The Geekle React Global Online Summit took place in April 2022, AG Grid helped sponsor the conference.
And the free streamed events for all their conferences can be viewed on their YouTube channel, with conferences for Angular, Game Development, Flutter, Data Science, Vue, Java and more.
I've listed a few of the talks that were most relevant to me.
A Deep Dive into React Keys - by Joon Park explains how keys are used in conjunction with the React rendering process, and describing the Eager Update pattern where a GUI renders, and updates the server side state in the background. Based on this I was able to update some Storybook code to reflect new grid states when user properties were changed.
Josh Goldberg covered various approaches for stubbing and mocking when testing components with external dependencies. Covering
jest.mock at a global and module level. Also dependency injection by passing APIs as props and via React context. This is in the Props, Mocks, and Context: Unit Testing Heavy Components talk. The Q&A session provided a good answer covering when to use Context and when to use Redux.
Nick Nisi provided a clear example of using XState state machines in a React application in the talk Componentizing Application State. Also interesting to see the state machine updating in the dev tools view.
It's worth looking through the list of talks and see which stand out for you (there is a handy table of contents in the description of the live stream).
