Final project for Scotland class 3 - New Scots Got Talent

Get started

1. Create a fork of this project
2. Clone your fork into your local machine.
3. In your Terminal 'git remote add upstream url_of_your_project', and then check if you add with the command 'git remote -v'
   an upstream remote pointing to the main CYF repo (to be able to pull updates from your team members)

After cloning the project, we will create the local database that the project will use.

Database

• Open the terminal, and cd into server
• Create your database: createdb final_project
• npm run recreate-db:local (this will create and populate your new team's DB with the data your colleague added)

Your actual database schema will go to server/db/recreate-schema.sql and you can add sample test data in server/db/populate-db.sql

Test it all works

Now let us test that the whole stack works (the React frontend connects to the Node API which connects to the Postgres Database )

• Open a terminal, navigate to the root of the project and do npm install
• cd into server and run npm run dev
• On a different terminal, cd into client and run npm run dev

Once the React website opens in a browser. Navigate to the Status page, and you should see two users listed in the page. This means everything works fine.

Development Process

Read the Development process.

IMPORTANT: Make sure you read and understand the development proces guidelines before starting any work. Ask mentors for explanation if you have any questions.

Project structure

The project is divided into client folder for the React frontend, and a server folder for the node API and database side.

This structure is called a mono repo. As opposed to having two repos (one for client, another for server), we opted for a monorepo. You can read more about monorepos.

The Client

The client is a React app created with create-react-app. In addition to the default setup, we have added React Router with 3 routes for testing

• The components live in the components folder. When the project gets bigger, we might separate them into logical folders (i.e. components/admin for admin-related components, and components/profile for user profile-related components)

• The api folder contains modules to call a specific API, i.e. when you add a new endpoint to list, craete and update jobs then you can add a new module called api/jobs.js that can contain methods such as getJobs, createJob, deleteJob ....

• The tests live with the modules. Some projects put the tests in a top-level folder __tests but we chose that they live with the components they test, i.e. a test for About.js will be in a file called About.test.js at the same level in the folder.

• Styles are in the folder client/styles. Each file in that folder will contain styles related to a specific component (and have the same name), i.e. a component called About.js might define styles in styles/About.css and import them.

Component library

We will use Semantic UI component library for the projects. Check out the documentation to get familiar with it.

Server

The API is implemented using Express framework. We have added some extra functionality, such as a simple authentication solution.

• db folder contains the script to run to create the database, the schema and seed it with sample data. Whenever you want to add a new database table or change an existing, you will likely change it in db/recreate-schema.sql.

• services folder contain database services. These are modules to manipulate a certain entity in the database. For example, if you have a table called documents, you might add a module services/database/documents that will expose methods like addDocument, getDocumentById and implement an SQL statement to perform the required functionality.

• api When you add a new API, for example for managing questions. You can add it at api/index.js. This will define the prefix so for example,

const questions = require("./questions");
router.use("/questions", questions);

and in questions module you will define the routes. Note these will all be prefixed with questions.

For example

// questions.js
const express = require("express");
const router = express.Router();

// This route is GET /questions/ (because everything in this file is "mounted" on the prefix questions from the previous step)
router.get("/", (req, res) => {
  res.send("All good");
});

module.exports = router;

This structure using Express.Router allows our code to be modular and minimise conflict between team members. You can read more about Express Router

Typically a server-side user story will involve:

1. Define a table in db/recreate-schema.sql
2. Create an API endpoint api/some_table.js
3. Create a service under services/databases/some_table.js (this will contain the SQL to connect the API and the database)

Authentication and Authorisation

The project has routes and services to implement an authentication / authorisation solution. It depends on passportjs library, and implements an authentication strategy called JWT. To understand more authentication, you can read this article.

To test authentication:

• In Postman, do a GET on http://localhost:4000/api/status/protected. You should receive a 403 (Forbidden) as a response.

• Register a user by doing a POST to http://localhost:4000/auth/register with the body looking like:

{
  "email": "[email protected]",
  "password": "mypassword"
}

Don't forget to set the content-type to raw and application/json

• Now you can login by doing a POST to http://localhost:4000/auth/login with a body similar to:

{
  "email": "[email protected]",
  "password": "mypassword"
}

This will bring you back a token. Copy the token you get in the response.

• Now, we can use this token for the status/protected route. Do a GET request to http://localhost:4000/api/status/protected and add a header with the name Authorization and the value: Bearer the_token_from_previous step, i.e. Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VySWQiOjMsImlhdCI6MTU2NTkwOTU4OX0.qidn4r7nrolFByyfd956Kh8BkOhwcaUSzyUK0V7su1c
