Finally after many times I decided to write a new article, in this particular case I'd like to talk of SharePoint Framework, probably a lot of you already know this new framework sponsored by Microsoft, where at the moment a rich community composed by MVP is contributing for this cause.
Only to spent few words about SharePoint Framework, allow to the developers to create a client web part for Office 365 and SharePoint 2016 On-Premise, currently with React, Angular and Knockout is also possible for the romantics of jQuery use the latter.
I warmly suggest to you, to start just in case It's a first approach with this new framework or also to remember all aspects, with the official guideline on the developer office website:
If you are a noob and you want to start your experience with SharePoint Framework, like requirements is required an Office 365 developer tenant please follow this guide Set up your Office 365 developer tenant
Just in case you have to install for the first time your development environment, please follow this link Set up your SharePoint client-side web part development environment
Target of this article is to show to you the ease of use of SharePoint Framework, at this purpose I created a client side web part to show the weather conditions, only for your info I used the React framework in my solution, but obviously you can use whatever you prefer (Angular, Knockout, jQuery or no framework).
Below a demo of my final result:
