How to get string value from Promise value ?

[magic-thomas]

I want to return string variable from set_file function, but it return 'Promise' type.

how can I get string from return value ?

// +server.js
export async function POST({ request }) {
    let file_name = set_file();
    console.log(file_name)
}

async function set_file() {
    const date = new Date();
    var ms = date.getTime();
    return 'static/' + ms + '.png'
}

Promise { 'static/1663245525814.png' }

Promises are a basic JavaScript thing, that needs to be awaited:

// +server.js
export async function POST({ request }) {
    let file_name = await set_file();
    console.log(file_name)
}

async function set_file() {
    const date = new Date();
    var ms = date.getTime();
    return 'static/' + ms + '.png'
}

But since you do not do any async stuff in the set_file function, you can just omit the async from the function declaration.
