Previously when provisioning list, libraries, site columns, content types, list definitions etc in SharePoint I typically used SharePoint features, deployed via a WSP - or used PowerShell scripts. This meant I had a package that could be deployed to DEV / TEST / PROD.
I'm working with SharePoint within Office 365 and unsure on the best way to provision lists / libraries / features within SharePoint.
Options:
No Code Sandboxed Solutions Trying to avoid using these as the information from Microsoft on whether they are deprecated is flaky - however sandboxed solutions would allow me to deploy features with list definitions etc. I know sandboxed solutions with c# are definitely deprecated, but the info around no code solutions is poor.
Apps I know apps can provision at both the app and host web level, but creating lists, libraries etc using the CSOM seems like a lot of effort and a step backwards.
PowerShell The SP Online PowerShell is nowhere near as powerful as on-prem SP. I can provision site collections through this, but not lists or libraries...
I'm keen to know how other developers are deploying to Office 365, specifically around provisioning sites with specific list definitions, libraries, content types and so on...
Thanks
