This is a simple website that handles sorting a list of Posts title.

It utilises the LexoRank, a lexical (alphanumerical) ranking system for sorting by drag and drop.

It also renders 500 post title items using react-window to reduce render loads.

• Development

Traditional numerical ranking system are limited by insufficient space allocations. The challenge in drag and drop is the probability of reaching these limits are high.

A lexical ranking system solves this issue by having an abundant of space allocations where in production should be accomodated with rebalancing to prevent performance drawbacks.

• Node v20 is required.
• Docker and Makefile is also being used.

Run the following when setting up the project for the first time:

make init

• This will create a mongoDB container using docker make db-init.
• Install server npm packages cd server && npm install.
• Seed database with posts title in Posts collection. make db-seed.

Start server in development mode: make server

Install dependencies in client: cd client && npm run install

Start client in development mode:

• This will also automatically generate the query typings for graphql make client-generate.
