I looked at the angular-ui modules because I need to implement a grid.
I saw that there is the stable ng-grid and the unstable version ui-grid.
Which version should I use?
Are they very different or hard to switch?
The github repo says that all development will happen on ui-grid (ng-grid 3). That means ng-grid has become a legacy grid. ui-grid is stable enough to use in my opinion and the only reason to use ng-grid is if you already started with it. New projects would be better off using ui-grid. They also claim that the performance of ui-grid is better than that of ng-grid though I haven't tested that.
UPDATE:
A stable version of UI Grid 3 is out which means that it can be used in production applications. On their documentation site, they have a guide on how to upgrade from legacy ng-grid. See Tutorial: 099 Upgrading
It's the same project. ng-grid is older (version 2.x), UI Grid is newer (version 3.x) but not officially relased yet (currently in release candidate status). They're very similar, compare the tutorials for v2 (ng-grid) and v3 (UI Grid).
Edit (Nov 12 2014): One major feature from v2 that is still missing in v3 is grouping (github issue). If that's something you can't do without stick with v2 for now.
ui-grid is replacing ng-grid, and support for ng-grid is getting thin as most of the original (2.x) contributors are no longer active, the remaining contributors are almost exclusively working on 3.0 only.
So, I would use ng-grid if:
- you are already using it and don't have any pressing issues that would force an upgrade
- you really need a stable and well tested product
I would use ui-grid if:
- you are starting a new project now, and not intending to be in production for a few months
- you need a feature that ui-grid offers and ng-grid doesn't (such as exporting, importing, state saving), or specific functions that ui-grid offers
- you plan on extensively customising or pushing the limits of the functionality - ui-grid is more customisable and more supportable
- you have tried it and it does everything you want
- you don't need IE support earlier than IE9 (and mostly IE10 and up only)
In general, I'd lean towards ui-grid unless you can't use it for some reason.
Note also that grouping was recently released in alpha.
EDIT: We've also recently noticed that Amazon Web Services are using ui-grid in their console in a couple of places....so I guess that partly answers the question as to whether it's ready for production usage.
