The challenge
Any FiveM script that wants to sell widely has to work on ESX, QBCore and QBox, the three big frameworks servers run on. Without a shared foundation, that means writing the code for players, items, money and notifications three times in every script. Three times the work, three times the bugs, three times the upkeep.
What we built
The shared foundation we wished existed, released for free:
- One set of building blocks that works on all three frameworks, so a script built with fmLib runs on every server unchanged
- Ready-made connections to popular scripts that most servers already use
- Extra tools that almost every script needs, for the game logic as well as the in-game screens
- Public documentation on our documentation site
Our own catalog of more than 150 scripts is built on it, so fmLib is tested every day on real servers instead of being a demo nobody uses.
The result
fmLib has been downloaded more than 23,000 times, carries the framework support for every script we sell and is free for any FiveM developer to build on. Doing that work once, and properly, is a big part of why our scripts install in minutes instead of days.
