Install

$ npm install obj-validate
# OR 
$ yarn add obj-validate

Usage

The module exports a single function that accepts an object and a schema as arguments. The object is validated against the schema, returning errors.

import objValidate from 'obj-validate'
 
const foo = {
  bar: 5,
  baz: 'foo'
}
 
const result = objValidate(foo, {
  bar: {
    required: true,
    type: 'Number',
    pattern: /\d{1}/
  },
  foo: {
    required: true
  },
  baz: {
    type: 'Number'
  }
})
 
console.log(result)
