Link

link is an in-memory storage layer for web apps.

It keeps data in RAM while the app is alive. When the app is about to close, suspend, or crash, link writes an encrypted snapshot to localStorage. On the next startup, it restores that snapshot back into memory and removes it from localStorage

Install

bun add @impulsedev/link

Basic usage

import { link } from "@impulsedev/link"

const store = link({
  adapter: link.adp.nextjs(),
})

await store.ready

store.set("count", 1)
store.mutate<number>("count", (current) => (current ?? 0) + 1)

console.log(store.get("count"))

Framework helpers

import { createLinkContext } from "@impulsedev/link/nextjs"
import { createLinkPlugin, useLinkValue } from "@impulsedev/link/nuxt"
import { createLinkBindings } from "@impulsedev/link/vite"
import { createLinkValue } from "@impulsedev/link/sveltekit"
import { createLinkValue as createAstroLinkValue } from "@impulsedev/link/astro"

Adapters

• link.adp.nextjs()
• link.adp.nuxt()
• link.adp.astro()
• link.adp.sveltekit()
• link.adp.vite()
• link.adp.node()

Notes

• Default persistence strategy is on-exit
• Browser adapters use encrypted snapshots
• The in-memory limit is configurable with maxBytes
• Browser storage limits are usually much smaller than the RAM limit
