The SharePoint Framework (SPFx) is a page and web part model that gives full help to customer side SharePoint advancement, simple mix with SharePoint information, and backing for open source tooling. With the SharePoint Framework, you can utilize present day web advancements and apparatuses in your favored improvement condition to assemble gainful encounters and applications that are responsive and versatile prepared from the very first moment. The SharePoint Framework works for SharePoint Online and furthermore for on-premises (SharePoint Development 2016 Feature Pack 2 and SharePoint 2019).

Key highlights of the SharePoint Framework incorporate the accompanying: 

It keeps running with regards to the present client and association in the program. There are no iFrames for the customization (JavaScript is inserted legitimately to the page).

• The controls are rendered in the ordinary page DOM. 
• The controls are responsive and available essentially. 

It empowers the engineer to get to the lifecycle notwithstanding render, load, serialize and deserialize, setup changes, and the sky is the limit from there.

It is framework-rationalist. You can utilize any JavaScript framework that you like: React, Handlebars, Knockout, Angular, and the sky is the limit from there.

The toolchain depends on regular open source customer advancement devices, for example, npm, TypeScript, Yeoman, webpack, and swallow.

Execution is dependable. 

End clients can utilize SPFx customer side arrangements that are endorsed by the inhabitant directors (or their agents) on all destinations, including self-administration group, gathering, or individual locales.

SPFx web parts can be added to both exemplary and current pages.

The runtime model enhances the Script Editor web part. It incorporates a hearty customer API, a HttpClient object that handles verification to SharePoint and Office 365, relevant data, simple property definition and arrangement, and that's only the tip of the iceberg.

On the off chance that you work fundamentally with C#, you need to get familiar with customer side JavaScript improvement. A large portion of your current JavaScript information identified with SharePoint solutions, be that as it may, is totally transferable, as the information models have not changed, and you'll utilize a similar REST administrations or JavaScript Object Model (JSOM), contingent upon your prerequisites. In the event that you are a C# engineer, TypeScript is a decent progress into the JavaScript world. The decision of IDE is up to you. Numerous engineers like to utilize the cross-stage IDE Visual Studio Code. Numerous designers likewise use items like Sublime and ATOM. Use what works best for you.

Why the SharePoint Framework? 

SharePoint was propelled as an on-premises item in 2001. After some time, a huge engineer network has broadened and formed it from various perspectives. Generally, the engineer network pursued similar examples and practices that the SharePoint item improvement group utilized, including web parts, SharePoint highlight XML, and that's only the tip of the iceberg. Numerous highlights were written in C#, gathered to DLLs, and sent to on-premises ranches.

That engineering functioned admirably in situations with just a single endeavor, yet it didn't scale to the cloud, where different inhabitants run next to each other. Subsequently, we presented two elective models: customer side JavaScript infusion, and SharePoint Add-ins. Both of these arrangements have advantages and disadvantages.

JavaScript infusion 

A standout amongst the most well known web parts in SharePoint Online is the Script Editor. You can glue JavaScript into the Script Editor web part and have that JavaScript execute when the page renders. It's basic and simple, yet powerful. It keeps running in a similar program setting as the page, and is in a similar DOM, so it can interface with different controls on the page. It is additionally generally performant, and easy to utilize.

There are a couple of drawbacks to this methodology, in any case. Initially, while you can bundle your answer with the goal that end clients can drop the control onto the page, you can only with significant effort give arrangement choices. Likewise, the end client can alter the page and adjust the content, which can break the web part. Another enormous issue is that the Script Editor web part isn't set apart as "Alright For Scripting". Most self-administration site accumulations (my-destinations, group locales, bunch destinations) have a component known as "NoScript" empowered. In fact, it is the expulsion of the Add/Customize Pages (ACP) authorization in SharePoint. This implies the Script Editor web part will be hindered from executing on these destinations.

SharePoint Add-in model 

The present choice for arrangements that keep running in NoScript locales is the include/application part model. This usage makes an iFrame where the genuine encounter lives and executes. The bit of leeway is that since it's outside to the framework and has no entrance to the present DOM/association, it's simpler for data laborers to trust and send. End clients can introduce include ins NoScript locales.

There are a few drawbacks to this methodology also. Initially, they keep running in an iFrame. iFrames are slower than the Script Editor web part, since it requires another solicitation to another page. The page needs to experience confirmation and approval, make its own calls to get SharePoint information, load different JavaScript libraries, and the sky is the limit from there. A Script Editor web part may ordinarily take, for instance, 100 milliseconds to load and render, while an application part may take 2 seconds or more. Furthermore, the iFrame limit makes it progressively hard to make responsive structures and acquire CSS and theming data. iFrames do have more grounded security, which can be helpful for you (your page is difficult to reach by different controls on the page) and for the end client (the control has no entrance to their association with Office 365).

SharePoint Framework 

Verifiably, we made web parts as full trust C# gatherings that were introduced on the cloud servers. In any case, current improvement models generally include JavaScript running in a program making REST API calls to the SharePoint and Office 365 back-end outstanding burdens. C# gatherings don't work in this world. We required another improvement model. The SharePoint Framework is the following advancement in SharePoint improvement.

A SharePoint Add-in is an independent bit of usefulness that broadens the capacities of SharePoint sites to take care of a well-characterized business issue.

Include ins don't have custom code that keeps running on SharePoint servers. Rather, all custom rationale moves "up" to the cloud, or "down" to customer PCs, or "over" to an on-premises server that is outside the SharePoint ranch or SharePoint Online membership. Keeping custom code off SharePoint servers gives consolation to SharePoint heads that the include can't hurt their servers or decrease the presentation of their SharePoint Online sites.

Business rationale in a SharePoint Add-in can get to SharePoint information through one of the few customer APIs incorporated into SharePoint. Which API you use for your include in depends certain other plan choices you make.

Practically all real kinds of SharePoint content management segments can be a piece of a SharePoint Add-in, including pages, records, work processes, custom substance types, list formats, web parts, and then some.

The SharePoint sites where SharePoint Add-ins are introduced, and from which clients dispatch them, are called host networks. The SharePoint parts, notwithstanding, are for the most part in a unique kid web of the host web called the include web.
