I bet you know fairly popular PnP-JS-Core library. It also known as sp-pnp-js, because the original file and corresponding module in npm called sp-pnp-js. Home page on github advertise it as “JavaScript Core Library” (using analogy to PnP-Sites-Core). However today there is another (very similar) library at pnp/pnp (or PnPjs) which looks very similar. What is the purpose of this new library? Should I use it or continue using old PnP-JS-Core?

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!
