Angular: Hide class internals from the props table by default

[valentinpalkovic]

Closes #22007

What I did

An Angular props table documents the component's wiring next to its API. Injected services, backing fields and other class internals each get a row. On SAP's ui5-webcomponents-ngx that is 447 rows across 149 components, and every one is a private readonly … = inject(…) field.

This PR leaves out members that no template can reach. It adds one propsTable framework option to @storybook/angular-vite and deprecates features.angularFilterNonInputControls in favour of it. @storybook/angular (webpack) is not changed.

The ladder

propsTable has three values. Each one is a subset of the one above it, so two settings can never disagree.

Value	Sections	Members
all	properties, inputs, outputs, methods	every member
api	properties, inputs, outputs, methods	keeps every declared input and output; drops private and # properties and methods, and @internal members
inputs	inputs	the same member rule, narrowed to the inputs section

api is the default. It needs features.experimentalDocgenServer, because the frozen Compodoc pipeline encodes visibility only as raw TypeScript SyntaxKind numbers it does not interpret. With the Compodoc pipeline, which is still the default, only all and inputs apply and the props table does not change.

What counts as reachable

Two measured facts draw the line, not visibility keywords.

A component's own template cannot read a private member. A probe compiled with ngc 21.2.17, three components, each binding its own member, produced exactly one error, at every compiler setting:

src/app.ts:13:60 - error TS2341: Property 'privateField' is private and only accessible within class 'ProbePrivateComponent'.

A parent template, however, binds a private @Input() just fine, because Angular only honours access modifiers on input bindings behind the opt-in strictInputAccessModifiers flag - off even under strictTemplates - and never checks them on output bindings at all. From the shipped compiler (@angular/compiler-cli, strictTemplates branch of the type-checking config):

checkTypeOfInputBindings: strictTemplates,
honorAccessModifiersForInputBindings: false,
...
if (this.options.strictInputAccessModifiers !== void 0) {
  typeCheckingConfig.honorAccessModifiersForInputBindings = this.options.strictInputAccessModifiers;
}

So a private property or method is wiring, while a private input or output is API a consumer can bind. protected members stay for the same reason: the component's own template reads them (since Angular 14, and this framework's peer range is >=21.0.0 < 23.0.0). @internal drops a member not because templates cannot reach it - they can - but because the tag declares it non-API.

The decision that matters

One predicate, section-aware, and the only filtering layer in the pipeline:

// code/lib/angular-cm/src/extract-arg-types.ts
const documentedInMode = (item, section, propsTable) => {
  if (propsTable === 'all') {
    return true;
  }
  if (item.internal === true || item.name.startsWith('#')) {
    return false;
  }
  return section === 'inputs' || section === 'outputs' || item.visibility !== 'private';
};

The analyzer records visibility instead of acting on it, including for constructor parameter properties and undecorated non-public accessors, so all genuinely means every member (ES-# included). A model() and its synthesized ${name}Change output are documented or hidden as one unit, and the extractor logs why it left a member out (DEBUG=1). static members and lifecycle hooks are not filtered.

How the mode reaches each engine

        │                                              │
  docgen worker                                 client/compodoc.ts
        │                                       maps the mode to a per-call
  angular-cm extract-arg-types                  { filterNonInputControls } option
  (all three modes)                             on angular-compodoc/browser
                                                (all/inputs; api reads as all;
                                                 no define → FEATURES fallback)

viteFinal owns the warnings, not the docgen preset. Core only applies experimental_docgenProvider when experimentalDocgenServer is true, so a warning placed there would never fire in the one case it is about. The Compodoc adapter takes the filter as an argument on each call; @storybook/angular passes nothing and keeps reading the feature flag, unchanged.

One guard sits on the preview side. enhanceArgTypes is not a second-pass enhancer, so it still runs when the docgen server is on, and the UI unions the resulting customArgTypes back over the worker payload (mergeServiceArgTypes) - an unfiltered Compodoc extraction there resurrects every member api dropped. parameters.docs.extractArgTypes therefore contributes nothing under the flag (it stays defined, because the docs blocks read a missing extractor as "args unsupported"). A seam test traces that exact path - committed api payload, the parameter, the merge - and proves the private member stays out. Story arg passing is unaffected: cleanArgsDecorator passes everything through on empty argTypes and falls back to Angular's runtime input/output metadata otherwise.

Escape hatches

Set propsTable: 'all' to get today's behaviour back. To drop a single member the default keeps, tag it @ignore.

Deprecation

features.angularFilterNonInputControls still works on angular-vite and maps onto the ladder. Real output:

▲  The `angularFilterNonInputControls` feature is deprecated and will be
│  removed in Storybook 11. Replace it with the `propsTable: 'inputs'`
│  option on your `@storybook/angular-vite` framework.

Asking for api with the docgen server off warns rather than silently downgrading:

▲  `propsTable: 'api'` needs the `experimentalDocgenServer` feature,
│  which is off, so the props table keeps showing every member. Enable it
│  with `features: { experimentalDocgenServer: true }`, or set
│  `propsTable: 'all'` to say you want every member.

Measured on ui5-webcomponents-ngx

Ran the production buildDocgenPayload over the recorded community-eval clone under all and api, with the docgen server on.

