Create validation injector

[sradevski]

Libraries that can be used internally for validation:

• https://github.com/chriso/validator.js for all string-based validations.
• https://github.com/ianstormtaylor/superstruct
• https://github.com/imbrn/v8n

The validator can accept an array of "types" like unique, id, or custom validation functions.

General flow:

• Get the hash value of each validation function.toString(), and store it in an object such as

const validators = {
[hashval]: () => null,
}

• Iterate over each object in each definition
• Get the validation function
• If it is string, replace it with the hashval for that pre-defined function
• If it is a function get the hash value of that function.toString(), add it to the rest of validators and replace it with the hash value.
• At the end, you can potentially remove the unused pre-defined functions, but it is not necessary for a start.
• Once all validators are generated, output them to a file exported as an object as the validators object above
• In a separate file, create the validation executor which will be the connection between the validator functions and the hash value for each field in each definition.
