refactor: replace code generation with direct JSON interpretation
- Removed code generators (e2e/generators, storybook/generators) - Created JSON test runner that executes Playwright tests directly from JSON - Created JSON story loader that renders Storybook stories directly from JSON - No intermediate code generation - JSON is executable/renderable at runtime - json-packages.spec.ts auto-discovers and runs all package tests from JSON - DynamicStory component renders stories from JSON definitions - True meta/abstract architecture: configuration itself is executable - Single source of truth: JSON definitions only (no generated .spec.ts or .stories.tsx) - Changes to JSON take effect immediately without regeneration - Added comprehensive READMEs explaining the interpretation approach Co-authored-by: johndoe6345789 <224850594+johndoe6345789@users.noreply.github.com>

# E2E Test Generators
|
||||
|
||||
This folder contains tools for generating Playwright tests from declarative JSON definitions in packages.
|
||||
|
||||
## Structure
|
||||
|
||||
```
|
||||
e2e/
|
||||
├── generators/
|
||||
│ ├── playwright-generator.ts # Core generator logic
|
||||
│ └── generate.ts # CLI script
|
||||
├── generated/ # Generated .spec.ts files (gitignored)
|
||||
├── smoke.spec.ts # Manual smoke tests
|
||||
└── *.config.ts # Playwright configurations
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Generate All Package Tests
|
||||
|
||||
```bash
|
||||
# From project root
|
||||
npm run test:generate
|
||||
|
||||
# Or with watch mode
|
||||
npm run test:generate:watch
|
||||
```
|
||||
|
||||
### Generate Specific Package Tests
|
||||
|
||||
```bash
|
||||
npm run test:generate ui_home
|
||||
```
|
||||
|
||||
### Run Generated Tests
|
||||
|
||||
```bash
|
||||
npm run test:e2e -- e2e/generated/ui_home.spec.ts
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
1. **Discovery**: Scans `packages/*/playwright/tests.json` files
|
||||
2. **Parsing**: Reads JSON test definitions
|
||||
3. **Generation**: Converts to TypeScript `.spec.ts` files
|
||||
4. **Output**: Writes to `e2e/generated/`
|
||||
|
||||
## Package Test Definitions
|
||||
|
||||
Packages define tests in `playwright/tests.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"$schema": "https://metabuilder.dev/schemas/package-playwright.schema.json",
|
||||
"package": "ui_home",
|
||||
"tests": [
|
||||
{
|
||||
"name": "should load home page",
|
||||
"steps": [
|
||||
{ "action": "navigate", "url": "/" },
|
||||
{
|
||||
"action": "expect",
|
||||
"selector": "body",
|
||||
"assertion": { "matcher": "toBeVisible" }
|
||||
}
|
||||
]
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## Generated Output Example
|
||||
|
||||
```typescript
|
||||
/**
|
||||
* Auto-generated Playwright tests for ui_home package
|
||||
* Generated from: packages/ui_home/playwright/tests.json
|
||||
* DO NOT EDIT - This file is auto-generated
|
||||
*/
|
||||
|
||||
import { test, expect } from '@playwright/test'
|
||||
|
||||
test.describe('ui_home Package Tests', () => {
|
||||
test('should load home page', async ({ page }) => {
|
||||
await page.goto('/')
|
||||
await expect(page.locator('body')).toBeVisible()
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
## Benefits
|
||||
|
||||
- **Data-Driven**: Tests are JSON configuration, not code
|
||||
- **Package-Scoped**: Each package owns its test definitions
|
||||
- **Auto-Generated**: No manual TypeScript test writing
|
||||
- **Schema-Validated**: Tests conform to JSON schema
|
||||
- **Meta Architecture**: Tests themselves are declarative

# JSON Playwright Test Runner
|
||||
|
||||
**No code generation - tests are interpreted directly from JSON at runtime.**
|
||||
|
||||
This is the true meta/abstract approach: the JSON itself is executable, not just a template for code generation.
|
||||
|
||||
## Philosophy
|
||||
|
||||
Instead of generating `.spec.ts` files from JSON, we **directly execute** the JSON test definitions. This keeps tests as pure data that's interpreted at runtime, staying true to the 95% configuration rule.
