About

This is a frontend project assessment I did with Hatchways.io which involved completing three tickets:

• A Bugfix
• UI Redesign
• New Feature

You can see my progress and feedback by looking at the closed pull requests.

Messenger

A one-to-one realtime chat app.

Local Setup

Create the PostgreSQL database (these instructions may need to be adapted for your operating system):

psql
CREATE DATABASE messenger;
\q

Alternatively, if you have docker installed, you can use it to spawn a postgres instance on your machine:

docker run -it -p 5432:5432 -e POSTGRES_DB=<database-name> -e POSTGRES_USER=<database-username> -e POSTGRES_PASSWORD=<database-password> postgres -c log_statement=all

Update db.js to connect with your local PostgreSQL set up. The Sequelize documentation can help with this.

Create a .env file in the server directory and add your session secret (this can be any string):

SESSION_SECRET = "your session secret"

In the server folder, install dependencies and then seed the database:

cd server
npm install
npm run seed

In the client folder, install dependencies:

cd client
npm install

Running the Application Locally

In one terminal, start the front end:

cd client
npm start

In a separate terminal, start the back end:

cd server
npm run dev

How to Run E2E Tests

1. Seed the database with npm run seed in server directory.
2. Start the backend server with npm run dev in server directory.
3. Start the frontend server with npm start in client directory.
4. Open Cypress dashboard with npx cypress open in client directory.
5. Click on the test suite to run (e.g. auth.spec.js).

Notes

• You need to seed the database before each run. Because E2E test cases writes data to the actual database, re-seeding is necessary to assure consistent test results.
• The E2E tests are not comprehensive. There is a test for the authentication pages that should pass with the starting code, and some tests for some of the functionality for some of the tickets you will be assigned.
• When you push your changes to GitHub, E2E tests are automatically executed on GitHub Actions. You can find test results under Pull request > Checks > test > Cypress (see screenshots below).
