Capabilities

• target

Settings

A full list of supported settings and capabilities is available by running: target-csv --about

Installation

uv tool install --from meltanolabs-target-csv target-csv

Usage

You can easily run target-csv by itself or in a pipeline using Meltano.

Executing the Target Directly

target-csv --version
target-csv --help

# Test using the "Carbon Intensity" sample:
tap-carbon-intensity | target-csv --config /path/to/target-csv-config.json

# Test using the "Smoke Test" tap:
tap-smoke-test --config=tap-smoke-test-config.json | target-csv

Developer Resources

• Developer TODO: As a first step, scan the entire project for the text "TODO:" and complete any recommended steps, deleting the "TODO" references once completed.

Initialize your Development Environment

uv sync

Create and Run Tests

Create tests within the target_csv/tests subfolder and then run:

uv run pytest

You can also test the target-csv CLI interface directly using uv run:

uv run target-csv --help

Testing with Meltano

Note: This target will work in any Singer environment and does not require Meltano. Examples here are for convenience and to streamline end-to-end orchestration scenarios.

Your project comes with a custom meltano.yml project file already created. Open the meltano.yml and follow any "TODO" items listed in the file.

Next, install Meltano (if you haven't already) and any needed plugins:

uv tool install meltano

Now you can test and orchestrate using Meltano:

# Test invocation:
meltano invoke target-csv --version

# OR run a test `elt` pipeline with the Carbon Intensity sample tap:
meltano run tap-smoke-test target-csv

# Or with debug logging:
meltano --log-level=debug run tap-smoke-test target-csv
