NPM Packages is not up to date

[ThibaudTeachup]

Hello,

I recently dowloaded your package through NPM and it looks like the last changes you made are not up to date.
For example, the center option for the grid is not implemented.

Could you please update your NPM package so that everyone can access lastest features ?

Thanks !
