``There are problems with parsing JSON data due to the error message indicating the presence of unexpected

I am encountering an issue with displaying values from objects stored as string[] in appwriteDB. When trying to use *ngFor to iterate through the data, I faced difficulties. Despite attempting to convert the orderItems using JSON.parse(), the process failed due to unexpected white space detection.

    [
      {
        "orderStatus": "New",
        "orderPayment": "Paid",
        "orderItems": [
          "{\"productName\":\"Nokia Windows mobile\",\"productPrice\":299,\"productDetails\":\"Nokia windows 10 mobile\",\"productAvailable\":true,\"qty\":1,\"$id\":\"65f21c5cdd3449f30f68\",\"$createdAt\":\"2024-03-13T21:36:28.906+00:00\",\"$updatedAt\":\"2024-03-13T21:36:28.906+00:00\",\"$permissions\":[],\"$databaseId\":\"smartCartDB\",\"$collectionId\":\"Products\"}"
        ],
        "$id": "65f6fcc4e65c46fc6e97",
        "$createdAt": "2024-03-17T14:23:00.944+00:00",
        "$updatedAt": "2024-03-17T14:23:00.944+00:00",
        "$permissions": [],
        "products": [],
        "$databaseId": "smartCartDB",
        "$collectionId": "Orders"
      }, ...

Efforts to resolve this through JSON.parse have proven unsuccessful. What would be the most effective strategy for converting the specific orderItems object?

method:1

res.documents.map((el:any) => {return JSON.parse(el.orderItems)} ));

method:2

res.documents.map((el:any) => {
    return el.orderItems.map((el2:any) => {return JSON.parse(el2)})
})

I seek guidance on the optimal approach to address my current predicament.

Answer №1

The issue stems from attempting to JSON.parse(el.orderItems)}, where orderItems is a collection of strings. Instead, it's necessary to iterate through the orderItems and stringify each individual string. Here's how you can accomplish this:

const result = data.map((order) => {
    return order.orderItems.map((item) => {
        return JSON.parse(item)
    })
})

To correctly parse the array of objects in orderItems, you can simply use JSON.parse(data). This is how the code should look:

    const parsedData = data.map(item => {
      return {
        ...item,
        orderItems: [item.orderItems.map(order => JSON.parse(order))]
      }
    })
