Office Dev PnP Web Cast – JavaScript performance considerations with SharePoint

In this PnP Web Cast we concentrated on the JavaScript development performance considerations with SharePoint sites. There are many scenarios in the typical deployments with SharePoint add-in model where you’d take advantage of JavaScript development patterns and it’s important that you ensure that your code is performing properly also from performance perspective. This is follow up on the JavaScript development patterns with SharePoint web cast few weeks back.

As part of the app / add-in model development practices you will be moving your customization logic from the server side to client side technologies. In similar ways as with the server side implementations, you will need to consider performance of your implementations in client side technologies.

Patrick is Senior Consultant from Microsoft Services and Office 365 Dev PnP Core team member. During the video Patrick is demonstrating how to write JavaScript based customization efficiently and what to consider from performance perspective. You can find used code sample from the PnP library named as Core.JavaScript. This solution is consolidated set of JavaScript examples for use in your SharePoint projects targeted for Office 365 or on-premises. Target is to continue extending this as the “PnP Core library” for JavaScript based implementations and you can take advantage of the provided JavaScript libraries in your customizations.

What is Office 365 Developer Patterns and Practices (PnP) web cast series? Office 365 Developer Patterns and Practices

We have started this weekly Office 365 Developer Patterns and Practices (PnP) web cast series to cover different patterns, practices and topics around development with Office 365 and SharePoint. Majority of the topics are valid for the Office 365 and SharePoint on-premises. Our objective is to release new around 30-45 minute long web cast each Monday with few slides and live demo on the covered topic. All web casts are published at the PnP Channel 9 video blog with additional references on the existing materials.

PnP is community driven open source project where Microsoft and external community members are sharing their learning’s around implementation practices for Office 365 and SharePoint on-premises (add-in model). Active development and contributions happen our GitHub project under Dev branch and each month there will be a master merge (monthly release) with more comprehensive testing and communications. Latest activities and future plans are covered in our monthly community calls which are open for anyone from the community. Download invite from

This is work done by the community for the community without any actual full time people. It’s been great to find both internal and external people who are willing to assist and share their learning’s for the benefit of others. This way we can build on the common knowledge of us all. Currently program is facilitated by Microsoft, but already at this point we have multiple community members as part of the Core team and we are looking to extend the Core team with more community members.
