The Growing Risk of Malicious Browser Extensions
Socket researchers uncover how browser extensions in trusted stores are used to hijack sessions, redirect traffic, and manipulate user behavior.

Advanced tools
Buffered parallel processing of async iterables / generators.
import { bufferedAsyncMap } from 'buffered-async-iterable';
async function * asyncGenerator() {
yield ...
}
const mappedIterator = bufferedAsyncMap(asyncGenerator(), async (item) => {
// Apply additional async lookup / processing
});
for await (const item of mappedIterator) {
// Consume the buffered async iterable
}
import { bufferedAsyncMap } from 'buffered-async-iterable';
const mappedIterator = bufferedAsyncMap(['foo'], async (item) => {
// Apply additional async lookup / processing
});
for await (const item of mappedIterator) {

Iterates and applies the callback
to up to bufferSize
items from input
yielding values as they resolve.
bufferedAsyncMap(input, callback[, { bufferSize=6, ordered=false }]) => AsyncIterableIterator
input
โ either an async iterable, an ordinare iterable or an arraycallback(item)
โ should be either an async generator or an ordinary async function. Items from async generators are buffered in the main buffer and the buffer is refilled by the one that has least items in the current buffer (input
is considered equal to sub iterators in this regard when refilling the buffer)bufferSize
โ optional โ defaults to 6
, sets the max amount of simultanoeus items that processed at once in the buffer.ordered
โ optional โ defaults to false
, when true
the result will be returned in order instead of unorderedMerges all given (async) iterables in parallel, returning the values as they resolve
