Fork, change and PR

Help me forking and improving the code, I promise that your pull request will be merged soon! :)

Installation

It's very easy!

npm install validator-schemas --save

And booom! You may have it in your node-modules. You can also clone this repo using:

git clone https://github.com/victorlucss/validator-schemas.git

Usage

First of all you'll need to instantiate the validator

const validator = require('validator-schemas')

After that you will need to build your own Schema.

const schema = {
    _name: "MyOwnSchema", 

    firstName: {
        type: "string",
        required: true
    }
}

After that you can run the validator in some object (or json parsed to object) and remember to use try...catch to catch every exception of validation!

const data = {
    firstName: "Victor"
}

try {
    validator.validateSchemas(data, schema)
}catch(ex){
    console.error(ex)
}

Supported types

• string
• integer
• float
• boolean
• timestamp
• object - requires of field, that recieves a schema
• map - requires mapOf field, that recieves a schema
• list - you can set the type by passing listOf field, that recieve another type (can be some of the listed)

Non-listed entries

If you have some json with not maped keys, like the following...

{
    "48": 150,
    "52": 32,
    "product": "Clothes"
}

Where the 48, 52 keys can be some other number, you'll need to validate that as non-listed entry. To do this you need to create a schema with _otr (abbreviation of "others"):

const schema = {
    product: {
        type: "string"
    },

    _otr: {
        key: "[0-9]+",
        value: "integer" //You can use any of supported types.
    }
}

Now, your validation will cover every fields.
