This repository houses the Elixir client library for Authzed.
Authzed is a database and service that stores, computes, and validates your application's permissions.
Developers create a schema that models their permissions requirements and use a client library, such as this one, to apply the schema to the database, insert data into the database, and query the data to efficiently check permissions in their applications.
Supported client API versions:
You can find more info on each API on the Authzed API reference documentation. Additionally, Protobuf API documentation can be found on the Buf Registry Authzed API repository.
NOTE: Current Authzed SDK commit version on Buf available here
If you're using a local SpiceDB instance, you can start the instance with Docker and Docker Compose using the command:
make start-infraThe package can be installed by adding authzed to your list of dependencies in mix.exs:
def deps do
[
{:authzed, "~> 0.0.1"}
]
endIn order to successfully connect, you will have to provide a Bearer Token with your own API Token from the Authzed dashboard in place of somerandomkeyhere in the following example:
alias Authzed.Api.V1.{Client, GRPCUtil}
client = Client.new(
"localhost:50051",
GRPCUtil.insecure_bearer_auth_token("somerandomkeyhere")
)alias Authzed.Api.V1.{
CheckPermissionRequest,
ObjectReference,
SubjectReference,
}
# Is Emilia in the set of users that can read post #1?
post_one = ObjectReference.new(object_type: "post", object_id: "1")
emilia =
SubjectReference.new(object: ObjectReference.new(object_type: "user", object_id: "emilia"))
{:ok, response} =
client.permissions_service.check_permission(
client.channel,
CheckPermissionRequest.new(
resource: post_one,
permission: "view",
subject: emilia
)
)
assert response.permissionship == :PERMISSIONSHIP_HAS_PERMISSIONSince version 0.0.6 telemetry events are published by the GRPC library.
See docs for details.
Run the tests using the command:
make run-tests- Note that this will create a SpiceDB instance with the option
serve-testing. creating an in-memory spicedb server which serves completely isolated datastores per client-supplied auth token used.
We use Buf to generate the protobuf and GRPC definitions for Elixir. You can use the command
make generateto regenerate the definitions and move them to their respective folders.
NOTE
- Install protoc-gen-elixir using the instructions in the Elixir Protobuf Repository
- If you're using asdf to manage elixir versions, run the command
asdf reshim elixirto add theprotoc-gen-elixirexecutable to the PATH.
