jExcel – the JavaScript spreadsheet

Tables on the web are always challenging. Whether you do them by hand, or with the help of a framework or library, they often carry a lot of complexity, performance costs, and compatibility issues.

Recently I came across jExcel, which seems to be quite powerful, with lots of advanced features, and, at the same time, rather simple to use. The recent release of version 3, brings even more features and improves on the existing ones:

  • Drag and drop columns
  • Resizable rows
  • Merge columns
  • Search
  • Pagination
  • Lazy loading
  • Full screen flag
  • Image upload
  • Native color picker
  • Better mobile compatibility
  • Better nested headers compatibily
  • Amazing keyboard navegation support
  • Better hidden column management
  • Great data picker: dropdown, autocomplete, multiple, group options and icons
  • Importing from XSLX (experimental)

Have a look at some of the usage examples too.

Experiments: Limited Web Experience

Smashing Magazine runs a series of articles by Chris Ashton, a senior software engineer at BBC, in which he experiences the web for one day with a selected limitation. So far he has tried the following:

eDEX-UI – a sci-fi terminal

eDEX-UI is a science fiction terminal that runs on most operating systems. It was heavily inspired by the user interfaces in sci-fi movies, like TRON, Minority Report, and others. While it’s not very practical for the day-to-day use for anyone heavily using command line, it’s a lot of fun to run when there are non-technical people around, staring at your screen.

The installation is pretty simple:

git clone https://github.com/GitSquared/edex-ui.git
cd edex-ui
npm run install-linux
npm start

I think it works even better with a large touch screen, but I don’t have one around to try it on.

laravolt/avatar – plug-n-play PHP library for quick dynamic avatars


laravolt/avatar is a PHP library that helps to avoid those old and boring anonymous face pictures for users who haven’t uploaded or configured their avatar in your application.  With library you can use any string – name, email, initials, or anything else you fancy – to generate a dynamic avatar with random color and letters.

Design for Blockchain


Design for Blockchain” is a collection of articles about user interface and user experience design for blockchain and cryptocurrency projects and tools.  Blockchain, due to its nature, is quite a technical subject, so making it friendly for non-technical users is a challenge.  These articles are exploring the domain problem.
