Which IDE does the speaker choose for the project?
-The speaker chooses Visual Studio Code (VS Code) as their IDE for the project.
What are the two essential files the speaker creates for their application?
-The speaker creates an app.js file and a test.js file for running and testing their application.
Which framework does the speaker decide to use for their application?
-The speaker decides to use the Express framework for their application.
What packages does the speaker install at the beginning of the project, and how does Duet AI assist with this?
-The speaker installs the Express and EJS packages at the beginning of the project. Duet AI assists by providing the necessary command to install these packages, including the option to install them locally using the --save argument.
How does Duet AI help with initializing the EJS templating engine?
-Duet AI helps by recommending the boilerplate code for initializing the EJS templating engine in-line when the speaker writes a request in a comment and hits Control Plus Enter.
What is the purpose of creating a 'views' directory and what files does it contain?
-The 'views' directory is created to contain the templates for the application's pages. It includes an 'index' page with a form asking for a name and a 'greeting' page that uses the data from the form to greet the person.
How does the speaker test their application locally?
-The speaker uses the 'npm start' command to test their application locally, which opens up their browser to the index page on Local Host Port 3000.
What testing framework and package does the speaker use for unit testing?
-The speaker uses the Mocha testing framework with the Super Test package for unit testing.
How does Duet AI assist with deployment to Google Cloud's Cloud Run?
-Duet AI provides a sample command for deploying directly to Google Cloud's Cloud Run, including specifying the US Central 1 region and allowing unauthenticated invocations for the test application.
What does Duet AI do to help the speaker understand the logs produced by their application on Cloud Run?
-Duet AI helps by taking a log entry and explaining it in a few bullet points, making it easier for the speaker to focus on addressing the issues in the logs rather than translating them.
