Retrieving reduced or corresponding items from a JSON document

My JSON data is structured as follows:

[
    {
        "id" : "1",
        "type" : "hardware"
    },
    {
        "id" : "2",
        "type" : "software"
    }
]

When I execute the following code:

$http({
        method: 'get',
        url: '/tools.json'
    }).success(function(data, status, headers, config) {
        ///whatever
    })

I retrieve these two objects for rendering using ng-repeat, which works fine.

Now, I am looking to implement filters in my application to display only "Hardware" or "Software" items. What is the most efficient way to accomplish this? Can I directly retrieve Hardware items from the JSON itself (querying JSON and fetching matching objects)? If so, how can I achieve this? Do I need to make changes in the code to implement this functionality, or should I utilize Angular filters to render Hardware type objects after retrieving the entire JSON?

As an individual with limited experience in Angular development, I would appreciate any alternative approaches to achieve my goal.

Thank you in advance.

Answer №1

The decision is entirely up to you.

It would be best if your backend could provide the filtered JSON results.

If you're looking for immediate feedback, consider utilizing Angularjs filters to handle the filtering directly on the data retrieved from the server. This approach also allows for full-text search capability, which is quite impressive.

Answer №2

If you're looking to specifically sort through JSON data, one approach is to utilize the reduce method in JavaScript like this:

var hardwareItems = jsonData.reduce(function(filteredData, currentItem) {
    if(currentItem.type === 'hardware') {
        filteredData.push(currentItem);
    }

    return filteredData;
}, []);

You can experiment with a live example on this JSFiddle link.

Answer №3

If you prefer to handle this type of filtering on the backend due to the data type, that would be ideal. However, if for any reason you need to perform this task in the browser, you can utilize a simple for loop to filter out objects with the type of hardware. A more efficient solution would involve using the underscore library. By incorporating the underscore source file into your project, you can leverage the _.filter function to easily target and filter the objects you require.
