Sample-2

Rhino Inside Node.js

The Rhino Inside® technology allows Rhino and Grasshopper to be embedded within other products.

Sample 2

This sample shows how to start Rhino from Node.js. This sample extends Sample 1 by showing how to define other functions that are exposed to Node.js via edge.js The sample has been tested on Windows 10, Rhino 7 WIP, and Node.js 8.11.12 (though should work on more recent versions of Node.js)

There are two projects:

• InsideNode.csproj - Compiles to a .net class library with one class and one method. This class contains the code to start Rhino.
• InsideNodeApp - Contains the Node.js code which calls the dotnet class library. Uses edge.js to call into dotnet.

Dependencies

• Rhino 7 WIP (Required install)
• RhinoInside NuGet (Referenced in the csproj)
• Node.js (8.11.2 or newer) (Required install)
• edge.js (^11.3.1) (Referenced via npm)

Running this sample

This assumes you've already installed Rhino 7 WIP and Node.js for Windows, and have cloned the Rhino.Inside repository.

1. Once you've cloned the Rhino.Inside repository, open the insideNode.sln in Visual Studio and build insideNode.csproj. This builds the .dll which is referenced in the Node.js project.
2. Open a console from the insideNodeApp directory.
3. Run npm install to install any dependencies.
4. Run node app.js to run the sample. In the terminal, you should see:

Rhino has started.
The mesh has 92 vertices and 100 faces.
