# `Alaja.CLI.Commands.Action`
[🔗](https://github.com/Lorenzo-SF/alaja/blob/2.1.0/lib/alaja/cli/commands/action.ex#L1)

`alaja action` — Execute Alaja commands from JSON input.

Accepts JSON from stdin, a file, or inline data and dispatches commands
to `Alaja.CLI.exec/1` (in-process). Supports single actions and batch
operations.

## Performance

Batch execution uses `Alaja.CLI.exec/1` which **does not re-start the
application stack** for each element. This makes batch actions
dramatically faster than the historical implementation (which called
`Alaja.CLI.main/1` and paid the boot cost on every invocation).

## Examples

    echo '{"command": "success", "args": ["Done!"]}' | alaja action
    alaja action --file actions.json
    alaja action --data '{"command": "info", "args": ["Processing..."]}'
    alaja action --data '{"actions":[...]}' --stop-on-error
    alaja action --data '{"actions":[...]}' --parallel 4
    alaja action --data '{"actions":[...]}' --dry-run

# `help`

```elixir
@spec help() :: :ok
```

Prints help for the `alaja action` command.

# `run`

```elixir
@spec run([String.t()]) :: :ok | no_return()
```

Runs the `alaja action` command.
