Syringe is a small utility you can use to inject dependencies into functions.
Syringe works by parsing the function signature to look for variable names.
The module then takes one or more parameters, a function to inject and any number of objects where the keys may match the named parameters required by the injected function.
In this example myFunc expects two parameters, arg1 and arg2. The Syringe function receives other parameters, but myFunc will only have access to the ones it asked for.
var inject = require('syringe-js');
var myFunc = function(arg1, arg2) {
//...
}
var injected = inject(myFunc, {
arg1: 'Foo',
arg2: 'Bar',
arg3: 'Ponies',
arg4: {
pie: 'apple'
}
});Bug fixes and new features are of course very welcome!
To get started developing:
- Install Grunt
- Install dependencies with
npm install - Run the test suite with
npm test
Please accompany any Pull Requests with the relevant test cases and make sure everything else still passes :).
