Summary
In this chapter, we learned what a Gatsby plugin is and what types exist. We learned about local plugin development and how to create source and theme plugins. We created both source and theme plugins and then tested them locally by including them on our site. We then learned about sharing plugins online. We discussed what you should consider before deploying a plugin and then learned how to share a plugin by publishing them online via npm. By completing this chapter, you should now feel confident that you can create and share source and theme plugins with ease. This has been a brief introduction to a massive topic, and I hope you can build on this knowledge to create plugins for any use case.
In the next chapter, we will look at another advanced concept – authentication. We will learn how to create login experiences on your website.
