Node.js

npm install bluebird

Then:

var
 Promise
 =
 require
(
"bluebird"
);

Alternatively in ES6

import
 *
 as
 Promise
 from
 "bluebird"
;

If that ES6 import doesn't work

import
 {
Promise
}
 from
 "bluebird"
;

Browsers

(See also Installation .)

There are many ways to use bluebird in browsers:

• Direct downloads
  • Full build bluebird.js
  • Full build minified bluebird.min.js
  • Core build bluebird.core.js
  • Core build minified bluebird.core.min.js
• You may use browserify on the main export
• You may use the bower package.

When using script tags the global variables Promise and P (alias for Promise ) become available. Bluebird runs on a wide variety of browsers including older versions. We'd like to thank BrowserStack for giving us a free account which helps us test that.
