Clone Gitlab CI variables from one Gitlab Repository to another

clonecivariables.mjs

// The following script will blindly clone all Gitlab CI variables from source repository to the target. Created this to move CI from my own repository to a client's own.
// Update the project_id/api_key (and url's if needed below), install the dependency "npm i node-fetch" and then run using node clonecivariables.mjs

import fetch from 'node-fetch'; // run in the same dir as the script: npm i node-fetch

const source_project_id = ''; // can be found on repository's home page under the repository name.
const source_api_key = '' // get one here https://gitlab.com/-/profile/personal_access_tokens (create a personal token with API scope)
const source_url = 'https://gitlab.com/'; // only need to change this if using self-hosted gitlab

const target_project_id = '';
const target_api_key = '';
const target_url = 'https://gitlab.com/'; // only need to change this if using self-hosted gitlab

const source = `${source_url}api/v4/projects/${source_project_id}/variables`;
const target = `${target_url}api/v4/projects/${target_project_id}/variables`;
