`shouldDisplay` +- Use **lowercase with dashes** for directory names: `src/core`, `src/interactive`, `__tests__/integration` +- Use **PascalCase** for classes and components: `TUIHandler`, `EffectCLI` +- Use **camelCase** for functions and variables: `displayJson`, `createPrompt`, `buildWorkflow` + +### Code Organization +- Structure files with exported main exports first, then subcomponents/helpers +- Use **modularization over code duplication** โ€” extract reusable logic into separate utility functions or modules +- Keep functions **single-responsibility** โ€” each function should do one thing well +- Use **JSDoc comments** for all exported functions and methods to improve IDE intellisense + +```typescript +/** + * Display a message with optional styling. + * +

+} + +// Less ideal: Deeply nested conditionals +if (input) { + if (input.length <= 100) { + // processing + } +} +``` + +### Functional Programming +- **Favor functional patterns** for utilities and helpers โ€” use pure functions +- **Use functional composition** with Effect's `.pipe()` for chaining operations +- **Avoid unnecessary state mutations** โ€” prefer immutable data structures +- **Classes are acceptable** for handler classes (`TUIHandler`, `EffectCLI`) as part of the intentional architecture + +### Documentation and Comments +- **Write clear JSDoc comments** for all exported functions, classes, and methods +- Include `@param`, `@returns`, and `@example` tags for complex functions +- Provide **concise comments for complex logic**, explaining the "why" not the "what" +- Keep comments up-to-date with code changes + +### Testing Standards +- **Write unit tests** for all utilities and public methods +- **Test error paths** using `Effect.catchTag()` to verify error

+**effect-cli-tui** is an Effect-native CLI framework designed for composable, type-safe command execution and interactive terminal interfaces. + +### Key Directories + +- **`src/`** โ€” Main source code + - `index.ts` โ€” Public API exports (all exports go here) + - `types.ts` โ€” Shared types and error definitions + - `cli.ts` โ€” `EffectCLI` class for running commands + - `tui.ts` โ€” `TUIHandler` class for interactive prompts + - `core/` โ€” Core display and styling utilities + - `tables/`, `boxes/`, `progress/` โ€” Feature modules + - `effects/` โ€” Ink/React wrapper for rich UIs + +- **`__tests__/`** โ€” Test suite (Vitest) + - Unit tests: `colors.test.ts`, `boxes.test.ts`, `tables.test.ts`, `spinners.test.ts` + - Integration: `integration.test.ts`, `integration/sm-cli-pattern.test.ts` + +- **`dist/`** โ€” Compiled output (ESM-only) + - `index.js` โ€” Main module + - `index.d.ts` โ€” TypeScript definitions + - `index.js.map` โ€” Source maps + +## Architecture Overview + +### Core Design Principles + +1. **Effect-First**: All public APIs return `Effect` for composable async operations and type-safe error handling +2. **Modular**: Clear separation between UI (`TUIHandler`), CLI execution (`EffectCLI`), and display utilities +3. **ESM-Only**: Modern JavaScript modules with tree-shaking support; built with tsup +4. **Type-Safe**: Strict TypeScript, typed errors using `Data.TaggedError` + +### Main Handler Classes + +**`EffectCLI`** (src/cli.ts) +- Executes CLI commands and captures output +- Methods: `run(command, args?, options?)`, `stream(command, args?, options?)` +- Returns: `Effect` +- Errors tagged as: `CLIError` with reasons like 'CommandFailed', 'Timeout', 'NotFound' + +**`TUIHandler`** (src/tui.ts) +- Interactive terminal UI with prompts +- Methods: `prompt()`, `selectOption()`, `multiSelect()`, `confirm()`, `display()` +- Returns: `Effect` +- Errors tagged as: `TUIError` with reasons like 'Cancelled', 'ValidationFailed', 'RenderError' + +### Display System Architecture + +Layered design: + +``` +Core Display (core/display.ts) + โ”œโ”€ display() โ†’ Single message effect + โ”œโ”€ displayLines() โ†’ Multiple lines + โ”œโ”€ displayJson() โ†’ Pretty JSON + โ””โ”€ displayOutput() โ†’ Internal formatter + +Styling Layer (core/colors.ts) + โ”œโ”€ applyChalkStyle() โ†’ Apply

