Understanding the Docly Functions
Docly has two primary functions that facilitate the reading and writing of JSON files:
| Function | Description |
|---|---|
| docly.getJson(filename) | This function takes a filename as a parameter and returns a JavaScript object representing the content of the JSON file. This object can then be manipulated as required. |

Appending Data to a JSON File in Docly
Now, let's dive into a practical example where we append new data to a JSON file:
> 1. Retrieve Existing Data
Firstly, let's retrieve the data in your JSON file. We will call the docly.getJson(filename) function, passing the name of your JSON file as an argument:
let data = docly.getJson('myFile.json');> 2. Append New Data
Having loaded the existing data, it's time to append new information. Given the flexibility of JavaScript objects, the method you'll use to append data depends on whether your JSON data is structured as an array or an object.
If your data is an array, you can simply use the push() method:
let newData = {key: 'value'}; // Your new data here
data.push(newData);On the other hand, if your data is an object, you can add a new key-value pair:
let newData = {key: 'value'}; // Your new data here
data.newKey = newData;
> Save the Updated Data
With your data successfully appended, it's time to save the updated JavaScript object back to the JSON file. To do this, we will call the docly.saveJson(filename, object) function:
docly.saveJson('myFile.json', data);And there you have it! You've successfully appended data to a JSON file in Docly using JavaScript.
Conclusion
