Documentation

Surfing

var Surfing = require('surfing'); var surfing = new Surfing(schema?: Schema, data?: any, options?: Options);

Constructor for a one surfing instance.

travers

surfing.travers();

Run travers by the scheme and data.

errors

surfing.errors: [{ error?: any, schemaPath: [any], dataPath: [any], operatorsPath: [any] }]

Stores error if they throwed as a result of the traversing.

Finding

var Finding = require('surfing/finding'); var finding = new Surfing(schema?: Schema, data?: any, options?: Options);

Targeted traversing of the tree in search of appropriate path.

byOperators

finding.byOperators(...path: [any]) => finding

Find stack level by operators path. Set finding.fail = true if the search failed.

bySchema

finding.bySchema(...path: [any]) => finding

Find stack level by schema path. Set finding.fail = true if the search failed.

byData

finding.byData(...path: [any]) => finding

Find stack level by data path. Set finding.fail = true if the search failed.

Options

Object

Global settings for surfing instance.

dictionary

Object = Surfing.dictionary

In this option you can set a custom dictionary operators.

details

Boolean = true

Defines the detail of error when traversing.

• true by default, all errors will be saved, all paths will be traversed
• false, and operator will stop after the first error, or operator throws one's own error

execute

Boolean = true

It allows you to disable validation on traversing. By default is enabled.

beforeExecution

Function = function(surfing) {}

Handler before execute the logic of the stack level.

afterExecution

Function = function(surfing) {}

Handler after execute the logic of the stack level.

beforeOperation

Function = function(surfing) {}

Handler before call operator of the stack level.

afterOperation

Function = function(surfing) {}

Handler after call operator of the stack level.

It allows to set value under certain conditions.

var data = {
  abc: 123
};
var schema = {

surfing.travers();
surfing.data.abc; // 234

delete

var data = {
  abc: 123
};
var schema = {
  object: {
    props: {
      abc: {
        number: {
          delete: true
        }
      }
    }
  }
}
var surfing = new Surfing(schema, data);
surfing.travers();
surfing.data; // {}

default

It sets the value if it did not exist before.

var data = {};
var schema = {
  object: {

        }
      }
    }
  }
}

surfing.data; // { abc: 123 }

custom

Performs a custom action.

Object syntax

{
  custom: function(surfing) {
    if (surfing.getData() == 123)
      surfing.throw('My custom error');
  }
}

Array syntax

[
  function(surfing) {
    if (surfing.getData() == 123)
      surfing.throw('My custom error');
  }
