Flask and create-react-app (MinerMagic) - Group 7

Requirements

1. npm install
2. pip install -r requirements.txt
3. npm i react-google-login in directory

Setup

1. Run echo "DANGEROUSLY_DISABLE_HOST_CHECK=true" > .env.development.local in the project directory

linting

1. E1101(no-member) - we felt this didn't add to code quality.
2. C0413(wrong-import-position) - we felt this didn't add to code quality.
3. W1508(invalid-envvar-default) - we felt this didn't add to code quality.
4. W0603(global-statement) - we wanted to have global variables
5. R0903(too-few-public-methods) - we felt this didn't add to code quality.
6. C0116(missing-function-docstring) - we felt that not every function needed a doc string, only certain ones
7. C0114(missing-module-docstring) - we felt that this docstring for the module wasn't neccessary
8. C0301(line-too-long) - we felt as long as the code wasn't too long its fine, we didn't need an arbitrary limit
9. R1705(no-else-return) - we felt this didn't add to code quality.
10. W0702(bare-except) - we felt this didn't add to code quality.
11. C0330(Wrong hanging indentation) - as long as the code wasn't too messy we felt we didn't need a specific format for hanging indentation

Setup for Socket.io with Flask and ReactJS

1. Open Cloud9 terminal in ~/environment. Run pip install flask-socketio
2. Run pip install flask-cors
3. cd into react-starter directory. Run npm install socket.io-client --save

Setup for Database

1. Install PostGreSQL: sudo yum install postgresql postgresql-server postgresql-devel postgresql-contrib postgresql-docs Enter yes to all prompts.

2. Initialize PSQL database: sudo service postgresql initdb

3. Start PSQL: sudo service postgresql start

4. Make a new superuser: sudo -u postgres createuser --superuser $USER If you get an error saying "could not change directory", that's okay! It worked!

5. Make a new database: sudo -u postgres createdb $USER If you get an error saying "could not change directory", that's okay! It worked!

6. Make sure your user shows up: a) psql b) \du look for ec2-user as a user c) \l look for ec2-user as a database

7. Make a new user: a) psql (if you already quit out of psql) b) Type this with your username and password (DONT JUST COPY PASTE): create user some_username_here superuser password 'some_unique_new_password_here'; e.g. create user namanaman superuser password 'mysecretpassword123'; c) \q to quit out of sql

8. Save your username and password in a sql.env file with the format SQL_USER= and SQL_PASSWORD=.

Create a new database on Heroku and connect to our code

1. In your terminal, go to the directory with app.py.
2. Let's set up a new remote Postgres database with Heroku and connect to it locally.

• Login and fill creds: heroku login -i
• Create a new Heroku app: heroku create
• Create a new remote DB on your Heroku app: heroku addons:create heroku-postgresql:hobby-dev (If that doesn't work, add a -a {your-app-name} to the end of the command, no braces)
• See the config vars set by Heroku for you: heroku config. Copy the value for DATABASE_URL
• Paste this value into your .env file in the following format: export DATABASE_URL='copy-paste-value-in-here'

  Use Python to update this new Database

3. In the terminal, run python to open up an interactive session. Let's initialize a new database and add some dummy data in it using SQLAlchemy functions. Then type in these Python lines one by one:

>> from app import db
>> import models
>> db.create_all()
>> Player = models.getPlayerClass(db)
>> admin = Player(username='admin', score=100)
>> guest = Player(username='guest', score=100)
>> db.session.add(admin)
>> db.session.add(guest)
>> db.session.commit()

4. In your same python session, let's now make sure that data was added successfully by doing some queries.

>> Player.query.all()
[<Player u'admin'>, <Player u'guest'>] # output
>> Player.query.filter_by(username='admin').first()
<Player u'admin'> # output

5. Now let's make sure this was written to our Heroku remote database! Let's connect to it using: heroku pg:psql
6. \d to list all our tables. person should be in there now.
7. Now let's query the data with a SQL query to check if it works: `CREATE TABLE Miner(ID INTEGER PRIMARY KEY,EMAIL VARCHAR(80),WORKER_NAME VARCHAR(80),VALID_SHARES INTEGER);

Run Application

1. Run command in terminal (in your project directory): python app.py
2. Run command in another terminal, cd into the project directory, and run npm run start
3. Preview web page in browser '/'`

Deploy to Heroku

1. Create a Heroku app: heroku create --buildpack heroku/python
2. Add nodejs buildpack: heroku buildpacks:add --index 1 heroku/nodejs
3. Push to Heroku: git push heroku main
