Package Exports

rollup-plugin-node-globals

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 (rollup-plugin-node-globals) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

rollup-plugin-node-globals

Plugin to insert node globals including so code that works with browserify should work even if it uses process or buffers. This is based on rollup-plugin-inject .

process
global
Buffer
__dirname
__filename

Plus process.nextTick and process.browser are optimized to only pull in themselves and __dirname and __filename point to the file on disk

There are a few options to control output

process - pass false to disable process polyfilling
global - pass false to disable global polyfilling
buffer - pass false to disable Buffer polyfilling
dirname - pass false to disable __dirname polyfilling
filename - pass false to disable __filename polyfilling
baseDir which is used for resolving __dirname and __filename.

examples

var foo;
if (process.browser) {
  foo = 'bar';
} else {
  foo = 'baz';
}

turns into

import {browser} from 'path/to/process';
var foo;
if (browser) {
  foo = 'bar';
} else {
  foo = 'baz';
}

but with rollup that ends up being

var browser = true;
var foo;
if (browser) {
  foo = 'bar';
} else {
  foo = 'baz';
}

var timeout;
if (global.setImmediate) {
  timeout = global.setImmediate;
} else {
  timeout = global.setTimeout;
}
export default timeout;

turns into

import {_global} from 'path/to/global.js';
var timeout;
if (_global.setImmediate) {
  timeout = _global.setImmediate;
} else {
  timeout = _global.setTimeout;
}
export default timeout;

which rollup turns into

var _global = typeof global !== "undefined" ? global :
            typeof self !== "undefined" ? self :
            typeof window !== "undefined" ? window : {}

var timeout;
if (_global.setImmediate) {
  timeout = _global.setImmediate;
} else {
  timeout = _global.setTimeout;
}
var timeout$1 = timeout;

export default timeout$1;

With that top piece only showing up once no matter how many times global was used.
