ODataClient

How to use @odata/client

Start with a simple query, following code start a GET http request, and asks the server to respond to all customers which phone number equals 030-0074321

import { OData } from "@odata/client"
// import "@odata/client/lib/polyfill" // server side polyfill

// odata.org sample odata service
const serviceEndpoint = "https://services.odata.org/V2/Northwind/Northwind.svc/"
const client = OData.New({ serviceEndpoint })

const runner = async () => {
  
  // Query by filter
  //
  // GET /Customers?$format=json&$filter=Phone eq '030-0074321'
  const filter = client.newFilter().property("Phone").eq("030-0074321");

  // just an example, suggest to use the EntitySet API
  const result = await client.newRequest({ // ODataRequest object
    collection: "Customers", // entity set
    params: client.newParam().filter(filter) // odata param
  })

}

// OData V4 client
const client = OData.New4({ serviceEndpoint: "https://odata-v4-demo-001.herokuapp.com/odata/" })
