Allows for template strings inside of node-convict
configurations with one additional line of code allowing you to define configuration values
in terms of other configuration values.

Install

`

Usage

$3

The template type can be added to a convict schema as shown in the example and
the value will be replaced when calling the replaceTemplateValues function.

Example:
`
import convict from "convict";
import templateFormat, { replaceTemplateValues } from "convict-template-format";

convict.addFormats(templateFormat);

const config = convict({
deployment: {
format: String,
default: "staging"
},
appName: {
format: "template",
default: "app.${deployment}"
}
});

replaceTemplateValues(config);

config.validate();
`

Templates can reference nested values as well as other template values:
`
const config = convict({
deployment: {
format: String,
default: "staging"
},
serverA : {
host: {
format: "template",
default: "https://servera.${deployment}.test.com"
},
health: {
format: "template",
default: "${serverA.host}/health"
}
}
});
``
