Add params to path rest.js

Question

I'm using rest.js from npm install rest and cannot get my params to append to the path in the request. Here is my client.js

'use strict';

var rest = require('rest');
var defaultRequest = require('rest/interceptor/defaultRequest');
var mime = require('rest/interceptor/mime');
var uriTemplateInterceptor = require('rest/interceptor/template');
var errorCode = require('rest/interceptor/errorCode');
var baseRegistry = require('rest/mime/registry');

var registry = baseRegistry.child();

registry.register('text/uri-list', require('./api/uriListConverter'));
registry.register('application/hal+json', require('rest/mime/type/application/hal'));

module.exports = rest
        .wrap(mime, { registry: registry })
        .wrap(uriTemplateInterceptor)
        .wrap(errorCode)
        .wrap(defaultRequest, { headers: { 'Accept': 'application/hal+json' }});

I used the template interceptor suggested here https://github.com/cujojs/rest/blob/master/docs/interceptors.md#module-rest/interceptor/template. Here is my code making the request:

client({method: 'GET', path: 'api/questions/page', params: {offset: 0, limit:10}})
        .then(response => console.log(response.request.path));

The output of the console.log(response.request.path) is api/questions/page and it also doesn't show the request params in the network log. How do I get the params to append to the path?

I think that is using a different library, the link I posted above says the template interceptor should automatically append the params to the path but it isn't working — gary69, Dec 01 '17 at 23:28

I just created my own interceptor

define(function(require) {
    'use strict';

    var interceptor = require('rest/interceptor');

    return interceptor({
        request: function (request /*, config, meta */) {
            /* If the URI is a URI Template per RFC 6570 (http://tools.ietf.org/html/rfc6570), trim out the template part */
            if (request.path.indexOf('{') === -1) {
                if(request.params != null){
                    request.path = request.path + '?'
                    Object.keys(request.params).forEach(function eachKey(key){
                        request.path = request.path + key + '=' + request.params[key] + '&'; 
                    });
                    request.path = request.path.slice(0, -1);
                }
                return request;
            } else {
                request.path = request.path.split('{')[0];
                return request;
            }
        }
    });

});
