Actually for now these libraries are identical and have feature parity. What is the purpose of having two identical libraries? Because PnPjs is an evolution of original PnP-JS-Core. Consider below points regarding new library:
- new organization name (github/pnp) corresponds to npm modules names (@pnp/)
- new library has better structure organization – there are multiple logically divided modules, thus making support and extensibility easier
- new library has exactly the same API and features as current PnP-JS-Core
- new library is a part of SharePoint Pattern & Practices (SharePoint PnP)
- the same people are behind it – Microsoft and awesome community
- development will be performed simultaneously in two libraries for about 5 months. If one feature is available in PnP-JS-Core, this feature also will be added to PnPjs (and vice versa)
- after 5 months (approximately summer 2018) PnP-JS-Core will be deprecated, it will be available in npm and cdn, however it will never receive new features, because main development will be transitioned to PnPjs (pnp/pnp)
What does it mean for you? If you are starting a new project, use new PnPjs library. If you have a chance to perform an upgrade for your current project, upgrade it to PnPjs. If you have a project with PnP-JS-Core – its fine, because the library will be in npm and on cdn, however new feature won’t be rolled out starting from summer 2018 for PnP-JS-Core specifically.
To listen about upcoming changes checkout PnPjs community call – starting from 19:00. If you want to listen to community calls live – use this calendar invite.
Hope this helps!
Do you know what is PnP-JS-Core? I hope so. If don’t know about PnP-JS-Core, here is a quick overview:
In other words that’s an wrapper over SharePoint REST API as well as other helper functions. PnP-JS-Core can speedup your development by providing a lot of useful functions, utilities, operators and objects to work with SharePoint. For example consider how it’s easy to do some routine operations:
I really recommend you to take a look at the official github repository here - https://github.com/SharePoint/PnP-JS-Core as well as wiki
The main purpose for PnP-JS-Core is using inside browser. You include sp-pnp-js into your html and you are ready to go. But the library is designed with extensibility and supportability in mind. That means you can run PnP-JS-Core not only in browser, but in Node.js environment too. Hmmm…. why do you need this, you might ask. Nowadays Node.js integrates in your development pipeline more and more. Do you know gulp, webpack, browserify, etc.? All this tools run on Node.js. With Node.js you can build any type of application – web applications, desktop (cross platform!) apps, micro services, Azure functions and many many other things. Sometimes you need to interact with SharePoint from you Node.js application. Ideally you would like to utilize PnP-JS-Core for that task as well. Meet node-pnp-js which will help you.
As you might guess the main issue when working with SharePoint from Node.js is authentication. When using inside browser, current user is already authenticated and you can use the library as is. For Node.js situation is different. There is no authenticated user and you have to implement authentication by your own. node-pnp-js uses my other library node-sp-auth as authentication provider. In the past I’ve created a sample of integration PnP-JS-Core and Node.js and node-pnp-js is just a logical continuation designed as a separate reusable package.
So let’s get started! More...
