FullStack setup (Node.js, React.js and MongoDB)

pacheco profile image Thiago Pacheco Updated on ・7 min read

Whenever I have to create a new project, I prefer to keep my stack with only one language. So I love use javascript for everything, with Node.js, Express.js, React.js and I really like to use NoSQL databases like MongoDB in this case.

So I decided to share my experience of setting up this environment from scratch.

First, let's create a folder and generate our package.json file for this project.

$ mkdir node-react-starter
$ cd node-react-starter
$ npm init -y
Enter fullscreen mode Exit fullscreen mode

Now, let's install the project dependencies

$ npm install --save express body-parser mongoose
Enter fullscreen mode Exit fullscreen mode

In this project we use Express.js, a very popular framework for Node.js applications.
body-parser is used to parse incoming request bodies in a middleware before your handlers, available under the req.body property.
Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment.

Then, install the development dependencies

$ npm install --save-dev nodemon concurrently
Enter fullscreen mode Exit fullscreen mode

nodemon is a package that runs the node.js application and listen to any file change, updating the entire app.

Concurrently allows us to run multiple npm commands at the same time.

After installing the dependencies, you should get a file like this:

package.json file example

Let's create the project structure

$ mkdir models routes
$ touch index.js
Enter fullscreen mode Exit fullscreen mode

Open the index.js file and add the following code:

//  index.js

const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser');

const app = express();

mongoose.Promise = global.Promise;
mongoose.connect(process.env.MONGODB_URI || `mongodb://localhost:27017/node-react-starter`);

app.use(bodyParser.json());

const PORT = process.env.PORT || 5000;
app.listen(PORT, () => {
  console.log(`app running on port ${PORT}`)
});
Enter fullscreen mode Exit fullscreen mode

After this, you can add a run script inside your package.json file, under scripts:

"server": "nodemon index.js"
Enter fullscreen mode Exit fullscreen mode

At this point, you can run your backend and have a successful connection with the mongodb (MongoDB must be up and running). You can run the script you just created like so:

$ npm run server
Enter fullscreen mode Exit fullscreen mode

Let's initiate our version control to keep track of every change. But first we need to add a .gitignore file in the root of our project with the following content:

node_modules
.idea
Enter fullscreen mode Exit fullscreen mode

Then, we initiate our version control

$ git init
$ git add .
$ git commit -am "first commit"
Enter fullscreen mode Exit fullscreen mode

We successfully created our backend structure, now let's jump to the frontend.

Now, let's create a React app with create-react-app.

$ create-react-app client
Enter fullscreen mode Exit fullscreen mode

Now, in the client directory we have to add our dependencies.
Here we are going to use yarn to add this dependencies.

$ cd client
$ yarn add axios
Enter fullscreen mode Exit fullscreen mode

axios is a very popular promise based HTTP client for the browser and node.js.

For react-scripts >= 0.2.3

For the current react version (and any other react-scripts > 0.2.3), you can simply add the following line to your package.json file in the client directory and that will allow you to proxy your front-end requests to the back-end app.

"proxy": "http://localhost:5000"
Enter fullscreen mode Exit fullscreen mode

For react-scripts < 0.2.3

If you are using an older version of react-scripts you might need to add the following configuration to be able to connect the front-end with the back-end:

$ cd client
$ yarn add http-proxy-middleware
Enter fullscreen mode Exit fullscreen mode

http-proxy-middleware is used to create a proxy from our react app to the backend app while on development.

We can now add the config file to setup the proxy to make requests from our frontend to our backend application.
Remember to add this configuration only if you are using an older react version, being react-scripts < 0.2.3.

In the directory /client/src, add the file setupProxy.js with the following content

// /client/src/setupProxy.js

const proxy = require('http-proxy-middleware')

module.exports = function(app) {
    app.use(proxy('/api/*', { target: 'http://localhost:5000' }))
}

Enter fullscreen mode Exit fullscreen mode

In the package.json in the root of the project, let's add the following run scripts:

"client": "npm run start --prefix client",
"server": "nodemon index.js",
"dev": "concurrently --kill-others-on-fail \"npm run server\" \"npm run client\"",
"start": "node index.js"
Enter fullscreen mode Exit fullscreen mode

Now your package.json file should look like this:

{
  "name": "node-react-starter",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "client": "npm run start --prefix client",
    "server": "nodemon index.js",
    "dev": "concurrently --kill-others-on-fail \"npm run server\" \"npm run client\"",
    "start": "node index.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "body-parser": "^1.19.0",
    "express": "^4.17.1",
    "mongoose": "^5.6.3"
  },
  "devDependencies": {
    "concurrently": "^4.1.1",
    "nodemon": "^1.19.1"
  }
}

