Typesense client for Elixir with support for your Ecto schemas.
Note: Breaking changes if you're upgrading from 0.3.x to upcoming 0.5.x version.
- creating collection using auto schema detection
- implement multisearch
- implement geosearch
- implement curation
- implement synonyms
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, "~> 0.4"}
# Or from GitHub repository, if you want to latest greatest from main branch
{:ex_typesense, git: "https://github.com/jaeyson/ex_typesense.git"}
]
enddocker compose up -dMore info on spinning a local instance: https://typesense.org/docs/guide/install-typesense
After you have setup a local Typesense or Cloud hosted instance, there are 2 ways to set the credentials:
You can set the following config details to the config file:
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"By default you don't need to pass connections every time you use a function, if you use "Option 1" above.
You may have a Connection Ecto schema in your app and want to pass your own creds dynamically.
defmodule MyApp.Credential do
schema "credentials" do
field :node, :string
field :secret_key, :string
field :port, :integer
end
endcredential = MyApp.Credential |> where(id: ^8888) |> Repo.one()
# using Connection struct
conn = %ExTypesense.Connection{
host: credential.node,
api_key: credential.secret_key,
port: credential.port,
scheme: "https"
}
# or maps, as long as the keys matches in ExTypesense.Connection.t()
conn = %{
host: credential.node,
api_key: credential.secret_key,
port: credential.port,
scheme: "https"
}
# or convert your struct to map, as long as the keys matches in ExTypesense.Connection.t()
conn = Map.from_struct(MyApp.Credential)
# or you don't want to change the fields in your schema, thus you convert it to map
conn = %Credential{
node: "localhost",
secret_key: "xyz",
port: 8108,
scheme: "http"
}
conn =
conn
|> Map.from_struct()
|> Map.drop([:node, :secret_key])
|> Map.put(:host, conn.node)
|> Map.put(:api_key, conn.secret_key)
ExTypesense.search(conn, collection_name, query)There are 2 ways to create a collection, either via Ecto schema or using map (an Elixir data type):
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
endNext, create the collection from a module name.
ExTypesense.create_collection(Person)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)For multiple documents:
Post |> Repo.all() |> ExTypesense.index_multiple_documents()For single document:
Post |> Repo.get!(123) |> ExTypesense.create_document()params = %{q: "John Doe", query_by: "name"}
ExTypesense.search(schema.name, params)
ExTypesense.search(Person, params)Check Cheatsheet for more usage examples.
