Polyfills

GJS does not implement some common APIs that you would expect from a JavaScript runtime. See this gjs issue for context.

fetch

Gjsx provides a basic implementation for the fetch API.

import { fetch, URL } from "gjsx/fetch"

const url = new URL("https://some-site.com/api")
url.searchParams.set("hello", "world")

const res = await fetch(url, {
    method: "POST",
    body: JSON.stringify({ hello: "world" }),
    headers: {
        "Content-Type": "application/json",
    }
})

const json = await res.json()
