Building a JSON HTTP Endpoint

The video tutorial guides viewers through setting up a web server project by integrating geocoding and weather forecast functionalities. It covers copying necessary files, installing dependencies, and implementing the geocode and forecast functions. The tutorial includes a coding challenge to wire up the weather endpoint and provides a detailed solution walkthrough, ensuring the endpoint returns real forecast data based on user input.

What is the first step in setting up the new project for the endpoint?

• Create a new directory for the project.

• Copy files from the Weather app project.

• Install the necessary NPM modules.

• Write new code for geocoding.

Which module needs to be installed to use geocode and forecast functions?

• Express

• Axios

• Lodash

• Request

What pattern is used to handle asynchronous operations in the Weather app project?

• Event loop

• Nested callback

• Async/Await

• Promise chaining

What should be done if an error occurs during the geocode process?

• Retry the geocode process.

• Send back an error response.

• Ignore the error and continue.

• Log the error to the console.

What is the purpose of destructuring in the geocode function?

• To avoid using callbacks.

• To improve performance.

• To handle errors more efficiently.

• To simplify the code by extracting properties.

How should the forecast data be sent back to the requester?

• Using document.write

• Using response.send

• Using alert

• Using console.log

What should be included in the response object if the forecast is successful?

• The raw data from the API

• Forecast, location, and address

• The error message

• Only the forecast data

What is the final step after implementing the geocode and forecast functions?

• Add more features to the application.

• Test the endpoint with different locations.

• Deploy the application.

• Optimize the code for performance.

What is the next step after testing the endpoint?

• Write documentation.

• Integrate it into the web application.

• Submit the project for review.

• Start a new project.

What format is used to send the forecast data back to the client?

• HTML

• XML

• CSV

• JSON
