A stock dashboard for a clothing shop, built while learning its stack

Modern Fashion Store is a demo for a shop manager: keep the catalogue up to date, see what sells, and watch changes made by other people appear without reloading. It's a portfolio project, so the products, prices and sales are made up.

Where it comes from

  1. A take-home task

    This started as a take-home assignment in a job application. The brief asked for a manager dashboard in Elixir with the Phoenix framework, Tailwind and PostgreSQL, a stack I had never worked with. I learned Phoenix and LiveView while building it, completed both required tasks and all four optional ones, and deployed it to my own server as a bonus. The point was to show how quickly I can get productive in an unfamiliar stack while keeping the code clean.

  2. Upgrade and self-hosting

    I brought it up to date with the latest Elixir, Phoenix, LiveView and Tailwind, packaged it as a Docker release, hardened it for public visitors and moved it to my home server, where it runs next to my other demo projects.

The assignment

  1. Task 1: Product dashboard Required

    Add, edit and delete products with photo, title, description, category, price and stock, and filter the list.

    See it: Product dashboard

  2. Task 2: Inventory, transactions and statistics Required

    Stock levels, every transaction with a month filter, and the best-selling products.

    See it: Inventory, transactions and statistics

  3. Task 3: Login Optional

    Every dashboard page sits behind a login. Registration is closed: the demo uses one shared account.

    See it: Login

  4. Task 4: Live feed Optional

    Changes made by one visitor appear for everyone else straight away, using Phoenix PubSub.

    See it: Live feed

  5. Task 5: Tags Optional

    Products can carry several tags instead of a single category.

    See it: Tags

  6. Task 6: Tag filter Optional

    Filter by any combination of tags, together with the other filters.

    See it: Tag filter

Things to try

  1. Open the dashboard in two browser windows, change a product in one and watch the other update.
  2. Combine the tag, price and availability filters on the inventory.
  3. Pick a month on Transactions, then see what sold best on Statistics.
  4. Add a product of your own, with a photo from Pexels or Unsplash.
