In previous post ‘SharePoint hosted Add-In : Read list data
: JSOM’, we saw how to create SharePoint hosted Add-In to read data from
SharePoint. In this post, we will see how to deploy SharePoint Add-In as App
Part. So that, this Add-In can be added to any page in SharePoint.
Step 1- Add new Client Web Part to your Add -In project.
Step 2- Create a new page or you can also use existing
Default.aspx page of Add-In for client web part content.
Step 3- Create a blog subsite ‘Vendor’. In App part, we will
read data from this blog posts.
Step 4- Open Client web part Element.xml file and update
Title and Description.
Step 5- Deploy your Add-In
Step 6- Add your App Part from Apps category as shown below.
Step 7- Now you can see your Add-In as App part in your
SharePoint sites page.
