get by id from local json http - json

Question

I have fake users.json file and I can http.get to list the array of json.
Since I want to get the particular user by id and haven't stored the data in the database, instead just use the fake json data.
[
{
"id": "cb55524d-1454-4b12-92a8-0437e8e6ede7",
"name": "john",
"age": "25",
"country": "germany"
},
{
"id": "ab55524d-1454-4b12-92a8-0437e8e6ede8",
"name": "tom",
"age": "28",
"country": "canada"
}
]
I can do this stuff if the data is stored in the database, but not sure how to proceed with the fake json data.
Any help is appreciated.
Thanks

Answer 1

If you need the json as raw data, for just fake data, You can simply require it and use it as object..
const JsonObj = require('path/to/file.json')
console.log(JsonObj[0].id) // <-- cb55524d-1454-4b12-92a8-0437e8e6ede7
Plus, if you need more dynamic solution, there is a good JSON-server you can easily use for testing and so: check this git repo

var _ = require('underscore');
var dummyJson = [
{
"id": "cb55524d-1454-4b12-92a8-0437e8e6ede7",
"name": "john",
"age": "25",
"country": "germany"
},
{
"id": "ab55524d-1454-4b12-92a8-0437e8e6ede8",
"name": "tom",
"age": "28",
"country": "canada"
}
]
var requiredID = "cb55524d-1454-4b12-92a8-0437e8e6ede7";
var reuiredObject = _.find(dummyJson, function (d) {
return d.id === requiredID;
})

Get JSON object using JSON.parse('users.json') and store it in a variable users.
Loop through array of users using for .. in and using if condition on id update the object if required.
Stringify the updated users object using JSON.stringify(users); and write this string to users.json file using fs.write() module in NodeJS so you will have updated objects in your json file.
