Simple Angular5 project that reads a external file with properties before the bootstrap.
There are not many examples of reading external files before the bootstrap, much less using version 5 of Angular.
Usually people are content with reading the properties of environment.ts and environment.prod.ts but, once the project is built, these files are integrated into the generated .js files.
If you want to change a property you have to rebuild the project.
That's why this example shows how to get a property from an external file, located in the server but decoupled from the rest of the code.
This project was generated with Angular CLI version 1.6.5.
Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.
Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the -prod flag for a production build.
