mongo-comparison-ops-description v1.3.0

mongo-comparison-ops-description

This library will create a Mongo-style regex from a "description" (a tuple of an operator and a value). This is useful for building UIs on top of Mongo or Sift $regex operators.

Also see https://github.com/mixmaxhq/mongo-regex-description for the text counterpart to the library.

Example:

var comparisonDescription = require('mongo-comparison-ops-description');

var regex = regExpDescription.create({
	operator: 'equal to',
	value: 1
});
// { $not: { $regex: '^my value$', $options: 'i' } }


var description = regExpDescription.parse({
	$not: {
		$regex: '^my value$',
		$options: 'i'
	}
});
// { operator: 'is not', value: 'my value' }

Supported Operators

• equal to
• greater than
• greater than or equal to
• less than
• less than or equal to
• not equal to
