Implementation Plan for tsbuild check Command

Overview

Add a new check command to tsbuild that allows checking TypeScript files against a glob pattern without emitting them, similar to running the TypeScript compiler with the --noEmit flag.

Implementation Steps

1. Reread CLAUDE.md to ensure we follow project guidelines

2. Extend TsBuild Class

   • The existing TsBuild class already has a checkEmit() method
   • We can leverage this method for our implementation

3. Implement Check Command in CLI

   • Add a new check command to tsbuild.cli.ts
   • Command should accept glob patterns as arguments
   • Process glob patterns to find matching TypeScript files
   • Use the TsBuild class to check the files without emitting

4. Update Exports

   • Ensure any new functionality is properly exported

5. Testing

   • Test the command with various glob patterns
   • Verify error reporting works correctly

Differences from Existing emitcheck Command

The emitcheck command already exists and checks specific files without emitting. Our new check command will:

• Be designed specifically for checking files against glob patterns
• Use a simpler, more intuitive command name
• Potentially add additional benefits (like summary statistics of checked files)

Example Usage

Once implemented, the command would work like this:

npx tsbuild check ts/**/* 
npx tsbuild check "src/**/*.ts" "test/**/*.ts"

Expected Output

The command should:

• Report any TypeScript errors in the matched files
• Provide a count of files checked and any errors found
• Exit with code 0 if successful, or 1 if errors are found
