Project Structure

The snippets are organized in the src/ directory by category for easier maintenance:

• src/boilerplate.json - Full file templates
• src/cqrs.json - CQRS/MediatR patterns
• src/general.json - Basic C# constructs
• src/tests.json - Testing framework snippets
• src/web.json - ASP.NET Core snippets

Build Scripts

To combine all snippet files into the final snippets/csharp.json file used by Zed, run:

node src/combine.js

The src/combine.js script is used by these shell scripts to merge all category files into a single snippet file. Always run the combine script after making changes to any files in the src/ directory.
