Wibe Validator

It's a wrapper on top of JSON Schema Validator which should help you validate data match easier and faster without a need for any setup. Only two things are needed: schema and data.

How to use

Synchronous validation:

const WV = require('wibe-validator');
const validators = WV.Schemas.create({
  user: require('./path/to/user_schemas.json')
});

class UserResource () {
  static create(req) {
    const validation = validators.user.validate(req.body);
    if (!validation.valid) {
      return {
        status: 400,
        // If validations ends with multiple errors, it will return only first
        // To access them all, look up property validation.errors
        message: validation.popError()
      }
    }
    return createUser(data);
  }
}

Asynchronous validation:

const WV = require('wibe-validator');
const validators = WV.Schemas.create({
  user: require('./path/to/user_schemas.json')
});

class UserResource () {
  static create(req) {
    return validators.user
      .validate(req.body)
      .promise()
      .then(data => createUser(data))
      .catch(error => {
        return {
          status: 400,
          message: error.message
        }
      })
  }
}

Predefined Types

When you create your own schema you can use some predefined types:

• ObjectId - Mongo DB Object Id.
• UUID - Universally unique identifier

Example:

const WV = require('wibe-validator');

module.export = {
  required: ['id'],
  properties: {
    id: WV.Types.ObjectId,
    name: {
	   type: 'string'
    },
};
