A simple elixir data mapper for migrating from WooCommerce to Shopify

DM

An Elixir-based application that can enrich product and related resources in Shopify based on an arbitrary source (in this case, a CSV)

Installation

If available in Hex, the package can be installed by adding elixir_data_mapper to your list of dependencies in mix.exs:

def deps do
  [
    {:elixir_data_mapper, "~> 0.1.0"}
  ]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/elixir_data_mapper.

Purpose

This application takes a flattened export of data (in this case, a CSV) and maps it to various objects in Shopify. It uses the product SKU to associate data.

For example, adding each product to many collections in Shopify, associating it to a Shopify product taxonomy, setting the "vendor" field, or setting each variant's InventoryItem country of origin.

This can be expanded for more specific mappings or data.

This application respects Shopify's rate limits.

Usage

This is not really intended to be easy to adapt to every use case. It is a good starting point for your specific business logic if you need a reference for using Shopify's APIs with Elixir.

DM.Supervisor.start_links([])
DM.sync_all

DM.Supervisor.start_links([]) will start the data mapper's shopify rate limiter supervisors for both the rest API and graphQL, using gen_source.

DM.sync_all will run the entire product sync -- it will map data from a CSV located in the /data folder and use that to push updates to matching productes or variants in Shopify.

It works by paginating products in Shopify -- it assumes products already exist there from a more basic import and need to be enriched with other data.
