# Take Home Interview Project
This is my solution to a past interview challenge from [LCOGT](https://github.com/LCOGT).

## Directions
Create a web application where a user can view and add planets to a database.
### Estimated time for completion:
2-4 Hours
### Instructions
Use whatever programming language/framework that is most comfortable to you. The deliverable
product should be the sourcecode to a runnable web application with all the requirements met.
The database should be blank: you do not need to provide any data with the deliverable.
Place any special setup instructions in a file called SETUP.
Using github, you should fork this repository ([Github: how to fork a repository](https://help.github.com/articles/fork-a-repo/)) and add the code you have written to it. When you are done, open a pull request. It will then be reviewed.
## Requirements
#### The homepage
The homepage should contain a list or table of the planets that have been added to the database
along with their name, size, distance and ordinality.
For example:
Ordinality Name Size Distance
1 Mercury 0.05 0.34
2 Venus 0.08 0.72
The name of the object should link to that object's detail page.
#### The input form
A simple form for adding a planet to the database. The form should have 5 inputs:
Name, Size (in Earth Masses), Distance (from the sun, In Astronomical Units), Ordinality (Mercury: 1, Neptune: 8)
and Description.
For example:
____ ____ ____ ____
Name |____| Size |____| Distance |____| Ordinality |____|
__________________________________
Description: | |
| |
|__________________________________|
______
|SUBMIT|
Name and ordinality should be unique. Size, Ordinality and Distance should be restricted to numerical input.
#### The detail page
The detail page should simply display all the available information about the planet.
For example:
Mars
Mars is the dry and inhospitable 4th planet from the Sun. It is here that Matt Damon
grew potatoes using his own poop.
Ordinality: 4
Size: 0.107 Earth Masses
Distance: 1.41 AU
### Hints
1. Use sqlite/memory/flat files instead of something like mysql or postgresql to store data. This will make the setup much less complicated.
2. Don't worry about styling: the pages don't have to be pretty, just functional.
### Bonus
Provide an application that can serve multiple users, with a backend component as opposed to a pure client side application.
## My Process
## Built With
- express
- ejs
- sqlite3
## How to Use
To clone and run this application, you'll need [Git](https://git-scm.com) and [Node.js](https://nodejs.org/en/download/) (which comes with [npm](http://npmjs.com)) installed on your computer. From your command line:
```bash
# Clone this repository
$ git clone https://jdegand.github.io/LCOGT-takehomeinterview
# Install dependencies
cd LCOGT-takehomeinterview
$ npm install
# run server and go to http://localhost:3000
$ npm start
```
## Thoughts
- Used pattern attribute with regular expression for form validation
- Less documentation and good examples to follow when working with SQLite and Express
