A Node.js app using Express and deployed to Heroku.
This application uses Node.js and Express to create a web application that determines the postage required for a single piece of retail first-class mail. It has a form that allows a user to specify 1) the weight of the item and then 2) select one of the following types of mail:
- Letters (Stamped)
- Letters (Metered)
- Large Envelopes (Flats)
- Parcels
After submitting the form, the user is taken to a page that displays the information they submitted along with the resulting price.
The rates can be found on this page from the USPS.
