?semver= and the versions section hash. Package/Versions.vue loads the filter from that query. Unit and end-to-end tests cover exact versions, scoped packages, ranges, and plain package names. Issue [#1120] is closed and supplies context only.
Full details: Out of Scope Changes check
Explanation
The changes stay within the linked feature scope. Router and search changes implement version-aware navigation. Versions filtering supports the new semver URL. Tests verify the routing and parsing behaviour. Documentation describes the implemented search and filtering behaviour. No unrelated product change is shown in the reviewed changes.

🧹 Nitpick comments (3)
shared/utils/parse-package-param.ts (1)
54-61: Trailing @ edge case may produce unexpected results.
When the input ends with @ but has no version (e.g., 'esbuild@'), the function returns { name: 'esbuild@' } because the version slice is empty. This retains the trailing @ in the package name, which is not a valid npm package name.
Consider whether this should instead return { name: 'esbuild' } to strip the trailing @:
💡 Suggested fix
export function parsePackageSpecifier(input: string): { name: string; version?: string } {
const atIndex = input.startsWith('@') ? input.indexOf('@', 1) : input.indexOf('@')
if (atIndex > 0) {
const version = input.slice(atIndex + 1)
if (version) return { name: input.slice(0, atIndex), version }
+ // Trailing @ with no version - return name without the @+ return { name: input.slice(0, atIndex) }
}
return { name: input }
}
modules/runtime/server/cache.ts (1)
222-238: Consider using parsePackageSpecifier to reduce code duplication.
This function contains inline parsing logic for extracting the package name and version specifier (lines 226-238) that duplicates the logic in parsePackageSpecifier. The same pattern appears in processSingleVersionsMeta (lines 300-312).
Since parsePackageSpecifier was introduced to centralise this parsing, consider refactoring these functions to use it for consistency and maintainability.
100-107: Consider adding a test case for undefined version.
The test covers null version but not undefined. Since the function signature accepts string | null | undefined, it would be good to explicitly test the undefined case for completeness.
I like that! ❤️ I just checked it out locally and jumping to the correct version by pressing enter is amazing.
The problem I see is I do not know about that functionality if I don't press enter and the search results do not indicate that this is even possible (because the package is not shown). Maybe a combination with stripping the version for the search as in #1626 could help so that the correct package will also be shown in the results?
…nstead of 404
Dependency links with version ranges (e.g. "^18.0.0 || ^19.0.0", ">15 <=16.0.2") previously
navigated to a non-existent version page and 404'd.
Now `packageRoute()` distinguishes exact versions from ranges: exact versions link to the version
page, while ranges link to the package page with `?semver=<range>#versions`, pre-populating the
existing "Filter by semver" input.
Closes#1120
Searching for `esbuild@0.25.12` or `@angular/core@^18` and pressing Enter now navigates directly to
the package version page (or semver filter for ranges) instead of returning no results.
Since in the previous commit I added support for linking to the package page with the a pre-filled
semver version specifier in the query string to populate the version filter, this supports both
exact versions and semver ranges in the search input.
Closes#1416

Clear the semver filter when ?semver= is removed.
The watcher at app/components/Package/Versions.vue:55-60 assigns semverFilter only when route.query.semver is a string. When the query is removed, the value is undefined, the assignment is skipped, and the previous filter stays active. The filter input keeps the old text and the version list stays filtered on the bare package URL. Set the value to an empty string in the else case:

Document the &semver= form for URLs that already have a query string.
The instruction applies ?semver= to "any package URL". When the URL already has a query string, the second ? becomes part of the previous parameter's value, so the version filter is not pre-populated. A reader who follows the instruction literally gets a URL that does not work.
