diddly

Pure functional dependency injection for TypeScript

NOTE: This library is very experimental.

Benefits

• 100% type safe
• Purely functional
• Immutable
• Circular dependencies are impossible

Example

import { createContainer } from 'diddly';

function printNameAndAge(name: string, age: number) {
  console.log(`${name} is aged ${age}`);
}
​
const container = createContainer()
  .register('someAge', value(5))
  .register('someName', value('Timmy'))
  .register('fn', func(printNameAndAge, 'someName', 'someAge'));
​
const print = container.resolve('fn');
print(); // Prints "Timmy is aged 5"
