Modjulie

Modjulie is a server for building a library dynamically where required parts are added in the path and query string params of a http request.

It is heavily inspired by the work done by the financial times polyfill io service

Install

npm i modjulie --save

Usage

Quickstart

In order to get something serving you can use the example folder structure that has been set up and familiarise yourself with where everything goes before customising.

First create a symlink in your project directory to the example server folders

ln -s node_modules/modjulie/example/ ./example

create your server file

//index.js

const Modjulie = require( 'modjulie' );
const server = new Modjulie();
server.serve();

then run node index.js and you can access http://localhost:3000/v1/default?modules=moduleC to see the generated output

you can also take a look at example.index.html for how it is called from a script url in a page

Customisation

Modjulie defines a folderstructure as follows

Structure

versionsDirectory
├── v1
│   ├── headers (defaultHeaderSources)
│   │   ├── loader.json
│   │   └── namespace.js
│   ├── modules (moduleSourcesDirectory)
│   │   ├── moduleA
│   │   │   └── module.js
│   │   ├── moduleB
│   │   │   └── module.js
│   │   └── moduleC
│   │       └── module.js
│   └── presets (presetConfigurationDirectory)
│       └── default.json

Headers

This directory contains files that are added to the library regardless of other config at all times, use this to set up namespaces or do other base configuration

Modules

The modules directory contains folders with a module name and a module.js file within that contains the module code

Presets

presets define sets of modules that can be aliased to a name

these folders relate to the url structure as follows

/:version/:preset?modules=moduleA

where version is mandatory but the preset is optional

for example

/v1/default?modules=moduleA

Configs

The preset (presetConfigurationDirectory) json files each define a json array of module names that should be included as part of the package when the preset is used, for example;

[ "moduleA", "moduleB" ]

The headers (defaultHeaderSources) loader.json file works in a similar way but allows you to define the load order of your headers

[ "namespace.js", "init.js" ]
