Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.

Efficient structure representing a sequence of elements, with powerful operations for TypeScript
A Stream is an Iterable-like structure that represents a source that can stream values when requested. The source is unspecified, it may be a materialized object (e.g. an Array), or a calculated sequence (e.g. the fibonacci numbers). However, unlike an Iterable, a Stream offers many methods to change the values produced by the Stream, before it is consumed, without the need to materialize
intermediate instances.
This package exports the following main types:
Name | Description |
---|---|
FastIterable<T> | an Iterable that supports faster iterating than the Iterable type |
FastIterator<T> | an Iterator that supports faster iterating than the Iterator type |
Stream<T> | an Iterable-like structure that represents a source that can produce values of type T when requested |
Streamable<T> | an interface requiring that an object has a .stream() method |
StreamSource<T> | a convenience type that covers all types that can be automatically converted to a Stream |
For complete documentation please visit the Stream page in the Rimbu Docs.
Or Try Out Rimbu in CodeSandBox.
All types are exported through @rimbu/core
. It is recommended to use that package.
To install separately:
yarn add @rimbu/stream
or
npm i @rimbu/stream
Create a file called rimbu.ts
and add the following:
export * from 'https://deno.land/x/rimbu/stream/mod.ts';
Or using a pinned version (x.y.z
):
export * from 'https://deno.land/x/rimbu/stream@x.y.z/mod.ts';
Then import what you need from rimbu.ts
:
import { Stream } from './rimbu.ts';
Because Rimbu uses complex types, it's recommended to use the --no-check
flag (your editor should already have checked your code) and to specify a tsconfig.json
file with the settings described below.
Running your script then becomes:
deno run --no-check --config tsconfig.json <your-script>.ts
tsconfig.json
settingsRimbu uses advanced and recursive typing, potentially making the TypeScript compiler quite slow in some cases, or causing infinite recursion. It is recommended to set the following values in the tsconfig.json
file of your project:
{
"compilerOptions": {
"skipLibCheck": true,
"noStrictGenericChecks": true
}
}
import { Stream } from '@rimbu/stream';
console.log(Stream.range({ start: 10, amount: 15 }).toArray());
Feel very welcome to contribute to further improve Rimbu. Please read our Contributing guide.
