Because async functions are promises, you can create a static function on your class which executes an async function which returns the instance of the class:
class Yql {
constructor () {
// Set up your class
}
static init () {
return (async function () {
let yql = new Yql()
// Do async stuff
await yql.build()
// Return instance
return yql
}())
}
async build () {
// Do stuff with await if needed
}
}
async function yql () {
// Do this instead of "new Yql()"
let yql = await Yql.init()
// Do stuff with yql instance
}
yql()
Call with let yql = await Yql.init() from an async function.
