griffon – rich app using groovy and swing

In my constant search for rich app platforms, griffon has appeared on the radar. Griffon (http://groovy.codehaus.org/Griffon) uses grails-like thinking to help you create an application. It includes plugins that bolt on large components into your application such as different builders and java components for web services. While it is still a young project, it looks promising and I encourage people to start using it and developing with it.

One are of development is to get spring and gorm moved over to griffon so that ORM technology is more easily available inside groovy similar to what is available in grails. You can use the 0.3 snapshot to create a spring enabled griffon application and if you compile the 0.3 snapshot compatible only gorm plugin (and manually install it), you can use gorm as well.

Recently, gorm was enhanced so that it could be used outside of grails, however, you must use a specially configured session factory that knows it should scan the domain classes and augment them with groovy special methods (so that gorm is easier to use for programmers).  This is documented http://www.integrallis.com/blog/tag/gorm and http://www.grails.org/1.1+Release+Notes. Some previous blogs which described how to configure stand alone gorm to scan the classpath and augment domain classes may no longer be valid as alot of this startup is done inside the special gorm session factory now.

IDE support is improving. I believe that the latest netbeans and intellij have support for griffon projects and similar to grails, requires issuing external commands to run griffon scripts such as “run-app.” Eclipse has groovy support but does not have griffon support per se and its not clear that anyone is working on eclipse griffon support beyond some basic integration. However, creating a griffon project creates an eclipse .project, .classpath and .launch file to help in editing and launching griffon programs. One problem, however, is that jar files in the .classpath are not pointing to the plugin jars and hence, incremental compilation may not work correctly.

quick note on scala.js, react hooks, monix, auth

quick note on scala.js, react hooks, monix, auth Reactjs hooks finally came out of preview in a recent version of React. scalajs-reaction has had support for hooks since they were in preview. React hooks seem like the hot new thing but for me the question is, do hooks help improve your code by improving maintainability, time to market, TCO, etc.? Let’s take a look using authentication as an example and employ monix , a reactive observable framework that also builds on cats . We will assume we are building a SPA. Does it improve your code and make your application & development experience better? Auth Auth processing can be complex. Many react auth examples you find in blogs like to show how to use “react-routing” and “auth” as a switch that determines which routes are protected or unprotected. Protected routes show application specific data. Unprotected routes show login content . Based on storing a “User” object in the browser session/local storage, th

zio environment and modules pattern: zio, scala.js, react, query management

zio environment and modules pattern: zio, scala.js, react, query management This blog covers a zio-based fetch design for scala.js, react web applications. It heavily uses the zio “environment” feature to help motivate a point of view on the modules pattern in effect systems. At the end, I summarize some thoughts on ergonomics and complexity. This blog assumes a basic knowledge of zio and react. scala.js is just like scala so you mostly already know scala.js. This blog is a follow-on to previous blogs: https://appddeevvmeanderings.blogspot.com/2019/10/scalajs-react-fetcher-hook_48.html and https://appddeevvmeanderings.blogspot.com/2019/11/scalajs-and-react-suspense.html . I have been keeping an eye on and culling ideas from typscript/javascript fetching libraries that address query management concerns. The formulation below incorporates some of those concerns but does not try to comprehensively duplicate well established javascript libraries. I only care about

user experience, scala.js, cats-effect, IO

user experience, scala.js, cats-effect, IO This is not a complicated snippet but I wanted to ensure I remembered it. When creating a UI, say react for browsers, you will run into the “fetch” data problem. When you fetch data, you typically have a component that performs the fetch and acts as a cache for the result. The fetch component renders a child and passes along the data that was fetched (or the fetch state, etc.). Even with the upcoming react suspense mechanism that will make this a smoother user experience, you may have a flash of a “loading” indicator that shows for a moment before the content is fetched from the server. If the flash is too fast, it is visually disruptive. A shimmer mechanism for the UI my also not be the answer. Similarly, if the fetch request takes too long, you will want it to time-out and show an error message that the data could not be fetched or whatever is appropriate for feedback in your application. Generally, I use cats-effect
