DatoCMS Client

Provices access to data in a DatoCMS site.

Installation

The package can be installed by adding datocms_client to your list of dependencies in mix.exs:

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

Configuration

Via config.exs

Assuming your config/config.exs includes environment-specific secrets files excluded from your repo, put the following in {dev|production}.secrets.exs:

config :datocms_client, :api_config,
  %{headers: ["Authorization": "Bearer nnnnnnnnnnnnnnnnnnnnn"]}

Where nnnnnnnnnnnnnnnnnnnnn should be replaced by either your read-write or read-only DatoCMS API key.

If you are only reading data, you can use your read-only access token.

If you see timeout errors when downloading data, add the following:

config :datocms_client, :api_config,
  %{
    headers: ["Authorization": "Bearer nnnnnnnnnnnnnnnnnnnnn"],
    options: [recv_timeout: :infinity]
  }

Programmatically

Application.put_env(
  :my_client,
  :api_config,
  %{
    headers: ["Authorization": "Bearer nnnnnnnnnnnnnnnnnnnnn"],
    options: [recv_timeout: :infinity]
  }
)

Overview

DatoCMS.Client

This module contains a REST client for the datocms.com API. The code is generated by the json_hyperschema_client_builder.

The generated documentation can be found at https://hexdocs.pm/datocms_client.

DatoCMS

Provides access to the main data access functionality:

• start/1, start/2 - start the DatoCMS Repo process,
• load/0 - download all site data, internallize it and store it in the Repo,
• put/1 - overwrite the data in the Repo with the supplied values,
• all/0 - retrieve the data in the Repo,
• cache/0 - copy all Repo data to a file on disk,
• load_from_cache/0 - the data from the file on disk and store it in the Repo.

Calling load/0 downloads site.json from the DatoCMS API plus all (paginated) items.json files.

DatoCMS.Repo

Internalized Data

All data is held in Elixir Map structues with atom keys.

A site's data is stored internally as a keyword list containing 3 data structures:

• :site - general information about the site;
• :item_types_by_type - the structure of each item type, keyed by the item type (atom);
• :items_by_type - the data, grouped by item type, keyed by the item type (atom).
