OptionalfetchOptions

fetchOptions?: Omit<RequestInit, "method" | "body">

Sets various request options on the fetch call made by an SDK method.

See

https://developer.mozilla.org/en-US/docs/Web/API/Request/Request#options|Request

OptionalfromResult

fromResult?: ((res?: Result) => Res)

fromResult allows you to provide a function to convert the generic Result type into another type

Example: Convert a response to boolean

Assuming that your policy evaluates to an object like {"allowed": true}, this fromResult function would let you convert it to a boolean:

const res = await new OPAClient(serverURL).evaluate<any, boolean>(
  "policy/result",
  { action: "read" },
  {
    fromResult: (r?: Result) => (r as Record<string, any>)["allowed"] ?? false,
  },
);

Optionalretries

retries?: RetryConfig

Set or override a retry policy on HTTP calls.

OptionalretryCodes

retryCodes?: string[]

Specifies the status codes which should be retried using the given retry policy.

OptionaltimeoutMs

timeoutMs?: number

Sets a timeout, in milliseconds, on HTTP requests made by an SDK method. If fetchOptions.signal is set then it will take precedence over this option.
