JsonAPI Adapter based on js-data-http for js-data
This adapter just add a light serialize and deserialize layer over DSHttpAdapter.
| package | requirement |
| ------------ | ------------- |
| js-data | >= 3.0.0 |
| js-data-http | >= 3.0.0 |
By design it is not compatible with JS-Data v2, for a full integration on v2, you should use: js-data-jsonapi.
First you need to install everything needed :
npm install --save js-data js-data-http js-data-jsonapi js-data-jsonapi-light
Load js-data-jsonapi-light.js last.
``jsvar DataStore = JSDate.DataStore
import { DataStore } from 'js-data'
// or
import { JsonApiAdapter } from 'js-data-jsonapi-light'
// or var JsonApiAdapter = JSDataJsonApiLight.JsonApiAdapter
// Initialize our Store
const store = new DataStore();
// Initialize our Adapter
const jsonApiAdapter = new JsonApiAdapter({
// Same options as DSHttpAdapter
// However, you should use before/after deserialize/serialize instead of serialize/deserialize
});
// Register the Adapter as the default one in the store
store.registerAdapter('jsonApi', jsonApiAdapter, { default: true })
`
* You can find examples of Mapper Definitions in test/resources.
* Fake JsonAPI responses corresponding to those mapper can be found in test/api
* Bootstrap of JSData + JsonAPI could be found in test/ds
* Exemple of use could be found in test/unit
JSData works with mappers which define the communication part and the way your resources are linked together
`
const UserMapper = window.store.defineMapper('User',{
endpoint: 'users', // optional, it will default to
relations: {
hasOne: {
'UserProfile': {
localField: 'profile',
foreignKey: 'userId'
}
},
hasMany: {
'Article': {
localField: 'articles',
foreignKey: 'authorId'
}
},
belongsTo: {
'UserGroup': {
localField: 'group',
localKey: 'groupId'
}
}
}
})
`
UserMapper.findAll({ include: 'profile' }).then((records) => {
console.log(records);
})
Once some records has been loaded they are also cached in the DataStore, you can access them synchronously with :
`
records = store.getAll('User')
Sometime you want to be able to do some custom additional serialization / deserialization.
#### By using the adapter
`js`
const jsonApiAdapter = new JsonApiAdapter({
beforeDeserialize: function(mapper, data, opts) { return data; }
afterDeserialize: function(mapper, data, opts) { return data; }
beforeSerialize: function(mapper, data, opts) { return data; }
afterSerialize: function(mapper, data, opts) { return data; }
});
#### By using the mapper
`js`
const UserMapper = store.defineMapper('User', {
beforeDeserialize: function(mapper, data, opts) { return data; }
afterDeserialize: function(mapper, data, opts) { return data; }
beforeSerialize: function(mapper, data, opts) { return data; }
afterSerialize: function(mapper, data, opts) { return data; }
});
#### When doing requests
`js
store.findAll('User', {}, {
beforeDeserialize: function(mapper, data, opts) { return data; }
afterDeserialize: function(mapper, data, opts) { return data; }
});
store.update('User', {}, {
beforeSerialize: function(mapper, data, opts) { return data; }
afterSerialize: function(mapper, data, opts) { return data; }
});
`
#### beforeDeserialize, afterDeserialize, beforeSerialize, afterSerialize
Deserialization and serialization hooks, see above.
#### raw: boolean
Send back raw response
Eg. To retrieve JSONApi Meta :
`js`
store.findAll('User', {}, {
raw: true
}).then((response) => {
console.log(response.data); // Return the Records
console.log(response.meta); // Return the JSONApi Metas
console.log(response.rawData); // Return the full response (should be discarded as soon as possible to save memory)
})
* Compatible with: all
#### forceReplace: boolean(false)
On update, force all fields to be sent even if they haven't been changed.
It will switch from default PATCH http verb to PUT.
If some properties are passed to the update, only those will be sent. Those who has not changed compared to the record original properties will not be sent.
Be careful, because it means, once the update made, the server will return saved datas, and it will erased possible properties that were changed on the record but not given to the update. Nothing wrong with that, it's the correct behavior, but you should know about this logic.
* Compatible with: update, save
#### forceRelationshipsInAttributes: boolean(false)
On update, force all relationships data to be sent using attributes structure instead of default relationships within the resource object.
Note it is not JsonAPI compliant, it is a convenient option to support some specific backends.
* See #23
* Compatible with: update, save
#### beforeDeserialize, afterDeserialize, beforeSerialize, afterSerialize`
Deserialization and serialization hooks, see above.
* Deserialization, supporting hasMany, hasOne, belongsTo relationships
* Meta handling
* Serialization
* Custom hooks
* By default update PATCH changes instead of PUT the record
* Error handling (need intensive testing)
* ManyToMany
