Implementing a BlocNote with Jodit

artydev profile image artydev ・3 min read

Here is the first draft of a personnal project.

It's implemented using Mithril, but you can use whatever frontend library you want (uhtml,react,vue...jquery...).

The main point is that it uses the Meiosis pattern and BrowserFS for localStorage.

For the css part I use w3css.

Actual features :

  • You can save a note
  • You can display the notes list
  • You can edit a note

more to come....

You can test it here BN
