Enabling The Developer Site Collection Feature SharePoint Online Office 365 -CSOM

This blog will help you to enable the development feature in SharePoint 2013, using JSOM.

In SharePoint 2013, we have a new site template called Developer Site Template. It is a site template, which is used extensively for app development and you can only deploy apps for SharePoint to a Developer Site.

I have a scenario, where I need to enable the Developer Site Collection feature for an existing Site Collection, which may be a team site or publishing site. There isn't a button in Site Collection features which allows you to enable this.

If you were on SharePoint 2013 On-Premises, you’d just run Enable-SPFeature, which is shown below.

Enable-SPFeature e374875e-06b6-11e0-b0fa-57f5dfd72085 –url http://gowthamr.sharepoint.com

With SharePoint Online, we can't do this directly, so I have created a simple method to solve this. We can run this script in our Internet Browser console.

<script>
$(document).ready(function () {

var featureID="e374875e-06b6-11e0-b0fa-57f5dfd72085";
ActivateFeature(featureID);

});

function ActivateFeature(featureGuid)
{
var clientContext = new SP.ClientContext.get_current();
var site = clientContext.get_site();
var guid = new SP.Guid('{'+featureGuid+'}');

var featDef = site.get_features().add(guid, false, SP.FeatureDefinitionScope.site);

clientContext.executeQueryAsync(Function.createDelegate(this, this.OnSuccess), Function.createDelegate(this, this.OnFail));
}

function OnSuccess(sender, args) {
    alert('Successfully enabled Developement feature!');
}

function OnFail(sender, args) {
    alert('Fail: ' + args.get_message() + '\n' + args.get_stackTrace());
}

</script>
