Critical Vulnerability in NestJS Devtools: Localhost RCE via Sandbox Escape
A flawed sandbox in @nestjs/devtools-integration lets attackers run code on your machine via CSRF, leading to full Remote Code Execution (RCE).

Advanced tools
Chunk array of objects by their size in JSON
$ yarn add @shelf/array-chunk-by-size
Useful if you want to split large array into smaller, but limited by JSON size.
Each array chunk will be up to specified amount of bytes when stringified into JSON.
import {chunkArray} from '@shelf/array-chunk-by-size';
const bigArray = [{a: 1}, {b: 2}, {c: 3}];
const twoKilobytes = 2 * 1024;
const smallerArrays = chunkArray({input: bigArray, bytesSize: twoKilobytes});
// => [ [ ... ], [ ... ] ] and so on
Alternatively, you might pass a custom size calculation function. For example, to chunk array by LLM tokens size:
import {chunkArray} from '@shelf/array-chunk-by-size';
import {encode} from 'gpt-3-encoder';
const bigArray = ['msg-1', 'msg-2'];
const gpt3MaxTokens = 4000;
const smallerArrays = chunkArray({
input: bigArray,
bytesSize: gpt3MaxTokens,
sizeCalcFunction: item => encode(item).length,
});