|
||||
|
||||
## How It Works
|
||||
|
||||
1. **Discovery**: Scans `packages/*/playwright/tests.json` files
|
||||
2. **Loading**: Reads JSON test definitions at runtime
|
||||
3. **Interpretation**: Executes test steps directly from JSON
|
||||
4. **No Intermediate**: No code generation step - JSON → Execution
|
||||
|
||||
## Usage
|
||||
|
||||
### Run JSON-Defined Package Tests
|
||||
|
||||
```bash
|
||||
# Run all JSON-defined package tests
|
||||
npm run test:e2e:json
|
||||
|
||||
# Or run directly
|
||||
npm run test:e2e -- e2e/json-packages.spec.ts
|
||||
|
||||
# With UI mode
|
||||
npm run test:e2e:ui -- e2e/json-packages.spec.ts
|
||||
```
|
||||
|
||||
### How Tests Are Loaded
|
||||
|
||||
The `json-packages.spec.ts` file automatically discovers and loads all tests:
|
||||
|
||||
```typescript
|
||||
import { loadAllPackageTests } from './json-runner/playwright-json-runner'
|
||||
|
||||
// Discovers packages/*/playwright/tests.json and registers tests
|
||||
await loadAllPackageTests(packagesDir, test)
|
||||
```
|
||||
|
||||
## Example: JSON Test Definition
|
||||
|
||||
`packages/ui_home/playwright/tests.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"$schema": "https://metabuilder.dev/schemas/package-playwright.schema.json",
|
||||
"package": "ui_home",
|
||||
"tests": [{
|
||||
"name": "should display hero section",
|
||||
"tags": ["@smoke", "@ui"],
|
||||
"steps": [
|
||||
{
|
||||
"description": "Navigate to home page",
|
||||
"action": "navigate",
|
||||
"url": "/"
|
||||
},
|
||||
{
|
||||
"description": "Wait for page load",
|
||||
"action": "waitForLoadState",
|
||||
"state": "domcontentloaded"
|
||||
},
|
||||
{
|
||||
"description": "Verify hero title visible",
|
||||
"action": "expect",
|
||||
"selector": ".hero-title",
|
||||
"assertion": {
|
||||
"matcher": "toBeVisible"
|
||||
}
|
||||
}
|
||||
]
|
||||
}]
|
||||
}
|
||||
```
|
||||
|
||||
**Executed directly - no intermediate code generation!**
|
||||
|
||||
## Supported Actions
|
||||
|
||||
- **Navigation**: `navigate`, `waitForNavigation`, `waitForLoadState`
|
||||
- **Interactions**: `click`, `dblclick`, `fill`, `type`, `select`, `check`, `uncheck`, `hover`, `focus`, `press`
|
||||
- **Assertions**: `expect` with all Playwright matchers
|
||||
- **Utilities**: `wait`, `waitForSelector`, `screenshot`, `evaluate`
|
||||
|
||||
## Supported Selectors
|
||||
|
||||
- `selector` - CSS selector
|
||||
- `role` - ARIA role with optional text
|
||||
- `text` - Text content
|
||||
- `label` - Form label
|
||||
- `placeholder` - Input placeholder
|
||||
- `testId` - data-testid attribute
|
||||
|
||||
## Supported Assertion Matchers
|
||||
|
||||
All standard Playwright matchers:
|
||||
- Visibility: `toBeVisible`, `toBeHidden`
|
||||
- State: `toBeEnabled`, `toBeDisabled`, `toBeChecked`, `toBeFocused`, `toBeEmpty`
|
||||
- Content: `toHaveText`, `toContainText`, `toHaveValue`
|
||||
- Count: `toHaveCount`
|
||||
- Attributes: `toHaveAttribute`, `toHaveClass`, `toHaveCSS`
|
||||
- Page: `toHaveURL`, `toHaveTitle`
|
||||
|
||||
## Benefits of JSON Execution
|
||||
|
||||
1. **True Meta Architecture**: Tests are data, not code
|
||||
2. **No Build Step**: JSON is directly executable
|
||||
3. **Runtime Interpretation**: Changes take effect immediately
|
||||
4. **Single Source of Truth**: JSON is the only definition
|
||||
5. **Package Ownership**: Each package owns its test data
|
||||
6. **Schema Validated**: Tests conform to JSON schema
|
||||
|
||||
## File Structure
|
||||
|
||||
```
|
||||
e2e/
|
||||
├── json-runner/
|
||||
│ └── playwright-json-runner.ts # JSON test interpreter
|
||||
├── json-packages.spec.ts # Auto-loads all package tests
|
||||
└── smoke.spec.ts # Manual smoke tests
|
||||
```
|
||||
|
||||
## vs Code Generation
|
||||
|
||||
| Approach | Source of Truth | Runtime | Changes |
|
||||
|----------|----------------|---------|---------|
|
||||
| **Code Generation** | JSON → Generate `.spec.ts` | Executes TypeScript | Requires regeneration |
|
||||
| **JSON Execution** ✅ | JSON (only) | Interprets JSON | Immediate effect |
|
||||
|
||||
JSON execution is more meta/abstract - the configuration itself is executable!

