Nuget package | CLI | Website | Try it online!

This library is the "core" where all the "magic" happens for translating/converting C# into JS, using Roslyn.

It is recommended to use the CLI/dotnet tool unless you want to write the front-end by yourself. Look for the implementation in the CLI, BWA app or the simple "Hello world" example below.

The CLI/dotnet tool is a simple cli front-end that behaves more or less like the dotnet cli, tsc cli, meson.

Hello world

Install the NuGet package or download a specific version.
Skip this if using a Nuget package. Follow the instructions on how to add a project reference.
In the Main method, add:

FileData file = new()
{
	SourceStr = @"Console.WriteLine(""Hello world."");"
};
file = CSTOJS.Translate(file);

Console.WriteLine(file.TranslatedStr);

Run a program
Console output should be:

console.log("Hello world.");

For options, look at the code or on the website.
To specify options (per file):

FileData file = new()
{
	OptionsForFile = new(){ Debug = true },
	...
};