Components	149, all resolved, 0 failures
Rows, all	1823
Rows, api	1376
Rows dropped	447
Distinct names dropped	3: cdr, elementRef, zone - 149 each
protected _cva surviving	16

The whole delta is those three names, which the generated dist/libs/ui5-angular/**/index.d.ts declares as private class fields - plain properties, not inputs - so the section-aware rule drops them identically. No input, output or public accessor is dropped, and the corpus contains no ES-# members that the widened all would surface. The 16 protected _cva members survive by design; @ignore is the tool for those.

This is not a regression users see today. On the same repo the Compodoc pipeline produced 628 rows and zero cdr / zone / elementRef / _cva rows, because ui5's components resolve from built .d.ts that Compodoc barely documents. The 447 rows are ones the docgen server introduces, so this PR keeps them from ever appearing rather than taking away rows people have.

Compodoc does document private fields in the ordinary source case, though - that is #22007. The committed fixture capture, taken with plain defaults, records private innerVolume with modifierKind: [123] (PrivateKeyword), and the legacy baseline renders it as a row.

Note on the number: the backlog entry says 596 noise rows. The measured figure is 447. 596 is 4 × 149, so the original count assumed a fourth per-component private field that this checkout does not have. The finding holds, only the number was high.

How the harness gates this

The comparator takes no allowlist. Each mode is held to the baseline that can legitimately judge it:

• extract('all') is gated against the unfiltered legacy Compodoc baseline - full parity, so the ladder can never hide a genuine extraction loss.
• extract('api') self-ratchets against its own committed acm-argtypes.snapshot with strict table checks, so any over-filtering regression fails as a named lost-arg before -u can persist it.
• extract('inputs') is additionally gated against the legacy inputs-only baseline.

The properties-methods-noise fixture (the #22007 origin case) now carries the members the rule is about: a private @Input() and private @Output() (kept), private/protected constructor parameter properties and accessors, an @internal member, and an ES-# field. Its compodoc-input.json was re-captured with the pinned Compodoc 2.0.0 staging flow, and the legacy baselines re-recorded from it.

Checklist for Contributors

Testing

The changes in this PR are covered in the following automated tests:

• stories
• unit tests
• integration tests
• end-to-end tests

Manual testing

1. Build the packages: yarn nx run-many -t compile -p angular-cm angular-compodoc angular-vite

2. Create a sandbox: yarn task sandbox --template angular-cli/default-ts --start-from auto

   That template ships @storybook/angular. Switch it to @storybook/angular-vite in .storybook/main.ts before you continue, or use any local Angular project already on angular-vite.

3. Turn the docgen server on in .storybook/main.ts, because 'api' needs it:

   features: { experimentalDocgenServer: true },

4. Add these members to a component that has a story, for example src/stories/button.component.ts:

   import { ChangeDetectorRef, inject } from '@angular/core';
   
   private readonly cdr = inject(ChangeDetectorRef);
   protected helperLabel = 'Next page';
   @Input() private density = 'compact';
   /** @internal */
   buildId = 'noise-1';

5. Run Storybook and open that component's Docs page.

6. Expect the props table to show helperLabel and density, and not cdr or buildId.

7. Add propsTable: 'all' to framework.options and restart. Expect cdr and buildId back.

8. Replace it with features: { angularFilterNonInputControls: true } and restart. Expect the inputs section only (density included), plus this warning in the terminal:

   ▲  The `angularFilterNonInputControls` feature is deprecated and will be
   │  removed in Storybook 11. Replace it with the `propsTable: 'inputs'`
   │  option on your `@storybook/angular-vite` framework.
   

9. Set features: { experimentalDocgenServer: false } together with propsTable: 'api'. Expect the experimentalDocgenServer warning above, and every member back in the table.

10. Repeat steps 4 to 6 on a @storybook/angular (webpack) sandbox. Expect no change and no warning.

Add a case for a defined STORYBOOK_ANGULAR_OPTIONS without propsTable.

The guard in code/frameworks/angular-vite/src/client/compodoc.ts at lines 20-21 has two branches that both yield undefined. This file covers only the missing-define branch. A user on an older main.ts has STORYBOOK_ANGULAR_OPTIONS defined with no propsTable, and that path must also fall back to the deprecated feature.

Remove test-comparison history from this comment.

Lines 4-5 describe the coverage of other tests. Keep only the seam rationale and the required behavior.

Proposed comment update

-// The docgen-server render path for the props table: the worker payload is filtered by
-// `propsTable`, but the UI unions the client-side `customArgTypes` back on top of it
-// (`mergeServiceArgTypes`), and `customArgTypes` is fed by `parameters.docs.extractArgTypes`.
-// Every other test stops at `extractArgTypesFromData`; this one gates the seam where an unfiltered
-// Compodoc extraction would resurrect the filtered members in the rendered table.
+// Keep Compodoc extraction annotation-only when docgen-server provides `payload.argTypes`.
+// This prevents filtered members from returning through `customArgTypes`.

Use memfs for fixture reads.

Mock node:fs with vi.mock('node:fs', { spy: true }). In beforeEach, reset and seed vol, redirect vi.mocked(readFileSync) to memfs.readFileSync, and load both fixtures before calling setCompodocJson. Move the current top-level fixture reads into this setup.