Enter fullscreen mode Exit fullscreen mode

Now you are able to run the project with the following command:

$ npm run dev
Enter fullscreen mode Exit fullscreen mode

This will run the backend application on port 5000, and the frontend on port 3000.
You should see the react application running on http://localhost:3000

To make our project production ready, we need to add the following lines in our index.js file, right after the app.use(bodyParser.json()) call:

if (process.env.NODE_ENV === 'production') {
  app.use(express.static('client/build'));

  const path = require('path');
  app.get('*', (req,res) => {
      res.sendFile(path.resolve(__dirname, 'client', 'build', 'index.html'))
  })

}
Enter fullscreen mode Exit fullscreen mode

This will redirect all the requests to our frontend application, unless we specify any route before this code.

Now let's create a simple interaction to see the proxy connection in action

Add the file Product.js inside the directory /models and insert the following code:

// /models/Product.js

const mongoose = require('mongoose');
const {Schema} = mongoose;

const productSchema = new Schema({
    name: String,
    description: String,
})

mongoose.model('products', productSchema);
Enter fullscreen mode Exit fullscreen mode

Let's create a route for our backend API.

Add the file productRoutes.js inside the directory /routes and insert the following code:

// /routes/productRoutes.js
const mongoose = require('mongoose');
const Product = mongoose.model('products');

module.exports = (app) => {

  app.get(`/api/product`, async (req, res) => {
    let products = await Product.find();
    return res.status(200).send(products);
  });

  app.post(`/api/product`, async (req, res) => {
    let product = await Product.create(req.body);
    return res.status(201).send({
      error: false,
      product
    })
  })

  app.put(`/api/product/:id`, async (req, res) => {
    const {id} = req.params;

    let product = await Product.findByIdAndUpdate(id, req.body);

    return res.status(202).send({
      error: false,
      product
    })

  });

  app.delete(`/api/product/:id`, async (req, res) => {
    const {id} = req.params;

    let product = await Product.findByIdAndDelete(id);

    return res.status(202).send({
      error: false,
      product
    })

  })

}
Enter fullscreen mode Exit fullscreen mode

We can now import the models and routes files inside our index.js like so:

// /index.js
const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser');

// IMPORT MODELS
require('./models/Product');

const app = express();

mongoose.Promise = global.Promise;
mongoose.connect(process.env.MONGODB_URI || `mongodb://localhost:27017/node-react-starter`);

app.use(bodyParser.json());

//IMPORT ROUTES
require('./routes/productRoutes')(app);

if (process.env.NODE_ENV === 'production') {
  app.use(express.static('client/build'));

  const path = require('path');
  app.get('*', (req,res) => {
      res.sendFile(path.resolve(__dirname, 'client', 'build', 'index.html'))
  })

}

const PORT = process.env.PORT || 5000;
app.listen(PORT, () => {
  console.log(`app running on port ${PORT}`)
});
Enter fullscreen mode Exit fullscreen mode

Now if we run the project we are able to make requests to our simple product api using the url http://localhost:5000/api/product.
Here we can get, insert, update and delete a product.

Back to the react application, lets add a service to make requests to the backend application.
Inside the folder /client/src create a folder called services and add a file productService.js with the following content:

//  /client/src/services/productService.js

import axios from 'axios';

export default {
  getAll: async () => {
    let res = await axios.get(`/api/product`);
    return res.data || [];
  }
}
Enter fullscreen mode Exit fullscreen mode

Now let's edit the App.js file, adding a simple UI that shows a list of products:

// /client/src/App.js

import React, { useState, useEffect } from "react";

// SERVICES
import productService from './services/productService';

function App() {
  const [products, setproducts] = useState(null);

  useEffect(() => {
    if(!products) {
      getProducts();
    }
  })

  const getProducts = async () => {
    let res = await productService.getAll();
    console.log(res);
    setproducts(res);
  }

  const renderProduct = product => {
    return (
      <li key={product._id} className="list__item product">
        <h3 className="product__name">{product.name}</h3>
        <p className="product__description">{product.description}</p>
      </li>
    );
  };

  return (
    <div className="App">
      <ul className="list">
        {(products && products.length > 0) ? (
          products.map(product => renderProduct(product))
        ) : (
          <p>No products found</p>
        )}
      </ul>
    </div>
  );
}

export default App;

Enter fullscreen mode Exit fullscreen mode

At this point, you can run the application again using the command npm run dev, and you will see the following screen:

Use a HTTP client like Postman or Insomnia to add some products. Make a POST request to http://localhost:5000/api/product with the following JSON content:

{
  "name": "<product name>",
  "description": "<product description here>"
}
Enter fullscreen mode Exit fullscreen mode

Now, you will be able to see a list of products rendered on the screen, like so:

I hope you may find this tutorial useful and in the following days I will continue this tutorial showing how to Dockerize this app.

