I am trying to check if a a subreddit contains ANY posts that match the users search criteria. Ive tried a few methods but non of them seem to be able to only rely if the results are empty or not.

fetch(`https://www.reddit.com/r/${redsearch}/search.json?q=${redsearch}&restrict_sr=on&sort=relevance&t=all&limit=100`)
    .then(function (response) {
        return response.json()
    }

this is currently what i found to be the only thing that comes close to searching and returning the results but I am unable to understand how I can filter out the JSON so I can check weather the search was successful or if the search result was empty

can help or ideas will be greatly appreciated

It looks to me like the response object has a data property and inside that a children property. If the children property is empty that would mean no results found for that search. You can compare these two responses that I got.

{
  "kind": "Listing",
  "data": {
    "modhash": "",
    "dist": 0,
    "facets": {},
    "after": null,
    "geo_filter": "",
    "children": [],
    "before": null
  }
}

and

{
  "kind": "Listing",
  "data": {
    "modhash": "",
    "dist": 1,
    "facets": {},
    "after": "t3_vwcqap",
    "geo_filter": "",
    "children": [
      {
        /*removed data to make it clearer*/
      }
    ],
    "before": null
  }
}

CodePudding user response：

as @jaacima mentioned you can check it within the children property to see if any results were found

    fetch(`https://www.reddit.com/r/crackwatch/search.json?q=${redsearch}&restrict_sr=on&sort=relevance&t=all&limit=100`)
    .then(function (response) {
        return response.json()
    })
    .then(function (data) {
        if (data.data.children.length === 0) {
            console.log("No results found")
        }
        else
        {
            console.log("Results found")
        }
    })

heres the code snippet for anyone who stumbles across this problem
