Utilizing JSON API filtering within a Next.js application

Recently delving into the world of coding, I've embarked on a personal project that has presented me with a bit of a challenge regarding API filtering. My goal is to render data only if it contains a specific word, like "known_for_department==Directing." How can I achieve this in ReactJS? Any assistance would be greatly appreciated.

{
            "adult": false,
            "gender": 2,
            "id": 1787802,
            "known_for_department": "Directing",
            "name": "Brian Avery Galligan",
            "original_name": "Brian Avery Galligan",
            "popularity": 0.63,
            "profile_path": null,
            "credit_id": "5fd051d968929c003bc48070",
            "department": "Directing",
            "job": "Second Unit First Assistant Director"
        },
        {
            "adult": false,
            "gender": 1,
            "id": 1774412,
            "known_for_department": "Production",
            "name": "Rachel O'Connor",
            "original_name": "Rachel O'Connor",
            "popularity": 0.6,
            "profile_path": null,
            "credit_id": "6124530a0f2fbd004815b6cb",
            "department": "Production",
            "job": "Executive Producer"
        },

This is the JSON data from the API that requires filtering based on the condition known_for_department==Directing. If true, all items meeting this criteria should be rendered on the page. Your guidance will be highly valued. Thank you!

Answer №1

There are two choices available:

A. Construct your API requests using specific keywords (recommended)

B. Sort through your data on the client-side (not ideal). This approach may result in slower code execution.

let inputData = [
        {
            "adult": false,
            "gender": 2,
            "id": 1787802,
            "known_for_department": "Directing",
            "name": "Brian Avery Galligan",
            "original_name": "Brian Avery Galligan",
            "popularity": 0.63,
            "profile_path": null,
            "credit_id": "5fd051d968929c003bc48070",
            "department": "Directing",
            "job": "Second Unit First Assistant Director"
        },
        {
            "adult": false,
            "gender": 1,
            "id": 1774412,
            "known_for_department": "Production",
            "name": "Rachel O'Connor",
            "original_name": "Rachel O'Connor",
            "popularity": 0.6,
            "profile_path": null,
            "credit_id": "6124530a0f2fbd004815b6cb",
            "department": "Production",
            "job": "Executive Producer"
        },
]

let outputData = []

for (const element of inputData){
    if (element["department"] === "Directing"){
        outputData.push(element)
    }    
}
console.log(outputData)

Answer №2

To incorporate something similar in your return statement, you can do the following:

{if (known_for_department === directing) && <something/> }

The content to the right of the && operator will only be executed (in this case: displayed) if the left part is true.

For example:

return (

{api_data.known_for_department === api_data.directing && ({api_data.map((element) => <p>{element}</p>)}
)

This code will generate paragraphs for all properties within your api_data.

If you need to display something different when the condition is false, you can use a ternary operator like so:

{known_for_department === directing ? <something/> : <something_else/> }

If you want the return statement to only run if the condition is true, you can write:

if (known_for_department === directing) {
return (something...)
}
