I'm trying to work with a json file but I can't figure out how to read just a specific object from a json file.
My current code looks like this:
try {
const data = fs.readFileSync("addresses.json", "utf8");
console.log(data);
} catch (err) {
console.error(err);
}
This works fine. However when I try to get some object from the file like this:
console.log(data.address)
It doesn't work because it is a string.
So my question is how can I read just a single object from the json file.
Thanks a lot!
Try:
const parsedData = JSON.parse(data)
const address = parsedData.address
You need to use JSON.parse(), as right now, you are trying to access a property off of a string. However, the method will change it to an object.
// Dummy JSON data
const data = `{ "address": "Stack Overflow" }`;
const json = JSON.parse(data);
console.log(json.address);This will make it possible to access the properties off of the object.
you must convert the data into json like so:
JSON.parse(data)
In your example :
try {
const data = fs.readFileSync("addresses.json", "utf8");
console.log(JSON.parse(data).address);
} catch (err) {
console.error(err);
}
I hope I answered your question. Feel free to comment if I misunderstood you or you have some questions ;)
