This material continues the cycle about assembling Docker images for applications in various programming languages ​​using the utility dapp . Previous article was about building applications in Java - now let's talk about applications in jаvascript. For starters, this will be a frontend application, and in the next part it is planned to tell about the assembly of the backend and the launch of everything in Kubernetes.
 
 
As an illustration, the applications will be used. nodejs-pool and ...

The article presents (and is demonstrated in short video clips) a toolkit that facilitates the development and debugging of configurations with dapp - Open Source-utility, which we use daily for building and maintaining CI /CD processes.
 

 
Note
: Recently, the support for the YAML syntax in dapp has been announced, the features of which can be read in of this publication . By default, all the tools described below will be valid for both it and the configuration in Ruby DSL (used in previous versions of dapp), and if it is not, it is specified separately.

Windows has long been reproached for the slowness of its file operations and the slow creation of processes. Why not try to make them even slower? This article will show how to slow down file operations in Windows by about 10 times from their normal speed (or even more), and these methods are practically not amenable to tracking by a normal user.
 
 
And, of course, we will learn to detect and correct such situations. The whole text is written on the basis of the problem I encountered a couple of months ago, so everything written below is completely real.

Imagine that Roskosmos decided to assemble a new rocket without having drawings and a clear understanding of how the missile should be arranged. A separate plant is engaged in the missile body, a separate engine produces engines, another one - nozzles. The chief manager of Roskosmos said that he trusts professionals, and expertly delegated all the work to the factories.
 
 
 
 
A year later all the components are delivered to the main assembly shop, and it turns out that the engine does not enter the housing, and the nozzles begin to melt even when the engine starts up.
 
 
To prevent such a thing, real ...

Earlier this year, we decided that our Open Source-utility for supporting CI /CD processes - dapp version ??? - has a sufficient set of functions and work was started on innovations. In version 0.2? the syntax of YAML appeared, and Ruby DSL was declared classic (it will no longer be supported at all). In the next version, 0.2? the main innovation can be considered the appearance of the collector with Ansible. It's time to tell more about these novelties. dapp more than 2 years and actively use in everyday maintenance of many projects of different scales. The first versions of the utility were ...

February 2? 2018 released the release of webpack ??? (and to date, ???). One of the useful and relatively new features webpack - code splitting , transferred to the new version of the plug-ins into the main configuration. With almost no documentation, how now it is necessary to configure code splitting in version 4 - I was a little shocked, but still tried to gather information in order to start working with the new version at least. I hope that after a while there will be extensive tutorials and articles. In the meantime, I hasten to make notes on the information found, so as not to lose ...
