:pushpin: Which module should I use? What is abstract-level? Head over to the FAQ.

Usage

const { RedisLevel } = require('upstash-redis-level')
const { Redis } = require('@upstash/redis')
const db = new RedisLevel({
  redis: new Redis({
    url: process.env.KV_REST_API_URL || 'http://localhost:8079',
    token: process.env.KV_REST_API_TOKEN || 'example_token',
  }),
  debug: process.env.DEBUG === 'true' || false,
})

// Add an entry with key 'a' and value 1
await db.put('a', 1)

// Add multiple entries
await db.batch([{ type: 'put', key: 'b', value: 2 }])

// Get value of key 'a': 1
const value = await db.get('a')

// Iterate entries with keys that are greater than 'a'
for await (const [key, value] of db.iterator({ gt: 'a' })) {
  console.log(value) // 2
}

API

The API of upstash-redis-level follows that of abstract-level with three additional constructor options (see below).

db = new RedisLevel([options])

Besides abstract-level options, the optional options object may contain:

• redis: an instance of @upstash/redis client
• debug: a boolean to enable debug logs
• namespace: a string to prefix all keys with. The default is level

Querying Redis Level with Redis commands
