In this chapter, we took a look at troubleshooting common toolchain issues with the SharePoint Framework. As the framework, along with its hooks into open source tools and platforms continues to evolve rapidly, it is not too uncommon to run into new issues and errors in your projects. The approaches we showed aim to quickly help you isolate the issues and better help you understand why your code does not deploy or compile as expected.

Then, we covered analyzing and optimizing your code primarily through the use of not bundling larger libraries in your deployable package. You can reference these common libraries as external libraries with the use of CDNs.

In addition, we also configured Visual Studio Code to support debugging through Google Chrome with the use of Chrome's remote debugging capabilities. This approach also works for the hosted version of SharePoint Workbench in SharePoint Online.

In the next chapter, we will take a look at security and APIs in SharePoint.
