{"id":16889,"library":"remix-auth-steam","title":"Remix Auth Steam Strategy","description":"remix-auth-steam provides a specialized authentication strategy for integrating Steam OpenID into Remix applications via the `remix-auth` library. Currently at version 1.0.4, this package acts as a bridge, enabling developers to leverage Steam's authentication flow within their Remix projects on Node.js runtimes. While it doesn't specify a strict release cadence, updates appear to be made on demand to address bug fixes, as seen in recent patch versions. Its primary differentiator is its focused implementation for Steam, building upon the extensible architecture of `remix-auth`. Developers should be aware of its specific dependency on `@remix-run/server-runtime` and `remix-auth` itself, and ensure their Remix environment is configured for server-side operations, as browser or edge worker support for Steam OpenID directly is not fully tested or guaranteed by this package. It ships with TypeScript types for improved developer experience.","status":"active","version":"1.0.4","language":"javascript","source_language":"en","source_url":"https://github.com/Andreychik32/remix-auth-steam","tags":["javascript","remix","remix-auth","auth","authentication","strategy","steam","remix-steam","typescript"],"install":[{"cmd":"npm install remix-auth-steam","lang":"bash","label":"npm"},{"cmd":"yarn add remix-auth-steam","lang":"bash","label":"yarn"},{"cmd":"pnpm add remix-auth-steam","lang":"bash","label":"pnpm"}],"dependencies":[{"reason":"Core authentication library for which this is a strategy.","package":"remix-auth","optional":false},{"reason":"Peer dependency required by Remix applications for server-side utilities like `LoaderFunction` and `createCookieSessionStorage`.","package":"@remix-run/server-runtime","optional":false}],"imports":[{"note":"Package primarily designed for ESM usage with TypeScript.","wrong":"const SteamStrategy = require('remix-auth-steam').SteamStrategy;","symbol":"SteamStrategy","correct":"import { SteamStrategy } from 'remix-auth-steam';"},{"note":"Import as a type (`import type`) for clearer separation and to avoid bundling unnecessary runtime code.","wrong":"import { SteamStrategyVerifyParams } from 'remix-auth-steam';","symbol":"SteamStrategyVerifyParams","correct":"import type { SteamStrategyVerifyParams } from 'remix-auth-steam';"},{"note":"This is a common pattern where `authenticator` is an instantiated object exported from a user-defined server module, not directly from `remix-auth-steam`.","symbol":"authenticator","correct":"import { authenticator } from '~/services/auth.server';"}],"quickstart":{"code":"import { createCookieSessionStorage, redirect } from \"@remix-run/node\";\nimport type { LoaderFunction, ActionFunction } from \"@remix-run/node\";\nimport { Authenticator } from \"remix-auth\";\nimport { SteamStrategy, SteamStrategyVerifyParams } from \"remix-auth-steam\";\nimport { useLoaderData, Form, Link } from \"@remix-run/react\";\nimport React from \"react\";\n\n// app/services/session.server.ts\n// Helper to calculate cookie expiration\nconst calculateExpirationDate = (days: number) => {\n  const expDate = new Date();\n  expDate.setDate(expDate.getDate() + days);\n  return expDate;\n};\n\n// Session storage setup\nexport let sessionStorage = createCookieSessionStorage({\n  cookie: {\n    name: \"_session\",\n    sameSite: \"lax\",\n    path: \"/\",\n    httpOnly: true,\n    secrets: [process.env.SESSION_SECRET ??
