@rimbu/base

This package contains mostly utilities to implement the other Rimbu collections. The types are not exported by any of the other packages, but are internally used by most of them.

Most important are the exported Arr methods that are used at the basis of all the block-based data structures. These methods should be as correct and efficient as possible.

For complete documentation please visit the Rimbu Docs or the Rimbu API Docs

Installation

Yarn/NPM

yarn add @rimbu/base

npm i @rimbu/base

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/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

Because Rimbu uses advanced types, this may slow down the type checking part when running your code. If you’re able to rely on your code editor to provide type errors, you can skip the Deno type check using the --no-check flag:

deno run --import-map import_map.json --no-check src/main.ts

Usage

import { Arr } from '@rimbu/base';

const arr = [1, 2, 3];
console.log(Arr.mod(arr, 1, (v) => v + 1));
// [1, 3, 3]

console.log(arr);
// [1, 2, 3]
