🔌 Mongoose to Express-Validator adapter

This package converts Mongoose schema into a validation chain for Express. Currently, it supports most default schema types as well as a few custom ones. For instance, schema types named Email or Phone match validator's implementation. See the full list of supported properties below.

The plugin

This module works through a custom Mongoose plugin that appends two static methods, getSchemaPaths and getChildPaths. Both work recursively and support child and discriminator schemas. To access a discriminator, though, the request object must contain a reference to its key. See the examples below for more detail.
