Properties

Optional fetch

fetch?: {
    (input, init?): Promise<Response>;
    (input, init?): Promise<Response>;
}

Type declaration

Optional fetchOptions

fetchOptions?: Record<string, unknown>

Optional callOptions

callOptions?: Record<string, unknown>

Optional host

host?: string

Optional identity

identity?: types.Identity | Promise<types.Identity>

Optional ingressExpiryInMinutes

ingressExpiryInMinutes?: number

The maximum time a request can be delayed before being rejected.

Default

5 minutes

Optional credentials

credentials?: {
    name: string;
    password?: string;
}

Type declaration

  • name: string

agent.addTransform(makeNonceTransform(makeNonce);

Default

false

Optional retryTimes

retryTimes?: number

Number of times to retry requests before throwing an error

Default

3

Optional backoffStrategy

backoffStrategy?: BackoffStrategyFactory

The strategy to use for backoff when retrying requests

Optional verifyQuerySignatures

verifyQuerySignatures?: boolean

Whether the agent should verify signatures signed by node keys on query responses. Increases security, but adds overhead and must make a separate request to cache the node keys for the canister's subnet.

Default

true

Optional logToConsole

logToConsole?: boolean

Whether to log to the console. Defaults to false.

Optional rootKey

rootKey?: ArrayBuffer

Alternate root key to use for verifying certificates. If not provided, the default IC root key will be used.

Optional port

port?: number

Optional withLocalEnv

withLocalEnv?: boolean

Optional withDevtools

withDevtools?: boolean

Optional withProcessEnv

withProcessEnv?: boolean