โ”œโ”€ tables/table.ts โ†’ cli-table3 wrapper + โ”œโ”€ boxes/box.ts โ†’ Bordered box rendering + โ””โ”€ progress/spinner.ts โ†’ Spinner animation +``` + +### Error Handling Pattern + +All errors are typed using Effect's `Data.TaggedError`: + +```typescript +// Catch specific error tags +Effect.catchTag('TUIError', (err) => { + // Handle specific error +}) + +// Or use Error.as pattern for pattern matching +``` + +Error types in codebase: +- `TUIError` โ€” Interactive prompt failures +- `CLIError` โ€” Command execution failures + +### Validation with Effect Schema + +**Requirement:** All input validation must use **Effect Schema**, not Zod. + +Effect Schema provides: +- **Type-safe validation** with automatic TypeScript inference +- **Integration with Effect** โ€” validators return Effects natively +- **Composable schemas** โ€” build complex validators from simple ones +- **Consistent error handling** โ€” validation errors as Effect failures + +**Prefer Schema.Class over Schema.Struct:** +- โœ… Use `Schema.Class` for entity definitions (preferred) +- โš ๏ธ Use `Schema.Struct` only for anonymous/one-off structures +- Classes provide better type narrowing and IDE support +- Classes integrate seamlessly with Effect's service pattern + +**Basic Schema Example:** + +```typescript +import { Schema, Effect } from "effect" + +// Define a schema using Schema.Class (preferred pattern) +class User extends Schema.Class("User")({ + name: Schema.String.pipe(Schema.minLength(1)), + email: Schema.String.pipe(Schema.filter((email) => email.includes('@'))), + age: Schema.Number.pipe(Schema.greaterThan(0), Schema.lessThan(150)) +}) {} + +// Parse and validate +const validateUser = (input: unknown): Effect.Effect => { + return Schema.parse(User)(input) +} +``` + +**Validation in Prompts:** + +```typescript +import { Schema, Effect } from "effect" + +const projectNameSchema = Schema.String.pipe(Schema.minLength(3), Schema.maxLength(50)) + +const promptProject = Effect.gen(function* () { + const tui = yield* TUIHandler + + const name = yield* tui.prompt('Project name:', { + validate: (input) => { + try { + Schema.parseSync(projectNameSchema)(input) + return true + } catch (err) { + return 'Project name must be 3-50 characters' + } + } + }) + + return { projectName: name } +}) +``` + +**Error Handling:** + +```typescript +import { Schema, Effect } from "effect" + +class User extends Schema.Class("User")({ + name: Schema.String.pipe(Schema.minLength(1)), + email: Schema.String.pipe(Schema.filter((email) => email.includes('@'))), + age: Schema.Number.pipe(Schema.greaterThan(0), Schema.lessThan(150)) +}) {} + +// Validation errors are Effect failures +const workflow = Effect.gen(function* () { + const tui = yield* TUIHandler + + const result = yield* Schema.parse(User)(userData).pipe( + Effect.catchAll((err) => { + yield* tui.display(`Validation failed: ${err}`, 'error') + return Effect.fail(err) + }) + ) + return result +}) +``` + +**Use Effect Schema for:** +- โœ… CLI argument parsing and validation +- โœ… Configuration object validation +- โœ… User input validation in prompts +- โœ… Command output parsing and validation + +**Do NOT use Zod** โ€” Effect Schema is the standard validation library for this project. + +### ESM Output Configuration + +- Built with **tsup** (see `tsup.config.ts`) +- **ESM-only** format (no CommonJS output despite README examples) +- External deps: `effect`, `react`, `ink` (not bundled, peer-like) +- TypeScript declarations included with source maps +- Source maps included for debugging + +## Dependencies & Key Libraries + +**Production Dependencies:** +- `effect` ^3.18.0 โ€” Effect-TS runtime (core to architecture) +- `chalk` ^5.3.0 โ€” Terminal colors and styling +- `cli-table3`