# Storybook Story Generators
|
||||
|
||||
This folder contains tools for generating Storybook stories from declarative JSON definitions in packages.
|
||||
|
||||
## Structure
|
||||
|
||||
```
|
||||
storybook/
|
||||
├── generators/
|
||||
│ ├── storybook-generator.ts # Core generator logic
|
||||
│ └── generate.ts # CLI script
|
||||
├── generated/ # Generated .stories.tsx files (gitignored)
|
||||
└── .storybook/ # Storybook configuration
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Generate All Package Stories
|
||||
|
||||
```bash
|
||||
# From project root
|
||||
npm run storybook:generate
|
||||
|
||||
# Or with watch mode
|
||||
npm run storybook:generate:watch
|
||||
```
|
||||
|
||||
### Generate Specific Package Stories
|
||||
|
||||
```bash
|
||||
npm run storybook:generate ui_home
|
||||
```
|
||||
|
||||
### Run Storybook
|
||||
|
||||
```bash
|
||||
cd storybook
|
||||
npm run storybook
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
1. **Discovery**: Scans `packages/*/storybook/stories.json` files
|
||||
2. **Parsing**: Reads JSON story definitions
|
||||
3. **Generation**: Converts to TypeScript `.stories.tsx` files
|
||||
4. **Output**: Writes to `storybook/generated/`
|
||||
|
||||
## Package Story Definitions
|
||||
|
||||
Packages define stories in `storybook/stories.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"$schema": "https://metabuilder.dev/schemas/package-storybook.schema.json",
|
||||
"title": "Home Page Components",
|
||||
"stories": [
|
||||
{
|
||||
"name": "HomePage",
|
||||
"render": "home_page",
|
||||
"description": "Complete home page with all sections"
|
||||
},
|
||||
{
|
||||
"name": "HeroSection",
|
||||
"render": "hero_section",
|
||||
"args": {
|
||||
"title": "Build Anything, Visually"
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## Generated Output Example
|
||||
|
||||
```typescript
|
||||
/**
|
||||
* Auto-generated Storybook stories for ui_home package
|
||||
* Generated from: packages/ui_home/storybook/stories.json
|
||||
* DO NOT EDIT - This file is auto-generated
|
||||
*/
|
||||
|
||||
import type { Meta, StoryObj } from '@storybook/react'
|
||||
import { JSONComponentRenderer } from '@/components/JSONComponentRenderer'
|
||||
|
||||
const pkg = await loadJSONPackage(join(packagesDir, 'ui_home'))
|
||||
|
||||
const meta: Meta = {
|
||||
title: 'Home Page Components',
|
||||
}
|
||||
|
||||
export default meta
|
||||
type Story = StoryObj<typeof meta>
|
||||
|
||||
export const HomePage: Story = {
|
||||
name: 'HomePage',
|
||||
render: () => {
|
||||
const component = pkg.components?.find(c => c.id === 'home_page')
|
||||
return <JSONComponentRenderer component={component} allComponents={pkg.components} />
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
## Benefits
|
||||
|
||||
- **Data-Driven**: Stories are JSON configuration, not code
|
||||
- **Package-Scoped**: Each package owns its story definitions
|
||||
- **Auto-Generated**: No manual TypeScript story writing
|
||||
- **Schema-Validated**: Stories conform to JSON schema
|
||||
- **Meta Architecture**: Stories themselves are declarative

# JSON Storybook Story Loader
|
||||
|
||||
**No code generation - stories are loaded and rendered directly from JSON at runtime.**
|
||||
|
||||
This is the true meta/abstract approach: the JSON itself defines renderable stories, not templates for code generation.
|
||||
|
||||
## Philosophy
|
||||
|
||||
Instead of generating `.stories.tsx` files from JSON, we **directly load and render** the JSON story definitions. This keeps stories as pure data that's interpreted at runtime, staying true to the 95% configuration rule.
