Insert product using shopify

I'm trying to add a curl product with rest api in shopify using node js with graphql.There is a problem related to the product description part.

In this format I send the description, it also contains html elements.

Graphql query const { decode } = require('html-entities'); static create_simple_product(data){

  let decoded_desc = decode(data.body_html);
 
  const prodQuery = `
    mutation {
      productCreate(
        input: {
          title: "${data.title}", 
          productType: "${data.product_type}", 
          vendor: "${data.vendor}",
          status:${statusData},
          bodyHtml: "${decoded_desc.replace(/"/g, '\\"')}",
          tags:"${typeof data.tags !== 'object' ? "" :  data.tags}",
          handle:"${data.handle}",
          seo: {description: "${data.seo_description}", title: "${data.seo_title}"},
          published:true
        }
        media: {originalSource: "${data.images[0]}", mediaContentType: IMAGE, alt: "${data.title}"}
      ) {

            edges {
              node {
                id
                ... on MediaImage {

  return prodQuery;
}

The api body that I send from php.

 $output_desc_prod = preg_replace('/<([^>]+)(\sstyle=(?P<stq>["\'])(.*)\k<stq>)([^<]*)>/iUs', '<$1$5>', $get_product_data->descriere_produs);
     
        $product_description = htmlentities($output_desc_prod); 
       

        $data_sf_prod = array(
            "api_key" => $site_data->api_key,
            "server_key" =>  $site_data->server_key,
            "title" =>  $get_product_data->nume_produs,
            "body_html" => $product_description,
            "vendor" => strtolower($site_data->den_site),
            "status" => "draft",
            "product_type" => "",
            "tags" => "",
            "images" => $array_images_final,
            "seo_description" => $getMetaData->md,
            "seo_title" => $getMetaData->mt,
            "price" => $priceSelector,
            "sku" => $get_product_data->cod_produs,
            "handle"=> $get_product_data->slug_produs,
            "barcode" =>  $get_product_data->ean === "" ? null : $get_product_data->ean,
            "weight" => 1,
            "weight_unit" => "",
            "compare_at_price" => $priceCompareSelector
        );

I use htmlentities to eliminate any problem, mostly it works, but there are some products that once inserted don't work and display the following error. Create Simple ProductError: syntax error, unexpected invalid token (""") at [9, 25]

This isn't necessarily the answer to the question you're asking, but it might solve your problem. Please don't do string interpolation on your GraphQL operations. You should be passing a query and a variables to your backend. query will use GraphQL variable references, and the variables will be a JSON object with the content.

This has several benefits, including:

1. Persisted Queries: at build time, you are able to register your query body and get back a hash. Then, when you make your GraphQL request, you only have to send the hash and the variables. This reduces bytes-over-the-wire and generally increases the speed of the application.
2. You don't have to worry about string interpolation and quotes (the issue it sounds like you're having). As long as you can correctly JSON-stringify your parts, you don't have to worry about the end result ALSO having to go through JSON-stringification.
3. Along with #2, you don't have to do "HTML encoding" yourself on the frontend. variables will be run through JSON.stringify, and that function is smarter than I am about what works with JSON and what doesn't.

Your query:

mutation CreateAProduct($productInput: ProductCreateInput!, $mediaInput: MediaCreateInput!) {
  productCreate(
    input: $productInput
    media: $mediaInput
  ) {
    # Whatever you want, or
    # ...thisCouldBeAFragment
}

Your variables

const variables = {
  productInput: {
    title: data.title,
    productType: data.product_type,
    vendor: data.vendor,
    status: statusData,
    bodyHtml: data.description,
    tags: typeof data.tags !== 'object' ? "" :  data.tags,
    handle: data.handle,
    seo: {description: data.seo_description, title: data.seo_title},
    published: true
  },
  mediaInput: {
    originalSource: data.images[0],
    mediaContentType: "IMAGE",
    alt: data.title
  }
};

As mentioned in #3, note that I just used data.description. Since variables is going to be run through JSON.stringify, you don't have to "manually figure out yourself" how to make that work as part of your request body.
