playframework - Use WSClient in scala app (play framework) -

i'm not sure if there's basic i'm missing, can't figure out how use wsclient. i've seen of examples saying need pass wsclient class dependency, i've done, when run program pass class?

for example, class signature is:

class myclassname(ws: wsclient) 

but when instantiate class pass it? i'm happy ignore play! framework stuff if makes easier , use sbt run (which i'm more familiar with).

it's unclear where might using wsclient, recommended let play framework 'manage' instance of client. when instantiate application, gets injected:

class application @inject() (ws: wsclient) extends controller {   ... } 

what means inside ... have access ws value. can instantiate myclassname using it:

class application @inject() (ws: wsclient) extends controller {   val myclass = myclassname(ws)  // passes injected wsclient myclassname } 

or can write function returns wsclient, other area of code can call application object object handler it.

but key application object gets handle because of injection, @inject annotation.

if need generate wsclient , manage manually, there good instructions here. recommended implementation reliant on play! framework libraries, doesn't depend on application.
