Set up Microfrontends served from OpenMRS server

If you're just getting started with OpenMRS SPA, please first set up a local development environment.

Setting up Microfrontends

1. Install openmrs-module-spa on your OpenMRS server
2. Create a directory, in which we will create a packmap package (see the following instructions). You'll probably want to make it a github repository, like this one.
3. In this directory, create a package.json based on the packmap OpenMRS example

4. npm install

5. npm run build

6. Symlink* the resultant openmrs/frontend directory into your OpenMRS server's application data directory as "frontend". For my SDK server named "foo", on Linux, I do

     ln -s $(realpath openmrs/frontend) ~/openmrs/foo/frontend

7. Start the OpenMRS server

8. Navigate to localhost:8080/openmrs/spa/login (assuming your server is at localhost:8080)

9. If the page comes up blank...

   1. Open the browser developer console (probably Ctrl+Shift+i)

   2. Work through the errors with the Troubleshooting Guide

At this point, you should have microfrontends working entirely offline!

Adding configuration and assets without a custom root config

You can configure your application in the following manner

1. Create a directory in your packmap package directory called "assets"
2. Create a config.json file in that directory

3. Add the command*
       ln -s $(realpath assets) openmrs/frontend/ 
to the build script in package.json (separate it from previous commands with a &&)

4. Add the following line to your override-import-map.json

       "config-file": "/openmrs/frontend/assets/config.json"

5. That config file can refer to things you put in that assets directory, which will be served under  localhost:8080/openmrs/frontend/assets/

Developing on modules

TODO

*Sorry Windows users. Maybe one of you can fill in the equivalent thing to do here?
