How to convert javascript obj into URL parameters with nested object in it?

Question

I have a react app that handles routing in the application. I am getting json object from db with parameters that will look like this:

    let paramsObj = {
        state: {
            Corp: "CorpCode",
            Location: "LocationCode",
            IsCorp: false
        }
    };

How to convert paramsObj and encode it to URL parameters so the final string would look like this?state=%7B%20Corp%3A%20%22CorpCode%22%2C%20Location%3A%20%22LocationCode%22%2C%20IsCorp%3A%20false%20%7D

let paramsObj = {
    state: {
        Corp: 'CorpCode',
        Location: 'LocationCode',
        IsCorp: false,
    },
};

const urlSearchParams = Object.keys(paramsObj).reduce((output, key) => {
    const value = paramsObj[key];
    const valueString = JSON.stringify(value);
    output.append(key, valueString);
    return output;
}, new URLSearchParams());

console.log(urlSearchParams.toString());

It should work somehow in combination new URLSearchParams().toString(). your solution gives me link without "state=" part which should be taken from json object

You can do it with reduce as seen now

Is it ok that in this solution string is URI encoded two times? Like: 1.%7B%20Corp%3A%20%22CorpCode%22%2C%20Location%3A%20%22LocationCode%22%2C%20IsCorp%3A%20false%20%7D 2.%257B%2520Corp%253A%2520%2522CorpCode%2522%252C%2520Location%253A%2520%2522LocationCode%2522%252C%2520IsCorp%253A%2520false%2520%257D

You are right, it was a mistake, the encodeURIComponent encoding I added was redundant and is handled by URLSearchParams. I fixed the code block in the answer.
