** Example config file **

actuator:
    prefix: /actuator
    paths:
        info: /info
        health: /health
        metrics: /prometheus
        logger: /logfile
application:
    name: App name
static:
    path: /
    src: ./public
logger:
    level: info
    filename: app.log
    postPath: /logger
proxies:
    - path: /api
      target: http://localhost:8080
      logLevel: info

Configuration

Must include a config file.

Actuator

This comes from spring boot. The intention is to provide some basic information about the app and some typically useful access points.

• prefix is the leading path for access the rest of the actuator endpionts
• paths.info endpoint for getting info details. This will return a json value of everything in the applciation property. IT will be converted to a JSON object and returned.
• paths.health endpoint for getting health response. Health endpoint will return {"status":"up"}
• paths.logger endpoint to view the logfile that is created by the app.
• paths.metrics endopoint to view the prometheus metrics for the app.
  The metrics are accomplished by using prometheus-api-metrics

Application

This can be any properly formatted yml. It will be converted to a json object and returned to the /acuator/info endpoint

Static

Config for serving static html/js content

• path is the endpoint that the static files will be served from.
• src is the relative path the static files are located in.

Logger

Configuration for logger of the express application. Uses winstonjs.

• level log level
• filename if this is present the application will also write log messages to a file. It will also be what is returned when accessing the /actuator/logger endpoint.
• postPath is the path used to post a log message to. Can be used for external logging of a SPA.

Proxies

Configuration of reverse proxies created. This is accomplished by using the http-proxy-middleware. It is a list of proxies.

• path path the proxy is accessible from.
• target target for the reverse proxy.
• logLevel log level set for the revers proxy.
