nginx configuration index.html different path

Question

I'm going crazy with the nginx configuration.

I have this directory tree site

|-- .tmp
|    +-- partials
|    |    |-- partial.js
|    |    |     
|    +-- serve
|         +-- app
|         |    |-- app.css
|         |
|         |-- index.html
|
+-- libs
|    +-- folder_a
|    |        
|    +-- folder_b
|
+-- transpiled
|    +-- app
|    |    |-- app.js    
  

Also in my index.html I have the paths like

<script src="../bower_components/jquery/dist/jquery.js"></script>
<script src="app/app.js"></script>

So, if I'm right, my root should be the transpiled directory.

What is a valid nginx configuration for serving my site ?

conf example added

 http {
    server {
          
       location / {
           root html/my_site;
           index .tmp/serve/index.html;
           try_files $uri transpiled/$uri;
       }
    }
}

I don't know nginx but i have read something about try_files. try_files directive should search the file $uri into transpiled/$uri. So if i have app/app.js try files should search the file in transpiled/app/app.js

This won't work
