@allex/rollup-plugin-node-globals

Some enhances base on rollup-plugin-node-globals

• Add extenssion defaults to ['.js', '.ts', '.mjs']
• Remove source files for npm dist.

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';
}

or

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.
