iFact: Developing a Webix-based invoicing application

The initial task

My objective was to design and implement a simple application allowing me to manage my freelance business. The application is called iFact and is available on github. The basic activity consists in getting contracts with clients, performing the work or service and invoicing the client. Also, I needed to manage the invoice flow and to have a minimal dashboard for cash flow control. The volume of invoices is low: from one to a couple of invoices per month. The number of clients and contracts per client is low, it means 5 to 10 clients with 1-3 contracts per client, normally one single contract active at any given moment in time.

Using reCaptcha in the Webix Form

Bots are around us. Some of them are good and they help us in everyday tasks, but some are evil and attempt to steal our information. If you are familiar with web development and forms, in particular, you may have faced certain security issues like abusive form input from bots. Measures need to be taken to make your website or web application safer, and using reCaptcha is one of them. Despite Webix does not offer such a widget of its own, there is a solution to it.

Let’s take a closer look at this way of protecting websites and web applications from spam and abuse. I will not discuss the server side of reCaptcha validation in the article, I will only show you the client side logic.
