Nice, works well. It is possible to add a flag to clear all existing flags before importing new ones

With some changes in github classnames:

[
  {
    "name": "bugfix",
    "color": "eb6420"
  },
  {
    "name": "feature",
    "color": "0e8a16"
  },
  {
    "name": "hotfix",
    "color": "e11d21"
  }
].forEach(function(label) {
  addLabel(label)
})

function updateLabel (label) {
  var flag = false;
  [].slice.call(document.querySelectorAll(".labels-list-item"))
  .forEach(function(element) {
    if (element.querySelector('.label-link').textContent.trim() === label.name) {
      flag = true
      element.querySelector('.js-edit-label').click()
      element.querySelector('.js-new-label-name-input').value = label.name
      element.querySelector('.js-new-label-color-input').value = '#' + label.color
      element.querySelector('.js-edit-label-cancel ~ .btn-primary').click()
    }
  })
  return flag
}

function addNewLabel (label) {
  document.querySelector('.js-new-label-name-input').value = label.name
  document.querySelector('.js-new-label-color-input').value = '#' + label.color
  document.querySelector('.js-details-target ~ .btn-primary').click()
}

function addLabel (label) {
  if (!updateLabel(label)) addNewLabel(label)
}

Very nice. Thanks!

Trying it again recently, I needed to add document.querySelector('.js-details-target ~ .btn-primary').disabled = false before the click() to get it to work (using @mqklin updated code).

I added two lines so the script now also works with descriptions. This includes Igelfan's fix.

// append this to the array returned from the label getter at the bottom
.forEach(function(label) {
addLabel(label)
})

function updateLabel (label) {
  var flag = false;
  [].slice.call(document.querySelectorAll(".labels-list-item"))
  .forEach(function(element) {
    if (element.querySelector('.label-link').textContent.trim() === label.name) {
      flag = true
      element.querySelector('.js-edit-label').click()
      element.querySelector('.js-new-label-name-input').value = label.name
      element.querySelector('.js-new-label-description-input').value = label.description
      element.querySelector('.js-new-label-color-input').value = '#' + label.color
      element.querySelector('.js-edit-label-cancel ~ .btn-primary').click()
    }
  })
  return flag
}

function addNewLabel (label) {
  document.querySelector('.js-new-label-name-input').value = label.name
  document.querySelector('.js-new-label-description-input').value = label.description
  document.querySelector('.js-new-label-color-input').value = '#' + label.color
  document.querySelector('.js-details-target ~ .btn-primary').disabled = false
  document.querySelector('.js-details-target ~ .btn-primary').click()
}

function addLabel (label) {
  if (!updateLabel(label)) addNewLabel(label)
}

Getting the labels from source repo, with descriptions:

var labels = [];
[].slice.call(document.querySelectorAll(".label-link"))
.forEach(function(element) {
  labels.push({
    name: element.textContent.trim(),
    description: element.getAttribute("aria-label"),
    // 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))

Thanks for this! Very helpful

Amazing! Thank you!

Thanks a lot. I have added my own labels to add priority labels and change some default GitHub label color:

Hey all, very helpful. When I tried the updates to include the descriptions the code wasn't quite working (getting null for all descriptions). I only slightly modified the code for getting the labels from the source repo. The following code worked for me.

var labels = [];
[].slice.call(document.querySelectorAll(".label-link"))
.forEach(function(element) {
  labels.push({
    name: element.textContent.trim(),
    description: element.getAttribute("title"),
    // 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))

This is great. It would be nice to have the script replace colors and descriptions of custom labels as well.

Thank you all! This is so handy - using @NillerMedDild's combo solution currently

Thanks, very helpful.

This is the code with updated GitHub classes (js- prefix), tested and works:

function updateLabel(label) {
  var flag = false;
  [].slice
    .call(document.querySelectorAll(".js-labels-list-item"))
    .forEach(function (element) {
      if (
        element.querySelector(".js-label-link").textContent.trim() === label.name
      ) {
        flag = true;
        element.querySelector(".js-edit-label").click();
        element.querySelector(".js-new-label-name-input").value = label.name;
        element.querySelector(".js-new-label-description-input").value = label.description;
        element.querySelector(".js-new-label-color-input").value = "#" + label.color;
        element.querySelector(".js-edit-label-cancel ~ .btn-primary").click();
      }
    });
  return flag;
}

function addNewLabel(label) {
  document.querySelector(".js-new-label-name-input").value = label.name;
  document.querySelector(".js-new-label-description-input").value = label.description;
  document.querySelector(".js-new-label-color-input").value = "#" + label.color;
  document.querySelector(".js-details-target ~ .btn-primary").disabled = false;
  document.querySelector(".js-details-target ~ .btn-primary").click();
}

function addLabel(label) {
  if (!updateLabel(label)) addNewLabel(label);
}

// Your labels
[]
.forEach(function (label) {
  addLabel(label);
});

I've cleaned up and updated this code and the exporter to work with Github's new classes and style variables, and added a new "remove existing" option to the label exporter script. You can find them at these gists:

Label exporter
Label importer

@AHilyard I tried the importer, it works like a charm!
Thanks!!

@AHilyard Thanks !!

Ahh.. Looks like this is receiving a 422 Error.
