Question

Write a node express EJS application that computes the area of a triangle. On RESET the application begins again. Assume, Base and Height are decimal numbers.

Answer 1

To write a Node Express EJS application that computes the triangle area, set up an Express server, create an input form in EJS for base and height, write a POST route for form processing, compute the area, and render the result. Include a reset feature to allow the application to start over. Test thoroughly for accuracy in computations and reset functionality.

Step-by-step explanation:

Building a Node Express EJS application that computes the area of a triangle involves several steps. First, set up an Express server and create a form in EJS to input the base and height of a triangle. Then, write a route that processes this form data, calculates the area using the formula Area = 0.5 * base * height, and renders the result back to the user. Lastly, include a reset button in the EJS file that allows the application to start over.

1. Initialize a new Node.js project and install Express and EJS.
2. Create an Express server with a route to serve the form.
3. Design a form in an EJS file with fields for base and height, and a submit button.
4. Implement a POST route to handle the form submission, performing the area calculation.
5. Respond with another EJS file showing the calculated area and a reset button to restart the process.

The key is to ensure the application handles decimal inputs for the base and height, accurately performs the computation, and uses EJS to dynamically display the result and reset the form.

Remember to test the application thoroughly to ensure that it correctly computes the area for various inputs and resets as expected.
