Copy labels from one Github repository to another

README.md

Copy labels from one Github repository to another

Install dependencies npm i @octokit/rest

Generate a Github Personnal Token (starts with ghp_) and insert it in the script.

Choose the source repository and insert it in the script (e.g. kuzzleio/kuzzle)

Run the script: node copy-labels.js kuzzleio/koncorde

This will copy all labels from kuzzleio/kuzzle to kuzzleio/koncorde.

copy-labels.js

const { Octokit } = require('@octokit/rest');

const octokit = new Octokit({
  auth: 'ghp_..', // Your Personnal Token here
});

const sourceRepository = 'kuzzleio/kuzzle';

const destRepository = process.argv[2];

console.log(`Copy labels from ${sourceRepository} to ${destRepository}`);

(async () => {
  const [sourceOwner, sourceRepo] = sourceRepository.split('/');
  const [destOwner, destRepo] = destRepository.split('/');

  const res = await octokit.issues.listLabelsForRepo({ owner: sourceOwner, repo: sourceRepo })

  const labels = res.data;

  console.log(`Found ${labels.length} labels`);

  const promises = [];
  const errors = [];
  for (const label of labels) {
    promises.push(
      octokit.issues.createLabel({
        owner: destOwner,
        repo: destRepo,
        name: label.name,
        description: label.description,
        color: label.color,
      })
      .then(() => console.log(`"${label.name}" copied`))
      .catch(error => errors.push(`${label.name}: ${error.message}`))
    );
  }
  await Promise.all(promises);

  console.log(`${labels.length - errors.length} labels copied`);
