Comparison of tsc and swc compilation results, why ?

[schacker]

input, two files

index.ts

import { one } from "./one/index"

console.log(one, one.one1(1))

one.ts

const one1 = (params) => {
  console.log("one1", params)
}
const one2 = (params) => {
  console.log("one2", params)
}
const one3 = (params) => {
  console.log("one3", params)
}

export const one = {
  one1,
  one2,
  one3
}

results

tsc's result

one.js

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
exports.one = void 0;
const one1 = (params) => {
    console.log("one1", params);
};
const one2 = (params) => {
    console.log("one2", params);
};
const one3 = (params) => {
    console.log("one3", params);
};
exports.one = {
    one1,
    one2,
    one3
};

index.js

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
const index_1 = require("./one/index");
console.log(index_1.one, index_1.one.one1(1));

now, working well !

swc's result

one.js

"use strict";
Object.defineProperty(exports, "a", {
    value: !0
}), exports.one = void 0, exports.one = {
    b: function(a) {
        console.log("one1", a);
    },
    c: function(a) {
        console.log("one2", a);
    },
    d: function(a) {
        console.log("one3", a);
    }
};

index.js

"use strict";
var _index = require("./one/index");
console.log(_index.a, _index.a.b(1));

swc's key config

{
    "module": {
        "type": "commonjs",
        "strict": false,
        "strictMode": true,
        "lazy": false,
        "noInterop": false,
        "ignoreDynamic": false
    }
}

"@swc/cli": "^0.1.51"
"@swc/core": "^1.2.105"
build script: npx swc src -d ./dist --only **/*.ts --config-file .swcrc --env-name='test' --copy-files

now, can't run !

why ???

You should post your tsconfig.json, too.

[schacker]

what's your swc config ?

[kdy1]

What you posted.

{
    "module": {
        "type": "commonjs",
        "strict": false,
        "strictMode": true,
        "lazy": false,
        "noInterop": false,
        "ignoreDynamic": false
    }
}

{
    "module": {
        "type": "commonjs",
        "strict": false,
        "strictMode": true,
        "lazy": false,
        "noInterop": false,
        "ignoreDynamic": false
    }
}

key config: jsc.minify.mangle.property

I checked my other configuration items and found that the property attribute is set to {}, but I checked the documentation and the default is {}. But after manual setting, the two results are different?

Is the document wrong?

[schacker]

When I delete the property, the result is correct!

[kdy1]

Your description seems like a description about a bug of the property mangler.
But property mangler is not a something easy to use. You cannot simply enable it just like you did.

The document is wrong if it says it's {} by default. (I can't see swc.rs now).
