The cjob(Accessing Object) npm package is a utility function that allows you to easily extract/retrieving data from complex JSON structures in Node.js.
npm install cobjcobj(Accessing Object) npm package is a function to easily extract/retrieving data from complex JSON structures by given string path.
$ npm install --save cobj
Uage
Call the cobj function with the and the path in string to the desired value as arguments:`js
const cobj = require('cobj')
const result = cobj(jsonObject, path)
`-
: The JSON object or array from which you want to extract a value.
- path: The path to the desired value within the JSON structure. Use dot notation to navigate through nested objects and arrays. Array indices can be used to access specific elements within arrays.
In this example, the
cobj function will extract the value located at the path 'a.0' within the object.The path specifies that we want to access the element at index 0 within the array a. The extracted value, 1, is then returned and printed to the console.
`js
const cobj = require('cobj')
const mock = {
a: [1, 2]
}
cobj(mock, 'a.0') //1
cobj(mock, 'a.1') //2
`Examples
Example 1: Accessing an Object in a Simple Structure
js
const cobj = require('cobj')
const mock = {
a: [1, 2],
b: 3
}
cobj(mock, 'a.0') //1
cobj(mock, 'a.1') //2
cobj(mock, 'b') //3
`Example 2: Accessing an Array in a Simple Structure
js
const cobj = require('cobj')
const mock = [{ a: 1 }, 2];
cobj(mock, '0.a') //1
cobj(mock, '1') //2
`Example 3: Accessing a Nested Object and Array in a Complex Structure
js
const cobj = require('cobj')
const mock = {
a: {
b: {
c: [
[ {d: 1} ]
]
}
}
}
cobj(mock, 'a.b.c.0.0.d') //1