Hi Thiago, Thank you so much for this great tutorial. I followed the whole tutorial exactly as you mentioned and at the end when inserting the post requests to include some products... the console was showing this message:
GET localhost:3000/api/product 404 (Not Found)
dispatchXhrRequest @ xhr.js:178 ........

and then I changed in productService.js, axios.get("/api/product) for axios.get(http://localhost:5000/api/product) and the whole app worked!

I have the proxy in the package.json included and everything...but not sure if I missed something..do you know why this happens?Thank you in advance!!!

Another thing, you should not include the localhost in your axios.get function call.
It should be axios.get("/api/product", ...).

The base URL definition is already set at the beginning of the application when we build the server and define a port, in this case 5000.

Hi Oscar,

Are you getting this error in the front-end console or is it in an HTTP client?
If this is in your react app, it seems like something is wrong with the proxy config.

I think I found the issue. I had included the sentence "proxy": "localhost:5000" inside the package.json belonging to the server, and not inside the package.json of the client(react app). May be that one the problem Thiago? Because now I´m not getting any errors.

Hi Thiago, This is a best useful and easily guide for beginner like me but I am facing a some problem...

Last year I have done it finished once and it work completely in my macbook but now I do one more on VMware. Everything almost work but it stuck in front-end part.

My app can GET and POST to localhost:5000, data was completely send to database but now it never found "product" from database cause my localhost:3000 always show "No products found" and white blank page...

I think because of client side but I am not sure which code cause this. Could you please adviseme Thiago. Thanks you !

Hi Melonfrappe!

Can you check in your browser's console and network tab what are the errors you get while trying to fetch the data?
It smells like a proxy error maybe.

Hi Thiago! Great article.

I have one question. Once I send a post request for new products, and I look at the app, I just see bullets, but no product names or descriptions. Any idea why that might be?

Thanks!

Hey Tomrains, thank you! :)

If you can see the bullets in your view after creating products, this should probably be a problem in your view.
I recommend you put a console.log(product) inside the renderProduct arrow function, right in the beginning.
Let me know what you got there.

Humm I see, actually the problem must be when you are creating the products.
What response do you get after making the post request to create a product?

You should get something like this:

{
"error": false,
"product": {
"id": "5dab7eb6fc634a193f1f05f6",
"name": "product 1",
"description": "description",

Oh I see tomrains, you are sending a post request with a x-www-form-urlencoded, when you should actually be sending a json.
I think in postman you should select the option raw.

Hi Thiago,
I have a similar problem to the one reported by @tomrains , but the answer you gave did not allow me to solve it.
(Note: I'm new to Postman)
the response I get for localhost:5000/api/product?name=to... is
{"error":false,"product":{"id":"5ee204bbf1af38409c11d4de","_v":0}}
the response code is 201 Created.
In the Pretty - Raw - Preview section, I can't edit, it's read only
I added a Content-type: raw section in the headers but that didn't change anything.
I tried using curl, with this command: curl --location --request POST "localhost:5000/api/product" --header "Content-Type: raw" -d '{"name":"toto","description":"tata"}'
but the result seems to be the same...

Here's a screenshot of my postman app:

Hi Francis.

In your screenshot, I can see that you are sending query params with the values when you should actually be sending body data in postman.
You can select the body option and you will have a raw option below it.

For the proxy issue follow the steps below.

Replace the ' const proxy' in setupProxy.js file with this.

const { createProxyMiddleware } = require('http-proxy-middleware');

module.exports = function(app) {
app.use('/api',
createProxyMiddleware({
target: 'localhost:5000',
changeOrigin: true

Veronika,

Does the error persist once you modify the line:

mongoose.connect(process.env.MONGODB_URI || 'mongodb://localhost:27017/node-react-starter',{ useNewUrlParser: true });

as suggested by the Deprecation Warning?

What is the prompt error if so?

Thread Thread
pacheco profile image
Thiago Pacheco Author

This deprecation warning should not prevent you from running the app, but the rpacheco suggestion should do the trick.

