Bad software is everywhere, and we’re tired of it. Sentry is on a mission to help developers write better software faster, so we can get back to enjoying technology. If you want to join us Check out our open positions

This is the official Sentry SDK for [Sentry].

💁: This README documents unreleased features (from the master branch). For documentation on the current release, see [the official documentation][docs].

Getting Started

Install

To use Sentry in your project, add it as a dependency in your mix.exs file. Sentry does not install a JSON library nor HTTP client by itself. Sentry will default to trying to use [Jason] for JSON serialization and [Hackney] for HTTP requests, but can be configured to use other ones. To use the default ones, do:

defp deps do
  [
    # ...

    {:sentry, "~> 10.0"},
    {:jason, "~> 1.4"},
    {:hackney, "~> 1.19"}
  ]
end

Configuration

Sentry has a range of configuration options, but most applications will have a configuration that looks like the following:

# config/config.exs
config :sentry,
  dsn: "https://public_key@app.getsentry.com/1",
  environment_name: Mix.env(),
  enable_source_code_context: true,
  root_source_code_paths: [File.cwd!()]

Testing Your Configuration

To ensure you’ve set up your configuration correctly we recommend running the included Mix task. It can be tested on different Mix environments and will tell you if it is not currently configured to send events in that environment:

MIX_ENV=dev mix sentry.send_test_event

Testing with Sentry

In some cases, you may want to test that certain actions in your application cause a report to be sent to Sentry. Sentry itself does this by using [Bypass]. It is important to note that when modifying the environment configuration the test case should not be run asynchronously, since you are modifying global configuration. Not returning the environment configuration to its original state could also affect other tests depending on how the Sentry configuration interacts with them. A good way to make sure to revert the environment is to use the [on_exit/2][exunit-on-exit] callback that ships with ExUnit.

For example:

test "add/2 does not raise but sends an event to Sentry when given bad input" do
  bypass = Bypass.open()

  Bypass.expect(bypass, fn conn ->
    assert {:ok, _body, conn} = Plug.Conn.read_body(conn)
    Plug.Conn.resp(conn, 200, ~s<{"id": "340"}>)
  end)

  Sentry.put_config(:dsn, "http://public:secret@localhost:#{bypass.port}/1")
  Sentry.put_config(:send_result, :sync)

  on_exit(fn ->
    Sentry.put_config(:dsn, nil)
    Sentry.put_config(:send_result, :none)
  end)

  MyModule.add(1, "a")
end

When testing, you will also want to set the :send_result type to :sync, so that sending Sentry events blocks until the event is sent.
