Export/import github labels

index.js

// go on you labels pages
// eg https://github.com/cssnext/cssnext/labels
// paste this script in your console
// copy the output and now you can import it using https://github.com/popomore/github-labels !

var labels = [];
[].slice.call(document.querySelectorAll(".label-link"))
.forEach(function(element) {
  labels.push({
    name: element.textContent.trim(),
    // using style.backgroundColor might returns "rgb(...)"
    color: element.getAttribute("style")
      .replace("background-color:", "")
      .replace(/color:.*/,"")
      .trim()
      // github wants hex code only without # or ;
      .replace(/^#/, "")
      .replace(/;$/, "")
      .trim(),
  })
})
console.log(JSON.stringify(labels, null, 2))

tl;dr gh label clone src-org/src_repo --repo dest-org/dest_org

If you're coming by this thread in 2024 or later, I highly recommend seeing the official GitHub CLI [1].

[1] https://cli.github.com/manual/gh_label_clone

1. Install this for your repository : https://probot.github.io/apps/settings/

2. Go to any repo from where you want to extract the labels
   e.g https://github.com/maheshj01/pastelog/issues/labels

3. paste the below script in the chrome console

below script extracts the labels and generates output in yml format

var labels = [];

function hex(x) {
    return ("0" + parseInt(x).toString(16)).slice(-2);
}

function rgba2hex(rgba) {
    rgba = rgba.match(/^rgba?\((\d+),\s*(\d+),\s*(\d+)(,\s*\d+\.*\d+)?\)$/);
    return hex(rgba[1]) + hex(rgba[2]) + hex(rgba[3]);
}

[].slice.call(document.querySelectorAll(".js-label-link"))
.forEach(function(element) {
  labels.push({
    name: element.textContent.trim(),
    description: element.parentElement.nextElementSibling.firstElementChild.innerText.trim(),
    // Extract color using rgba2hex function
    color: rgba2hex(window.getComputedStyle(element).getPropertyValue("background-color")),
  })
});

let yamlOutput = labels.map(label =>
  `- name: ${label.name}\n  description: ${label.description}\n  color: ${label.color}`
).join("\n");

console.log(yamlOutput);

4. copy the output and go to your repository and create .github/settings.yaml and paste the labels copied in step 3

sample settings.yml for all configurations for this settings refer link in step 1

  name: repo-name
