Build a transform.

This command looks in the current working directory for a `transform.yaml` file. It installs the appropriate build plugin, then builds a `.wasm` file.

When invoked, it passes extra arguments directly to the underlying toolchain.

For example to add debug symbols for tinygo:

```bash
rpk transform build -- -no-debug=false
```

## [](#usage)Usage

rpk transform build [flags]
```

### [](#languages)Languages

Tinygo - By default tinygo are release builds (-opt=2) for maximum performance.
