Components for Google authentication in CommunitySolidServer.

At first, setup OAuth 2.0 at Google API Console.

• Google API Console: https://console.developers.google.com/
• Documents of Google OpenID Connect: https://developers.google.com/identity/openid-connect/openid-connect

The redirect uri should be ${Root of CommunitySolidServer}/.account/google/oidc/. Then create a directory for your project. And create a file named google-auth.json in your project directory.

{
  "@context": [
    "https://linkedsoftwaredependencies.org/bundles/npm/@solid/community-server/^7.0.0/components/context.jsonld",
    "https://linkedsoftwaredependencies.org/bundles/npm/css-google-auth/^1.0.0/components/context.jsonld",
  ],
  "import": [
    "cga:config/google-auth.json"
  ],
  "@graph": [
    {
      "@id": "urn:cga:core:MyOverride1",
      "@type": "Override",
      "overrideInstance": { "@id": "urn:cga:core:GoogleOIDC" },
      "overrideSteps": [
        {
          "@type": "OverrideParameters",
          "overrideValue": {
            "@type": "GoogleOIDC",
            "client_id": "Maybe a string that has 71 characters, and ends with apps.googleusercontent.com ."
          }
        },
        {
          "@type": "OverrideParameters",
          "overrideValue": {
            "@type": "GoogleOIDC",
            "client_secret": "Maybe a string that has 24 characters."
          }
        }
      ]
    }
  ]
}

In your project directory, execute bellow commands.

npm init -y
npm install @solid/community-server css-google-auth openid-client
npx community-solid-server -c @css:config/file.json google-auth.json -f data -m .

The CommunitySolidServer will start at http://localhost:3000/. Create an account, then go to your account page. It will contain the link "Add Google Account".

The CommunitySolidServer is developed using Components.js.

If you need to configure css-google-auth, you can use following 2 interfaces.

• GoogleAuthFilter
  • If you need to filter accounts that can register to your server, make a class implementing this interface, and exchange DefaultGoogleAuthFilter to it. You can reject by throwing an exception in your implementation.
• PostGAccountGen
  • If you need to execute some processes after adding google authentication login, you can implement this interface, and exchange DefaultGoogleAuthFilter to your implementation.
