This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (globalthis) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

globalThis

An ECMAScript spec-compliant polyfill/shim for globalThis. Invoke its "shim" method to shim globalThis if it is unavailable.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec proposal.

Most common usage:

var globalThis = require('globalthis')(); // returns native globalThis if compliant
    /* or */
var globalThis = require('globalthis/polyfill')(); // returns native globalThis if compliant

Example

var assert = require('assert');

// the below function is not CSP-compliant, but reliably gets the
// global object in sloppy mode in every engine.
var getGlobal = Function('return this');

assert.equal(globalThis, getGlobal());

/* when `globalThis` is not present */
var shimmedGlobal = require('globalthis').shim();
    /* or */
var shimmedGlobal = require('globalthis/shim')();

assert.equal(shimmedGlobal, globalThis);
assert.equal(shimmedGlobal, getGlobal());

/* when `globalThis` is present */
var shimmedGlobal = require('globalthis').shim();

assert.equal(shimmedGlobal, globalThis);
assert.equal(shimmedGlobal, getGlobal());
