Align module order with esbuild when mixed load esm and cjs modules.

[7086cmd]

Not hurry to solve it, but this open for tracking it.

In Rolldown, the generated code order is firstly y that x.

Actually this is not same with esbuild:

TestLoaderDataURLCommonJSAndES6
---------- /out.js ----------
// x.txt
var require_x = __commonJS({
  "x.txt"(exports, module) {
    module.exports = "data:text/plain;charset=utf-8,x";
  }
});

// y.txt
var y_default = "data:text/plain;charset=utf-8,y";

// entry.js
var x_url = require_x();
console.log(x_url, y_default);

you could open an issue to track, it is not related to dataurl encoding.

more generate case:

// index.js
import {a} from './a.js'
import {b} from './b.js'
console.log(a, b, c);
// a.js
export const a = 1000;
// b.js
export const b = 10000;

rolldown

//#region a.js
const a = 1000;

//#endregion
//#region b.js
const b = 10000;

//#endregion
//#region index.js
console.log(a, b, c);

//#endregion

esbuild

// a.js
var a = 1e3;

// b.js
var b = 1e4;

// entry.js
console.log(a, b, c);

Mixed cjs and esm

// index.js
const a = require('./a.js')
import {b} from './b.js'
console.log(b, a);
// a.js
export const a = 1000;
// b.js
export const b = 10000;

rolldown

// ...snip runtime
//#endregion
//#region b.js
const b = 10000;

//#endregion
//#region a.js
var a_ns, a$1;
var init_a = __esmMin(() => {
	a_ns = {};
	__export(a_ns, {a: () => a$1});
	a$1 = 1000;
});

//#endregion
//#region index.js
const a = (init_a(), __toCommonJS(a_ns));
console.log(b, a);

//#endregion

esbuild

// a.js
var a_exports = {};
__export(a_exports, {
  a: () => a
});
var a;
var init_a = __esm({
  "a.js"() {
    a = 1e3;
  }
});

// b.js
var b = 1e4;

// entry.js
var a2 = (init_a(), __toCommonJS(a_exports));
console.log(a2, b, c);
