# @git.zone/tsrun
> Run TypeScript files instantly, without the compilation hassle ⚡
Execute TypeScript programs on-the-fly with zero configuration. Perfect for scripts, prototyping, and development workflows.
## 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.
## Installation
```bash
npm install -g @git.zone/tsrun
```
Or as a project dependency:
```bash
npm install --save-dev @git.zone/tsrun
```
## Usage
### 🚀 CLI Usage
Simply run any TypeScript file:
```bash
tsrun myScript.ts
```
Pass arguments to your script transparently:
```bash
tsrun myScript.ts --config production --verbose
```
All arguments are passed through to your TypeScript program, just as if you were running it with `node`.
### 💻 Programmatic API
Import tsrun in your code for dynamic TypeScript execution:
```typescript
import { runPath, runCli } from '@git.zone/tsrun';
// Run a TypeScript file from an absolute or relative path
await runPath('./scripts/myScript.ts');
// Run with path resolution relative to a file URL
await runPath('./myScript.ts', import.meta.url);
// Run in CLI mode programmatically (respects process.argv)
await runCli('./myScript.ts');
```
## Features
**Zero Configuration** - Just point and shoot. No tsconfig tweaking required.
**Fast Execution** - Powered by tsx for near-instant TypeScript execution.
🔄 **Transparent Arguments** - Command line arguments pass through seamlessly to your scripts.
📦 **Dual Interface** - Use as a CLI tool or import as a library in your code.
🎯 **TypeScript Native** - Full TypeScript support with excellent IntelliSense.
🔀 **Custom Working Directory** - Execute scripts with different cwds for parallel multi-project workflows.
## Why tsrun?
Sometimes you just want to run a TypeScript file without setting up a build pipeline, configuring webpack, or waiting for `tsc` to compile. That's where tsrun shines:
- **Quick Scripts**: Write and run TypeScript scripts as easily as bash scripts
- **Prototyping**: Test ideas without project setup overhead
- **Development Workflows**: Integrate TypeScript execution into your tooling
- **CI/CD**: Run TypeScript-based build scripts without pre-compilation
## Examples
### Simple Script
```typescript
// hello.ts
console.log('Hello from TypeScript! 🎉');
const greet = (name: string): string => {
return `Welcome, ${name}!`;
};
console.log(greet('Developer'));
```
Run it:
```bash
tsrun hello.ts
# Output:
# Hello from TypeScript! 🎉
# Welcome, Developer!
```
### With Command Line Arguments
```typescript
// deploy.ts
const environment = process.argv[2] || 'development';
const verbose = process.argv.includes('--verbose');
console.log(`Deploying to ${environment}...`);
if (verbose) {
console.log('Verbose mode enabled');
}
```
Run it:
```bash
tsrun deploy.ts production --verbose
# Output:
# Deploying to production...
# Verbose mode enabled
```
### Programmatic Execution
```typescript
// runner.ts
import { runPath } from '@git.zone/tsrun';
const scripts = [
'./scripts/setup.ts',
'./scripts/migrate.ts',
'./scripts/seed.ts'
];
for (const script of scripts) {
console.log(`Running ${script}...`);
await runPath(script, import.meta.url);
console.log(`✓ ${script} completed`);
}
```
### Running with Custom Working Directory
Execute TypeScript files with a different working directory using the `cwd` option. This is especially useful for parallel execution across multiple projects:
```typescript
import { runPath } from '@git.zone/tsrun';
// Run with custom cwd
await runPath('./build.ts', undefined, { cwd: '/path/to/project-a' });
// Parallel execution with different cwds (safe and isolated)
await Promise.all([
runPath('./deploy.ts', undefined, { cwd: '/projects/frontend' }),
runPath('./deploy.ts', undefined, { cwd: '/projects/backend' }),
runPath('./deploy.ts', undefined, { cwd: '/projects/api' })
]);
```
**How it works:**
- When `cwd` is provided, the script executes in a **child process** for complete isolation
- Without `cwd`, execution happens **in-process** (faster, less overhead)
- Child processes inherit all environment variables and stdio connections
- Perfect for running the same script across multiple project directories
**Notes:**
- Output from parallel executions may interleave on the console
- Each child process runs with its own isolated working directory
- Exit codes and signals are properly forwarded
