Example

var di = new require('sod-di')('MyDependencies');

di.register('pi').value(Math.PI);
di.register('logger').value(console);
di.register('area').factory(function(pi) {
    return function(radius) {
        return radius * radius * pi;
    };
});
di(function(logger, area) {
    logger.log(area(2)); // stdout: 12.566370614359172
});

Why

Using dependency injection instead of require() in your project hugely improves and simplifies the ability to write unit tests.

Features

• create multiple independent dependency injectors
• public / private dependencies
• import dependency injectors to access its public dependencies
• useful error handling
• 100% unit test coverage
