MemoryConfigReader class
Config reader that stores configuration in memory.
The reader supports parameterization using Handlebars template engine: Handlebars
Configuration parameters
The configuration parameters are the configuration template
See IConfigReader
Example
var config = ConfigParams.fromTuples([
'connection.host', '{{SERVICE_HOST}}',
'connection.port', '{{SERVICE_PORT}}{{^SERVICE_PORT}}8080{{/SERVICE_PORT}}'
]);
var configReader = new MemoryConfigReader();
configReader.configure(config);
var parameters = ConfigParams.fromValue(process.env);
var config = await configReader.readConfig('123', parameters)
// Possible result: connection.host=10.1.1.100;connection.port=8080
