Express-Template-FS

In this package, you will be able to set up your express app automatically which saves time for you to do your project so you don't have to worry about going through the same process of installing packages, creating folders for middleware, API, and models, creating the database.js file, and creating a .env file.

You will have to use npm install to install node modules. Anything with the word temp is meant to be changed in accordance with your project.

Middleware folder

• errorHandler

module.exports = (err, req, res, next) => {
  res.status(err.status || 500);
  res.json({
    error: {
      message: err.message || "Internal Server Error",
    },
  });
};

• notFoundHandler

module.exports = (req, res, next) => {
  const err = new Error("Not Found");
  err.status = 404;
  next(err);
};

database.js

const mongoose = require("mongoose");
require("dotenv").config();

const connectDB = async () => {
  const conn = await mongoose.connect(process.env.MONGO_DB_URL);
  console.log(`mongo connected: ${conn.connection.host}`);
};

module.exports = connectDB;

Models folder

Temp.js: Change the name of the file and its content in accordance with your project

const { model, Schema } = require("mongoose");

const TempSchema = new Schema({
  // your schema keys here along with their associated values
});

module.exports = model("Temp", TempSchema);

api/temp folders

• temp.controllers.js

  const Temp = require("../../models/Temp");
  
  // Everything with the word temp is a placeholder that you'll change in accordance with your project
    
  exports.fetchTemp = async (tempId, next) => {
    try {
      const temp1 = await Temp.findById(tempId).select("-__v");
      return temp1;
    } catch (error) {
      return next(error);
    }
  };
    
  exports.getTemp = async (req, res, next) => {
    try {
      const temps = await Temp.find().select("-__v");
      return res.status(200).json(temps);
    } catch (error) {
      return next(error);
    }
  };
    
  exports.createTemp = async (req, res, next) => {
    try {
      const newTemp = await Temp.create(req.body).select("-__v");
      return res.status(201).json(newTemp);
    } catch (error) {
      return next(error);
    }
  };
    
  exports.updateTemp = async (req, res, next) => {
    try {
      await Temp.findByIdAndUpdate(req.temp.id, req.body).select("-__v");
      return res.status(204).end();
    } catch (error) {
      return next(error);
    }
  };
    
  exports.deleteTemp = async (req, res, next) => {
    try {
      await Temp.findByIdAndRemove({ _id: req.temp.id }).select("-__v");
      return res.status(204).end();
    } catch (error) {
      return next(error);
    }
  };

• temp.routes.js

  const express = require("express");
  const {
    getTemp,
    createTemp,
    updateTemp,
    deleteTemp,
  } = require("./temp.controllers");
  const router = express.Router();
    
  // Everything with the word temp is a placeholder that you'll change in accordance with your project
    
  router.param("tempId", async (req, res, next, tempId) => {
    try {
      const foundTemp = await fetchTemp(tempId);
      if (!foundTemp) return next({ status: 404, message: "Temp not found" });
      req.temp = foundTemp;
      next();
    } catch (error) {
      return next(error);
    }
  });
    
  router.get("/", getTemp);
  router.post("/", createTemp);
  router.put("/:tempId", updateTemp);
  router.delete("/:tempId", deleteTemp);
    
  module.exports = router;

app.js

const express = require("express");
const connectDb = require("./database");
const cors = require("cors");
const morgan = require("morgan");
const app = express();
const notFound = require("./middlewares/notFoundHandler");
const errorHandler = require("./middlewares/errorHandler");
const tempRoutes = require("./api/temp.routes");
require("dotenv").config();

app.use(cors());
