mongoose-integer is a plugin to validate integer values within a Mongoose Schema.

I was really tired of casting or validating my Number fields to an integer value. So I created this easy-to-use plugin that takes all the work from you.

npm install mongoose-integer

Then, simply apply the plugin to your schema:

var mongoose = require('mongoose');
var integerValidator = require('mongoose-integer');

var mySchema = new mongoose.Schema({
	value: {
		type: Number,
		integer: true
	}
});

mySchema.plugin(integerValidator);

You can pass through a custom error message as part of the optional options argument:

mySchema.plugin(integerValidator, { message: 'Error, expected {PATH} to be an integer.' });

You can also pass a specific error message as a string in your field declaration:

var mySchema = new mongoose.Schema({
	value: {
		type: Number,
		integer: 'Value must be an integer.'
	}
});

You have access to all of the standard Mongoose error message templating:

• {PATH}
• {VALUE}
• {TYPE}

To run the tests you need a local MongoDB instance available. Run with:

npm test
