Composite business SharePoint Add-ins
Composite business add-ins are add-ins that are tightly integrated with your business processes and line-of-business (LOB) technologies (such as databases and web services). These add-ins typically include a number of complex interactions with users and with other technologies.
The sample composite business add-ins described in this section provide building blocks that you can use to integrate your technologies and processes with the SharePoint Add-in model.
SharePoint-hosted versus provider-hosted add-ins
Before you create composite business add-ins, you first need to decide where the add-ins will be hosted. SharePoint-hosted add-ins work best when you can scope your requirements to single-site implementations that you can handle with JavaScript. Provider-hosted add-ins are better for more complex business requirements.
The following table summarizes the factors to consider when you decide where to host your add-ins.
| SharePoint-hosted add-ins | Provider-hosted add-ins |
|---|---|
| You can do everything you need to do with JavaScript. | You need to use languages other than JavaScript. |
| The add-in does not need to do any work across more than one site; for example, team calendar add-ins and featured news rotators. | The add-in needs to access information and do work across more than a single site. For example, site collection provisioning add-ins. |
| Content is sensitive and needs to stay securely and entirely in SharePoint. | The add-in needs to integrate with other line-of-business technologies. |
| The add-in requires elevated permissions that are made possible by the add-in-only policy. | |
| The add-in requires a highly customized UI. |
