yarn add @mykulyak/json-api

Quick start

Consider a simple blog API designed according to JSON:API spec. It returns article, author and comment resources:

author may have zero or more articles
article has one author
article may have zero or more comments

The API request for creating a new article might look somethling like this:

{
  "data": {
    "type": "create-article",
    "attributes": {
      "title": "Why should we use JSON:API ?",
      "content": "..."
    },
    "relationships": {
      "author": {
        "type": "author",
        "id": "123"
      }
    }
  },
  "jsonapi": { "version": "1.0" }
}

whereas in the application we would likely have the data look like:

{
  "authorId": 123,
  "title": "Why should we use JSON:API ?",
  "content": "..."
}

Using json-api, one can build the request from form data in the following way:

import { registry } from '@mykulyak/json-api';

const author = registry.define({
  type: 'author',
});

const createArticle = registry.define({
  type: 'create-article',
  attributes: ['title', 'content'],
  relationships: {
    author: {
      attribute: 'authorId',
      resource: author,
    },
  },
});

const request = createArticle.resource({
  authorId: 123,
  title: "Why should we use JSON:API ?",
  content: "..."
});
