anyEvent()
anyEvent():
AsyncIterableIterator
<[PropertyKey
,any
]>
Defined in: node_modules/.pnpm/emittery@1.1.0/node_modules/emittery/index.d.ts:562
Get an async iterator which buffers a tuple of an event name and data each time an event is emitted.
Call return()
on the iterator to remove the subscription.
In the same way as for events
, you can subscribe by using the for await
statement.
Returns
AsyncIterableIterator
<[PropertyKey
, any
]>
Example
import Emittery from 'emittery';
const emitter = new Emittery();
const iterator = emitter.anyEvent();
emitter.emit('🦄', '🌈1'); // Buffered
emitter.emit('🌟', '🌈2'); // Buffered
iterator.next()
.then(({value, done}) => {
// done is false
// value is ['🦄', '🌈1']
return iterator.next();
})
.then(({value, done}) => {
// done is false
// value is ['🌟', '🌈2']
// revoke subscription
return iterator.return();
})
.then(({done}) => {
// done is true
});

methods if methodNames
is not defined, into the target
object.
Parameters

clearListeners()
clearListeners<
Name
>(eventName?
):void
Defined in: node_modules/.pnpm/emittery@1.1.0/node_modules/emittery/index.d.ts:581
Clear all event listeners on the instance.
If eventName
is given, only the listeners for that event are cleared.
Type Parameters

Parameters

Returns

emit()
Call Signature
emit<
Name
>(eventName
):Promise
<void
>
Defined in: node_modules/.pnpm/emittery@1.1.0/node_modules/emittery/index.d.ts:496
Trigger an event asynchronously, optionally with some data. Listeners are called in the order they were added, but executed concurrently.
Type Parameters
Name
Name
extends DatalessEventNames
<Record
<PropertyKey
, any
>>
Parameters
eventName
Name
Returns
Promise
<void
>
A promise that resolves when all the event listeners are done. Done meaning executed if synchronous or resolved when an async/promise-returning function. You usually wouldn't want to wait for this, but you could for example catch possible errors. If any of the listeners throw/reject, the returned promise will be rejected with the error, but the other listeners will not be affected.

Defined in: node_modules/.pnpm/emittery@1.1.0/node_modules/emittery/index.d.ts:497

emitSerial()
Call Signature
emitSerial<
Name
>(eventName
):Promise
<void
>
Defined in: node_modules/.pnpm/emittery@1.1.0/node_modules/emittery/index.d.ts:509
Same as emit()
, but it waits for each listener to resolve before triggering the next one. This can be useful if your events depend on each other. Although ideally they should not. Prefer emit()
whenever possible.
If any of the listeners throw/reject, the returned promise will be rejected with the error and the remaining listeners will not be called.
Type Parameters
Name
Name
extends DatalessEventNames

Returns

Defined in: node_modules/.pnpm/emittery@1.1.0/node_modules/emittery/index.d.ts:510

events()

):AsyncIterableIterator
<Record

Defined in: node_modules/.pnpm/emittery@1.1.0/node_modules/emittery/index.d.ts:431
Get an async iterator which buffers data each time an event is emitted.
Call return()
on the iterator to remove the subscription.
Type Parameters
Name
Name

Parameters
eventName
Name
| readonly Name

Returns

Examples
import Emittery from 'emittery';
const emitter = new Emittery();
const iterator = emitter.events('🦄');
emitter.emit('🦄', '🌈1'); // Buffered
emitter.emit('🦄', '🌈2'); // Buffered
iterator
.next()
.then(({value, done}) => {
// done === false
// value === '🌈1'
return iterator.next();
})
.then(({value, done}) => {
// done === false
// value === '🌈2'
// Revoke subscription
return iterator.return();
})
.then(({done}) => {
// done === true
});
In practice you would usually consume the events using the for await statement. In that case, to revoke the subscription simply break the loop.
import Emittery from 'emittery';
const emitter = new Emittery();
const iterator = emitter.events('🦄');
emitter.emit('🦄', '🌈1'); // Buffered
emitter.emit('🦄', '🌈2'); // Buffered
// In an async context.
for await (const data of iterator) {
if (data === '🌈2') {
break; // Revoke the subscription when we see the value `🌈2`.
}
}
It accepts multiple event names.
import Emittery from 'emittery';
const emitter = new Emittery();
const iterator = emitter.events(['🦄', '🦊']);
emitter.emit('🦄', '🌈1'); // Buffered
emitter.emit('🦊', '🌈2'); // Buffered
iterator
.next()
.then(({value, done}) => {
// done === false
// value === '🌈1'
return iterator.next();
})
.then(({value, done}) => {
// done === false
// value === '🌈2'
// Revoke subscription
return iterator.return();
})
.then(({done}) => {
// done === true
