Escape colon in Reactive Search field name

Question

I am testing a very basic reactive search implementation.

My code is as below: import React, { Component } from 'react'; import { ReactiveBase, DataSearch, ResultCard } from '@appbaseio/reactivesearch'; import logo from './logo.svg'; import './App.css';

class App extends Component {
  render() {
    return (
      <div className="App">
        <header className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h1 className="App-title">Welcome to React</h1>
        </header>

        <ReactiveBase
            app="indexName"
            url="https://someurl.amazonaws.com"
          >

          <DataSearch
            componentId="SearchSensor"
            dataField={ "field_product:title" }
            autoSuggest={true}
          />    

          <ResultCard
             componentId="results"
             dataField="field_product"
             react={{
               "and": ["SearchSensor"]
             }}
             onData={(res)=>({
               "image": res.image,
               "title": res.field_product:title,
               "description":   res.description
             })}
           />

          </ReactiveBase>
      </div>
    );
  }

}

export default App;

My fields in index look somewhat as below:

{
  "_index": "kirana11",
  "_type": "product_autocomplete",
  "_id": "66641",
  "_version": 1,
  "_score": 1,
  "_source": {
    "id": 66641,
    "description": "Some Nestle Product ",
    "field_product:title": "Nestle Product",    
    "field_product:commerce_price:amount": 83
}

In the above example, when I call fields like res.image it works flawlessly. However, fields like field_product:title & field_product:commerce_price:amount returns an error as below:

Syntax error: Unexpected token, expected, (34:41)

What is the right way to access fields with a colon in it? Is there a way to escape it?

Answer 1

Wrap it around quotes and use bracket instead of dot notation to access the property:

res['field_product:title']

This is also how you would access a property using a variable:

const key = 'field_product:title';
res[key]

It might be better to change your json structure though:

fieldProduct: {
  title: '',
  commercePrice: ...
}
