Dealing with null values in nested arrays in Vue

Coming from a background in Ruby code, I have a question for you. I recently received this API response:

[{:id=>"61b79d02a0f6af001374744e",
  :name=>"Waffle Crewneck",
  :code=>"FW22KS000",
  :result=>{"status"=>"Success", "message"=>"FW22KS000 - Synced"},
  :last_sync_at=>Wed, 18 May 2022 23:51:45.195079000 UTC +00:00},{:id=>"611ea9a7392ab50013cf4713", :name=>"2-Tone Hoodie", :code=>"SS22CH013", :result=>nil, :last_sync_at=>nil},]

I am looking to present this data within a table structure:

<tr v-for="product in fetchedProductSyncStatus" :key="product">

<td class="text-bold">
  {{ product.result.status }}
</td>
<td class="text-bold">
  {{ product.result.message }}
</td>
<td class="text-bold">
  {{ product.last_sync_at }}
</tr>

But when the product.result is nil in the second array element, I encounter an error:

TypeError: Cannot read properties of null (reading 'status')

In Ruby, I would use something like product.result&.message. How can I prevent this error in Vue and display an empty string instead?

Answer №2

In my opinion, the problem lies more in the realm of javascript rather than Vue... You could use the following methods to validate the availability of product.result:

{{product.result ? product.result.status : null}}
, or

{{ product.result && product.result.status }}
