library0.5.10jsnpmunverified

Extensions for svelte-adapter-uws providing Redis and Postgres-backed features: distributed pub/sub, replay buffers, presence tracking, rate limiting, groups, and database change notifications. Current stable version is 0.5.10 with rough monthly releases. Unlike standalone WebSocket managers, this integrates natively with SvelteKit's adapter lifecycle and uses uWebSockets.js directly. Requires Node >=22 and peer dependency svelte-adapter-uws ^0.5.8.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

redisExtensions

✓ import { redisExtensions } from 'svelte-adapter-uws-extensions'

✗ const redisExtensions = require('svelte-adapter-uws-extensions').redisExtensions

ESM-only package; CommonJS require will fail.

postgresExtensions

✓ import { postgresExtensions } from 'svelte-adapter-uws-extensions'

✗ import { PostgresExtensions } from 'svelte-adapter-uws-extensions'

Named export is camelCase, not PascalCase.

createAdapter

✓ import { createAdapter } from 'svelte-adapter-uws'

✗ import { createAdapter } from 'svelte-adapter-uws-extensions'

createAdapter is part of the base adapter package, not extensions.

Initialize Redis-based extensions (pub/sub, presence, replay, rate limit, groups) and attach them to the SvelteKit adapter.

import { redisExtensions } from 'svelte-adapter-uws-extensions'; import { createAdapter } from 'svelte-adapter-uws'; import Redis from 'ioredis'; const redis = new Redis(process.env.REDIS_URL ?? ''); const extensions = redisExtensions({ redis, prefix: 'myapp', }); export default createAdapter({ extensions: [extensions], });

Debug

Known issues

breakingPackage is ESM-only and requires Node >=22.

fix

Set "type": "module" in package.json or use .mjs files. Upgrade Node to v22+.

affects: >=0.0.0

gotcharedisExtensions and postgresExtensions must be called with required options; missing 'redis' or 'pg' client throws runtime error.

fix

Always pass a configured Redis or PG client instance.

affects: >=0.0.0

gotchaExtensions are applied globally within the adapter; using multiple instances may cause conflicts.

fix

Only create one extension instance per app, or use distinct prefixes.

affects: >=0.0.0

deprecatedOption 'channelPrefix' renamed to 'prefix' in v0.5.0.

fix

Use 'prefix' instead of 'channelPrefix'.

affects: <0.5.0
