Session plugin for fastify that supports both stateless and sateful sessions.
-
Requires @fastify/cookie to handle cookies.
-
Works with fastify
^4.0.0starting from>=0.16.0. -
Can leverage crypto addons like @mgcrea/fastify-session-sodium-crypto to perform crypto.
-
Can leverage store addons like:
-
Built with TypeScript for static type checking with exported types along the library.
npm install @mgcrea/fastify-session @fastify/cookie
# or
pnpm add @mgcrea/fastify-session @fastify/cookieDefaults to a volatile in-memory store for sessions (great for tests), with hmac for signature.
import createFastify, { FastifyInstance, FastifyServerOptions } from "fastify";
import fastifyCookie from "@fastify/cookie";
import fastifySession from "@mgcrea/fastify-session";
const SESSION_SECRET = "a secret with minimum length of 32 characters";
const SESSION_TTL = 86400; // 1 day in seconds
export const buildFastify = (options?: FastifyServerOptions): FastifyInstance => {
const fastify = createFastify(options);
fastify.register(fastifyCookie);
fastify.register(fastifySession, {
secret: SESSION_SECRET,
cookie: { maxAge: SESSION_TTL },
});
return fastify;
};For better performance/security, you can use the @mgcrea/fastify-session-sodium-crypto addon:
Leveraging an external redis store, the session id (generated with nanoid) is signed using a secret-key with libsodium's crytpo_auth
import createFastify, { FastifyInstance, FastifyServerOptions } from 'fastify';
import fastifyCookie from 'fastify-cookie';
import fastifySession from '@mgcrea/fastify-session';
import { SODIUM_AUTH } from '@mgcrea/fastify-session-sodium-crypto';
const SESSION_KEY = 'Egb/g4RUumlD2YhWYfeDlm5MddajSjGEBhm0OW+yo9s='';
const SESSION_TTL = 86400; // 1 day in seconds
const REDIS_URI = process.env.REDIS_URI || 'redis://localhost:6379/1';
export const buildFastify = (options?: FastifyServerOptions): FastifyInstance => {
const fastify = createFastify(options);
fastify.register(fastifyCookie);
fastify.register(fastifySession, {
key: Buffer.from(SESSION_KEY, 'base64'),
crypto: SODIUM_AUTH,
store: new RedisStore({ client: new Redis(REDIS_URI), ttl: SESSION_TTL }),
cookie: { maxAge: SESSION_TTL },
});
return fastify;
};No external store required, the entire session data is encrypted using a secret-key with libsodium's crypto_secretbox_easy
Here we used a secret instead of providing a key, key derivation will happen automatically on startup.
import createFastify, { FastifyInstance, FastifyServerOptions } from "fastify";
import fastifyCookie from "fastify-cookie";
import fastifySession from "@mgcrea/fastify-session";
import { SODIUM_SECRETBOX } from "@mgcrea/fastify-session-sodium-crypto";
const SESSION_TTL = 86400; // 1 day in seconds
export const buildFastify = (options?: FastifyServerOptions): FastifyInstance => {
const fastify = createFastify(options);
fastify.register(fastifyCookie);
fastify.register(fastifySession, {
secret: "a secret with minimum length of 32 characters",
crypto: SODIUM_SECRETBOX,
cookie: { maxAge: SESSION_TTL },
});
return fastify;
