Developing Concurrently on 4D Server in Project Mode

Automatically translated from English

Since its release in 4D v18, Projects drastically expanded 4D’s capabilities by bringing compatibility with version control systems —among other things.

With excellent feedback, we couldn’t be prouder to see significant adoption of this feature among the 4D community. This pushed us to improve it to make it even better. 

Your feedback included a request for the possibility to work simultaneously on a single development server as a team. Again, 4D listened, and we are thrilled to announce that with 4D v19 R6, you can work on a development server in project mode!

4D and Git: From Beginner to Expert

Automatically translated from English

So by now, you know that projects come with a tremendous benefit: the ability to use Git (the revision control system) and GitHub (the hosting service) to get your 4D application up and running in a more productive development environment.

Newbie or full-fledged senior developer version control has been a staple in every work environment where multiple resources collaborate to participate in what could be called a software chain of production.

To help you get familiar with Git, we’ve made available many resources at your disposal. This blog post is a compilation of everything we’ve provided on this topic… so far. If you feel lost and don’t know where to start, keep reading; we’ve included:

  • other blog posts,
  • a detailed guide,
  • a top-rated summit video,
  • and even a training course.

Directory file management in merged server projects

Automatically translated from English

Projects introduced the new directory.json file containing users, groups and permissions. It allows authentication, restrictions, permissions on several parts of the application, through settings or code. Let’s see the new improvements about this file usage in merged server projects.

Saving project source code without tokens

Automatically translated from English

Commands, constants, tables and fields are stored with their tokens in the project source code files (4dm files). This allows 4D to rename them automatically. But sometimes, you would like these source code files to be stored without tokens for a better readability with a version control system or an external code editor, or for better code sharing between projects. Let’s see how to make 4D store source code without these tokens.

Quickly jump to different functions of a class

Automatically translated from English

Classes were introduced with 4D v18 R3. They allow you to organize your business logic and separate it from the UI part more quickly.

Classes are composed of several functions of varying lengths, so it’s not always easy to find the function you want to modify, or to move from one function to another. You can use the explorer, which displays classes and functions, but when you’re coding in the editor window, you don’t want to waste time changing windows.

With 4D v19 R4, the list of functions in your class is displayed in the code editor toolbar, allowing you to easily jump to a specific function.

An introductory guide to 4D and Version Control Systems

Automatically translated from English

For many years, 4D has allowed you to develop binary databases as part of a team with a 4D Server. This way of developing is straightforward, but many developers asked us to be more efficient on source code management to deliver better traceability. 4D has heard them and developed Project mode to fit this need. This mode opened a new era of collaboration thanks to version control systems!

4D REST API + ReactJS

Automatically translated from English

by Mourad Aouinat, Software Engineer at 4D Morocco

In a previous blog post, we saw how easy setting up a REST API using 4D. In this blog post, we will leverage the powerful 4D REST API in combination with React to build a To-Do app that includes features to open todos, create new ones, modify existing ones, and features for bulk modification and bulk deletion.

How to automate the compilation

Automatically translated from English

Since 4D v19, you can start the compilation of a project with a simple command. You might be wondering what you can use this for!

Your team may consist of several developers, so why not automate the compilation at each code push on your source control server? It is always easier to identify an error when it is quickly detected.

Another case is when your project consists of several components. You can write a method that compiles, builds, and then copies the component to the host database.

This blog will discuss the different technical points that are very useful to create your own automation tools, along with an example application.
