The default pattern property shouldn't by default take action unless the input value is undefined. An additional option named replaceNull should be able to be set, in which null is also replaced by the defined default value.

Currently the flags used for regex checking are set by the library and cannot be changed. A regexFlags property could be useful in various cases.

Implement an array type for all currently implemented datatypes.
Also the properties that can apply for those types should be checked for any element in the array

The documentation of expressjs-check is missing the object type.

The possibility to use a if for all properties that exist, e.g. min, max, minLength, maxLength, pattern, ...

It should still be possible to pass a normal value that should always be used, for example:

testNumber: {
	required: true,
	type: 'number',
	min: 10
}

It should also be possible to pass an array instead of a value that applies one/multiple options, for example:

testNumber: {
	required: true,
	type: {
		if: '3 === 3',
		value: 'number'
	}, 
	min: [{
		value: 5,
		ifCondition: '#minNumber === 5'
	}, {
		value: 10,
		ifCondition: '#minNumber === 10'
	}, {
		value: 0 // without an if property it works like ifCondition was true (effectively an else condition)
	}]
}

In the same structure as stated in #7 add a property customError: string and customStatusCode: integer.

Also only one error message (the first that occurs) should be included.
Example usage:

It should also be possible to pass an array instead of a value that applies one/multiple options, for example:

testNumber: {
	required: true,
	type: {
		if: '3 === 3',
		value: 'number',
		customError: 'Not a number',
		customStatusCode: 409
	}, 
	min: [{
		value: 5,
		ifCondition: '#minNumber === 5'
		customError: 'Not greater than 5',
		customStatusCode: 400
	}, {
		value: 10,
		ifCondition: '#minNumber === 10'
	}, {
		value: 0 // without an if property it works like ifCondition was true (effectively an else condition)
	}]
}

Currently it's only possible to set minimum and maximum length for strings, however, it may be useful in some cases to only allow a fixed length of characters for a string.

Checking for the regex ([0-1][0-9]|2[0-3]):[0-5][0-9] yields incorrect results. This is possibly due to issues regarding regex groups, as the checker may be checking for the group match rather than a full match.

A default property that is set on the object when the property is not specified/undefined.
For example:

testNumber: {
	required: false,
	type: 'number',
	min: 10,
	default: 15
}

If the proerty testNumber is not provided/undefined it is set to the value 15.

The type must be set to date to use this property.
Default value is false.
If this property is set to true and the string passed can be parsed it is replaced by a date object of the string.

Comparing values to undefined using the === operator ends up never making the parameter required.
