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
