Typesense client for Elixir with support for your Ecto schemas.
Note: Breaking changes if you're upgrading from
0.3.x
to0.5.x
version and above.
- creating collection using auto schema detection
- 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, "~> 0.7"}
# Or from GitHub repository, if you want to latest greatest from main branch
{:ex_typesense, git: "https://github.com/jaeyson/ex_typesense.git"}
]
end
docker compose up -d
More info on spinning a local instance: https://typesense.org/docs/guide/install-typesense.html
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:
if config_env() == :prod do # if you'll use this in prod environment
config :ex_typesense,
api_key: "xyz",
host: "localhost",
port: 8108,
scheme: "http",
options: %{}
...
Note: The
options
key can be used to pass additional configuration options such as custom Finch instance or receive timeout settings. You can add any options supported by Req here. For more details check Req documentation.
Note: If you use this for adding test in your app, you might want to add this in
config/test.exs
:
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",
options: %{}
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
end
As long as the keys matches in ExTypesense.Connection.t()
:
credential = MyApp.Credential |> where(id: ^8888) |> Repo.one()
conn = %{
host: credential.node,
api_key: credential.secret_key,
port: credential.port,
scheme: "https"
}
# NOTE: create a collection and import documents
# first before using the command below
ExTypesense.search(conn, collection_name, query)
Or convert your struct to map, as long as the keys matches in ExTypesense.Connection.t()
:
conn = Map.from_struct(MyApp.Credential)
# NOTE: create a collection and import documents
# first before using the command below
ExTypesense.search(conn, collection_name, query)
Or you don't want to change the fields in your Ecto 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)
# NOTE: create a collection and import documents
# first before using the command below
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 persons_id
that points to the id of persons
schema.
Note: we're using
<TABLE_NAME>_id
. If you have table e.g. namedpersons
, it'll bepersons_id
.
defmodule Person do
use Ecto.Schema
@behaviour ExTypesense
defimpl Jason.Encoder, for: __MODULE__ do
def encode(value, opts) do
value
|> Map.take([:id, :persons_id, :name, :country])
|> Enum.map(fn {key, val} ->
cond do
key === :id -> {key, to_string(Map.get(value, :id))}
key === :persons_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(:persons_id, :integer, virtual: true)
end
@impl ExTypesense
def get_field_types do
primary_field = __MODULE__.__schema__(:source) <> "_id"
%{
# Or might as well just write persons_id instead. Up to you.
default_sorting_field: primary_field,
fields: [
%{name: primary_field, type: "int32"},
%{name: "name", type: "string"},
%{name: "country", type: "string"}
]
}
end
end
Next, create the collection from a module name.
ExTypesense.create_collection(Person)
schema = %{
name: "companies",
fields: [
%{name: "company_name", type: "string"},
%{name: "companies_id", type: "int32"},
%{name: "country", type: "string"}
],
default_sorting_field: "companies_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.
For instance, in a scenario where an application has multiple Finch pools configured for different services, a developer might want to specify a particular Finch pool for the HttpClient
to use. This can be achieved by configuring the options as follows:
config :ex_typesense,
api_key: "XXXXXX",
#...
options: [finch: MyApp.CustomFinch]
In this example, MyApp.CustomFinch
is a custom Finch pool that the developer has configured with specific connection options or other settings that differ from the default Finch pool.
