feat(workspace): merge package-manager workspace members into Nx discovery

[gbleu]

Fixes #70.

Problem

Nx infers projects from package.json scripts, so an Nx workspace's project set is a superset of its project.json files. Discovery only read project.json, so a package-only member was invisible: a change inside it marked nothing affected.

Solution

Merge the generic workspace loader's members into the Nx set. The merge itself is small; three things around it are needed to make it correct, and each fails silently when missing — you get a smaller affected set, never an error.

Negated workspace globs. workspaces::get_projects drops !packages/examples/** instead of applying it. Harmless in a plain workspace repo; merged into an Nx project set it pulls in packages the workspace deliberately excludes, which then report as affected. excluded_workspace_patterns applies them with the same match options as the positive patterns, so * stops at a separator on both sides and a one-level exclusion cannot swallow a nested member.

Nx metadata. Nx reads a package-only project's configuration from the nx key of its package.json; the generic loader does not. Without it a merged project arrives with no implicitDependencies — so a change to what it depends on never marks it affected — no sourceRoot, and no build-target tsConfig, which is how the resolver reaches a tsconfig.lib.json that no ancestor walk would find. The fields are read from a serde_json::Value rather than a typed manifest: tsConfig is a string or an array, as nx::deserialize_ts_config already handles for project.json, and a typed parse fails whole — one unexpected shape would discard the implicit dependencies and targets alongside it.

Workspace shapes the loader dropped: a workspace root with no name, and Yarn Classic's object form of workspaces.

Size

The diff is +489/−11, but two thirds of that is test coverage:

	lines
src/workspace/mod.rs — implementation	120
src/workspace/workspaces.rs — implementation	32
src/workspace/mod.rs — #[cfg(test)]	326
tests/integration_test.rs	11

Testing

Rebuilt on main (9332c1f) and verified standalone:

• cargo test --lib --no-default-features — 252 passed
• cargo test --no-default-features --test integration_test -- --test-threads=1 — 83 passed
• cargo fmt --all -- --check clean
• cargo clippy --all-targets --all-features — no warnings

Breaking changes

None. An Nx workspace whose members all have project.json discovers exactly the same project set as before.

📝 Walkthrough

Walkthrough

Package workspace parsing now supports unnamed roots and object-form workspace declarations. Nx discovery merges inferred workspace members with explicit projects, applies negated glob exclusions, and preserves selected package nx metadata. Tests cover these behaviors.

Changes

NX workspace discovery

Layer / File(s)	Summary
Workspace manifest parsing src/workspace/workspaces.rs	Workspace manifests support array and object forms. Workspace roots may omit name. Project construction still requires a package name.
Nx project merge and metadata src/workspace/mod.rs	Nx discovery adds eligible workspace members, removes duplicates, applies negated workspace patterns, and copies supported package.json nx metadata.
Discovery behavior validation src/workspace/mod.rs, tests/integration_test.rs	Tests cover workspace merging, exclusions, workspace formats, metadata preservation, and Nx detection precedence.

Merge Risk: 🟡 Moderate · up to 91d5e

Malformed workspace configuration can silently omit inferred projects, while duplicate workspace identities can produce ambiguous project results. Both should be fixed before merging.

Explanation

Issue #70 requires Nx discovery to find inferred projects. The PR adds package-manager workspace members, which covers package.json-inferred projects, and adds automated tests for merging and exclusion. However, the issue proposes the Nx project graph as the source for all project types, including plugin-inferred projects. The reviewed changes do not read .nx/workspace-data/project-graph.json. The PR summary also states that this change depends on #77 for workspace-relative roots and regresses when used alone.

Resolution

Make the #78 implementation work without the related PR, or include the required workspace-relative root behavior. Ensure discovery covers all Nx project types required by #70, including plugin-inferred projects, and add tests for the affected-project case.

Propagate workspace discovery failures.

workspaces::is_workspace(cwd) can detect a workspace before its configuration parses. If workspaces::get_projects(cwd) then returns an error, if let Ok discards it and discover_projects returns only the explicit Nx projects. The CLI treats that result as successful, so affected analysis can omit workspace projects.

-      if let Ok(ws_projects) = workspaces::get_projects(cwd) {
+      let ws_projects = workspaces::get_projects(cwd)?;

Update the deduplication sets for each merged project.

known_roots and known_names contain only the original Nx projects. If two workspace members have the same name, both pass this filter and both are appended. This violates the stated name-deduplication contract and can make downstream project lookup ambiguous.

Insert each accepted root and name into mutable sets before you append the project.

Proposed fix

-        projects.extend(
-          ws_projects
-            .into_iter()

Retracting my note above: #78 no longer needs #77.

#77's fix shipped upstream as 71788c3 (#87) on 27 Jul, so the regression that note warned about is fixed by the base branch itself. Rebuilt on main (9332c1f) standalone, this PR is green: 252 lib tests, 83 integration tests, cargo fmt --check clean, cargo clippy --all-targets --all-features with no warnings.

#77 is closed as superseded. This PR stands alone.
