Package Exports

@hasura-ws/model

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@hasura-ws/model) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

`@hasura-ws/model`

A model gives you a basic CRUD + subscribe for your data models

Initialize a model

import { initClient } from '@hasura-ws/browser'

const client = initClient({
  address: 'ws://localhost:8080/v1alpha1/graphql',
  token: 'eyJhbGciOiJIUzI...w5c',
})

// if you want react hooks, use initPrepareWithHooks from @hasura-ws/hooks
const prepare = initPrepare(client) 
const initModel = buildModel(prepare)

// initModel takes 2 arguments: the table name and the field names
const userModel = initModel('user')(`
  email
  firstname
  lastname
`)

`model.add`

// adding a single element
const id = await userModel.add({
  email: 'jean@email.com'

// or an array of elements
const ids = await userModel.add([
  {
