On a Debian or an Ubuntu system there is a file called /var/lib/dpkg/status that holds information about software packages that the system knows about. Write a small program that exposes some key information about currently installed packages via a html interface. The program should listen to http requests on port 8080 on localhost and provide the following features:

• The index page lists installed packages alphabetically with package names as links.
• When following each link, you arrive at an information about a single package. The following information should be included:  - Name  - Description  - The names of the packages the current package depends on (skip version numbers)  - The names of the packages that depend on the current package
• The dependencies and reverse dependencies should be clickable and the user can navigate the package structure by clicking from package to package.

Some things to keep in mind:

• Minimize the use of external dependencies.  - The goal of the assignment is to view how you solve the problems with the programming language, not how well you use package managers :)
• The main design goal of this program is maintainability.
• Only look at the Depends field. Ignore other fields that works kind of similarly, such as Suggests and Recommends.
• Sometimes there are alternates in a dependency list, separated by the pipe character (|). When rendering such dependencies, render any alternative that maps to a package name that have an entry in the status file as a link and just print the name of the package name for other packages.
• The section Syntax of control files of the Debian Policy Manual applies to the input data.
• A sample input file from https://gist.github.com/lauripiispanen/29735158335170c27297422a22b48caa

Running

1. Make sure you're using node > 8, or if using nvmrc, you can simply run nvm use which will automaticall install required version. Also, if not using yarn => now it's a great time to start ;)

2. In the project directory, run:

yarn install

to install required depencies.

PORT=8080 yarn start

Runs the app in the development mode.
Open http://localhost:8080 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

yarn run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
