 ```purescript
 main = launchAff $ do
   res <- affjax $ defaultRequest { url = "/api", method = GET }
-  liftEff $ trace $ "GET /api response: " ++ res.response
+  liftEff $ log $ "GET /api response: " ++ res.response

 (`defaultRequest` is a record value that has all the required fields pre-set for convenient overriding when making a request.)
