Emitter in SWC does not add expected space after '=>' in Arrow Functions

Hello friends, I am new to rust and SWC, I hope I am not wasting your time 🥹🙏🏻 I edited with extra space. 
// This is first test we need to have
console.log("We are here");
// This is another comment
const add = ()          => {
            // This is inner content
                return "Test" + "Test";
};


const min = ()          => {return "Test" + "Test"};
// This is first test we need to have
console.log("We are here");
// This is another comment
const add = ()          => {
            // This is inner content
                return "Test" + "Test";
};


const min = ()          => {return "Test" + "Test"};
Now I want to edit the add to adds, I is more than 2000 character and discord dose not let me send the code, so I put it in gist: https://gist.github.com/shahryarjb/6f314fa7fab85fb09751bb8146c919f3 My problem is it returns 
// This is first test we need to have
console.log("We are here");
// This is another comment
const adds = ()=>{
    // This is inner content
    return "Shahryar" + "Tavakkoli";
};
const min = ()=>{
    return "Shahryar" + "Tavakkoli";
};
// This is first test we need to have
console.log("We are here");
// This is another comment
const adds = ()=>{
    // This is inner content
    return "Shahryar" + "Tavakkoli";
};
const min = ()=>{
    return "Shahryar" + "Tavakkoli";
};
but I need to have an space after => and before{} like this 
const adds = () => {
    // This is inner content
    return "Test" + "Test";
};
const adds = () => {
    // This is inner content
    return "Test" + "Test";
};
how can do it? Thank you in advance

You should fork swc_ecma_codegen

Sorry as I understood there is no option and If i want to edit this I should change the lib source? Sorry I am not native english speaker

@kdy1 Sorry for interrupting, the space between lines like the top post needs to change source? I mean 
let code = r#"
            import "phoenix_html";
            import { Socket, SocketV1 } from "phoenix";
            import { TS } from "tsobject";

            // This is first test we need to have
            console.log("We are here");

            const min = () => {return "Shahryar" + "Tavakkoli"};
            "#;
let code = r#"
            import "phoenix_html";
            import { Socket, SocketV1 } from "phoenix";
            import { TS } from "tsobject";

            // This is first test we need to have
            console.log("We are here");

            const min = () => {return "Shahryar" + "Tavakkoli"};
            "#;
For now my code delete all the spaces 
import "phoenix_html";
import { Socket, SocketV1 } from "phoenix";
import { TS } from "tsobject";
// This is first test we need to have
console.log("We are here");
const min = ()=>{
    return "Shahryar" + "Tavakkoli";
};
import "phoenix_html";
import { Socket, SocketV1 } from "phoenix";
import { TS } from "tsobject";
// This is first test we need to have
console.log("We are here");
const min = ()=>{
    return "Shahryar" + "Tavakkoli";
};
Thank you in advance --- This is my emmiter 
    let mut emitter = Emitter {
        cfg: Config::default().with_minify(false),
        cm: cm.clone(),
        comments: Some(&comments),
        wr: JsWriter::new(cm.clone(), "\n", &mut buf, None),
    };
    let mut emitter = Emitter {
        cfg: Config::default().with_minify(false),
        cm: cm.clone(),
        comments: Some(&comments),
        wr: JsWriter::new(cm.clone(), "\n", &mut buf, None),
    };
