littlejohn's Issues

PA Review: User Authentication

User Auth

Functionality

  • The main button with logo should link to /
  • Has working demo login
  • Smooth, bug free navigation

Before Login

  • The /login page should not display a link to Log In. Same for /signup
  • Going to a random route /#/oweiniouewbrviuwebv should redirect or display a 404 page
  • Errors should display for both /signup and /login.
  • Errors should clear when moving between /signup and /login.
  • Can sign up a user
  • Can sign in as a user
  • Can log out a user
  • Can't sign up with the same username/email
  • Pressing enter after filling out the session form should use the form data, not the demo user

After Login

  • Should not be able to visit /login or /signup
  • Should be able to refresh the page and still be logged in

Style

  • The site should look exactly like the actual site
  • All relevant elements should have cursor: pointer on hover
  • When errors are displayed, most elements should not move around the page (particularly input boxes)
  • Remove Redux logger and all console.log()'s from production

Seeds

  • Adequate and appropriate seeds

Design Docs

Wiki Page Home

  • Is the first page you see upon entering the wiki
  • Contains a welcome message
  • Contains a link/placeholder for a link to the live page
  • All links in the right sidebar should contain each wiki page and link to the correct page
  • Correctly formatted
    • each wiki page is listed in bullet points
    • all links route the correct page

Comments


MVP List

  • Should have 7 MVPs.
    • 3 of those are User Auth, Heroku, and Production README.
    • The other 4 are from the MVP List or they have clarified them with you
  • Contains a description sentence of the app
  • Includes two to three detailed bullets on functionality and presentation of feature
  • At least one CRUD feature, which states what CRUD operations are planned (creation, reading, updating, deletion)
  • Estimates how long it will take the code each MVP
  • Correctly formatted
    • MVPs are listed in an ordered list
    • Each MVP is broken down into bullet points

Comments


Database Schema

  • Contains correct datatypes
  • Contains appropriate constraints/details
    • primary key
    • not null
    • unique
    • indexed
    • foreign key
  • Contains bullet points after the table that state which foreign keys will reference to which table, or references to the associations which will be made
    • foreign key and table name are lowercased, snake_cased and back_ticked
  • Correctly formatted
    • schema is written in a table format
    • the table's name are lowercased, snake_cased and back_ticked
    • the table header column names are bolded
    • columns names are lowercased and snaked_cased and back_ticked

Comments


Sample State

  • State shape is flat!
  • State's keys are camelCased
  • All keys within the values in the state are accessible in the schema
  • Correctly formatted
    • Sample state is rendered with triple backticks, and the language ```javascript...```). This will display the state as a code block instead of a giant line of text
    • Top level slices
      • entities
      • session
      • errors (here or in ui)
      • ui (if needed)
    • Should NOT have nested slices, aka comments inside of posts
      • Some info from other tables is ok, for instance:
        • the author username and imageurl for a post. basically any info that the user can't change
        • like count and a boolean on whether the user likes the post instead of a likes slice

Comments


Backend Routes

  • Contains the following sections: HTML, API Endpoints(Backend)
  • Each route has a description
  • API Endpoint routes contains wildcard variables written in snake_case
  • Routes does not contain superfluous routes
  • Have API routes that will allow the front end to get all info it needs and does not have unneeded routes:
    • probably doesn't need a GET likes api endpoint because that info comes through the post show

Comments


Frontend Routes

  • Frontend routes contains wildcard variables written in camelCase
  • Correctly formatted
    • Routes are displayed with inline coding text (backticks)
