🤔 DESCRIPTION

Lumie is a lightweight module that allows you to set up a scalable controllers architecture for your nodejs project.

✅ Maintainable
✅ Scalable
✅ Quick setup
✅ Easily testable

💾 INSTALLATION

npm install lumie

🔩 HOW IT WORKS

Lumie goes through the files and folders inside your controllers directory to find what we call "routing definitions".
Each controllers are defined in files, which export their routing definitions ( example )

By default, we use the name of the file that exports the routing definition to name the route

/ > controllers > cars.js will create the endpoints /cars/*
/ > controllers > admin > rules.js will create the endpoints /admin/rules/*
/ > controllers > users > users.routing.js will create the endpoints /users/*

⚙️ CONFIGURATION

const express = require("express");
const path = require("path");
const lumie = require("lumie");

const app = express();

lumie.load(app, {
  preURL: "api",
  verbose: true,
  ignore: ["*.spec", "*.action"],
  controllers_path: path.join(__dirname, "controllers")
});

const server = app.listen(3000, "127.0.0.1", () => {
  const { address, port } = server.address();
  console.log("Example app listening at http://%s:%s", address, port);
});

Options

Name	type	default value	Description
verbose	`boolean`	`false`	Will print or not the routes name in the console
preURL	`string`	`/`	Prefix your route URLs
ignore	`string[]`	`null`	Lumie will not try to find a routing definition in those files.
controllers_path	`string`	none, this option is required	The path of your controllers folder.
routing_files	`string`	`*.routing`	How you want to name routing files.
permissions	`function`	`null`	A function that takes in parameter a level access and returns an express middleware. This is useful if you want to restrict access for some URLs. With this option enabled, you will be able to set in each route configuration an option level that will be passed to your permission function ( example )

🎮 USAGE

Example: project/controllers/cars.js

const postCars = require("./cars-post.action");
const getCars = require("./cars-get.action");

module.exports = {
  path: "awesome-cars", // rename the path of the route (optional)
  '/': {
    post: {
      middlewares: postCars.middlewares,
      action: postCars.action,
      level: 'public'
    },
    get: {
      action: getCars.getAll,
      level: 'public'
    }
  },
  '/:id': {
    get: {
      action: getCars.getOne,
      level: 'public'
    }
  }
};

'/<name of your route>': {
        < get | put | delete | post >: {
            action: < function(req, res) >,
            level: < parameters of you permission function >, // Optional
            middlewares: < Array(function(req, res, next)) >// Optional
        }
    }

🌠 BEST PRACTICES

There is 2 common way to create a controller with Lumie, you can take a look here to learn how to implement them.

Minimal (sample): You only create one file which takes as name, the name of the controller you want to create. Then you define the routing definition and the functions. This method is recommended if you plan to have a small controller with few actions.
Structured (sample): You create a new directory with the name of the controller. Inside, you create:
- [your-controller-name].routing.js which contains the routing definition
- [your-controller-name].actions.js which contains the action functions of the controller.
- [your-controller-name].spec.js This one is optional

If your controller is pretty heavy, with a lot of functions, we recommend to create one file per action (create-user.action.js, get-user.action.js, etc… ) (sample)
