Trying to find a library that can validate input in a specific format, such as:
{ points: array of { x: positive and less than 20, y: positive and less than 15 } }
Ideally, it should work on both server and client sides and either return a boolean or throw an exception.
What I'm specifically looking for is not string or form validation, but rather a way to quickly determine if the JSON data sent by a client is safe for processing without having to do multiple checks manually.
If you're looking for a reliable tool to structure and validate data, consider giving Skematic a try.
Skematic is a versatile data structure and rule validation engine that provides a robust schema for JavaScript objects.
It allows you to create data models, format your data accordingly, and ensure its validity based on predefined models. Whether it's in the browser (using the global Skematic) or Node/io.js, Skematic can be easily utilized.
To address your specific needs, a simple code snippet like the following should suffice:
// -- Define a straightforward data structure
var YourData = {
points: {
type:'array',
default: [],
schema: {
x: { type: 'number', required: true, rules: { min:0, max:20 } },
y: { type: 'number', required: true, rules: { min:0, max:15 } }
}
}
};
// -- Validate an object
Skematic.validate( YourData, {points:[ {x:-1,y:10} ]} );
// {valid:false,
// errors:{
// points: {0:{x:['Failed: min']}}
// }}
Decided to write it myself instead.
