Note: this is a fork of the original closure-library, it is not intended to be installed using npm, instead, it is intended to be pulled as a git submodule for @dnory0/node-blockly project to include the version that is compatible with the blockly project (which is itself a submodule too), consider developing on @dnory0/node-blockly project.

Install the official package from npm.

npm install google-closure-library

Require the package and use goog.require normally.

require("google-closure-library");

goog.require("goog.crypt.Sha1");

var sha1 = new goog.crypt.Sha1();
sha1.update("foobar");
var hash = sha1.digest();
