# json-api-normalizer
Utility to normalize JSON:API data with ease
[](https://badge.fury.io/js/%40lysyi3m%2Fjson-api-normalizer)
## Description
json-api-normalizer helps to processing [JSON:API](https://jsonapi.org/) data into more developer-friendly form for further usage. It fully supports [latest JSON:API specification](https://jsonapi.org/format/) including one-to-one & one-to-many relationships, so you don't need to manually format each response to work with regular resource collections. It's main feature is correct exctracting so called ["sparse fieldsets"](https://jsonapi.org/format/#fetching-sparse-fieldsets) and nesting them under corresponding resource.
## Installation
```sh
$ npm install @lysyi3m/json-api-normalizer
```
or using [Yarn](https://yarnpkg.com/):
```sh
$ yarn add @lysyi3m/json-api-normalizer
```
## Usage
```js
import normalizer from '@lysyi3m/json-api-normalizer';
// make a request tou your API endpoint and get response
const result = normalizer(response.data);
console.log(result.data) // data is normalized resources with exctracted & nested relationships
console.log(result.meta) // meta object
console.log(result.links) // links object
```
## Examples
### Basic
Assuming endpoint `/articles?include=author`, your response data would be like this:
```json
{
"data": [{
"type": "articles",
"id": "1",
"attributes": {
"title": "JSON:API paints my bikeshed!",
"body": "The shortest article. Ever.",
"created": "2015-05-22T14:56:29.000Z",
"updated": "2015-05-22T14:56:28.000Z"
},
"relationships": {
"author": {
"data": {"id": "42", "type": "people"}
}
}
}],
"included": [
{
"type": "people",
"id": "42",
"attributes": {
"name": "John",
"age": 80,
"gender": "male"
}
}
]
}
```
And after normalization:
```json
{
"data": [
{
"id": "1",
"title": "JSON:API paints my bikeshed!",
"body": "The shortest article. Ever.",
"created": "2015-05-22T14:56:29.000Z",
"updated": "2015-05-22T14:56:28.000Z",
"author": {
"id": "42",
"name": "John",
"age": "80",
"gender": "male"
}
}
]
}
```
### Complex relationships
In case one-to-one, one-to-many or nested relationships (i.e., when relationship resource has its own relationships), json-api-normalizer will proccess them at once, using matching by resource id & type altogether.
Assuming endpoint `/articles?include=author,comments`, your response data would be like this:
```json
{
"data": [{
"type": "articles",
"id": "1",
"attributes": {
"title": "JSON:API paints my bikeshed!"
},
"links": {
"self": "http://example.com/articles/1"
},
"relationships": {
"author": {
"links": {
"self": "http://example.com/articles/1/relationships/author",
"related": "http://example.com/articles/1/author"
},
"data": { "type": "people", "id": "9" }
},
"comments": {
"links": {
"self": "http://example.com/articles/1/relationships/comments",
"related": "http://example.com/articles/1/comments"
},
"data": [
{ "type": "comments", "id": "5" },
{ "type": "comments", "id": "12" }
]
}
}
}],
"included": [{
"type": "people",
"id": "9",
"attributes": {
"first-name": "Dan",
"last-name": "Gebhardt",
"twitter": "dgeb"
},
"links": {
"self": "http://example.com/people/9"
}
}, {
"type": "comments",
"id": "5",
"attributes": {
"body": "First!"
},
"relationships": {
"author": {
"data": { "type": "people", "id": "2" }
}
},
"links": {
"self": "http://example.com/comments/5"
}
}, {
"type": "comments",
"id": "12",
"attributes": {
"body": "I like XML better"
},
"relationships": {
"author": {
"data": { "type": "people", "id": "9" }
}
},
"links": {
"self": "http://example.com/comments/12"
}
}]
}
```
And after normalization:
```json
{
"data":[
{
"id":"1",
"links":{
"self":"http://example.com/articles/1"
},
"title":"JSON:API paints my bikeshed!",
"author":{
"id":"9",
"links":{
"self":"http://example.com/people/9"
},
"first-name":"Dan",
"last-name":"Gebhardt",
"twitter":"dgeb"
},
"comments":[
{
"id":"5",
"links":{
"self":"http://example.com/comments/5"
},
"body":"First!",
},
{
"id":"12",
"links":{
"self":"http://example.com/comments/12"
},
"body":"I like XML better",
"author":{
"id":"9",
"links":{
"self":"http://example.com/people/9"
},
"first-name":"Dan",
"last-name":"Gebhardt",
"twitter":"dgeb"
}
}
]
}
],
}
```
## Available options
### `Camelize`
By default json-api-normalizer does not transform data keys. If `camelize` option is set to `true` all keys will be converted to [camelCase](https://wikipedia.org/wiki/Camel_case).
