This is my solution for the Would Your Rather project for Udacity's React Nanodegree. It is based on the project starter code, which begins with nothing but a JS file with the app's initial state. It is meant to be an example site that provides a basic demonstration of React and Redux.
You will notice various quirks, such as how all the authentication is on the frontend, and the application state is always reset when you reload the page or directly visit a URL from the browser, as opposed to navigating through the site via the links. This is all due to how the Redux store is not persistent, as that requirement was not in the scope for this project. I might come back and revamp this project in the future, however.
When at the login screen, choose a user from the dropdown and click the Login button. You will then see the Dashboard as that user. You can view other users questions that you've answered or not yet answered by clicking the tabs. For answered, questions, you will be shown the overall results among users. For unanswered questions, you will be shown a form to submit your answer. The questions are all in the form of "Would you rather..." (e.g. "learn Swift or learn Javascript?").
You can also view the Leaderboards which just update as you answer and create questions. You can also logout.
Again, note that since the Redux store data does not persist, everything will be reset to the initial data if you reload or type in a URL to visit.
Take note of the following available environment variables when building the container. You should only need to use
GIT_REMOTE when doing volume-based deployment for production. The other settings are optional:
GIT_REMOTE- Set this to the URL of the git repo that the project is in for volume-based deployment. The presence of this value will trigger production deploymentGIT_DOMAIN- The domain of theGIT_REMOTE, which is needed to allow SSH connections to the endpoint without prompting for user input. Default:github.comPORT- The port that the node server will run on. Default:8003DEPLOY_USER- The user in the container that will manage deployment. Default:nodeDEPLOY_USER_HOME- TheDEPLOY_USER's home directory. Default:/home/$DEPLOY_USERSSHDIR- The directory where the SSH key pair from the project.sshdirectory is copied to before they are later copied to theDEPLOY_USER's.ssh. Default:/root/Downloads/sshWORKDIR- Where the project will be loaded. Default:$DEPLOY_USER_HOME/would-you-rather
For Docker deployment, first build the image:
docker build --tag=enderandpeter/would-you-rather .
Then either set a GIT_REMOTE for volume-based production deployment or omit this value for bind-mounted dev deployment:
docker run -p 8003:8003 -e PORT=8003 -v would-you-rather:/home/node/would-you-rather --name=would-you-rather -e GIT_REMOTE=git@github.com:enderandpeter/reactnd-project-would-you-rather-starter.git --restart=always -it enderandpeter/would-you-rather
docker run -p 8003:8003 -e PORT=8003 -v /path/to/would-you-rather:/home/node/would-you-rather --name=would-you-rather --restart=always -it enderandpeter/would-you-rather
Otherwise, you know the drill. Either run npm install && npm start or yarn install && yarn start if you're cool like me.
This is the starter code for the final assessment project for Udacity's React & Redux course.
The _DATA.js file represents a fake database and methods that let you access the data. The only thing you need to edit in the _DATA.js file is the value of avatarURL. Each user should have an avatar, so you’ll need to add the path to each user’s avatar.
Using the provided starter code, you'll build a React/Redux front end for the application. We recommend using the Create React App to bootstrap the project.
There are two types of objects stored in our database:
- Users
- Questions
Users include:
| Attribute | Type | Description |
|---|---|---|
| id | String | The user’s unique identifier |
| name | String | The user’s first name and last name |
| avatarURL | String | The path to the image file |
| questions | Array | A list of ids of the polling questions this user created |
| answers | Object | The object's keys are the ids of each question this user answered. The value of each key is the answer the user selected. It can be either 'optionOne' or 'optionTwo' since each question has two options. |
Questions include:
| Attribute | Type | Description |
|---|---|---|
| id | String | The question’s unique identifier |
| author | String | The author’s unique identifier |
| timestamp | String | The time when the question was created |
| optionOne | Object | The first voting option |
| optionTwo | Object | The second voting option |
Voting options are attached to questions. They include:
| Attribute | Type | Description |
|---|---|---|
| votes | Array | A list that contains the id of each user who voted for that option |
| text | String | The text of the option |
Your code will talk to the database via 4 methods:
_getUsers()_getQuestions()_saveQuestion(question)_saveQuestionAnswer(object)
_getUsers()Method
Description: Get all of the existing users from the database.
Return Value: Object where the key is the user’s id and the value is the user object.
_getQuestions()Method
Description: Get all of the existing questions from the database.
Return Value: Object where the key is the question’s id and the value is the question object.
_saveQuestion(question)Method
Description: Save the polling question in the database.
Parameters: Object that includes the following properties: author, optionOneText, and optionTwoText. More details about these properties:
| Attribute | Type | Description |
|---|---|---|
| author | String | The id of the user who posted the question |
| optionOneText | String | The text of the first option |
| optionTwoText | String | The text of the second option |
Return Value: An object that has the following properties: id, author, optionOne, optionTwo, timestamp. More details about these properties:
| Attribute | Type | Description |
|---|---|---|
| id | String | The id of the question that was posted |
| author | String | The id of the user who posted the question |
| optionOne | Object | The object has a text property and a votes property, which stores an array of the ids of the users who voted for that option |
| optionTwo | Object | The object has a text property and a votes property, which stores an array of the ids of the users who voted for that option |
| timestamp | String | The time when the question was created |
_saveQuestionAnswer(object)Method
Description: Save the answer to a particular polling question in the database.
Parameters: Object that contains the following properties: authedUser, qid, and answer. More details about these properties:
| Attribute | Type | Description |
|---|---|---|
| authedUser | String | The id of the user who answered the question |
| qid | String | The id of the question that was answered |
| answer | String | The option the user selected. The value should be either "optionOne" or "optionTwo" |
This repository is the starter code for all Udacity students. Therefore, we most likely will not accept pull requests. For details, check out CONTRIBUTING.md.
This project was bootstrapped with Create React App.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
You can learn more in the Create React App documentation.
