Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

npm version Deno

Licence

@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 directly see the Rimbu Core API Docs.

Or Try Out Rimbu in CodeSandBox.

Installation

Compabitity

Yarn / NPM / Bun

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

For yarn:

yarn add @rimbu/core

For npm:

npm i @rimbu/core

For bun:

bun add @rimbu/core

Deno

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/[email protected]/"
  }
}

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

Usage

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']]

Using the creation 'menu'

The same code using the creation 'menu':

import Rimbu from '@rimbu/core/menu';

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

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

const map = Rimbu.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/proximity | provides ProximityMap, that retrieves values based on key proximity | | @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. |
