rollup-plugin-node-globals2
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
- passfalse
to disable process polyfillingglobal
- passfalse
to disable global polyfillingbuffer
- passfalse
to disable Buffer polyfillingdirname
- passfalse
to disable__dirname
polyfillingfilename
- passfalse
to disable__filename
polyfillingbaseDir
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.
