3. cd node-gitlab-2-github
4. npm i

Usage

Before using this script "copy" your gitlab repo with all the branches over to github. For this create a new repo with the infos (github.owner and github.repo) from the settings.json and push all the branches you need in the new repo. (Then will the autolinking of issues to commits work.)

1. mv sample_settings.json settings.json
2. edit settings.json
3. run node index.js

Where to find info for the settings.json

gitlab

gitlab.url

The URL under which your gitlab instance is hosted.

gitlab.token

Go to your settings. Open the account tab. The private Token is the token needed.

gitlab.projectID

Leave it null for the first run of the script. Then the script will show you which projects there are.

github

github.url

Where is the github instance hosted? Default is the official api.github.com domain

github.pathPrefix

Only needed when using github enterprise and not beeing hosted at the root of the domain

github.owner

Under which organisation or user will the new project be hosted

github.repo

What is the name of the new repo

usermap

Maps the usernames from gitlab to github. If the assinee of the gitlab issue is equal to the one currently logged in github it will also get assigned without a usermap. The Mentions in issues will also be translated to the new github name.

projectmap

When one renames the project while transfering so that the projects don't loose there links to the mentioned issues.

Import limit

Because Github has a limit of 5000 Api requests per hour one has to watch out that one doesn't get over this limit. I transfered one of my project with it ~ 300 issues with ~ 200 notes. This totals to some 500 objects excluding commits which are imported through githubs importer. I never got under 3800 remaining requests (while testing it two times in one hour).

So the rule of thumb should be that one can import a repo with ~ 2500 issues without a problem.

Bugs

the milestone refs and issue refs do not seem to be rewritten properly at the moment. specifically, milestones show up like %4 in comments and issue refs like #42 do not remap to the #42 from gitlab under the new issue number in github. @ references are remapped properly (yay). If this is a deal breaker, a large amount of the code to do this has been written it just appears to no longer work in current form :(
