A tool for developing software in a GOP(granule oriented programming) way
Install it via npm (or yarn)
npm install
const Granule = require('granulejs')
const env = new Granule(testFunc, dataProvider)Here testFunc is a function to test the context vars (optional, provided by dataProvider which is another function or an Object) fit environment currently which this binds on the injected class.
// ...
class ClassName {
methodName () {
// do sth...
}
}
// ...
env.inject(ClassName, 'methodName', function (...params) {
console.log('inject success')
// do other things...
})We inject this granule into a class called ClassName, change the behavior of method methodName under the situation testFunc defined.
Notice testFunc, dataProvider, new behaviors defined in injections could be async function. So we must call this method with await, even all these functions above are sync.
Use extend method to make a granule "extends" from parent granule. The child granule will not be active unless all its parents(a parent chain of granules) are active(pass their tests) and its own testFunc returns true.
const childEnv = env.extend(newTest, newDataProvider)
childEnv.inject(NewClass, 'newMethodName', function () {
// do sth...
})Child granule can inject the same class, the same method its parent does. Generally, each grandule can inject any class, but the last injected one (also it is active) can be executed.
