emit

Call Signature

emit<TEvent>(event): void

Emit an arc28 event log using either an ARC4Struct type or a named object type. Object types must have an ARC4 equivalent type.

Anonymous types cannot be used as the type name is used to determine the event prefix

TEvent extends Record<string, any>

TEvent

An ARC4Struct instance, or a plain object with a named type

void

class Demo extends Struct<{ a: Uint64 }> {}
emit(new Demo({ a: new Uint64(123) }))

type Demo = { a: uint64 }
emit<Demo>({a: 123})
// or
const d: Demo = { a: 123 }
emit(d)

emit<TProps>(eventName, …eventProps): void

Emit an arc28 event log using an explicit name and inferred property/field types. Property types must be ARC4 or have an ARC4 equivalent type.

TProps extends any[]

string

The name of the event (must be a compile time constant)

…TProps

A set of event properties (order is significant)

void

emit("Demo", new Uint64(123))

const a: uint64 = 123
emit("Demo", a)
