find the size of a json file in typescript

To find the size of a JSON file in TypeScript, you can use the fs module provided by Node.js. First, you need to import the fs module as shown below:

index.ts
import * as fs from 'fs';
26 chars
2 lines

Then you can use the statSync method of the fs module to get the file stats, including the size of the file. Here is an example code snippet that retrieves the size of a JSON file:

index.ts
const fileName: string = 'data.json';
const stats: fs.Stats = fs.statSync(fileName);
const fileSizeInBytes: number = stats.size;
console.log(`File size: ${fileSizeInBytes} bytes`);
181 chars
5 lines

In the code above, we first define the file name as a string (data.json in this example). Then we use the statSync method of the fs module to retrieve the file stats, including the size of the file. Finally, we print out the size of the file to the console.

Note that the file size is returned in bytes. If you want to convert it to another unit of measurement (such as kilobytes or megabytes), you can do so by dividing the file size by the appropriate conversion factor.
