Foodbarrio ReactNative & GraphQL test

For reference, see original readMe below.

App setup

Tools you have to install in advance on your machine to run this app: PostgreSQL, an iOS or Android emulator, Node.js, npm, and the expo CLI.

Steps to install

1. Open your favorite Postgres client and create a new database with a name of your choosing (eg. foodbarrio_challenge_db)
2. Create a file named .env in the project root folder and complete it with your Postgres credentials, eg.:

PGDATABASE=foodbarrio_challenge_db
PGHOST=localhost
PGPORT=5432
PGUSER=postgres
PGPASSWORD=<your_pg_pwd>

3. in project root folder, npm install to install server node modules, then launch npm run db-setup to build the database and fill it in with some test data (knex seeds)
4. cd client && npm install to install client node modules

Steps to launch

Once the installation is complete, in project root folder run npm start to run the server (on default port 4000), then cd client && expo start to start the expo CLI. From there you can choose whichever device you prefer to run the app.

Note that if you're running the app on a different machine (such as a physical device) you won't be able to connect to the local database, in this case I suggest using a service like ngrok to create a safe public tunnel to your localhost and then set the Apollo client URI in App.js.

The goal is to implement a small Post/Comments app using GraphQL API and React Native.

Screens

The app will have three screens.

• Login
• List of posts
• Create/Edit post
• Post details

Navigation

• The user inserts his/her username in the "Login" screen to enter the app. If the inserted username doesn't exists, it will be created.
• After the login the user is moved to the "List of posts" screen where he/she can scroll the list of available posts (each post indicating when it has been created, the number of comments and the number of likes received).
• From the "List of posts" screen the user can navigate back to the "Login" screen (logout) or to the "Post details" screen by tapping on one post.
• In the "Post details" screen the user can scroll the list of available comments (each comment indicating when it has been created and the number of likes received).
• From the "Post details" screen the user can navigate back to the "Login" screen (logout) or to the "List of posts" screen.

Use cases

Must have

As a user I can

• enter the app with a username
• see all available posts
• create new posts
• edit/delete my posts
• like and unlike my or other posts
• create new comments on my or other posts
• edit/delete my comments on posts
• like and unlike my or other comments

As a user I can't

• delete or edit posts of other users
• delete or edit comments of other users

Desiderable

As a user I can

• see new posts from other users without refreshing the "List of posts" screen
• see new comments from other users without refreshing the "Post Details" screen
• see new likes from other users without refresing the "Post Details"

Nive to have

As a user I can

• search content in the posts

Data structure

This is only an example of a possible data structure that can be used

User

• username

Posts

• username of the author
• title
• content
• createdAt

Comments

• parentPost
• username of the author
• title
• content
• createdAt

Likes

• parentPost or parentComment
• username of the author
• createdAt

Tools that you have to use

Must have

• NodeJS and NPM
• Apollo Server (GraphQL)
• Apollo Client
• React Navigation

Desiderable

• Express
• Knex (with migrations)
• PostgreSQL

Nice to have

• Expo

Documentation

All steps to install, maintain and run the app must be documented

NOTE

The submission will be DISCARDED if it DOES NOT provide instructions on how to install and configure the test environment (server, app, database,...).
