# DenoHost
---
## About
**DenoHost** allows you to seamlessly run [Deno](https://deno.com/) scripts or
inline JavaScript/TypeScript code within your .NET applications.\
It bundles platform-specific Deno executables as separate NuGet packages and
provides a simple, consistent API for execution.
---
## Features
- Modular runtime packages (per RID)
- Clean .NET API with async execution
- Testable with xUnit
- Packaged for NuGet (multi-target)
- Linux, Windows, macOS support
---
## NuGet Packages
```bash
dotnet add package DenoHost.Core
```
| Package | Description | Platforms |
| ------------------------------ | ---------------------------- | ------------- |
| `DenoHost.Core` | Core execution logic (API) | all |
| `DenoHost.Runtime.win-x64` | Bundled Deno for Windows | `win-x64` |
| `DenoHost.Runtime.win-arm64` | Bundled Deno for Windows ARM | `win-arm64` |
| `DenoHost.Runtime.linux-x64` | Deno for Linux | `linux-x64` |
| `DenoHost.Runtime.linux-arm64` | Deno for ARM Linux | `linux-arm64` |
| `DenoHost.Runtime.osx-x64` | Deno for macOS Intel | `osx-x64` |
| `DenoHost.Runtime.osx-arm64` | Deno for macOS Apple Silicon | `osx-arm64` |

## Deno.Execute Example
For simple script execution with immediate results:
```csharp
using DenoHost.Core;
var options = new DenoExecuteBaseOptions { WorkingDirectory = "./scripts" };
string[] args = ["run", "app.ts"];
await Deno.Execute(options, args);
```
### Cancellation
You can cancel execution via a `CancellationToken`. Cancellation throws an `OperationCanceledException` and terminates the underlying Deno process.
```csharp
using DenoHost.Core;
using var cts = new CancellationTokenSource(TimeSpan.FromSeconds(10));
var options = new DenoExecuteBaseOptions { WorkingDirectory = "./scripts" };
await Deno.Execute(options, ["run", "long-running.ts"], cts.Token);
```
### Arguments and quoting
DenoHost passes arguments via `ProcessStartInfo.ArgumentList`. Pass each argument as its own string (avoid adding shell-style quotes inside argument strings).
```csharp
await Deno.Execute("eval", ["console.log('hello world')"]);
```
## DenoProcess Example
For long-running processes with interactive communication:
```csharp
using DenoHost.Core;
// Create a managed Deno process
using var denoProcess = new DenoProcess(
command: "run",
args: ["--allow-read", "server.ts"],
workingDirectory: "./scripts"
);
// Start the process
await denoProcess.StartAsync();
// Send input to the process
await denoProcess.SendInputAsync("hello");
// Stop gracefully when done
await denoProcess.StopAsync();
```
## Requirements
- .NET 9.0+
- Deno version is bundled per RID via GitHub Releases
- No need to install Deno globally
## Feedback
If you're using DenoHost in a real project, I'd love to hear about it.
