 # Changelog
 
+## 2025-10-17 - 1.6.0 - feat(core)
+Add spawnPath child-process API with timeout/abort/terminate support, export native types, and expand README
+
+- Implement spawnPath(filePath, fromFileUrl?, options?) in ts/index.ts producing an ITsrunChildProcess with childProcess, stdout, stderr, exitCode, kill() and terminate()
+- Introduce ISpawnOptions (cwd, env, args, stdio, timeout, signal) and ITsrunChildProcess interfaces for robust process control
+- Handle timeouts (auto SIGTERM), AbortSignal cancellation, and graceful terminate() (SIGTERM then SIGKILL after 5s)
+- Export Node types ChildProcess and Readable from ts/plugins.ts for improved typings
+- Greatly expand README: add badges, table of contents, detailed API docs and examples for runPath, runCli and spawnPath, and troubleshooting guidance
+- Add local .claude/settings.local.json (environment/settings file)
+
 ## 2025-10-16 - 1.5.0 - feat(core)
 Add cwd option and child-process execution for custom working directory; implement signal-forwarding child runner; update docs and bump package version to 1.4.0

 ## What is tsrun?
 
 **tsrun** is a lightweight TypeScript execution tool that lets you run `.ts` files directly—no build step required. It's like running JavaScript with `node`, but for TypeScript. Under the hood, tsrun uses [tsx](https://github.com/esbuild-kit/tsx) for lightning-fast execution while keeping your workflow simple and efficient.

