AJV Utils

A utility package for ajv which provides additional keywords for usage within your schema.

This package was created with guidance from ajv-keywords.

Keywords

Keywords for objects

renameKeys

This keyword renames properties within an object to the desired name. It's primary use is to validate a payload received from an upstream system and transform the object property names as required in the local system.

The renameKeys property in the schema is represented as an Object where the key is the origin property name and the value is the desired property name.

const schema = {
  type: 'object',
  properties: {
    id: {
      type: 'number'
    },
    name: {
      type: 'string'
    }
  },
  renameKeys: {
    name: 'firstName'
  }
};

const data = {
    id: 123,
    name: 'John'
};

ajv.compile(schema)(data);

// Result object:
// data = {
//     id: 123,
//     firstName: 'John'
// }
