reddit 주석 데이터 구조를 병합하는 방법은 무엇입니까?

Question

reddit 주석 데이터 구조를 평평하게하기 위해 normalise api를 사용하려고합니다.

예를 들어, 아래 전화 :

https://www.reddit.com/r/reactjs/comments/506gca/what_backend_and_db_are_you_using_with_react/.json 

당신에게 중첩 된 구조를 제공한다. 다음과 같습니다

정확하게, data.children 배열은 다시 등 replies을 가지고 할 수있는, 다시 data을 가질 수 replies 키를 가지고있다.

이 재귀 구조를 어떻게 평평하게하는지보고 싶습니다. replies을 업데이트하는 동안, 감속기에서 구조를 올바르게 탐색하기가 어려워졌습니다. (그것을 표시하는 동안, 그것으로 쉽게 탐색 할 수 있습니다)

어떤 도움이 될 것입니다!

저는 reddit API에 익숙하지 않지만이 점에 대해 어떻게 생각하십니까? 귀하의 예제가 x에 저장되어있는 경우

// this should be handled more explicitly 
function normalize(input) { 
    if(input.data) return normalize(input.data); 
    if(input.children) return normalize(input.children); 
    return input; 
} 

function build(input) { 
    const result = {}; 
    if(input.replies) { 
    input.replies = normalize(input.replies).map((data) => { 
     const reply = normalize(data); 
     Object.assign(result, build(reply)); 
     return reply.id; 
    }); 
    } 
    result[ input.id ] = input; 
    return result; 
} 

, build(normalize(x[0])); 당신을 제공해야합니다 :
