MERN Starter by Jay Jay Cayabyab

This repository includes a boilerplate application that is designed as a launchpad for initializing boilerplate applications.

  • The structure of the project in its current state assumes that the project will have two separate servers: one for the server-side and one for the client side.
  • This starter assumes that you will be deploying to heroku and contains code that allows this to be done easily; however, this only pertains to the postbuild script inside of the package.json file. Otherwise, all other heroku-friendly changes are compatible with other deployment services.

Table of Contents

  1. To-do before working on your project
  2. For heroku deployment
  3. Installed dependencies
  4. Completed steps

To-do before working on your project:

  • Edit the .gitignore file to include dev.js.
  • Run the following code:
git rm --cached dev.js
npm i
cd client
npm i
  • Delete the contents of this README.md and replace with # {your-project-name}.
  • Add dev.js to your .gitignore file.
  • Create a new MongoDB. mLab can be found here.
  • Generate new Google OAuth api keys here.
  • Update the keys in your dev.js file.

For a separate github repo:

  • Run the following code:
git remote set-url origin {repo-url}
git add README.md
git commit -m "initial commit"
git push -u origin master

For heroku deployment:

For heroku initialization:
  • Ensure git is installed. Preferably, update the github repo with the instructions above.
  • Ensure Heroku CLI is installed. You can download it here.
    • If not logged in, run heroku login.
  • Run heroku create. This will log a git repository connected to heroku.
  • Run
git remote add heroku {heroku git repository}
git push heroku master
  • On heroku.com, navigate to settings.
  • Add a MONGO_URI key-value pair in Config vars.
    • It would be preferred that this mongo database is unique from the development database.
For consequent deployments:
  • Ensure that all files are saved and everything is committed
  • Run
git push heroku master

This starter installs the following dependencies:

Server-side:
  • Express
  • Nodemon
  • Concurrently
  • Mongoose
  • body-parser
  • Passport.js
  • Google Passport Strategy
  • Cookie Session
Client-side:
  • create-react-app dependencies
  • Redux
  • React-Redux
  • Redux-Form
  • Redux-Thunk
  • axios
This starter automatically completes the following steps:
  • Creates an Express app in index.js and initializes it to PORT 5000.
  • Formats the package.json file:
    • Adds the node and npm engines for deployment purposes.
    • Creates two separate node instances on the back-end and the front-end.
    • Uses concurrently to run the entire application i.e. both the server and client node instances with npm run dev.
  • Initializes a config folder with logic for prod vs. dev routing.
    • Provides key templates for googleClientID, googleClientSecret, cookieKey, and mongoURI.
  • Hooks up body-parser middleware to Express application.
  • Contains examples of Express routes, Mongoose models, and Express services.
  • Sets up Redux logic around store and dispatch.
  • Sets up react-router logic in App.js.
  • Contains examples of Redux actions and reducers.
  • Proxies HTTP requests from the front-end to the back-end server route /api.
  • Handles authentication flow using Passport.js, CookieSession, and Google OAuth Strategy.
    • Creates some routes for handling authentication by the front-end:
    1. /auth/google for entering OAuth flow
    2. /api/current-user for return a JSON object of the current user
    3. /api/logout for logging the user out
    • Creates a "users" collection within the database.
      • This user has the following properties:
        • id: this is given by the OAuth service and is used to ensure there are no duplicate user documents.
        • firstName, lastName: contain the first and last name of the user.
    • Adds a requireLogin() middleware to be used within the backend to check if users are logged in before an HTTP request is made.
    • Passport makes the user available via the req.user object.
