Node.js	✅	Through the schema option
Go	☑️	Not required. Inferred via Reflection
.Net	☑️	Not required. Inferred via Reflection

Node.js

schema is only applicable to languages where the SDK cannot reflect the function type at runtime. NodeJS require the schema to be specified, however Go and .Net do not.

In Node.js, a zod schema that defines the input shape of the function. The schema is used to explain how to use the function, and to validate the input before the function is executed.

​

Handler

Go	✅
.Net	✅

​

Config object

Additional configuration options for the function.

Retry Count on Stall

Language	Supported	Option
Node.js	✅	config.retryCountOnStall
Go	❌
.Net	❌

The number of times Inferable will retry the function call if the function stalls.

A function can stall if it does not complete within the allotted time. This usually happens if:

• Function fails to complete within the allotted timeoutSeconds time.
• Worker stalls due to a machine crash or network problems. (See Recovering from machine failures for more information)

Without this configuration, Inferable will not retry the function call.

timeoutSeconds

Language	Supported	Option
Node.js	✅	config.timeoutSeconds
Go	❌
.Net	❌

The number of seconds Inferable will wait before timing out the function call.

cache

Language	Supported	Option
Node.js	✅	config.cache
Go	❌
.Net	❌

Used to cache the result of the function for a specified amount of time.

• ttl - The time in milliseconds that the result of the function will be cached.
• keyPath - The path (described using JSONPath) to the unique identifier in the function’s input.

private

Language	Supported	Option
Node.js	✅	config.private
Go	❌
.Net	❌

When set to true, the function will not be made available to the agent. This is can be used for functions registered as onStatusChange handlers.
