easy-schemas
A Node.js Schema package to validate items easily.
Installing
npm install --save easy-schemas
How to use?
First you need to import this package:
// ES5
const Schema = require('easy-schemas');
// ES6
import Schema from 'easy-schemas';
Then you need to create an schema:
let Point = { x: Number, y: Number };
// it could also be:
let Point = { x: { type: Number }, y: { type: Number } };
// or:
let Point = { x: { type: 'number' }, y: 'number' };
After that you just validate it:
let p = { x: 2, y: 3 };
let validation = Point.validate(p);
if (!validation.valid) { // Invalid validation
console.log(validation.errors) // Simple list of errors
}
Schema type options:
- type: Required. It is the wanted type (an Schema, a class or an String to evaluate)
- min: Optional. Allows to check the length of arrays and strings, or the value if it's a number or date.
- max: Optional. Works just the same way as min, but for maximun value.
- required: Optional. By default, all fields are nulleable (undefined fields are still invalid), use
required: true
to avoid that. - pattern: Optional. Used to check if a String matches this pattern (it must be a RegExp).
- validator: Optional. A function as the value as argument, if custom or complex validation is needed.