You can also add this config on another line, like so:

mongoose.set("useNewUrlParser", true);

You might also find other deprecation warnings in the future, follow a list below in case you need it.

mongoose.set("useFindAndModify", false);
mongoose.set("useCreateIndex", true);
mongoose.set("useUnifiedTopology", true);

Let me know if that worked for you.

Thiago Pacheco Author

Hi Csaba,

By the error, it could be something wrong with the definition of this app.delete method.
Does your backend log any error in the terminal when you test this endpoint?

If everything is correct in your code, the error could be the ID you are passing in the URL.
As this is just a simple tutorial and I wanted it to be short, it does not have validations but, in a final application, it should contain a lot of validations on the data we are trying to execute actions.

My suggestion to you is to check if the ID you are passing to the URL http://localhost:5000/api/product/<YOUR-PRODUCT-ID> is a valid ID.

Let me know if this helped you solve the problem and do not hesitate to ask if you have more questions.

Hi Leo,

You can create a file launch.json inside the folder .vscode with the following code:

{
"version": "0.2.0",
"configurations": [
{
"name": "Launch via npm",
"type": "node",
"request": "launch",
"cwd": "${workspaceFolder}",
"runtimeExecutable": "npm",
"runtimeArgs": ["run-script", "dev"],
"port": 9229

Hi Leo,

Sorry, You should also have a new debug script in your package.json file. Add the following script to your package.json:

"debug": "nodemon --nolazy --inspect-brk=9229 index.js",

Also, update the launch.json runtimeArgs to use this new script:

"runtimeArgs": ["run-script", "debug"],

Great guide, thank you!

Question, any idea why the proxy breaks when using a api url more than two levels deep? "/api/blocks" works whereas "/api/blocks/all" does not. Everything else is the same and api routes work separately.

Tried "/api" and "/api/**" in setupProxy.js to no avail.

Collapse

Hi Alg, sorry for the delayed answer and thank you for your comment.

This deep routes should work as the other ones. What I recommend to you is to use the proxy config that react supports now.
You can simply put the following line in your package.json file:
"proxy": "localhost:5000"

This should do the trick.

i want to set proxy in setupProxy file.

Thanks

Hi there.

I recommend you to stick with the package.json proxy approach, now that it is supported in the latest version (I don't know exactly since when lol).

I will probably update that in the post as soon as I can.

Hello Rajat,

Can you tell me if testing the backend and frontend separately works correctly?
I just gave it another try here and everything works perfect.

Another option you could try is to config the proxy directly in the package.json, the latest versions of react supports this. It is as simple as adding the following line to your package.json file:
"proxy": "localhost:5000"

Hello,

As we are all in this quarentine, I'm working right now on a tutorial for that. I will try to post it today. :)

What to do if we want to deploy multiple apps? They must share the same database, correct?

Hi Jack,

That depends on the project you are working on.
Currently, with almost everything migrating to microservices approach, it is common to have one database for each service/functionality.

Hello there, can you confirm what errors do you get in the backend and frontend logs of your application?

Very confusing documentation.
For example: dev-to-uploads.s3.amazonaws.com/i/...

Which package.json?

Hi Mustafa, how are you?

I am sorry if that was not that clear, it was my first article so I am still improving it.
But as I said in this part, it is the package.json located in the root of the project, which means the file related to the backend part.

Let me know if I can help you with anything else.

Sorry if I am being rude.

For example, in your doc, you says process.env.MONGODB_URI or process.env.NODE_ENV but all that give errors "undefined"

so what can I do?

Hi Mustafa,

These variables when working on the localhost will be undefined, but that should not trigger errors because there is a checking on each of them applying another value in case they are undefined.

These are the environment variables that can make the app production-ready. For example, the MONGODB_URI will be used as your production mongo URL and the NODE_ENV will be used to render the correct front-end application in case it is set to production.

They are used in the following tutorials (found at the end of the article) about how to dockerize and deploy this app.

Thanks for the reply. I have sent the message you via instagram dm. I need more explanations.

Anyway, you said in your doc:
"Now if we run the project we are able to make requests to our simple product api using the url localhost:5000/api/product.
Here we can get, insert, update and delete a product."

But I tried it with postman but it waits too long. nothing returns.

For instance:

localhost:5000/api/product?name=mu...

it says, "sending request..." and it stucks.

Small correction - productRoutes.js referenced as productRoute.js (singular) in this page.

It seems like you do not have the http-proxy-middleware package installed.
