How it works?

This framework will analysis your class and create a validator using ajv for you.

3. Validate object using validator.test({ id: 1, name: 1 })

API

Validate

• function Validate(yourClassType: any): Validator - Create a validator, this validator can be reuse.

• IValidator.test(obj: any): boolean - validate the object, return true if the object match the Class definition.

• IValidator.validate(obj: any): Array - validate the object, return validation errors, if object match, return empty array[]

// Data Models
class ProjectModel {
  @mandatory()
  name: string
}

class DataModel {
  owner: string
  project: ProjectModel
}


// User input
const body = {
                owner: 'Peter',
                project: {
                   name: 1
                }
             }

// Validation Result
const validator = Validate(DataModel)
const results = validator.validate(body)

/*
 results = [
   {
     dataPath: '.project.name',
     params: { type: 'string' },
     message: 'should be string'
   }
 ]