|
||||
|
||||
## How It Works
|
||||
|
||||
1. **Discovery**: Scans `packages/*/storybook/stories.json` files
|
||||
2. **Loading**: Reads JSON story definitions at runtime
|
||||
3. **Rendering**: Renders components directly from JSON via `DynamicStory` component
|
||||
4. **No Intermediate**: No code generation step - JSON → Render
|
||||
|
||||
## Usage
|
||||
|
||||
### Load Stories from JSON
|
||||
|
||||
```typescript
|
||||
import { loadAllStoryDefinitions } from './json-loader/storybook-json-loader'
|
||||
import { DynamicStory } from './json-loader/DynamicStory'
|
||||
|
||||
// Load all story definitions
|
||||
const storyDefs = await loadAllStoryDefinitions(packagesDir)
|
||||
|
||||
// Get a specific package's stories
|
||||
const uiHomeStories = storyDefs.get('ui_home')
|
||||
|
||||
// Render a story
|
||||
<DynamicStory
|
||||
packageName="ui_home"
|
||||
storyDef={uiHomeStories}
|
||||
story={uiHomeStories.stories[0]}
|
||||
packagesDir={packagesDir}
|
||||
/>
|
||||
```
|
||||
|
||||
### Example: JSON Story Definition
|
||||
|
||||
`packages/ui_home/storybook/stories.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"$schema": "https://metabuilder.dev/schemas/package-storybook.schema.json",
|
||||
"title": "Home Page Components",
|
||||
"category": "UI",
|
||||
"description": "Landing page components",
|
||||
"stories": [
|
||||
{
|
||||
"name": "HomePage",
|
||||
"render": "home_page",
|
||||
"description": "Complete home page with all sections"
|
||||
},
|
||||
{
|
||||
"name": "HeroSection",
|
||||
"render": "hero_section",
|
||||
"args": {
|
||||
"title": "Build Anything, Visually",
|
||||
"subtitle": "A 6-level meta-architecture"
|
||||
}
|
||||
}
|
||||
],
|
||||
"parameters": {
|
||||
"layout": "fullscreen"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Rendered directly - no intermediate code generation!**
|
||||
|
||||
## How Stories Are Rendered
|
||||
|
||||
1. `DynamicStory` component receives story definition
|
||||
2. Loads package components from `packages/{name}/components/ui.json`
|
||||
3. Finds component by `story.render` (matches component id or name)
|
||||
4. Passes `story.args` as props to `JSONComponentRenderer`
|
||||
5. Component renders from JSON definition
|
||||
|
||||
## Story Features
|
||||
|
||||
- **Args**: Pass props to components via `story.args`
|
||||
- **Parameters**: Configure Storybook display via `parameters`
|
||||
- **ArgTypes**: Define controls via `argTypes`
|
||||
- **Context Variants**: Multiple rendering contexts via `contextVariants`
|
||||
- **Default Context**: Shared context via `defaultContext`
|
||||
|
||||
## Benefits of JSON Loading
|
||||
|
||||
1. **True Meta Architecture**: Stories are data, not code
|
||||
2. **No Build Step**: JSON is directly loaded
|
||||
3. **Runtime Loading**: Changes take effect immediately
|
||||
4. **Single Source of Truth**: JSON is the only definition
|
||||
5. **Package Ownership**: Each package owns its story data

6. **Schema Validated**: Stories conform to JSON schema
|
||||
|
||||
## File Structure
|
||||
|
||||
```
|
||||
storybook/
|
||||
├── json-loader/
|
||||
│ ├── storybook-json-loader.ts # JSON story loader
|
||||
│ └── DynamicStory.tsx # Story renderer component
|
||||
└── .storybook/ # Storybook config
|
||||
```
|
||||
|
||||
## Integration with Storybook
|
||||
|
||||
Create a `.stories.tsx` file that uses the JSON loader:
|
||||
|
||||
```typescript
|
||||
// ui_home.stories.tsx
|
||||
import type { Meta, StoryObj } from '@storybook/react'
|
||||
import { loadStoryDefinition } from '../json-loader/storybook-json-loader'
|
||||
import { DynamicStory } from '../json-loader/DynamicStory'
|
||||
|
||||
const storyDef = await loadStoryDefinition('ui_home', packagesDir)
|
||||
|
||||
const meta: Meta = {
|
||||
title: storyDef.title,
|
||||
parameters: storyDef.parameters,
|
||||
}
|
||||
|
||||
export default meta
|
||||
|
||||
// Each story is rendered from JSON
|
||||
export const HomePage: StoryObj = {
|
||||
render: () => <DynamicStory
|
||||
packageName="ui_home"
|
||||
storyDef={storyDef}
|
||||
story={storyDef.stories[0]}
|
||||
packagesDir={packagesDir}
|
||||
/>
|
||||
}
|
||||
```
|
||||
|
||||
Or create a single loader file that auto-discovers all packages:
|
||||
|
||||
```typescript
|
||||
// all-packages.stories.tsx
|
||||
import { loadAllStoryDefinitions } from '../json-loader/storybook-json-loader'
|
||||
|
||||
const allStories = await loadAllStoryDefinitions(packagesDir)
|
||||
|
||||
// Generate stories for each package dynamically
|
||||
for (const [packageName, storyDef] of allStories) {
|
||||
// Register stories...
|
||||
}
|
||||
```
|
||||
|
||||
## vs Code Generation
|
||||
|
||||
| Approach | Source of Truth | Runtime | Changes |
|
||||
|----------|----------------|---------|---------|
|
||||
| **Code Generation** | JSON → Generate `.stories.tsx` | Renders React | Requires regeneration |
|
||||
| **JSON Loading** ✅ | JSON (only) | Loads & renders JSON | Immediate effect |
|
||||
|
||||
JSON loading is more meta/abstract - the configuration itself is renderable!
