newredis v1.11.1
A Modern Redis Client
Introduction
This is a pure Javascript based redis client(including a connection pool implementation). All code are written in the newest JS standard (async/await & Promise). All related exceptions and events are handled so you can write you code as easy as possible.
Usage
There are two class exported by this package: RedisConnection
and RedisPool
. I will suggest using RedisPool
only, because it contains broken connection repairing, which is important in production environment. Besides, the API is pretty simple.
First, install it through npm:
npm install newredis
Then import the library and create a client like this:
const { RedisPool } = require("newredis")
const pool = new RedisPool({ port: 6379, host: "localhost", password: "asdf" })
If you are using the default host(localhost) and default port(6379), you can simply write:
const pool = new RedisPool({ password: "asdf" })
If the requirepass
in redis configuration is not enabled, you can even write:
const pool = new RedisPool()
Now you can use it in Promise way:
pool.getConnection()
.then(conn => {
return conn.execute([ "get", "hello" ]).then(r => [ conn, r ])
})
.then(([ conn, r ]) => {
conn.release()
console.log("R:", r)
})
.catch(e => {
console.error("E:", e)
})
Or in async/await way:
async function testConn() {
const conn = await pool.getConnection()
const r = await conn.execute([ "get", "hello" ])
console.log("R:", r)
conn.release()
}
testConn()
.catch(e => console.error("E:", e))
If you really want to use RedisConnection
instead of RedisPool
, there are some examples in test directory.
