In this tutorial, we will go over how to make changes to content schema in a DatoCMS project safely, without interfering with production, and with maximal flexibility for testing before merging.

At Cantiere Creativo, we are proud to be the place where DatoCMS was born, and we use Dato in a vast majority of our projects. In early 2021 Dato launched a revolutionary new feature that greatly enhances the experience of editors while inserting and managing content. In this post, we're going to walk through all you need to know as a developer to start using Structured Text in your website today.

As we continue to work more and more with Elixir and Phoenix, there is a growing number of features we have implemented in this framework to suit specific needs we have come upon.

Recently, we had a problem with flash notification messages in LiveView and decided to implement our own way of issuing notifications throughout an application using PubSub instead of live flash, not just to solve the bug but also to have greater flexibility and control over the notifications system.

Here at LeanPanda, we were delighted to see the new website of the Department for Digital Transformation of the Prime Minister’s Office go online last 4 February. It made us proud as both citizens and professionals. 

Lean Panda is currently developing a number of Elixir applications using Phoenix LiveView. Working with LiveView is a pleasure, but we still have some unsolved situations, or, at least, we don’t have a standard way of solving them. One of those problems is authentication and authorisation: authentication is where you prove who you are and authorisation is where the application decides what you can do.

On this article, we implement authentication and authorisation in Liveview, explaining the code and our decisions.

One advantage of React is the clean modularity of its components. While most React sites are dynamic single-page applications, the modularity React offers means that it is also used in static sites.

The first big static site generator that used React was Gatsby, but now the new cool kid on the block is Next.js. How does it fare?

In this article we are going to walk through our last two years experimenting Lean UX with more than 80+ clients.

Hot topics: Our way of selling Lean UX and the importance of marketing in UX.

Let's go! 👉

If forwarding emails (with some calculations in-between) is what you need, then AWS Lambda is the simplest solution for you.

We are an agency with several clients and have fallen in love with Lean UX. But one of our first feelings was that Lean UX is perfect for one-product-focus teams.

What about us, agencies and freelancers?

We are now going to cover everything concerning the kick-start phase of a project as soon as a client gets in touch, and with the determination to do it following Lean UX principles and methodology.

The world of Javascript is currently characterized by extreme fragmentation and intense competition between different ideas. This has caused us to ask ourselves a couple of questions. Firstly, is this proof of the community's vitality, or of its immaturity? Secondly, how is it possible to survive the current churn rate?

In this new series of articles we will do our best to clearly explain what the different alternatives available to those working with Javascript are, and to set out our ideas about what constitutes solid, maintainable development.

Angular is now, without doubt, the Javascript Framework par excellence®, with popularity far exceeding that of any of its competitors. But is all that shines really gold? In this latest post in our #BazarJS series, which looks at the development of Single Page Applications, we will describe our personal experience with the framework.

How is it possible to make automatic classification work properly without resorting to using external prediction services? Starting with Bayesian classification, you can use the ruby gem classifier-reborn to create a Latent Semantic Indexer. Hands on!

Our BazaarJS series continues. In this article we're going to take a brief (digestive, if you will) pause from the world of Javascript to confront another, equally important, topic: stylesheets. Based on our extensive experience with Sass, we will examine the principle Javascript alternatives available (Less.js and Stylus). Is it worth changing preprocessor? To finish, we will take a look at a range of postprocessing tools that have grown in popularity during 2014.

Over the years we have found that there are huge advantages to testing. However, we have also found that the process brings with it certain problems, some of which are not easily solved. One of these is explaining the value\cost of testing to clients, and deciding whether to confront the issue during the sales phase.

If you're using Rails then managing the SEO component of a web application is as simple as it is important to implement. You can easily find guides on how to do so online.

This is the second episode of our BazarJS series on the magical world of single-page applications... today we're going to be taking a serious look at module loaders, bundlers and package managers: three of the most "confused", controversial and peculiar topics in the Javascript world.

As always, after giving an overview of the available solutions, we will explain the advantages and disadvantages that have led us to our personal choice.
