Social network for developers, built on the MERN stack

DevConnector 2.0

Social network for developers

This is a MERN stack application from the "MERN Stack Front To Back" course on Udemy. It is a small social network app that includes authentication, profiles and forum posts.

Updates since course published

Such is the nature of software, things change frequently and packages are continuously evolving. Hopefully the below will help you adjust your course code to manage the most notable changes.

Changes to GitHub API authentication

Since the course was published, GitHub has depreciated authentication via URL query parameters You can get an access token by following these instructions For this app we don't need to add any permissions so don't select any in the scopes. DO NOT SHARE ANY TOKENS THAT HAVE PERMISSIONS This would leave your account or repositories vulnerable, depending on permissions set.

It would also be worth adding your default.json config file to .gitignore If git has been previously tracking your default.json file then...

git rm --cached config/default.json

Then add your token to the config file and confirm that the file is untracked with git status before pushing to GitHub. GitHub does have your back here though. If you accidentally push code to a repository that contains a valid access token, GitHub will revoke that token. Thanks GitHub 🙏

You'll also need to change the options object in routes/api/profile.js where we make the request to the GitHub API to...

const options = {
  uri: encodeURI(
    `https://api.github.com/users/${req.params.username}/repos?per_page=5&sort=created:asc`
  ),
  method: 'GET',
  headers: {
    'user-agent': 'node.js',
    Authorization: `token ${config.get('githubToken')}`
  }
};

npm package request depreciated

As of 11th February 2020 request has been depreciated and is no longer maintained. We already use axios in the client so we can easily change the above fetching of a users GitHub repositories to use axios.

Install axios in the root of the project

npm i axios

We can then remove the client installation of axios.

cd client
npm uninstall axios

Client use of the axios module will be resolved in the root, so we can still use it in client.

Change the above GitHub API request to..

const uri = encodeURI(
  `https://api.github.com/users/${req.params.username}/repos?per_page=5&sort=created:asc`
);
const headers = {
  'user-agent': 'node.js',
  Authorization: `token ${config.get('githubToken')}`
};

const gitHubResponse = await axios.get(uri, { headers });

You can see the full change in routes/api/profile.js

uuid no longer has a default export

The npm package uuid no longer has a default export, so in our client/src/actions/alert.js we need to change the import and use of this package.

change

import uuid from 'uuid';

to

import { v4 as uuidv4 } from 'uuid';

And where we use it from

const id = uuid();

to

const id = uuidv4();

Quick Start

Add a default.json file in config folder with the following

{
  "mongoURI": "<your_mongoDB_Atlas_uri_with_credentials>",
  "jwtSecret": "secret",
  "githubToken": "<yoursecrectaccesstoken>"
}

Install server dependencies

npm install

Install client dependencies

cd client
npm install

Run both Express & React from root

npm run dev

Build for production

cd client
npm run build

Test production before deploy

NODE_ENV=production node server.js

Check in browser on http://localhost:5000/
