@rimbu/core

This package exports all the Rimbu collections, plus the contents of the @rimbu/common package. Its aim is to provide an easy to use access point for the collections.

For complete documentation please visit the Rimbu Docs.

Or Try Out Rimbu in CodeSandBox.

Installation

To get started with the immutable collections, which are exported through @rimbu/core, you can use the following.

Yarn/NPM

For yarn:

yarn add @rimbu/core

For npm:

npm i @rimbu/core

Deno

Create a file called rimbu.ts and add the following:

export * from 'https://deno.land/x/rimbu/core/mod.ts';

Or using a pinned version (x.y.z):

export * from 'https://deno.land/x/rimbu/core@x.y.z/mod.ts';

Then import what you need from rimbu.ts:

import { HashMap } 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

Usage

Using direct imports:

import { List, Stream, SortedMap } from '@rimbu/core';

const list = List.of(1, 3, 2, 4, 2);

const stream = Stream.from(list).map((v) => [v, String(v * 2)]);

const map = SortedMap.from(stream);

console.log(map.toArray());
// => [[1, '2'], [2, '4'], [3, '6'], [4, '8']]

The same code using the Create menu-object:

import Rimbu from '@rimbu/core';

const list = Rimbu.Create.List.of(1, 3, 2, 4, 2);

const stream = Rimbu.Create.Stream.from(list).map((v) => [v, String(v * 2)]);

const map = Rimbu.Create.Map.Sorted.from(stream);

console.log(map.toArray());
// => [[1, '2'], [2, '4'], [3, '6'], [4, '8']]

Contents

This package exports everything from the following packages:

Name	Description
@rimbu/bimap	a bidirectional map in which keys and values have a one-to-one mapping
@rimbu/bimultimap	a bidirectional multimap in which keys and values have a many-to-many mapping
@rimbu/collection-types	definitions for many of the generic collection types, used to derive more specific implementations
@rimbu/common	contains public types and functions that are used throughout the whole library
@rimbu/deep	offers tools to use handle plain JS objects as immutable objects. library
@rimbu/graph	provides various graph implementations to represent data in forms of nodes and edges
@rimbu/hashed	provides a HashMap and HashSet implementation, using hash functions to efficiently retrieve keys
@rimbu/list	provides the List datastructure containing an ordered sequence of elements that can be manipulated and accessed randomly in an efficient way
@rimbu/multimap	provides a map in which keys and values have a one-to-many mapping
@rimbu/multiset	provides a set in which elements can occur multiple times
@rimbu/ordered	provides the OrderedSet and OrderedMap collections, that keep insertion order
@rimbu/sorted	provides a SortedMap and SortedSet implementation, using compare functions to efficiently keep the elements sorted
@rimbu/stream	contains methods to easily manipulate sequences of data
@rimbu/table	provides various Table data structures where a combination of a row key and column key maps to a single value.
