|
|
|
> 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
