container-js's Introduction

ContainerJS

An experiment with the objective of bringing rational objects using a solid abstraction to provide methods and attributes that follow a fixed pattern and increase the readability and coherence of the code.

Versions

Info: DO NOT use the development version, use a branch stable version.

Version	Branch
development	main
1.0.4	v1.0.4
1.0.3	v1.0.3
1.0.1	v1.0.1
1.0.0	v1.0.0

How it works?

ContainerJS is a library that implements a new JavaScript constructor, Container, among its functionalities its main use is to isolate an object in a solid abstraction, allowing safe and coherent operations to be performed with it and keeping it in its initial type, which prevents unwanted behaviors.

A Container can also provide a lot of generic functions to handle, edit and manage the data as it was inspired by tools like Linq (from .NET) and py Linq (an implementation of Linq in Python).

Interesting use cases

Getting data selectively

A container allows recursive operations, one of those possibilities is the ability to get ordered data, such as "the first 5 items of an iterable object", "the last 3 items of an iterable object" or "the first 5 items of an iterable object skipping two objects".

Examples:

const MyContainer = Container.from([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]);

//Will return the first 5 items ([1, 2, 3, 4, 5])
MyContainer.first(5);

//Will return the last 3 items ([10, 9, 8])
MyContainer.last(3);

//Will return the first 5 items skipping 3 ([4, 5, 6, 7, 8])
MyContainer.skip(3).first(5);

Unifying data management

A container is capable of dynamically detecting its type when being created, from that it allows the management of data in a unified way using generic methods. It currently supports popular JavaScript types such as Array, Object, Set and Map.

Examples:

const MyContainer = Container.from([]);

MyContainer.add(1); //Will add the item 1 to MyContainer content

const MyContainer = Container.from(new Set([]));

MyContainer.add(1); //Will add the item 1 to MyContainer content

const MyContainer = Container.from({});

MyContainer.add("a", 1); //Will add the item {a: 1} to MyContainer content

const MyContainer = Container.from(new Map());

MyContainer.add("a", 1); //Will add the item {a: 1} to MyContainer content

Installation

Via NPM:

npm install container-dot-js

Manually:

git clone https://github.com/EternalQuasar0206/container-js

Getting Started

To start using ContainerJS in a project just use the snippet:

import { Container } from "container-dot-js"

import { Container } from "/path/to/repo/container.js"

container-js's Issues

events being duplicated due to nested functions (main branch)

This is happening due to nested function calls inside functions, the current path to solve this is add a silent attributes getter (maybe setter) for event-free operations

Target: add/removeEventListener effects
Reproduce: execute npm run test with deno installed

toNumber internal method

Switch from "map" to "filter" to prevent using character replacement
