Commits.to — a.k.a. The I-Will System

Start with the Functional Spec which also gives the backstory for this project.

Development Setup

Follow the steps below. Please make a pull request if any of this isn't super straightforward or you need to do additional steps to get up and running!

Set Up The Database

Install Postgres

Environment	Command
macOS	brew install postgresql
Linux	sudo apt install postgresql

Start Postgres

macOS

Start it with running either brew services start postgresql to have it as a background service that will restart if you reboot or pg_ctl -D /usr/local/var/postgres start to start it just once.

Ubuntu

Start it with the command sudo service postgresql start to have it run as a background service that will restart if you reboot or sudo -u postgres /usr/lib/postgresql/10/bin/pg_ctl -D /var/lib/postgresql/10/main -l logfile start which runs the script as the automatically created PostgreSQL user account to start it just once.

Confirm that postgresql is running on localhost:5432. If you run pg_isready you should see /tmp:5432 - accepting connections.

Create Database

Run the following to create a user and a database. If prompted for a password, use the password iwill.

macOS

createuser -P iwill
createdb -O iwill commitsto

Ubuntu

sudo -u postgres createuser -P iwill
sudo -u postgres createdb -O iwill commitsto

Install Dependencies

2.1 Install Node 8.x LTS with the binary or installer or by using a package manager.

Set Up Hosts File For Subdomains

Add the following line to /etc/hosts with whatever subdomains you want to be available:

127.0.0.1	commits-to.js www.commits-to.js alice.commits-to.js bob.commits-to.js

You should also add any subdomain you will to use to create test commits to the list USERS in the file db/seed.js , e.g.:

const USERS = [
  /* testing */
  'alice', 'bob', 'carol', 'deb', 'my_new_username',
]

Make sure to re-seed the database if you make changes here.

Create Environment File

Create a .env file in the root of the project directory with the following contents, replacing <yourname> with your name:

ENV_NAME=<yourname>-dev
PORT=8080
APP_DOMAIN=commits-to.js:8080
DATABASE_URL=postgres://iwill:iwill@localhost:5432/commitsto

# Optional
MAILGUN_KEY=
MAILGUN_DOMAIN=
MAILGUN_TO=
MAILGUN_FROM=

Run The Application

• If you are running the app for the first time, or have recently pulled changes, you should run npm install
• Start the development server with npm run start:dev

Try The App

Just navigate to commits-to.js:8080 (the ENV_DOMAIN - must contain the PORT)

Seed The Database

Browse (or send a GET request) to http://commits-to.js:8080/reset which drops all tables and inserts seed data from the data/ folder

Troubleshooting

If you have problems connecting to the application via your browser, check that you have made the necessary changes to the /etc/hosts file for the subdomain you are using.
You may also need to flush the DNS cache to ensure those changes are recognized.

Ubuntu

On Ubuntu, you can use the name service cache daemon (nscd) to flush the DNS cache.

sudo apt-get install nscd
sudo service nscd restart

Mac

On MacOS, the command to flush the DNS cache will depend on your exact OS level. See How To Clear Your DNS Cache for detailed recommendations by OS version.

Testing

Run Mocha tests with npm test.

Writing tests

We're using the Chai assertion library and Sinon for spying/stubbing. You can run tests in watch mode to get results nearly instantly on save with npm run test:watch

Structuring tests

The structure and naming inside the test/ folder should mirror the root structure and file names. Writing code with well-contained classes or functions will be the most straightforward to unit test.
