1. 概述

  本次 PR 新增 Angular 代码出码器(packages/frameworks/angular/projects/code-generator/),把 schema 转换为可编译的 Angular 单文件组件,并给 Angular 卡片增加了「导出源码」按钮。

2. 出码器是两个与物料、组件库无关的类

- CodeGeneratorBase —— 框架无关基类,提供 Vue 与 Angular 出码共用的方法;
- AngularCodeGenerator —— Angular 特定出码器,负责模板/状态/方法的生成与拼装。

3. 为什么需要组件库适配

AI 输出的 schema 与具体组件库(如 TinyNG)的组件名、属性、API 并不一一对应——例如 <ti-pagination> 的 total 是 totalNumber、srcData.state 需要归一化为对象、TiItem 的 label 需转成 <ti-item-label> 子元素。这些差异必须逐组件处理,否则产出的代码无法编译运行。
组件库适配不通过改动出码器本体完成,而是以「配置注入」的方式实现:每个组件库在 libraries/<library>/ 下提供一份 IAngularLibraryConfig(组件映射、prop 特判、库专属策略),注册到 AngularCodeGenerator.libraries 后即可出码。新增组件库(如未来的 Material)只需新增配置,无需改动两个类。

4. Playground 导出源码

给 Angular 生成的卡片增加了「导出源码」按钮,可将生成结果一键导出。

5. 说明

CodeGeneratorBase 是框架无关的类,抽取了 Vue 与 Angular 出码共用的方法,但本次提交仅在 Angular 出码时使用,未改动任何 Vue 侧代码。

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to d87d5

The Angular generator and source-export UI still have unresolved issues that can cause generated applications to fail, lose schema behavior or content, and make export unavailable to some users; the current head is not merge-ready until these correctness and accessibility problems are fixed or explicitly accepted.

115-119: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Report invalid schema JSON instead of returning an empty page.

normalizeIncomingSchema swallows a JSON.parse failure and returns { componentName: 'Page', children: [] }. AngularCodeGenerator.generate then produces an empty component and reports no error, because the errors array only collects unknown components. A malformed schema string therefore looks like a successful generation.

Record the parse failure so generate can add it to errors.

♻️ Proposed approach
-  protected normalizeIncomingSchema(origin: CardSchema | string | null | undefined): CardSchema {
+  protected schemaParseError: string | undefined;
+
+  protected normalizeIncomingSchema(origin: CardSchema | string | null | undefined): CardSchema {
+    this.schemaParseError = undefined;
     if (origin == null) {
       return { componentName: 'Page', children: [] } as CardSchema;
     }
     if (typeof origin === 'string') {
       const trimmed = origin.trim();
       if (!trimmed) {
         return { componentName: 'Page', children: [] } as CardSchema;
       }
       try {
         return JSON.parse(trimmed) as CardSchema;
-      } catch {
+      } catch (e) {
+        this.schemaParseError = `schema JSON 解析失败: ${(e as Error).message}`;
         return { componentName: 'Page', children: [] } as CardSchema;
       }
     }

Then push schemaParseError into compileErrors in generate.

Inline comments:
In `@packages/frameworks/angular/projects/code-generator-test/index.html`:
- Line 17: Replace the “Schema JSON” span with a label whose for association
targets the textarea identified by schema-input, ensuring the control has a
programmatic label without relying on placeholder text.

In `@packages/frameworks/angular/projects/code-generator-test/src/style.css`:
- Line 163: Replace the deprecated word-break: break-word declaration in the
style rule with the equivalent overflow-wrap declaration, preserving the
existing wrapping behavior.

In
`@packages/frameworks/angular/projects/code-generator/angular-code-generator.ts`:
- Line 120: Update the voidElements list used by generateTemplate to include
area, base, col, embed, meta, param, source, track, and wbr, preserving the
existing entries and ensuring these tags are emitted without closing tags.
- Around line 438-445: Update recurseChildren to handle single NodeSchema and
JSExpression object children before the string fallback, reusing the same
JSExpression rendering behavior as generateSlotTemplate. Generate template
output through generateTemplate for schema objects, and ensure object values are
never pushed directly into the string result array.
- Around line 567-571: Normalize the JSSlot value before mapping so a single
node object is wrapped as a one-element array while arrays remain unchanged.
Update the slotBody generation in the surrounding slot template logic to map
over this normalized array, preventing generate from failing on non-array
values.
- Around line 331-333: Update templateArgs construction alongside sigParams so
call arguments are generated positionally from the declared signature, providing
$event for the first declared parameter and preserving placeholders for any
additional declared parameters before freeVars and extendParams. Ensure a schema
function with multiple declared parameters receives each value in the matching
position.
- Around line 840-846: Normalize schema.state to a single empty-object fallback
before calling generateTemplate, then pass that same normalized object through
hoisting and state serialization. Update the generate flow and related state
handling around buildStateFields and generateTemplate so schemas without state
no longer pass undefined and hoisted properties are written to the serialized
state object.
- Around line 411-427: Update handleBinding to detect top-level JS_SLOT values
before the common literal/function/expression branches, transform the slot
wrapper, and pass the transformed value to hoistPropToTemplateField. Ensure the
transformation registers the ng-template and includes the
`#QUOTES_START`#this.slotN#QUOTES_END# placeholder expected by
buildLifecycleMethod.
- Line 888: Escape finalTemplate’s backslashes, backticks, and ${ sequences
before embedding it in the generated template literal, reusing the same approach
applied to schema.css. Ensure the escaped value is also used by
formatWithPrettier’s template extraction so backticks and ${ cannot terminate or
truncate the generated component template.

