@overlook/util-memoize v0.1.1

Overlook framework memoize utility function

Usage

Memoize a class extension function.

This prevents multiple subclasses being created, where extend() is called multiple times to extend the same class.

// Define Route class extension
const memoize = require('@overlook/util-memoize');

const extend = memoize(function(Route) {
  return class MyExtendedRouteClass extends Route {
    /* ... */
  };
});

// Use it
const {Route} = require('@overlook/framework');
const RouteSubclass = extend(Route);
const RouteSubclass2 = extend(Route);
// RouteSubclass2 === RouteSubclass

Tests

Use npm test to run the tests. Use npm run cover to check coverage.
