model-json-js v1.0.6

Model(JSON)js

A JavaScript Model class designed to serialize and transfer structured data within the services/apps you build or across networks. It is paired with Schema(JSON)js to provide structure and validation capabilities to your data model.

Motivations behind the project:

• implement a data serialization solution for structured JSON data
• backed with JSON Schema definition/validation
• leverage modern JS features
• small and lightweight with only one dependency
• universal support for the latest browsers and Node.js
• no code generation

Installing

Install using npm:

npm install --save model-json-js

Examples

Below are a few examples on how to use the Model and Schema classes. For the sake of the following examples, here is a sample Schema we'll reference with all the examples.

// JSON Schema
const TestSchema = {
  title: 'Test',
  $id: 'https://hiveframework.io/api/v1/models/Test',
  type: 'object',
  properties: {
    test: {
      type: 'string'
    },
    another: {
      type: 'string'
    }
  },
  required: ['test']
}
// model FSA
const testData = {
  type: 'Test',
  payload: { test: 'object' }
}

Initialization

• An example Model initialized with raw data and schema.

  const model = await new Model(testData, TestSchema)

• An example Model initialized with a cached JSON Schema references defined.

  const testSchema = await new Schema(TestSchema)
  // ...
  const model = await new Model(testData, testSchema)

• An example immutable Model initialized with raw data and schema.

  const model = await new Model(testData, TestSchema, { immutable: true })

Validation

• Validate the entire Model.

  const isValid = Model.validate(model)

• Validate a single property of the model

  const isValid = Model.validate(model.test, Model.schema(model).test)

Serialization

• Serialize the Model with JSON stringify.

  const json = JSON.stringify(model)

API

• Model
• Schema

Environments

• All modern browsers and Node 10+ without polyfills.

Future

• create contributing guide
• feature requests via issues
