How do I avoid consuming the response body in an AfterSuccess hook?

To avoid exhausting the response stream, you should always call response.clone() before reading the body, allowing the original stream to continue to the caller.

Where are the hooks registered in the SDK structure?

Hooks are typically registered in the src/hooks/registration.ts file (or the equivalent path for your specific language), which acts as the entry point for custom logic.

Which programming languages are supported for these SDK hooks?

This skill supports all major languages generated by Speakeasy, including TypeScript, Go, Python, Java, C#, Ruby, and PHP.

Does this skill overwrite my custom hooks when I regenerate the SDK?

No, custom hook files and the registration logic in registration.ts are specifically designed to be preserved and protected during the SDK regeneration process.

Can I use hooks to implement HMAC signing for my API?

Yes, HMAC signing is a primary use case. You can use the BeforeRequest hook to sign the request object with a secret before it is dispatched.

API 开发

Implements custom code logic and lifecycle hooks for Speakeasy-generated SDKs to handle telemetry, authentication, and request transformations.

The SDK Hook Customizer allows developers to inject custom business logic directly into the request-response lifecycle of Speakeasy-generated SDKs. By providing access to lifecycle events such as BeforeRequest and AfterSuccess, it enables the implementation of advanced features like HMAC signing, custom telemetry, and response transformations without losing changes during SDK regeneration. This skill ensures that your custom code is properly registered and maintained across updates, making it essential for building robust, production-grade API clients that require logic beyond standard OpenAPI specifications.
