I have an angular application (war format) that run on a jboss application server. My actual architecture is: Front app ( angular ) and back app ( java ), the front calls back services using the rest api link, that is provided in the src/conf/config.json file.
This is my app config file :

```
{
"restApiUrl": "https://jboss_host:8443/back/rest/",
"ldapAuthentication" : true
}

```

So, my needs for now ( the client need) is to externalize this config file to change the rest api link easily, without make a rebuild or redeploiment process.

I can't use any further elements in my architecture ( revers-proxy, conf server ) because it going to be a brain teaser for the client production, or api database ( the DB connection is provided by the back service ).

Please can you advise.
