pub-pkg-google-oauth

installation

This package is included with pub-server. It can be activated by including it as a theme on the command line or in pub-config.

pub -t pub-pkg-google-oauth

credentials

pub-pkg-google-oauth requires the client ID and a client secret to be specified as environment variables GID and GCS respectively.

export GID={client_ID}
export GCS={client_secret}

configuring your app URL endpoint

oauth requires an endpoint for the protocol to redirect to after authenticating. In addition, google will not allow a site to authenticate with oauth unless the site has been registered as a "javascript origin".

If you are using heroku, you can use your heroku app URL for this.

If you are running on your own machine over a local area network (or on wifi), you will need to configure a tunnel service like localtunnel.me so that your server can be reached from the Internet.

npm install -g localtunnel
lt --port 3001 --subdomain {yourname}

In either case, once you know your app URL, you can configure pub-server and pub-pkg-google-auth to use it by setting the APP environment variable. E.g.

export APP=https://{yourname}.localtunnel.me

oauth configuration on google

  • use the google developers console and create project if you don't already have one

  • make sure that the Google+ API is enabled

  • under Credentials, create a new Client ID (type Web Application)

  • enter a project name in the consent screen

  • set the Javascript origin to match your app URL

  • set the Redirect URI to {your app url}/server/auth/google/callback

  • note the new Client ID and Client secret

configuring google email addressses to access pub-server

ACLs are configured using environment variables ACL_ADMIN, ACL_EDIT, and ACL_READ. These contain comma-separated lists of users.

E.g. To grant yourself admin rights, and 3 other users read access:

export ACL_ADMIN={your-email}
export ACL_READ={email-1},{email-2},{email-3}

You can also open public/anonymous access to non-protected pages by running pub -P or setting opts.publicPages

to test locally

  • make sure you have set environment variables GID, GCS, APP, and ACL_ADMIN (or some other ACL_)
  • start localtunnel or similar service
  • start pub-server with google oauth
$ pub -t pub-pkg-google-oauth
  • now point your browser to https://{yourname}.localtunnel.me

  • when running with auth, the default behavior is to require authentication for all pages

  • you should see a login prompt

  • this will be followed by the google oauth confirmation

  • if all is well you will then be able to read the markdown page in the directory where pub was launched.

  • if you have not configured the access properly for this email you will see another login prompt
