// BASE SETUP
// =============================================================================

// call the packages we need
const express = require("express"); // call express
const app = express(); // define our app using express
const bodyParser = require("body-parser");
const path = require("path");
const mongoose = require("mongoose");
const authController = require("./controllers/auth");
const mangaController = require("./controllers/manga");
const userController = require("./controllers/user");
require("dotenv").config({ silent: true });

app.set("superSecret", process.env.SECRET); // secret constiable

// configure app to use bodyParser()
// this will let us get the data from a POST
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

// REGISTER OUR ROUTES -------------------------------
const router = express.Router(); // get an instance of the express Router
app.use((req, res, next) => {

// all of our routes will be prefixed with /api/v#
app.use(`/api/${process.env.API_VERSION}`, router);

// Serve Swagger UI at https://mangadbv2.herokuapp.com
app.use("/", express.static(path.join(__dirname, "docs")));

//(accessed at GET https://mangadbv2.herokuapp.com/api/v#)

// HANDLE USER RELATED ROUTES
// ===========================================================================

// Request token generator at /auth
// Get Json web token authentication
