-==================
+# node-url-assembler
 
-> Assemble urls from route-like templates (/path/:param) 
+> Assemble urls from route-like templates (/path/:param)
 
 Chainable utility to assemble URLs from templates
 
-Installation
-------------
+## Installation
 
     npm install --save url-assembler
 
-Usage
------
+## Usage
 
 #### Basic
 
 ```javascript
 UrlAssembler()
-  .template('/users/:user')
-  .param('user', 8)
-  .param('include', 'address')
+  .template("/users/:user")
+  .param("user", 8)
+  .param("include", "address")
   .query({
-    some: 'thing',
+    some: "thing",
     other: 1234
   })
-  .toString() // => "/users/8?include=address&some=thing&other=1234
+  .toString(); // => "/users/8?include=address&some=thing&other=1234
 ```
 
 #### With base URL
 
 Since you more often than not need a hostname and a protocol to go with this
 
 ```javascript
-UrlAssembler('http://my.domain.com:9000')
-  .template('/groups/:group/users/:user')
+UrlAssembler("http://my.domain.com:9000")
+  .template("/groups/:group/users/:user")
   .param({
-    group: 'admin',
-    user: 'floby'
+    group: "admin",
+    user: "floby"
   })
-  .toString() // => "http://my.domain.9000/groups/admin/users/floby"
+  .toString(); // => "http://my.domain.9000/groups/admin/users/floby"
 ```
 
 #### Incremental assembling
 
 You can also incrementally build your URL.
 
 ```javascript
-UrlAssembler('https://api.site.com/')
-  .prefix('/v2')
-  .segment('/users/:user')
-  .segment('/projects/:project')
-  .segment('/summary')
+UrlAssembler("https://api.site.com/")
+  .prefix("/v2")
+  .segment("/users/:user")
+  .segment("/projects/:project")
+  .segment("/summary")
   .param({
-    user: 'floby',
-    project: 'node-url-assembler'
+    user: "floby",
+    project: "node-url-assembler"
   })
-  .toString() // => 'https://api.site.com/v2/users/floby/projects/node-url-assembler/summary'
+  .toString(); // => 'https://api.site.com/v2/users/floby/projects/node-url-assembler/summary'
 ```
 
 #### making requests
@@ -66,105 +63,112 @@ If `url-assembler` finds the [`request`](npmjs.com/package/request) module. Then
 is available on every instance which can be used to make requests.
 
 ```javascript
-var google = UrlAssembler('https://google.com').query('q', 'url assembler');
+var google = UrlAssembler("https://google.com").query("q", "url assembler");
 
-google.request.get() // => makes a GET request to google
+google.request.get(); // => makes a GET request to google
 
 // you can still pass any other option to request
-google.request.get({json: true})
+google.request.get({ json: true });
 ```
 
-Design
-------
+## Design
 
 Every method (except `toString()`) returns a new instance of `UrlAssembler`. You can
 consider that `UrlAssembler` instances are immutable.
 
 Because of this, you can use a single instance as a preconfigured url to reuse throughout your codebase.
 
 ```javascript
-var api = UrlAssembler('http://api.site.com');
+var api = UrlAssembler("http://api.site.com");
 
-var userResource = api.segment('/users/:user');
+var userResource = api.segment("/users/:user");
 
-var userV1 = userResource.prefix('/v1');
-var userV2 = userResource.prefix('/v2');
+var userV1 = userResource.prefix("/v1");
+var userV2 = userResource.prefix("/v2");
 
-var userFeedResource = userV2.segment('/feed');
+var userFeedResource = userV2.segment("/feed");
 
-var authenticated = api.query('auth_token', '123457890');
+var authenticated = api.query("auth_token", "123457890");
 
-var adminResource = authenticated.segment('/admin');
+var adminResource = authenticated.segment("/admin");
 ```
 
 In addition, an instance of `UrlAssembler` is a valid object to pass
 to `url.format()` or any function accepting this kind of object as
 parameter.

-API Reference
--------------
+## API Reference
 
 ###### `new UrlAssembler([baseUrl])`
+
 - `baseUrl`: will be used for protocol, hostname, port and other base url kind of stuff.
 - **returns** an instance of a URL assembler.
 
 ###### `new UrlAssembler(urlAssembler)`
+
 - `urlAssembler`: an existing instance of `UrlAssembler`
 - this constructor is used for chaining internally. You should be aware of it if you extend `UrlAssembler`
 - **returns** a new instance of a URL assembler, copying the previous one
 
 ###### `.template(template)`
-- `template` a *string* with dynamic part noted as `:myparam` . For example `'/hello/:param/world'`
+
+- `template` a _string_ with dynamic part noted as `:myparam` . For example `'/hello/:param/world'`
 - **returns** a new instance of `UrlAssembler` with this template configured
 
 ###### `.prefix(subPath)`
-- `subPath` : this *string* will be added at the beginning of the path part of the URL
+
+- `subPath` : this _string_ will be added at the beginning of the path part of the URL
 - if called several times, the `subPath` will be added after the previous prefix but before the rest of the path
 - **returns** a new instance of `UrlAssembler`
 
 ###### `.segment(subPathTemplate)`
-- `subPathTemplate` is a *string* of a segment to add to the path of the URL. It can have a templatized parameter eg. `'/user/:user'`
+
+- `subPathTemplate` is a _string_ of a segment to add to the path of the URL. It can have a templatized parameter eg. `'/user/:user'`
 - if called several times, the segment will be added at the end of the URL.
 - **returns** a new instance of `UrlAssembler`
 
 ###### `.param(key, value[, strict])`
-- `key`: a *string* of the dynamic part to replace
-- `value`: a *string* to replace the dynamic part with
+
+- `key`: a _string_ of the dynamic part to replace
+- `value`: a _string_ to replace the dynamic part with
 - **returns** a new instance of `UrlAssembler` with the parameter `key` replaced with `value`.
-If `strict` is falsy, the key will be added as query parameter.
+  If `strict` is falsy, the key will be added as query parameter.
 
 ###### `.param(params[, strict])`
-- `params`: a *hash* of key/value to give to the method above
+
+- `params`: a _hash_ of key/value to give to the method above
 - `strict` a flag passed to the method above
 - **returns** a new instance of `UrlAssembler` with all the parameters from the `params` replaced
 
 ###### `.query(key, value)`
+
 - `key`: the name of the parameter to configure
 - `value`: the value of the parameter to configure
 - **returns** a new instance of `UrlAssembler` with the `key=value` pair added as
-query parameter with the [`qs`](https://www.npmjs.com/package/qs) module.
+  query parameter with the [`qs`](https://www.npmjs.com/package/qs) module.
 
 ###### `.query(params)`
+
 - shortcut for the previous method with a hash of key/value.
 
+###### `.configQs(params)`
+
+- add config supported by qs.stringify https://www.npmjs.com/package/qs version ^6.5.1
+
 ###### `.toString()`, `.valueOf()`, `toJSON()`
-- **returns** a *string* of the current state of the `UrlAssembler` instance. Path parameters not yet replaced will appear as `:param_name`.
 
-Test
-----
+- **returns** a _string_ of the current state of the `UrlAssembler` instance. Path parameters not yet replaced will appear as `:param_name`.

+## Test
 
 Tests are written with [mocha][mocha-url] and covered with [istanbul][istanbul-url]
 You can run the tests with `npm test`.
