webmiddle-service-arraymap v0.3.0

webmiddle-service-arraymap

Maps an array into an array of resources by executing a callback on each item.

Install

npm install --save webmiddle-service-arraymap

Usage

import { PropTypes, rootContext } from 'webmiddle';
import ArrayMap from 'webmiddle-service-arraymap';

const MyService = () => (
  <ArrayMap
    name="myResources"
    array={[1, 2, 3]}
    callback={num =>
      <SubService
        name={"resource" + num}
        {/*...*/}
      />
    }
  />
);

rootContext.evaluate(<MyService />)
.then(resource => {
  console.log(resource.name); // "myResources" 
  console.log(resource.contentType); // "application/json"
  console.log(resource.content); // [resource1, resource2, resource3]
});

How it works

In terms of implementation it is similar to the Parallel service, meaning that the items are mapped concurrently.

The service resolves with a JSON resource whose content is the obtained array.
