Obtain the JSON object by provided criteria

In the given JSON data, how can I access an object based on the provided applicationName?

{
    "apps": [
        {
            "applicationName": "myTestApp",
            "keys": [
                {
                    "key": "app-key",
                    "value": "ZDM0"
                },
                {
                    "key": "env-key",
                    "value": "YTE1Mm"
                }
            ]
        },
        {
            "applicationName": "hello",
            "keys": [
                {
                    "key": "app-key",
                    "value": "ZjIwZT"
                },
                {
                    "key": "env-key",
                    "value": "MDExMTc5N2"
                }
            ]
        }
    ]
}

If my input is 'myTestApp', I wish to retrieve the corresponding object:

{
    "applicationName": "myTestApp",
    "keys": [
        {
            "key": "app-key",
            "value": "ZDM0"
        },
        {
            "key": "env-key",
            "value": "YTE1Mm"
        }
    ]
}

Answer №1

Here's a useful code snippet to find a specific app from a list of apps called `data`:

const targetApp = data.apps.find(app => app.applicationName === "myTestApp");

if (targetApp) {
    console.log(targetApp); // The desired app is found!
} else {
    console.log("App not found."); // App with the specified name doesn't exist.
}

Answer №2

let myJsonData; // insert your unique json data in this variable

let applicationsArray = myJsonData.applications;

for (const index in applicationsArray) {
   if(applicationsArray[index].appName === "uniqueTestApp") {
      const targetObject = applicationsArray[index];
      break;
   }
}

The targetObject is the desired object.

Answer №3

Iterating through a JSON array and checking the values of the applicationName is recommended. To see an example, visit this fiddle:

http://jsfiddle.net/123abc456/

let jsonData = yourJSONdata;
for(let key in jsonData.apps){
if("hello" === jsonData.apps[key].applicationName)
    console.log(key);
}

If you have a large JSON file, utilizing an external JavaScript library like Reflective () can greatly enhance searching capabilities.