 ### 💻 Programmatic API
 
-Import tsrun in your code for dynamic TypeScript execution:
+tsrun provides three powerful functions for different execution needs:
+
+#### runPath() - Simple Execution
+
+Wait for a script to complete. Perfect for sequential workflows.
 
 ```typescript
-import { runPath, runCli } from '@git.zone/tsrun';
+import { runPath } from '@git.zone/tsrun';
 
-// Run a TypeScript file from an absolute or relative path
-await runPath('./scripts/myScript.ts');
+// Run a TypeScript file (absolute or relative path)
+await runPath('./scripts/build.ts');
 
-// Run with path resolution relative to a file URL
-await runPath('./myScript.ts', import.meta.url);
+// With path resolution relative to a file URL
+await runPath('./build.ts', import.meta.url);
 
-// Run in CLI mode programmatically (respects process.argv)
-await runCli('./myScript.ts');
+// With custom working directory
+await runPath('./build.ts', import.meta.url, { cwd: '/path/to/project' });
+```
+
+#### runCli() - CLI Mode
+
+Run with process.argv integration, as if invoked from command line.
+
+```typescript
+import { runCli } from '@git.zone/tsrun';
+
+// Respects process.argv for argument passing
+await runCli('./script.ts');
+```
+
+#### spawnPath() - Advanced Control
+
+Full process control with stdio access, timeouts, and cancellation.
+
+```typescript
+import { spawnPath } from '@git.zone/tsrun';
+
+// Returns immediately with process handle
+const proc = spawnPath('./task.ts', import.meta.url, {
+  timeout: 30000,
+  cwd: '/path/to/project',
+  env: { NODE_ENV: 'production' },
+  args: ['--verbose']
+});
+
+// Access stdout/stderr streams
+proc.stdout?.on('data', (chunk) => console.log(chunk.toString()));
+
+// Wait for completion

+
+### Development Scripts
+
+```typescript

+import { runPath } from '@git.zone/tsrun';
+
+console.log('Setting up development environment...');
+await runPath('./install-deps.ts', import.meta.url);

+## API Reference
+
+Choose the right function for your use case:
+
+| Function | Use When | Returns | Execution Mode |
+|----------|----------|---------|----------------|
+| `runPath()` | Simple script execution, sequential workflows | Promise (waits) | In-process (or child with cwd) |
+| `runCli()` | Need process.argv integration | Promise (waits) | In-process |
+| `spawnPath()` | Need process control, stdio access, timeout/cancel | Process handle | Child process |
+
+**Quick decision guide:**
+- 🎯 **Need to wait for completion?** → Use `runPath()` or `runCli()`
+- 🎛️ **Need to capture output or control process?** → Use `spawnPath()`
+- ⚡ **Running multiple scripts in parallel?** → Use `runPath()` with custom `cwd` or `spawnPath()`
+- ⏱️ **Need timeout or cancellation?** → Use `spawnPath()`

+### Advanced Process Control with spawnPath()
+
+For advanced use cases requiring full process control, stdio access, or timeout/cancellation support, use `spawnPath()`. Unlike `runPath()` which waits for completion, `spawnPath()` returns immediately with a process handle.
+
+```typescript
+import { spawnPath } from '@git.zone/tsrun';
+
+// Basic spawning with output capture
+const proc = spawnPath('./build.ts', import.meta.url);
+
+proc.stdout?.on('data', (chunk) => {
+  console.log('Output:', chunk.toString());
+});
+
+proc.stderr?.on('data', (chunk) => {
+  console.error('Error:', chunk.toString());
+});
+
+const exitCode = await proc.exitCode;
+console.log(`Process exited with code ${exitCode}`);
+```
+
+**With timeout and custom environment:**
+
+```typescript
+const proc = spawnPath('./long-running-task.ts', import.meta.url, {
+  timeout: 30000,  // Kill after 30 seconds
+  cwd: '/path/to/project',
+  env: {
+    NODE_ENV: 'production',
+    API_KEY: 'secret'
+  },
+  args: ['--mode', 'fast']
+});
+
+try {
+  const exitCode = await proc.exitCode;
+  console.log('Task completed:', exitCode);
+} catch (error) {
+  console.error('Task failed or timed out:', error.message);
+}
+```
+
+**AbortController integration:**
+
+```typescript
+const controller = new AbortController();
+const proc = spawnPath('./task.ts', import.meta.url, {
+  signal: controller.signal
+});
+
+// Cancel after 5 seconds
+setTimeout(() => controller.abort(), 5000);
+
+try {
+  await proc.exitCode;
+} catch (error) {
+  console.log('Process was aborted');
+}
+```
+
+**Graceful termination:**
+
+```typescript
+const proc = spawnPath('./server.ts', import.meta.url);
+
+// Later: gracefully shut down
+// Sends SIGTERM, waits 5s, then SIGKILL if still running
+await proc.terminate();
+```
+
+**Key differences from runPath():**
+
+| Feature | runPath() | spawnPath() |
+|---------|-----------|-------------|
+| Returns | Promise (waits) | Process handle (immediate) |
+| Default execution | In-process (unless cwd) | Always child process |
+| stdio | 'inherit' (transparent) | 'pipe' (capturable) |
+| Process control | Limited | Full (streams, signals, timeout) |
+| Use case | Simple script execution | Complex process management |

+## Troubleshooting
+
+### Common Issues
+
+**"Cannot find module" errors**
+
+Make sure you're using absolute paths or paths relative to `import.meta.url`:
+
+```typescript
+// ❌ Wrong - relative to cwd
+await runPath('./script.ts');
+
+// ✅ Correct - relative to current file
+await runPath('./script.ts', import.meta.url);
+```
+
+**Process hangs or doesn't complete**
+
+When using `spawnPath()`, make sure to await the `exitCode` promise:
+
+```typescript
+const proc = spawnPath('./script.ts', import.meta.url);
+// Don't forget to await!
+await proc.exitCode;
+```
+
+**Timeout not working**
+
+Timeouts only work with `spawnPath()`, not with `runPath()`:
+
+```typescript
+// ❌ Wrong - timeout is ignored
+await runPath('./script.ts', import.meta.url, { timeout: 5000 });
+
+// ✅ Correct - use spawnPath for timeout support
+const proc = spawnPath('./script.ts', import.meta.url, { timeout: 5000 });
+await proc.exitCode;
+```
+
+**Environment variables not available**
+
+The `env` option automatically merges with `process.env` - your custom values override parent values:
+
+```typescript
+// Parent env is automatically inherited
+spawnPath('./script.ts', import.meta.url, {
+  env: {
+    CUSTOM_VAR: 'value'  // Added to parent env
+  }
+});
+
+// Script will see both process.env AND CUSTOM_VAR
+```
