Use this simple plugin to find complementary, split complementary, triad, tetrad, monochromatic, and analogous colors to a selected layer's fill.
Please see Figma's Making Plugins, their Plugin Documentation, and view their sample plugins to get started learning about plugins today.
The two main files are code.ts and ui.html. Figma strongly suggests that you use TypeScript when building plugins. Also, they recommend breaking up large plugins into multiple files and using Webpack in order to create your resulting file you'll submit for your plugin. For this plugin, I simply kept all of the code in one file. Lastly, I brought in jQuery rather than use vanilla js.
- Resources such as js / images / etc have to be remotely hosted if you do not use Webpack. (I hosted mine in an Azure blob storage). I will probably switch to Webpack in the next version so the plugin will be faster.
- The dimensions for the frame of your plugin are set as options in code.ts in the figma.showUI(...) line. When creating a new empty plugin, Figma leaves this out.
- If using jQuery (or similar) all document.ready / $(function(){... code runs correctly because your plugin is shown in an iFrame.
- This is stated all throughout Figma's docs but I will repeat it here. Your plugin code and html/iframe code are sandboxed but can message back and forth. Thus, your code.ts file can ONLY access the figma design document and your ui.html can ONLY access you plugin's UI.
- Lastly, the Figma team was VERY helpful when reviewing this plugin. The review only took 2 days (though they say it can take anywhere from 2-5 days). They not only accepted the plugin but gave me some feedback, constructive criticism, and encouragement.
