#tool building

Your first JavaScript tool might not be the next Babel or ESLint, but it can be built on them! Let's demystify the secret art of JavaScript tools, how they work, and how to build our own. We'll discover the opportunities in our everyday work to apply these techniques, writing our own ESLint rules to prevent mistakes and code transforms to make breaking changes easy to apply. We’ll walk through the fundamentals of working with an abstract syntax tree, and develop our understanding through a live-code. You will be amazed at what you can build, and together we’ll explore how to get started.

Widgets are custom, interactive objects you place in a Figma or Figjam file to extend functionality and make everything a bit more fun. They are written in a declarative style similar to React components, which gets translated to become a node on the canvas. So can you go the other way, from canvas to code? Yes! We’ll discuss how we used the public Figma plugin API to generate widget code from a design file, and make a working widget together using this.
