Project Euler Watcher

This repository consist of a Python script and a React application that work together to solve the problem of not being able to sort or search through the problems on Project Euler easily.

Genrelly, this is a result of my own frustration from some of the problems mentioned above.

Building

First thing first, clone the repository:

$ git clone https://github.com/lubeskih/project-euler-watcher.git

Python script

The Python script (located under scripts/scrape/) is a scraper that extracts the problems (the problems include the archive page, as well as the most recent ones) from the Project Euler archive page and dumps them into a JSON file.

To start the script, I would recommend first installing Virtualenv, and then:

virtualenv venv --python=python3

pip install -r requirements.txt --user

and to run it:

python scrape.py

The JSON file will be located in the same directory, and the dump should look like this:

[
  {stamp: "Sat, Feb 29, 2020 at 10:45 PM", records: 600 },  # METADATA
  [{ id: 1, title: "example title" }, {...}],               # ARCHIVE
  [{ id: 5, title: "another example title" }, {...}]        # RECENT PROBLEMS
]

In order for this to work locally, move the JSON file into the public directory.

React App

In the root directory, to install the required packages - run:

yarn

To start the application (defaults to port 3000), run:

yarn start

Or to build it:

yarn build

NOTE: After building, you may want to use a HTTP server to serve the builded application, for example (inside the build directory):

python3 -m http.server
