Deno KV OAuth

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

Features

Uses oauth2_client for OAuth 2.0 workflows and Deno KV for persistent session storage.
Automatically handles the authorization code flow with Proof Key for Code Exchange (PKCE), access token refresh, and client redirection.
Comes with pre-configured OAuth 2.0 clients for popular providers.
Works locally and in the cloud, including Deno Deploy.
Based on the Request and Response interfaces from the Web API.

Live Demo

You can also check out a live demo at https://kv-oauth.deno.dev, which uses Github as the OAuth 2.0 provider. Source code is located in demo.ts.

Usage

Getting Started

Download demo.ts.
Define your client object using one of the pre-configured OAuth 2.0 clients or a custom OAuth 2.0 client.
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
```

API Reference

Check out the full documentation and API reference here.

Environment Variables

KV_PATH (optional) - defines the path that Deno KV uses. See the API reference for further details.
${PROVIDER}_CLIENT_ID and ${PROVIDER}_CLIENT_SECRET - required when creating a pre-configured OAuth 2.0 client for a given provider. E.g. for Twitter, the environment variable keys are TWITTER_CLIENT_ID and TWITTER_CLIENT_SECRET. See the list below for specifics.

Note: reading environment variables requires the --allow-env[=<VARIABLE_NAME>...] permission flag. See the manual for further details.

Pre-configured OAuth 2.0 Clients

This module comes with a suite of pre-configured OAuth 2.0 clients for the following providers:

Each function is typed so that their respective platform's requirements are met.

If there's a pre-configured OAuth 2.0 client for a provider you'd like added, please submit a pull request or create a new issue.

Custom OAuth 2.0 Client

If you require custom OAuth 2.0 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",
});
