usingEnvironmentVars(Optional interval)

Adds a EnvironmentVarsResolver with given config file to the LivelyConfig and will poll the environment vars if interval is given

usingFile(String filePath, Optional interval)

Adds a FileSystemResolver with given config file to the LivelyConfig and will poll the file if interval is given

usingHttp(String url, Object Headers, Optional interval)

Adds a HttpResolver and will call the url with headers and will poll the file if interval is given

usingObject(Object config, Optional interval)

Adds an ObjectResolver and use the provided config objects

finalize()

Locks the Resolvers list and will trigger the ready promise after all resolvers have resolved at least once

using(Resolver resolver)

Resolver (abstract)

Resolvers are how configs are loaded into the LivelyConfig, out of the box there are 2 concrete implementations (FileSystemResolver and HttpResolver), you can make your own by inheriting from the Resolver Class provided and implementing a resolve method.
