FlexiBook
by Coishi-C261
FlexiBook lets authors build custom in-game books from a web editor, with images, fonts, colors and clickable links.
What it does
A book is written in a browser-based editor that ships as a packaged Electron app, so the book is laid out before it reaches the game. Layout is recalculated when the language changes, and pagination runs automatically. Cached layout results are reused to reduce load time. Files cover 1.20.1, 1.21.1, 1.21.4, 1.21.11, 26.1, 26.1.1, 26.1.2 and 26.2, and the mod runs on client and server, so both sides need it. It is open source under the GNU General Public License v3.0 or later.
