buncher v1.0.2

node.js module that collects remote data from different sources and can check it with JSON Schema

buncher

buncher collects data from different sources and accumulates it into one object. It will not return keys for incorrect items: incorrect URL, code is not 200, invalid data. These keys will be in err object.

Example:

get([
    { name: 'name1', url: "http://url-to.json", schema: 'tests/schema/name.json' },
    // type 'plain' means it will not be parsed as JSON
    { name: 'name2', url: "http://url-to.html/xml", type: 'plain' }
], function( err, results ) {
    console.log( results.name1 );   // parsed and checked JSON from name1
    console.log( results.name2 );   // plain HTML from name2
});
