To test the app, from the root of the application folder, run this:

$ npm run dev
or
$ yarn dev

This will launch our application. From the home page, click on Create Thread and create a new thread named Translate API Test or any name you want. Once we create a new thread and navigate to the view thread page, we should see the translate button next to each text message:

Next, when we click on the Translate button, we should see a popup where we see the original message and a selection for translated language. When we pick a language and click on Translate, we should see the translated message, as shown here:

I have translated the text to Bengali.

In our application, we conveniently don't have an edit message feature. So, as long as the message is in our database, the translation is still valid. You can try other languages and test the complete flow end to end.

To wrap up this chapter, we are going to push the code to Heroku.
