Three composable primitives — global key-value, real-time pub/sub, and unified job queues — built for Next.js and Vercel. No config files. No clusters. Just an API key.
Works with Next.js 13+ · App Router · Edge Runtime · Node.js
// Three APIs. One import.
import createClient from 'saasignal'
import NextResponse from 'next/server'
const ss = createClient(process.env.SAASIGNAL_KEY)
export async function POST(req: Request)
const orgId, metric, value = await req.json()
// Cache at the edge — 1 token
await ss.kv.set(`metric:${orgId}`, value)
// Push to live dashboards — 2 tokens
await ss.channels.publish(`org:${orgId}`,
event: 'metric.updated',
data: metric, value
)
// Queue background work — 5 tokens
await ss.jobs.create(
trigger: type: 'immediate' ,
handler: 'https://acme.com/api/process',
payload: orgId, metric, value
)
return NextResponse.json( ok: true )
Queue, Task, and Cron are not different things — they're all "execute a handler, at some point, with retries." The only difference is the trigger.
Sub-millisecond reads from 300+ edge locations. Sessions, feature flags, rate limits, distributed locks — all from a single API.
import { createClient } from 'saasignal'
const ss = createClient(process.env.SAASIGNAL_KEY)
// Edge-fast sessions
await ss.kv.set('session:u_123', {
userId: 'u_123',
role: 'admin',
plan: 'pro',
}, { ttl: 86400 })
// Atomic counters
await ss.kv.increment('ratelimit:u_123')
// Batch operations
const { results } = await ss.kv.batch([
{ op: 'get', key: 'config:flags' },
{ op: 'get', key: 'config:limits' },
])WebSocket and SSE subscriptions with presence, message history, and fan-out. Build live dashboards in minutes, not months.
// Publish from your API route
await ss.channels.publish('org:acme', {
event: 'metric.updated',
data: { mrr: 42840, delta: +1200 }
})
// Subscribe in the browser
const channel = ss.channels.subscribe('org:acme')
channel.on('metric.updated', ({ mrr, delta }) => {
setMRR(mrr)
})
// Presence — who's online right now
const { users } = await ss.channels.presence('org:acme')
console.log(users.length, 'users online')One primitive replaces three services. Immediate tasks, delayed execution, cron schedules, push queues, pull queues — all with retries and dead-letter.
// Send welcome email in background
await ss.jobs.create({
trigger: { type: 'immediate' },
handler: 'https://app.acme.com/api/on-signup',
payload: { userId: 'u_123' },
max_attempts: 3,
backoff: 'exponential',
})
// Nightly billing digest (cron)
await ss.jobs.create({
trigger: {
type: 'scheduled',
schedule: '0 9 * * *',
timezone: 'America/New_York',
},
handler: 'https://app.acme.com/api/digest',
})Sign up, create an org, then a project. Takes 30 seconds.
