Writing Configuration

Next, we will guide you through the configuration process and explain how to use our different plugins.

The first thing to do is creating a configuration file which we will call satellite.yaml.

To avoid keeping all our files at the root of the project, we will create satellite.yaml inside a src/ folder.

In a terminal, enter the following command:

mkdir src && touch src/satellite.yaml

Then add this configuration to your YAML file:

version: '0.3'
    label: 'CSV to JSON'
        path: build
        - csv:
              file_path: 'data/products.csv'
        - json:
              file_path: 'output.json'

In our case, we use csv as an extractor and json as a loader, so we have to add the corresponding plugins to our project:

composer require php-etl/csv-plugin:'*' php-etl/json-plugin:'*'

Composer will install a version of the plugin that is compatible with the php-etl/satellite package you have previously installed. Find the different versions of our plugins here.

In a configuration file, paths start at the folder specified under filesystem.path. Here for example, the result will be src/build/output.csv.
