The goal of this project is to demonstrate how to incorporate Exadel Smart Library into a JavaScript project using Babel compiler and to demonstrate how to overcome the problem of decorators support.
Note If you want to utilize the syntactic sugar offered by Exadel Smart Library, it is essential to have a compiler that supports TypeScript experimental decorators. However, even if your compiler lacks this support, the functionality provided by ESL will remain intact.
In order to enable full support for decorators, it requires to have a Babel config file configured with the necessary plugins: @babel/plugin-proposal-decorators and @babel/plugin-proposal-class-properties.
"plugins": [ ["@babel/plugin-proposal-decorators", {"version": "legacy"}], ["@babel/plugin-proposal-class-properties"] ]
ESL decorators are based on experimental decorators, defined at wycats/javascript-decorators@e1bf8d41bf. This is why decorator's version must be set to legacy.
Proposal class properties is a plugin that transforms static class properties as well as properties declared with the property initializer syntax. While the "@babel/plugin-proposal-class-properties" plugin is not mandatory for decorators support in general, it becomes crucial when utilizing specific decorators such as jsonAttr and attr.
