Put a line of code in your extension block, push to your development store. Now enable previews in your App by clicking the link the CLI gives you, and then visit the store, theme, customizer. Now you can test if your extension loaded by enabling it in the customizer and seeing the code from your block, in the theme, where you put it.

这很容易做到。Shopify已经解决了大部分问题，所以我发现从在代码编辑器中键入，使用CLI并在主题中看到结果只需要很少的按键。
我建议你玩并遵循Shopify食谱来达到这一点。
