Webix UI VS jest

The next advantage of micro-frontends is that its adoption enables faster development and deployment. There’s no need to manage a large development team that has to deal with an extensive codebase. Instead, a small team of developers, independent from the others, can focus on a small list of features. It results in faster development, more efficient testing, and more frequent releases of new features. Some JavaScript UI libraries, such as Webix, for example are designed to make more with less code. If you combine micro-frontends with such dev tools, you can achieve even lower development time and cost. Also, applications based on the micro-frontend architecture are easier to maintain. A small team can focus on a single business requirement to implement, test, and maintain in the future. As a result, developers know their area of responsibility better and chances to get lost in the code as low as possible.

To finish projects on time, efficient time management is a must. To help managers deal with deadlines, we usually implement a fully functional Gantt chart. To create a reliable and user-friendly UI, choosing the right set of tools is essential. In our work, we usually rely on Webix, a JavaScript UI library developed by the brightest minds of XB Software. Another ace up our sleeve is JavaScript UI libraries by DHTMLX. Such an approach allows us to avoid dozens of possible errors since our developers use a tool they know every detail of. Moreover, Webix provides access to dozens of widgets whose out-of-the-box functionality enables a faster work pace and helps cut costs. Our clients, in turn, can be confident that their project will use a library whose support and continuous improvement will not be abandoned for the foreseeable future. Due to these features, we usually use a Webix Gantt as a basis for PM tools.

Webix UI is a JavaScript library that allows you to create a responsive design without worrying about the app's performance. The range of possibilities is represented by UI components of varying complexity. It can be a simple button and a complex solution. Each widget includes a whole set of methods and properties for flexible configuring and controlling. Besides, the library has extra tools. For example, event handling, methods of working with data, interaction with the server, styling themes and much more. You can find out more information about capabilities in the documentation. Now it is time to move on to the practice.

Since there is enough information on the web about open-source solutions, let's look at the library which is less popular but surely worthy of attention. Webix UI library has gained 4.8 out of 5 on Capterra. The library has been developed by XB Software since 2008. It is regularly updated, there is a blog with lots of reviews of the users. Many of them note the responsive support, the convenience of outsourcing services, and the speed and ease of building apps with the help of the Webix complex widgets. The downsides of the library mentioned are the documentation which is quite restricted and the lack of examples of combining Webix with TypeScript.

JavaScript/HTML5 File Manager – view demo The following components are used: DataView, Grid, Form, Layout, Menu, Popup, Tabbar, Toolbar, Tree, and Window. The features include uploading and downloading files, creating and deleting folders, grid and list preview modes, sorting and searching files, and keeping track of the space left.

In the article, we will discuss the components of the user interface and focus on their help in the JS development. If you are considering JS development as a career option, this overview may come up in handy for you. Seniors may turn to the second half of the article and study the opportunities of the Webix JS library.

There are several testing approaches you can take to ascertain the functionality of the auth API. One way would be to automate the testing using unit tests with tools like Jest and Supertest. Alternatively, you can make use of API clients like Postman or the Thunder Client VS Code extension to test the API.

Jest

you have selected a testing framework. In my case, it's Jest with Supertest

Jest, created and maintained by Facebook, is a JavaScript testing framework with a focus on simplicity. It is often recognized for its zero-configuration setup and seamless integration, especially with React applications, making it a favored choice for developers in both small-scale projects and large enterprise applications.

Jest (https://jestjs.io/)

console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation

Note: I will be using Jest as testing framework throughout the examples.

We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

Jest has long been my favorite got to test runner when it comes to UI unit and integration testing. With tools like React Testing Library (Testing Library framework for React) you get the benefit of very easy to write and maintain tests, as well as a quick and efficient way to run our tests.
