ValidatorSchemas is a simple way to validate objects or jsons in Node.js.

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

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

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)
}

• 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)

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.
