Quick start

import { GoodsExporter, Product, Category, Formatters } from '../src';
import { PassThrough } from "stream";

// Create an instance of the GoodsExporter class.
const exporter = new GoodsExporter()

const products: Product[] = [] // Put your products;
const categories: Category[] = [{ id: 1, name: 'Обувь' }]

// Call the data export method.
const stream = new PassThrough();
exporter.setExporter(() => stream);
exporter.setFormatter(new Formatters.YMLFormatter());
exporter.setTransformers([
  (products) => {
    return products.map((product) => ({
      ...product,
      price: product.price + 10000,
      images: product.images?.map((image) => image.replace("image", "pic")),
    }));
  },
]);
await exporter.export(products, categories);

Example

import fs from "fs"; // Import the 'fs' module for file writing.

// Create an instance of the GoodsExporter class.
const exporter = new GoodsExporter()

// Define an object 'transformers' that contains data transformation functions.
const transformers: Transformer[] = [
    (products) => products.map(product => ({
        ...product,
        price: product.price + 10000
    })),
    (products) => products.map(product => ({
        ...product,
        images: product.images?.map(image => image.replace("image", "pic"))
    }))
]

// Set the formatter for exporting data to YML.
exporter.setFormatter(new Formatters.YMLFormatter()) // or your own Formatter;

// Set transformers based on the specified keys.
exporter.setTransformers(transformers);

// Set an exporter that saves the data to the "output.yml" file.
exporter.setExporter(fs.createWriteStream("output.yml"));
await exporter.export(products, categories);
