hapi plugin to handle custom string array query param format

server-ext.js

var Url = require('url');
// This ext add support of string-array value in query param
// syntax is `?param=[value1, value2]` which return `{ param: ['value1', 'value2'] }`

// It turns out that we don't need this at all. Because even hapi.js 8.x support `param=value1&param=value2` which is more standard!

// hapi.js supports param=value1&param=value2
server.ext({
  type: 'onRequest',
  method: function(request, reply) {
    var url = Url.parse(request.url, true);
    var ArrayLikeValue = /^\[[^\]]+\]$/;
    var hasCutomArrayLikeValue = false;
    if(url.query) {
      for(paramName in url.query) {
        if (url.query.hasOwnProperty(paramName) && ArrayLikeValue.test(url.query[paramName])) {
          var values = url.query[paramName].slice(1, -1).split(',');
          url.query[paramName] = values;
          hasCutomArrayLikeValue = true;
        }
      }
      if(hasCustomeArrayLikeValue) {
        request.setUrl(Url.format(url));
      }
    }
    return reply.continue();
  }
