Functions

JsonChatCompletion

▸ JsonChatCompletion(«destructured», «destructured»): AsyncGenerator<string, string, unknown>

A ChatCompletion component that constrains the output to be a valid JSON string. It uses a combination of prompt engineering and validation with retries to ensure that the output is valid.

Though not required, you can provide a Zod schema to validate the output against. This is useful for ensuring that the output is of the expected type.

Example

const FamilyTree: z.Schema = z.array(
  z.object({
    name: z.string(),
    children: z.lazy(() => FamilyTree).optional(),
  })
);

const RootFamilyTree: z.ZodObject<any> = z.object({
  tree: FamilyTree,
});

return (
   <JsonChatCompletion schema={RootFamilyTree}>
    <UserMessage>
     Create a nested family tree with names and ages.
     It should include a total of 5 people.
    </UserMessage>
   </JsonChatCompletion>
);

Parameters

Name	Type
«destructured»	Omit<TypedObjectCompletionWithRetry, "typeName" | "parser" | "partialResultCleaner">
«destructured»	ComponentContext

Returns

AsyncGenerator<string, string, unknown>

A string that is a valid JSON or throws an error after retries attempts. Intermediate results that are valid, are also yielded.

YamlChatCompletion

▸ YamlChatCompletion(props, «destructured»): AsyncGenerator<string, string, unknown>

A ChatCompletion component that constrains the output to be a valid YAML string. It uses a combination of prompt engineering and validation with retries to ensure that the output is valid.

Though not required, you can provide a Zod schema to validate the output against. This is useful for ensuring that the output is of the expected type.

Example

const FamilyTree: z.Schema = z.array(
  z.object({
    name: z.string(),
    children: z.lazy(() => FamilyTree).optional(),
  })
);
const RootFamilyTree: z.ZodObject<any> = z.object({
  tree: FamilyTree,
});

return (
   <YamlChatCompletion schema={RootFamilyTree}>
    <UserMessage>
     Create a nested family tree with names and ages.
     It should include a total of 5 people.
    </UserMessage>
   </YamlChatCompletion>
);

Parameters

Name	Type
props	Omit<TypedObjectCompletionWithRetry, "typeName" | "parser">
«destructured»	ComponentContext

Returns

AsyncGenerator<string, string, unknown>

A string that is a valid YAML or throws an error after retries attempts. Intermediate results that are valid, are also yielded.
