jsont

JSONT is an extension to JSON that lets you use templates.

JSONT's syntax extension is simple:

  • anything of the format $[var] is replaced with the value of var.
  • anything of the format $[date:now] calls the corresponding library method you supply it with.

date (JS Date) and oid (BSON ObjectID) are inbuilt library methods. The available calls are:

  • date:now
  • data:+1h
  • data:-1d
  • oid:new
  • oid:5b912a771c9d44580b1c5915

Usage

const JSONT = require('@codefeathers/jsont');

const env = { '1': 'hello' };

console.log(
	JSONT.toJSON(
		JSONT.parse(
			'{ "sample": "$[1]", "now": "$[date:now]" }',
			env,
		)));

Remember, the parsed template will still be a string. You have to use .toJSON or JSON.parse to parse it into an object.
