npm install xmlhttp> A tiny (309B) library to detect when window globals are defined and ready to use~!
This module exposes three module definitions:
* ES Module: dist/is-ready.es.js
* CommonJS: dist/is-ready.js
* UMD: dist/is-ready.min.js
If using the UMD bundle, the library is exposed as is-ready globally.
``
$ npm install --save is-ready
`js
const isReady = require('is-ready');
// Check if "window.firebase" is loaded
isReady('firebase').then(_ => {
firebase.initializeApp(...);
});
// Check if "window.firebase" & "window.firebase.auth" are loaded
isReady(['firebase', 'firebase.auth']).then(_ => {
firebase.auth().onAuthStateChanged(...);
});
// This is equivalent (but requires dependency/hierarchy knowledge)
isReady('firebase').then(_ => {
//=> ready: window.firebase
isReady('firebase.auth').then(_ => {
//=> ready: window.firebase.auth
});
});
`
Returns: Promise
#### name
Type: String or Array
The global variable name(s) to check. These are the would-be variable(s) mounted to window once loaded. For example, if you know a library will be accesible as window.foobar, then you would use isReady('foobar').
Any nested or sub-module names should be delimited with a .; eg firebase.auth. See dlv` for more info on dot-notation access.
