Acebook

In this project, you are tasked with working on an existing application. A significant part of the challenge will be to familiarise yourself with the codebase you've inherited, as you work to improve and extend it.

Documentation

More documentation of the codebase and its architecture can be found here. It's recommended you all read this after making sure the whole setup below worked for everyone. Then work together on a diagram describing how the application works.

A template Miro board for your diagrams can be found here. Make sure your validate your diagrams with your coach.

Quickstart

Install Node.js

1. Install Node Version Manager (NVM)

   brew install nvm
   

   Then follow the instructions to update your ~/.bash_profile.
2. Open a new terminal
3. Install the latest version of Node.js, currently 18.1.0.

   nvm install 18
   

Set up your project

1. Fork this repository
2. Rename your fork to acebook-<team name>
3. Clone your fork to your local machine
4. Install Node.js dependencies for both the frontend and api directories.

   ; cd api
   ; npm install
   ; cd ../frontend
   ; npm install
   

You might get warning messages about the installed dependencies at this point. You can ignore them, as long as the installation process doesn't fail. If the setup fails at this point, don't wait for too long and reach out to your coach.

5. Install an ESLint plugin for your editor. For example: linter-eslint for Atom.
6. Install MongoDB

   brew tap mongodb/brew
   brew install [email protected]
   

   Note: If you see a message that says If you need to have [email protected] first in your PATH, run:, follow the instruction. Restart your terminal after this.
7. Start MongoDB

   brew services start [email protected]
   

How to run the server and use the app (as a human)

1. Start the server application (in the api directory)

Note the use of an environment variable for the JWT secret

; cd api
; JWT_SECRET=f6d278bb34e1d0e146a80b16ec254c05 npm start

2. Start the front end application (in the frontend directory)

In a new terminal session...

; cd frontend
; npm start

You should now be able to open your browser and go to http://localhost:3000/signup to create a new user.

Then, after signing up, you should be able to log in by going to http://localhost:3000/login.

After logging in, you won't see much but you can create posts using PostMan and they should then show up in the browser if you refresh the page.

How to run automated tests

The automated tests run by sending actual HTTP requests to the API. Therefore, before anything, you'll need to start the backend server in test mode (so that it connects to the test DB).

Note the use of an environment variable for the JWT secret

# Make sure you're in the api directory
; cd api

; JWT_SECRET=f6d278bb34e1d0e146a80b16ec254c05 npm run start:test

You should leave this running in a terminal.

Then, you can either run tests for the backend or the frontend following the steps below.

Running tests for the backend

Run the tests in a new terminal session:

# Make sure you're in the api directory
; cd api

; JWT_SECRET=f6d278bb34e1d0e146a80b16ec254c05 npm run test

Running tests for the frontend

Start the front end in a new terminal session

# Make sure you're in the frontend directory
; cd frontend

; JWT_SECRET=f6d278bb34e1d0e146a80b16ec254c05 npm start

Then run the tests in a new terminal session

# Make sure you're in the frontend directory
; cd frontend

; JWT_SECRET=f6d278bb34e1d0e146a80b16ec254c05 npm run test

Mongo Playground

If you're not sure how to query your database and you need to test out a few approaches, we recommend you use Mongo Playground.

• Use the left pane to create a mock-up of your collection
• Use the middle pane to try out a new query
• See the results in the right pane

MongoDB Connection Errors?

Some people occasionally experience MongoDB connection errors when running the tests or trying to use the application. Here are some tips which might help resolve such issues.

• Check that MongoDB is installed using mongo --version
• Check that it's running using brew services list

If you have issues that are not resolved by these tips, please reach out to a coach and, once the issue is resolved, we can add a new tip!
