```

--------------------------------

### Install and Build Project Assets

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/README.md

Install and build the JavaScript and CSS assets required for the Web UI. This command should be run after initial setup or when updating dependencies.

Start the development server using the provided dev.exs script, which is based on Phoenix Playground.

```bash
iex dev.exs
```

--------------------------------

### Install ErrorTracker after adding dependencies

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Run this command after adding `error_tracker` and `igniter` to your dependencies in `mix.exs`.

```bash
mix error_tracker.install
```

--------------------------------

### Install ErrorTracker using Igniter

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Use this command to automatically install and configure ErrorTracker if Igniter is already available in your project.

```bash
mix igniter.install error_tracker
```

--------------------------------

### Watch for Asset Changes

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/README.md

Start the asset watcher to automatically recompile CSS when changes are made to Tailwind CSS classes. Run this in a separate terminal.

```bash
mix assets.watch
```

--------------------------------

### Integrate ErrorTracker with Phoenix Endpoint

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Include this integration in your `Phoenix.Endpoint` module to track errors that occur before the Phoenix router starts handling requests.

```elixir
defmodule MyApp.Endpoint do
  use Phoenix.Endpoint
  use ErrorTracker.Integrations.Plug

  # Your code here
end
```

--------------------------------

### Download Project Dependencies

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/README.md

Download all necessary project dependencies using Mix.

```bash
mix deps.get
```

--------------------------------

### Apply database migrations

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Execute this command to run all pending Ecto migrations, including the one for ErrorTracker.

```bash
mix ecto.migrate
```

--------------------------------

### Configure ErrorTracker settings

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Add these configuration options to your `config/config.exs` file to set the repository, OTP app, and enable/disable tracking.

```elixir
config :error_tracker,
  repo: MyApp.Repo,
  otp_app: :my_app,
  enabled: true
```

--------------------------------

### Add ErrorTracker and Igniter to dependencies

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Add these dependencies to your mix.exs file if the `igniter.install` escript is not available. Ensure to run `mix deps.get` afterwards.

```elixir
 {:error_tracker, "~> 0.9"},
 {:igniter, "~> 0.5", only: [:dev]},
```

--------------------------------

### Generate Ecto migration for ErrorTracker

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Run this command to generate a new Ecto migration file for adding ErrorTracker's database tables.

```bash
mix ecto.gen.migration add_error_tracker
```

--------------------------------

### Declare ErrorTracker as a dependency

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Add this to your `mix.exs` file to include ErrorTracker as a project dependency.

```elixir
# mix.exs
defp deps do
  [
    {:error_tracker, "~> 0.9"}
  ]
end
```

--------------------------------

### Integrate ErrorTracker with Plug Router

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Add this integration to your `Plug.Router` module if your application uses Plug but not Phoenix, to enable error tracking.

```elixir
defmodule MyApp.Router do
  use Plug.Router
  use ErrorTracker.Integrations.Plug

  # Your code here
end
```

--------------------------------

### Manually Report Errors

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Use `ErrorTracker.report/2` to manually report an exception and its stack trace. This is useful for errors outside default integration scopes.

```elixir
try do
  # your code
catch
  e ->
    ErrorTracker.report(e, __STACKTRACE__)
end
```

--------------------------------

### Define ErrorTracker migration functions

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Implement the `up` and `down` functions in the generated migration file to manage ErrorTracker's database schema.

```elixir
defmodule MyApp.Repo.Migrations.AddErrorTracker do
  use Ecto.Migration

  def up, do: ErrorTracker.Migration.up(version: 5)

  # We specify `version: 1` in `down`, to ensure we remove all migrations.
  def down, do: ErrorTracker.Migration.down(version: 1)
end
```

--------------------------------

### Set Custom Context for Errors

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Use `ErrorTracker.set_context/1` to add custom information, like a user ID, to errors occurring in the current process. This context is merged with default integrations.

```elixir
ErrorTracker.set_context(%{user_id: conn.assigns.current_user.id})
```

--------------------------------

### Define Custom Error Ignoring Logic

Source: https://github.com/elixir-error-tracker/error-tracker/blob/main/guides/Getting Started.md

Implement the `ErrorTracker.Ignorer` behaviour to define custom logic for ignoring specific errors. This prevents ignored errors from being tracked.

```elixir
defmodule MyApp.ErrorIgnores do
  @behaviour ErrorTracker.Ignorer

  @impl ErrorTracker.Ignorer
  def ignore?(%{kind: "Elixir.UnreliableThirdParty.Error", reason: ":timeout"} = _error, _context) do
    true
  end
end
```
