jsonarrayfs/dist/index.d.mts

Specialized Node.js library for memory-efficient operations on JSON arrays. Stream individual elements from large JSON arrays (files, network responses etc.) and append elements to array files without loading the entire array into memory. Perfect for proc

import { Transform, TransformCallback } from 'node:stream';

declare class JsonArrayStream<T> extends Transform {
    /**
     * Special value to distinguish between JSON null and stream EOF.
     * Use this to check if a streamed element is null:
     *
     * ```typescript
     * if (element === JsonArrayStream.NULL) {
     *   console.log('Found null in JSON');
     * }
     * ```
     */
