The best API caching lib in NodeJS

forgeora — Mon, 03 Feb 2025 03:31:24 +0000

I have seen one of the library that can store our payload in memory cache & get faster response.

The library name is api-cache.

Cache a route

import express from 'express'
import apicache from 'apicache'

let app = express()
let cache = apicache.middleware

app.get('/api/collection/:id?', cache('5 minutes'), (req, res) => {
  // do some work... this will only occur once per 5 minutes
  res.json({ foo: 'bar' })
})

Cache all routes

let cache = apicache.middleware

app.use(cache('5 minutes'))

app.get('/will-be-cached', (req, res) => {
  res.json({ success: true })
})

Use with Redis

import express from 'express'
import apicache from 'apicache'
import redis from 'redis'

let app = express()

// if redisClient option is defined, apicache will use redis client
// instead of built-in memory store
let cacheWithRedis = apicache.options({ redisClient: redis.createClient() }).middleware

app.get('/will-be-cached', cacheWithRedis('5 minutes'), (req, res) => {
  res.json({ success: true })
})

Cache grouping and manual controls

import apicache from 'apicache'
let cache = apicache.middleware

app.use(cache('5 minutes'))

// routes are automatically added to index, but may be further added
// to groups for quick deleting of collections
app.get('/api/:collection/:item?', (req, res) => {
  req.apicacheGroup = req.params.collection
  res.json({ success: true })
})

// add route to display cache performance (courtesy of @killdash9)
app.get('/api/cache/performance', (req, res) => {
  res.json(apicache.getPerformance())
})

// add route to display cache index
app.get('/api/cache/index', (req, res) => {
  res.json(apicache.getIndex())
})

// add route to manually clear target/group
app.get('/api/cache/clear/:target?', (req, res) => {
  res.json(apicache.clear(req.params.target))
})

/*

GET /api/foo/bar --> caches entry at /api/foo/bar and adds a group called 'foo' to index
GET /api/cache/index --> displays index
GET /api/cache/clear/foo --> clears all cached entries for 'foo' group/collection

I recommended this api middleware you can use. in that database where they are rarely update. like country, city and validators api data.
