Source code: polyfill.js → external → main.js
js
// main.js
import "./polyfill.js";
import "external";
console.log("main");
// polyfill.js
console.log("polyfill");
Bundle code: external → polyfill.js → main.js
js
import "external";
console.log("polyfill");
console.log("main");
Solution:
If polyfill.js ends up in a different chunk than main.js, correct execution order will be preserved. Example: not chunk -> chunk
