Author

This class can authenticate and autocomplete street addresses.

It sends HTTP requests to the streetLayer API Web server to perform several functions:

1. Authenticate an address to verify that it really exists

2. Provide autocomplete text options to an address partially entered

3. Reverse search to addresses close to a geographic location

Many sites need to request users to enter their postal addresses, like for instance in ecommerce sites. This may be a tedious task for the user, especially those that do not like to type on mobile devices.

Often users give up registering or buying a product when they need to fully enter their postal addresses on forms. So bureaucratic form filling may cause loss of customers.

This package provides a solution to minimize the pain of the users that need to enter postal addresses in forms. It provides means to autocomplete an address partially entered by the user in a Web form.

When used in conjunction with AJAX requests, it can autocomplete the address while the user is typing in on the form without having to reload the current page.

The possibility to validate if an address is correct is also very useful as it may avoid problems of delivering goods to addresses that are incorrect.
