japack v0.1.1

japack library

japack is a lightweight tool developed by the shake programming language team as a library to represent a java-style package storage in javascript.

Installing

npm

npm install japack

yarn

yarn add japack

Usage

import { pImport, add as addPackage, require as requireFunction } from 'japack';

Registering a package

You can register a package by calling the add function.

addPackage({
    "io.github.shakelang.japack.test" : it => requireFunction(`${__dirname}/test.js`)
});

Importing a package

This package will now be available using the pImport function.

const test = pImport(`io.github.shakelang.japack.test`);

You can also create your own japack package host. This will be handled by the japack library, but not contain the packages of the global japack host and not store the packages in the global japack host.

Own japack host

import { createPackageSystem } from 'japack';

const packages = createPackageSystem({
    "io.github.shakelang.japack.test" : requireFunction(`${__dirname}/test.js`)
});

You can of course also use the pImport and add functions from the global japack host.

const { pImport, add: addPackage } = packages;

Inline japack installation

There is also the possibility to add a inline japack instance to your package. This is useful if you want to use the japack library in your package without the need to install the japack dependency. One advantage of this is that japack will use the installed japack version instead of the inline version if it can find it. Also with the inline version you can import packages from other inline japack instances. The compressed version of the inline japack instance can be easily added to your javascript file and is only about 1000 characters long.
