@stripe/extensibility-custom-objects-tools

Build-time transformer for Stripe custom objects.

Transforms TypeScript files containing @CustomObject decorators into platform-ready code with proxy-based change tracking, auto-save logic, and type-safe method dispatch.

CLI Usage

custom-objects-build --input src --output dist

Programmatic Usage

import { transform } from '@stripe/extensibility-custom-objects-tools';

const result = transform(sourceCode, 'my-file.ts');
// result.code     — transformed source code
// result.metadata  — extracted platform metadata
// result.errors    — any transformation errors

What It Does

• Extracts metadata from @CustomObject and @Action decorators
• Injects proxy wrapping in constructors for change tracking
• Adds auto-save logic to instance action methods
• Removes decorators from output (no runtime decorator overhead)
• Generates type-safe wrapper classes for method dispatch
