Installation

ExTypesense requires Elixir ~> 1.14.x. Read the Changelog for all available releases and requirements. This library is published to both Hex.pm and GitHub repository.

Add :ex_typesense to your list of dependencies in the Elixir project config file, mix.exs:

def deps do
  [
    # From default Hex package manager
    {:ex_typesense, "~> 0.3"}

    # Or from GitHub repository, if you want to latest greatest from main branch
    {:ex_typesense, git: "https://github.com/jaeyson/ex_typesense.git"}
  ]
end

Getting started

1. Add credential to config

After you have setup a local Typesense or Cloud hosted instance, you can set the following config details to the config file:

For local instance:

config :ex_typesense,
  api_key: "xyz",
  host: "localhost",
  port: 8108,
  scheme: "http"

For Cloud hosted, you can generate and obtain the credentials from cluster instance admin interface:

config :ex_typesense,
  api_key: "credential", # Admin API key
  host: "111222333aaabbbcc-9.x9.typesense.net" # Nodes
  port: 443,
  scheme: "https"

2. Create a collection

Using Ecto

In this example, we're adding person_id that points to the id of persons schema.

defmodule Person do
  use Ecto.Schema

  defimpl Jason.Encoder, for: __MODULE__ do
    def encode(value, opts) do
      value
      |> Map.take([:id, :person_id, :name, :country])
      |> Enum.map(fn {key, val} ->
        cond do
          key === :id -> {key, to_string(Map.get(value, :id))}
          key === :person_id -> {key, Map.get(value, :id)}
          true -> {key, val}
        end
      end)
      |> Enum.into(%{})
      |> Jason.Encode.map(opts)
    end
  end

  schema "persons" do
    field(:name, :string)
    field(:country, :string)
    field(:person_id, :integer, virtual: true)
  end

  def get_field_types do
    %{
      default_sorting_field: "person_id",
      fields: [
        %{name: "person_id", type: "int32"},
        %{name: "name", type: "string"},
        %{name: "country", type: "string"}
      ]
    }
  end
end

Next, create the collection from a module name.

ExTypesense.create_collection(Person)

Using Maps

schema = %{
  name: "companies",
  fields: [
    %{name: "company_name", type: "string"},
    %{name: "company_id", type: "int32"},
    %{name: "country", type: "string"}
  ],
  default_sorting_field: "company_id"
}

ExTypesense.create_collection(schema)

3. Indexing documents

For multiple documents:

Post |> Repo.all() |> ExTypesense.index_multiple_documents()

For single document:

Post |> Repo.get!(123) |> ExTypesense.create_document()

4. Search

params = %{q: "John Doe", query_by: "name"}

ExTypesense.search(schema.name, params)
ExTypesense.search(Person, params)
