Migrate Releases

This is a script to migrate a Github Release from one Repo to another.

Instalation

npm i @octokit/rest semver dotenv

Usage

1. Create a .env file with the following options:

GH_AUTH_TOKEN=
SOURCE_REPO=
DESTINATION_REPO=
TAG_SHA=

2. Run migration

node migrate-releases.js

migrate-releases.js

const { Octokit } = require('@octokit/rest');
const semver = require('semver');
require('dotenv').config();

const fileSizeSI = (bytes) => {
  const size = (Math.log(bytes) / Math.log(1024)) | 0;

  return (
    (bytes / Math.pow(1024, size)).toFixed(2) +
    ' ' +
    (size ? 'KMGTPEZY'[size - 1] + 'iB' : 'Bytes')
  );
};
