I am creating a very big Angular library. Because I have many classes and components, I have structured them in a hierarchy. For example, I have: Map Panels Toolbar MainPanel Etc. Layers BingLayer WMSLayer WMTSLayer Geometries Point Line Polygon etc. In the public_api.ts, I have many exports, one for each component/module/service I want to expose on the library, but this flattens my hierarchy. The only way I found to maintain the hierarchy is to create a library for each group on the hierarchy tree. For example, a library for Panels (Panels-lib), a library for Layers (Layers-lib) etc. and then replicate the hierarchy on the file system putting each library in a separated folder: a folder for Panels, a folder for Layers etc. In this way, in the main application I can import components in this way: import {ToolBar} from "MyMap/Panels/Panels-lib"; import {Line} from "MyMap/Geometries/Geometries-lib"; Is there a better way to achieve this? Thank You in advance. Continue reading...