Current implementation is ESM-only. + +## Testing Strategy + +**Test Framework:** Vitest 4.0.6 in Node.js environment + +**Test Organization:** +- Tests spy on `console.log` to verify output +- Integration tests compose Effect operations with `Effect.gen` +- Error handling tested via `Effect.catchTag()` +- Module import/export verification in dedicated test file + +**Running Tests:** +```bash +bun test # Run all once +bun test:watch # Watch mode +bun test -- --reporter=verbose # Detailed output +bun test __tests__/colors.test.ts # Single file +``` + +**Key Test Patterns:** +- Spy on console output for display functions +- Use `Effect.runPromise()` to execute Effects in tests +- Mock child_process for CLI tests +- Test error paths with `Effect.catchTag()` + +**Testing Effect.Service Services:** + +Do NOT use `new` to instantiate services in tests. Instead, use Effect dependency injection with mock layers: + +```typescript +import { Layer, Effect } from 'effect' +import { TUIHandler } from '../../src/tui' + +// Create a mock layer for testing +const MockTUIHandler = Layer.succeed(TUIHandler, { + display: (msg: string) => Effect.succeed(undefined), + prompt: (msg: string) => Effect.succeed('test-response'), + selectOption: (opts: string[]) => Effect.succeed(opts[0]), + multiSelect: (opts: string[]) => Effect.succeed(opts), + confirm: (msg: string) => Effect.succeed(true), + password: (msg: string) => Effect.succeed('test-password') +}) + +// Use the mock layer in tests +describe('TUIHandler', () => { + it('should display message', async () => { + const program = Effect.gen(function* () { + const tui = yield* TUIHandler // Access via dependency injection + yield* tui.display('Hello') + return 'success' + }).pipe(Effect.provide(MockTUIHandler)) // Provide the mock layer + + const result = await Effect.runPromise(program) + expect(result).toBe('success') + }) +}) +``` + +**Service Testing Rules:** +- โœ… Always use `yield* ServiceName` to access services, never `new ServiceName()` +- โœ… Create test layers with `Layer.succeed(ServiceName, {...})` +- โœ… Provide mock layers via `.pipe(Effect.provide(MockLayer))` +- โœ… Test services in isolation with full Effect composition +- โŒ NEVER try to instantiate services directly with `new` +- โŒ NEVER inject through constructor parameters + +**External Dependencies Testing Policy:** + +Do NOT mock external services (like CLI tools, HTTP services, databases). This codebase intentionally avoids mocking external dependencies because: + +1. **Integration Testing Over Unit Testing** โ€” Tests should verify actual behavior with real external systems +2. **No False Positives** โ€” Mocking can mask real failures that only appear with actual services +3. **Simplified Test Maintenance** โ€” No mock setup/teardown overhead +4. **Real-world Validation** โ€” Tests reflect production conditions + +**When external dependencies are unavailable:** +- โŒ Do NOT add `vi.mock()` or `vi.spyOn()` for external services +- โŒ Do NOT stub HTTP calls or CLI commands +- โœ… Skip the test gracefully with `.skip()` or test environment checks +- โœ… Document why the test requires the dependency (e.g., "requires pnpm global install") +- โœ… Let CI/integration environments handle full testing with dependencies installed + +**Example: Testing CLI commands** +```typescript +// โŒ WRONG - Don't mock child_process +it('should run command', async () => { + vi.spyOn(childProcess, 'execFile').mockImplementation(...) + // This masks real errors! +}) + +// โœ… RIGHT - Test with real CLI tool (or skip if unavailable) +it('should run command', async () => { + const result = await Effect.runPromise(cli.run('real-command')) + expect(result.success).toBe(true) +}) + +// โœ… ALSO RIGHT - Skip if dependency not installed +it('should run command if available', async () => { + const hasEffect = /* check if effect CLI installed */ + if (!hasEffect) this.skip() + + const result = await Effect.runPromise(cli.run('effect', ['--version'])) + expect(result.success).toBe(true) +}) +``` + +## Public API Exports + +All public APIs are exported from `src/index.ts`. When adding new functionality: + +1. Implement in appropriate `src/` module +2. Export from `src/index.ts` +3. Add tests in `__tests__/` +4. Update README.md if user-facing +5. Update docs/ if complex behavior + +**Current Exports:** +- Classes: `EffectCLI`, `TUIHandler` +- Display functions: `display`, `displayLines`, `displayJson`, `displaySuccess`, `displayError`, `displayOutput` +- Styling: `applyChalkStyle`, `displayHighlight`, `displayMuted`, `displayWarning`, `displayInfo`, `displayListItem` +- Components: `displayTable`, `displayBox`, `displayPanel` +- Progress: `spinnerEffect`, `startSpinner`, `updateSpinner`, `stopSpinner` +- React integration: `renderInkComponent`, `renderInkWithResult` +- Types: All from `src/types.ts` + +## Effect Service Pattern (Required) + +**All services must use Effect.Service API** (Effect 3.9+). This is the standard pattern for defining services with integrated Context.Tag and Layer. + +**Service Definition:** +```typescript +import * as Effect from 'effect/Effect' + +export class MyService extends Effect.Service()("app/MyService", { + effect: Effect.gen(function* () { + // Initialize dependencies if needed + // const dep = yield* SomeDependency + + return { + method1: (arg: string) => Effect.sync(() => { + // Implementation + }), + method2: () => Effect.sync(() => { + // Implementation + }) + } as const + }), + dependencies: [] // or [OtherService.Default] if needed +}) {} + +// Automatic Layer exports: +// MyService.Default โ€” with all dependencies provided +// MyService.DefaultWithoutDependencies โ€” if you need to override deps +``` + +**Service Usage:** +```typescript +const program = Effect.gen(function* () { + const service = yield* MyService + const result = yield* service.method1('arg') + return result +}).pipe(Effect.provide(MyService.Default)) +``` + +**Benefits:** +- โœ… Unified Context.Tag + Layer definition +- โœ… Proper dependency injection +- โœ… Testable with mock layers +- โœ… Works with Effect composition +- โœ… Modern Effect 3.9+ standard + +**FORBIDDEN - Do NOT use Context.Tag:** +- โŒ **NEVER** use `Context.GenericTag` or `Context.Tag` directly +- โŒ **NEVER** manually create Context.Tag + Layer separately +- โŒ Use plain classes with `new` keyword +- โŒ Pass services through constructor parameters + +**Why Context.Tag is Forbidden:** +Context.Tag is the old pre-3.9 pattern. It causes: +- Type inference issues with services +- Manual boilerplate code duplication +- Inconsistent error handling +- Harder to test with mocks +- Does not work with the modern Effect 3.9+ API + +Always use `Effect.Service` instead (see pattern above). + +--- + +## Common Development Patterns + +### Adding a New Display Function + +1. Create in appropriate module (`src/core/`, `src/tables/`, etc.) +2. Return `Effect` (or other appropriate type) +3. Use `effect()` from Effect library for async wrapping +4. Export from `src/index.ts` +5. Add test in `__tests__/` + +### Adding a New Handler Method + +1. Add to `TUIHandler` or `EffectCLI` class +2. Return `Effect` where ErrorType is the appropriate error +3. Use `Effect.tryPromise()` or `Effect.async()` to wrap async operations +4. Document error tags and return type +5. Add tests covering success and error paths + +### Error Handling in Features + +Always use `Data.TaggedError` for type-safe catching: + +```typescript +import { Data } from 'effect' + +export class MyError extends Data.TaggedError('MyError') { + readonly reason: 'Specific' | 'Reason' +} +``` + +Then consumers can catch specifically: +```typescript +.pipe(Effect.catchTag('MyError', handler)) +``` + +## TypeScript Configuration + +- **Target:** ES2020 +- **Module:** ESNext +- **Strict Mode:** Enabled +- **Declarations:** Generated with source maps +- **Module Resolution:** bundler (for tsup compatibility) + +Update `tsconfig.json` if changing target or module system. + +## Deployment & Publishing + +**Pre-publish Validation:** +```bash +bun run prepublishOnly # Runs: build && test +``` + +**Publishing Flow:** +1.
