@rimbu/stream

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:

For complete documentation please visit the Stream page in the Rimbu Docs, or directly see the Rimbu Stream API Docs.

Or Try Out Rimbu in CodeSandBox.

• Node >= 16
• Deno
• Bun >= 0.6.0
• Web

For convenience, all main types are also exported through @rimbu/core.

To install this package only:

For yarn:

yarn add @rimbu/stream

For npm:

npm i @rimbu/stream

For bun:

bun add @rimbu/stream

For Deno, the following approach is recommended:

In the root folder of your project, create or edit a file called import_map.json with the following contents (where you should replace x.y.z with the desired version of Rimbu):

{
  "imports": {
    "@rimbu/": "https://deno.land/x/rimbu@x.y.z/"
  }
}

Note: The trailing slashes are important!

In this way you can use relative imports from Rimbu in your code, like so:

import { List } from '@rimbu/core/mod.ts';
import { HashMap } from '@rimbu/hashed/mod.ts';

Note that for sub-packages, due to conversion limitations it is needed to import the index.ts instead of mod.ts, like so:

import { HashMap } from '@rimbu/hashed/map/index.ts';

To run your script (let's assume the entry point is in src/main.ts):

deno run --import-map import_map.json src/main.ts

import { Stream } from '@rimbu/stream';

console.log(Stream.range({ start: 10, amount: 15 }).toArray());
