Deno KV OAuth

Docs CI codecov

Minimal OAuth powered by Deno KV.

Note: this project is in beta. API design and functionality are subject to change.

Features

Live Demo

You can also check out a live demo at https://kv-oauth.deno.dev, which uses Github as the OAuth2 provider. Source code is located in demo.ts.

Usage

Getting Started

  1. Download demo.ts.
  2. Define your client object using one of the pre-configured OAuth2 clients or a custom OAuth2 client.
  3. Run the script with the appropriate environment variables and permission flags defined. E.g. for GitHub:
    GITHUB_CLIENT_ID=xxx GITHUB_CLIENT_SECRET=xxx deno run --unstable --allow-env --allow-net demo.ts

Pre-configured OAuth2 Clients

This module comes with a suite of pre-configured OAuth2 clients for the following providers (and their provider IDs):

  1. Discord (discord)
  2. GitHub (github)
  3. GitLab (gitlab)
  4. Google (google)
  5. Slack (slack)
  6. Twitter (twitter)

If there's a pre-configured OAuth2 client for a provider you'd like added, please submit a pull request or create a new issue.

To create a pre-configured OAuth2 client, use createClient() and define your ${PROVIDER}_CLIENT_ID and ${PROVIDER}_CLIENT_SECRET environment variables. E.g. for GitHub, your OAuth2 client object would be done by:

// GITHUB_CLIENT_ID=xxx GITHUB_CLIENT_SECRET=xxx deno run --unstable --allow-env --allow-net ...
import { createClient } from "https://deno.land/x/deno_kv_oauth/mod.ts";

const client = createClient("github");

Pass a 2nd paramter to createClient() to extend the OAuth2 client configuration. E.g. for Discord, extending the OAuth2 client object would be done by:

// DISCORD_CLIENT_ID=xxx DISCORD_CLIENT_SECRET=xxx deno run --unstable --allow-env --allow-net ...
import { createClient } from "https://deno.land/x/deno_kv_oauth/mod.ts";

const client = createClient("discord", {
  redirectUri: "http://localhost:8000/callback",
  defaults: {
    scope: "identify",
  },
});

Note: providers differ in their required OAuth parameters. createClient() throws when required OAuth configuration parameters aren't provided.

Custom OAuth2 Client

If you require custom OAuth2 configuration, you must define your client using new OAuth2Client() from the oauth2_client module. E.g.:

import { OAuth2Client } from "https://deno.land/x/oauth2_client/mod.ts";

const client = new OAuth2Client({
  clientId: Deno.env.get("CUSTOM_CLIENT_ID")!,
  clientSecret: Deno.env.get("CUSTOM_CLIENT_SECRET")!,
  authorizationEndpointUri: "https://custom.com/oauth/authorize",
  tokenUri: "https://custom.com/oauth/token",
  redirectUri: "https://my-site.com",
});