In
`@packages/frameworks/angular/projects/code-generator/libraries/tinyng/config.ts`:
- Line 60: Update the transformChildren logic for TiFormField so a single
NodeSchema is normalized to a one-element list before conversion, then restored
to its original single-node shape afterward. In the existing TiItem label
handling, preserve a one-node item.children value alongside labelNode instead of
replacing or discarding it; keep array and existing child-shape behavior
unchanged.

In `@packages/frameworks/angular/projects/code-generator/utils.ts`:
- Line 22: Update unwrapExpression so escaped carriage-return/newline sequences
are replaced with actual newline characters rather than removed, while
preserving the existing quote unescaping. Ensure generated multi-statement
bodies and line comments retain valid statement boundaries.

In `@packages/frameworks/angular/projects/renderer/package.json`:
- Line 40: Remove the direct prettier dependency from the renderer package
manifest and remove its corresponding entries from the lockfile, ensuring no
renderer dependency or lockfile reference remains solely for prettier. Leave
unrelated dependencies and package configuration unchanged.

In `@sites/playground/web/src/components/SchemaExportHeader.vue`:
- Around line 66-68: Update the Angular export button styles so the control is
visible and interactive under `@media` (hover: none) and whenever it matches
:focus-visible, overriding the default opacity, transform, and pointer-events
rules. Preserve the existing hover behavior for devices that support hover.

In `@sites/playground/web/src/hooks/use-generate-angular-code.ts`:
- Line 1: Remove the static generateCode import and dynamically import the
Angular generator inside exportAngularCode when export begins, awaiting the
module before invoking generateCode so Vite can split it into an export-time
chunk.

Associate the panel title with schema-input.

Schema JSON is rendered as a span, so the textarea has no programmatic label. Replace it with a label associated with id="schema-input" instead of relying on placeholder text.

The void-element list omits several HTML void elements.

voidElements lists only img, input, br, hr, link. area, base, col, embed, meta, param, source, track, and wbr are also void. generateTemplate (Line 704) therefore emits a closing tag for them, for example <track></track>, and the Angular template compiler rejects that. HTML_TAGS in constants.ts already accepts these tags, so a schema can reach this path.

Generated handler arguments misalign when the schema function declares two or more parameters.

sigParams starts with all declared parameters. templateArgs supplies one $event for the whole declared list. For a schema function (event, index) => {...} with one free variable row, the signature becomes __handle1(event?: any, index?: any, row?: any) but the template call is __handle1($event, row). row binds to index, and the row parameter stays undefined. The handler body then reads the wrong values.

Build the call arguments positionally from sigParams.

-      const sigParams = [...new Set([...declaredParams, ...freeVars, ...extendParams])];

Handle top-level JSSlot props before the common binding branches. resolvePropValueType returns JS_SLOT, but handleBinding has no JS_SLOT branch. The prop then emits no binding. Transform the wrapper itself before calling hoistPropToTemplateField; the transformed value must register the ng-template and contain the #QUOTES_START#this.slotN#QUOTES_END# placeholder consumed by buildLifecycleMethod.

Preserve every allowed child shape.

IAngularLibraryConfig.transformChildren accepts both NodeSchema[] and one NodeSchema. At Line 60, one direct TiFormField child skips the conversion. Its TiItem.label then bypasses the stated crash workaround. At Lines 77-78, one NodeSchema child of an existing TiItem is discarded when the label node replaces item.children.

Normalize a single NodeSchema into a list before transformation. Restore its original cardinality afterward. When item.children is one NodeSchema, retain it after labelNode.

Also applies to: 77-78

Deleting escaped newlines can join two statements into invalid code.

unwrapExpression receives JSON.stringify(...) output, so every real newline inside a hoisted function body or expression is the two-character escape \n. Line 22 deletes those escapes with no replacement. A body such as count = 1\nfoo() becomes count = 1foo() in the generated component, which does not compile. A // line comment in the body would also swallow the rest of the body.

Replace the escapes with a real newline instead of an empty string.

🐛 Proposed fix
 export const unwrapExpression = (value: string): string =>
   value.replace(new RegExp(`"${start}(.*?)${end}"`, 'g'), (match, p1) =>
-    p1.replace(/\\"/g, '"').replace(/\\r\\n|\\r|\\n/g, ''),
+    p1.replace(/\\"/g, '"').replace(/\\r\\n|\\r|\\n/g, '\n'),

Remove prettier from the renderer dependencies and lockfile. The renderer source does not import prettier or re-export code-generator, so the dependency is unnecessary for renderer consumers.

Keep the export control available without hover.

The Angular export button is transparent and has pointer-events: none until .angular-card-wrapper:hover applies. Touch devices do not provide hover, so users cannot activate the new export action. Keyboard users can also focus an invisible button.

Show the button for @media (hover: none) and when it has :focus-visible.

 .angular-card-wrapper:hover .schema-export-button {
   opacity: 1;
   transform: translateY(0);
   pointer-events: auto;

Load the Angular generator only when export starts.

Line 1 statically includes the generator in the initial playground bundle. Vue-only users must download and parse the Angular generator and its dependencies.

Move this import into exportAngularCode with await import(...). Vite can then split it into an export-time chunk.

Proposed fix
-import { generateCode } from '`@opentiny/genui-angular-code-generator`';
 
 export const useGenerateAngularCode = () => {
   const exportAngularCode = async (schema: string | object): Promise<void> => {
+    const { generateCode } = await import('`@opentiny/genui-angular-code-generator`');
     const result = await generateCode({ pageInfo: { schema: schema as never } });
