Promises, ES6, Examples and more

• You can return Promises (aka Thenables) from the init() functions. If any of the composed init() functions returns a promise then the stamp (and everything it is composed with) will always return a promise. Example:

const promisedStamp = stampit.init(() => { return Promise.resolve(); });
const regularStamp = stampit.refs({ data: 1 });
const regularStamp2 = stampit.methods({ foo() { console.log('foo'); } });

var promisedStamp2 = regularStamp.compose(promisedStamp).compose(regularStamp2);
promisedStamp2.create(); // returns a Promise!

More examples are in the tests.

• When converting a constructor it's "static" properties are now converted to stampit statics.

function OldFashionedConstructor() {}
OldFashionedConstructor.prototype.regularMethod = function() {};
OldFashionedConstructor.staticMethod = function() {};

const stamp = stampit.converConstructor(OldFashionedConstructor);
stamp.staticMethod(); // It exist!

• Stampit was converted to ES6. But, it trasplies to ES5 for obvious reasons. All tests are ES6 too. ESLint is used now instead of JSHint.
• An internal mixer.js module was split out to a separate npm module supermixer.
• Many useful examples were added. See ADVANCED_EXAMPLES.md.
• Stampit tests coverage can be checked with npm run cov. It's 100% now.
• Node Security Project and dependency checks are applied to each build now.
• Few corner cases were improved for better stability.
