- Clone and download the project
- Install all project dependencies with
npm install - Start the development server with
npm start - Open http://localhost:3000 to view it in the browser.
- Run the tests with
npm test - Build the project with
npm run build
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may 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.
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:

| id | String | The user’s unique identifier |
| password | String | The user’s password in order to log in the application |
| 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 |

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 |
