Admin Api Schema

The package serves as a single source of truth when validating requests coming into Ghost's Admin API endpoints. It uses JSON Schema definitions under the hood to describe expected format of validated data.

Install

npm install @tryghost/admin-api-schema --save

or

yarn add @tryghost/admin-api-schema

Usage

const jsonSchema = require('@tryghost/admin-api-schema');

// check available schemas
jsonSchema.list()
/*
> [
  'images-upload', 'labels-add',
  'labels-edit',   'members-add',
  'members-edit',  'members-upload',
  'pages-add',     'pages-edit',
  'campaigns-add',     'campaigns-edit',
  'products-add',     'products-edit',
  'posts-add',     'posts-edit',
  'tags-add',      'tags-edit',
  'webhooks-add',  'webhooks-edit'
]
*/

// get schema definition
jsonSchema.get('tags-edit');
/*
> {
  '$schema': 'http://json-schema.org/draft-07/schema#',
  '$id': 'tags.edit.canary',
  title: 'tags.edit',
  description: 'Schema for tags.edit',
  type: 'object',
  additionalProperties: false,
  properties: {
    tags: { type: 'array', minItems: 1, maxItems: 1, items: [Object] }
  },
  required: [ 'tags' ]
}
*/

// validate data
const data = {
    posts: [{
        title: 'valid'
    }]
};

try {
    await apiSchema.validate({data, schema: 'posts-add'});
} catch (err) {
    console.log('validateion error:', err);
}

When used from Ghost core in validation layer:

const jsonSchema = require('@tryghost/admin-api-schema');
const validate = async (apiConfig, frame) => await jsonSchema.validate({
    data: frame.data,
    schema: `${apiConfig.docName}-${apiConfig.method}`,
    version: 'canary'
});
