myForms

About

myForms is a progressive web application for creating surveys / tests, administrating them through shareable links, and viewing the results once submissions are received. This application follows the specifications required by the Engineering Design VI course (SSW-322 at Stevens Institute of Technology).

The running application can be found at: https://myforms.herokuapp.com

Technology Stack

The technology stack for myForms can be classified into three distinct parts:

Client

• Typescript for primary language
• React for view framework
• Styled-Components for styling views
• Redux for state managment
• Redux-Observable for handling side effects
• Redux-First Router for application routing

Server

• Typescript for primary language
• Express for web framework
• JSON Web Tokens and cookies for authentication

Database

• MongoDB for storing data

To help maintain a uniform runtime environment and relieve possible dependency issues, the entire stack is set up to run in Docker via Docker Compose. The stack is made up of two Docker containers:

• myforms_app : Image based on node-9.5-alpine where the React client and Node server will be run.
• mongo:3.6.2-jessie : Image where the MongoDB instance will be run. All data will be persisted /data/ of this project folder.

Some Terminology

Some terms or conventions in the code base may be unfamiliar so I'll try to define some of them here.

Reducers

Reducers are pure functions that take an action and the current Redux state object and then return a new state object. Reducers can be composed together and a composition of all the application's reducers is called the root reducer. In this project, files named reducer.ts contain a reducer and definitions for the actions that the reducer acts on. More can be read about reducers in the docs for Redux.

Epics

Epics are the means by which asynchronous Redux actions are performed. In essence, they take in actions, perform side effects, and return new actions as a result. More can read about them in the docs for Redux-Observable.

Selectors

Selectors are memoized functions that take the global Redux state as an argument and return some value computed from the state. They can be read about in more detail at Reselect's GitHub Repo.

How to Run

Development

• Install Docker on your machine
• Ensure that both docker and docker-compose work in your terminal
• Install Node on your machine
• Pull down a copy of this repository
• Run cd my-forms (Or wherever this project is stored)
• Run npm install to install dependencies
• Run npm run docker to start dev Docker container
• Application will now be running on localhost:3000
• As you edit source files, webpack will perform hot module replacements from the Docker container

Production

• Install Docker on your machine
• Ensure that both docker and docker-compose work in your terminal
• Pull down a copy of this repository
• Run cd my-forms (Or wherever this project is stored)
• Run docker-compose up to start the application on localhost:3000
