HTML Forms & Validation

2016-11-26 12:00 PM (4 years ago)

This release is huge. We have been working on it for more than 3 months now. The last released version of Spincast contained approximately 800 tests, there are now over 1600!

The core of this release is about HTML Forms and Validation. There's a lot more than that, but those are the two big novelties.

Spincast supports Json and XML out of the box since day one, so developing a Single Page Application or a set of REST services has always been easy. But, even if SPAs are very popular these days, any serious web framework must provide excellent support for traditional websites too, where the server generates the HTML to render.

As long as you integrate a good Templating Engine, providing HTML generation functionalities is not too hard. What's more challenging is to provide a good experience when it's time to deal with forms and their validation... And we think we hit the nail on the head! Spincast now provides an easy way to validate a submitted form and to redisplay it with Validation Messages resulting from the validation, when this is required.

Another big change in this release is about JsonObjects : they are now more powerful than ever and they are used pretty much everywhere in Spincast. We added to them a feature we call JsonPaths : this makes retrieving an element, inside an element, inside an array, inside an element, as simple as :

Date myDate = myJsonObject.getDate("user.books[3].publishingDate").

We also added a small Quick Tutorial section which is a high-level view of the main steps involved when building an application using Spincast. And, finally, we cleaned a lot of code, which now follows more closely Java's standards (no more "I" prefixed interfaces!).
