About The Project

The project is a clean monorepo. The backend serves the frontend, frontend calls the backend, backend writes to db, so on. They are standalone apps to the extent that their variables do not depend on each other. (Right now, they do).

It is written with a Flask/Python restful backend API, a database driver to MongoDB Atlas, and a React/Typescript CRA frontend.

Scripts in root package.json implement Yarn workspaces only to run development-specific scripts from root assuming all backend/frontend-specific configs have been set up.

On the whole monorepo thing

> **Note:** Scripts in root `package.json` implement Yarn workspaces only to run development-specific scripts from root assuming all backend/frontend-specific configs have been set up. Running `yarn` from root has not yet been tested. For the meantime, `cd`ing to frontend and installing the React-App is the minimal reliable option to develop the app with a fixed and unchanging backend API. The backend `package.json` is solely for running python scripts from root. Backend API and data layer are superuser-specific given the production deployment, although local env variables are described in case anyone wants to locally serve a Mongo Atlas connection string from scratch. To be updated.

Wireframes

Concept

The project can be understood as a library of user-created Albums or Playlists with the ability to organize, query and add items or tracks to those collections

Code Snippet (item)

Collection (playlist)

Search (filter)

Design

Accordion Cards

A consistent border is applied to all nodes with dynamic content. These discrete borders are designed to convey the scale of snippet item relative to a collection. These containers only vary in spacing and height and are responsible for visually conveying open and closed states of snippets in collections of snippets.

Theme

Chakra-UI's ThemeProvider wraps the app in order to pass styles down the component tree. See Chakra-UI.

Colors

The app features two sets of neutral tones for light mode and dark mode. Tones are applied to backgrounds while borders are rendered to highlight items and convey feedback. Tones are minimally set to three values within #fafafa and #010f08 in order to reserve state-changes to border sizes and scales.

Features

Existing Features

User Registration

The website features the ability to sign up, sign in and sign out in order to conditionally access existing features. A user is based on the user model, which requires username, email and password for new users and only the latter two for existing users. For security, only usernames are stored in local storage while tokens are stored in memory. To ensure sign out across multiple open windows, a logout event triggers a storage event listener which clears tokens and usernames in the memory of the current window.
Actions:
Ability to create an account. (any User)
Ability to sign in to an account. (Registered Owner)
Ability to sign out of an account. (Registed Owner)

Code Snippets

The website features the ability to create, update and delete a code snippet. A snippet is based on the snippet model and each field is represented as either a form field or a section in an article depending on whether a code snippet is being edited or being featured.
Actions:
Ability to create, edit and delete a code snippet. (Registered Owner)
Ability to fave and unfave a code snippet. (Registered User)

Collections

The website features the ability to group any and all existing code snippets into named collections aka cheat sheets. A collection is based on the collection model, which is a name and a list of snippets. Each field is represented as either a form field or a header followed by a ul depending on whether a collection is in edit or display mode.
Actions:
Ability to create, edit and delete a named collection. (Registered Owner)
Ability to add and remove snippets to/from a collection. (Registered Owner)

Search

search_text indices are attached to the title and description fields of the snippets cluster. The frontend UI of the search feature is designed to return snippet cards that match a query. Additionally, the ability to query by tags and language is enabled by filtering these existing fields in the database.
Actions:
Ability to search code snippets created by others. (any User)
Ability to filter snippets by language. (any User)
Ability to filter snippets by tags. (any User)
Ability to copy snippets to the clipboard. (any User)
Ability to fave or unfave snippet results from search. (Registered User)
Ability to perform crud operations on snippet results from search. (Registered Owner)

Features Left to Implement

Add query params to all resources
Extend query parser to parse more than one query at a time
Optimize performance by dereferencing database records
User profile page
Ability to add friends
Ability to share snippets

Programs and Software

VSCode: Visual Studiio Code 2020.3.2 by Microsoft is the IDE used to locally construct the project
Git: Git is used as the version control system and is utilized via the WebStorm terminal to commit to Git and push to GitHub.
GitHub: GitHub is used to store the project's code and directory upon concurrent pushes via Git.
Adobe InDesign: Adobe InDesign is used to mock wireframes.

Notes

Styles are written in-component and merge both Chakra-format and Framer-motion-format to achieve desired UI results. This is done by declaring motion boxes in Typescript to accespt Motion-Framer's HTML style props and Chakra's.
Pagination is only for search endpoint.
Access Token is stored in memory. Only usernames are stored in local storage, along with storage event listener for key app-logout which is triggered on logout and ensures all windows are logged out while the tokens are stored in a token blocklist cluster.

Lighthouse via Vercel is used to test performace, which produces unique results on every git push. lighthouse-badges is used to generate new badges for every deployment by installing npm i -g lighthouse-badges and pushing the new hashed url to the array of urls:
```
lighthouse-badges 
-o docs/badges -r 
-u https://cheathub.vercel.app/ [... all other urls]
                   
# Output to docs/badges
# Badges will contain the respective
  average score(s) of all the urls 
  supplied, combined
```
Lighthouse's metrics, namely Accessibility and Performance generate specific flags on each audit. Adjustments are made on each push that specifically address any issues.

Accessibility Testing

ChromeVox Extension was used to ensure that screen-reader accessibility standards are met. This was done by walking through the entire project with the screen-reader plugin enabled. Various adjustments were made following these tests. Notably, the tab-index order of nav elements, and changing refining HTML5 semantic elements for role clarity.

Browser Testing

Throughout the development of the project, in-browser dev tools were used to test for consistency across browsers. The browsers themselves were equally used for general use-case testing. The following browsers' per-device applications were accessed with an iPhone 11 Pro, MacBook Pro 15" and iPad Pro 12.9":
Chrome Version: 83
Firefox 82
Opera 72
Safari 14
