用 TypeScript 为 Deno 平台做了一个 Tiny Redis

https://github.com/qingant/tiny-redis

如果你安装了Deno的话，可以用一行命令启动一个 Redis 实例：

deno -A https://raw.githubusercontent.com/qingant/tiny-redis/master/mod.ts -h 127.0.0.1 -p 6666 

当然现在只有有限的几个命令，不过我会在后面逐步补充完整。TinyRedis 目前不是为了做一个 product ready 的 Redis 替代品，而是为了学习、展示如何用 TypeScript 和 Deno 做网络编程。你可以用 TinyRedis 来构造你自己的 Redis like 应用，例如，跑在浏览器里的 Redis，或者写一个 Redis Client 。

示例：

Client Sample:

// also you can run this by `deno -A https://raw.githubusercontent.com/qingant/tiny-redis/master/samples/cli.ts` import { encode, RedisValueOf, RedisParser, show } from 'https://raw.githubusercontent.com/qingant/tiny-redis/master/mod.ts'; const main = async () => { const opts = { port: 6379, hostname: "127.0.0.1" }; // connect to redis server const cOnn= await Deno.connect(opts); // create a redis command and encode it to [Uint8Array] const cmdEncoded = encode(RedisValueOf.array([ "INFO", "MEMORY" ])); // send the command to redis server for (let i in cmdEncoded) { await conn.write(cmdEncoded[i]); } // create a parser and get the result const p = new RedisParser(conn); const req = await p.parse(); console.log(show(req)); }; await main(); 

Server Side (if you want to implement something that talks redis protocol , Look at this):

import {RedisArray, RedisValue, RedisClient, RedisValueOf, BaseHandler} from 'https://raw.githubusercontent.com/qingant/tiny-redis/master/mod.ts'; class MyHandler extends BaseHandler { commands = { 'TINY': this.command_TINY } private async command_TINY(request: RedisArray): Promise<RedisValue> { return RedisValueOf.string('REDIS'); } } const main = async () => { const opts = { port: 6666, hostname: "0.0.0.0" }; const listener = Deno.listen(opts); const handler = new MyHandler(); console.log("Tiny Redis 0.0.1"); console.log(`listening on: ${opts.hostname}:${opts.port}`); for await (const conn of listener) { (new RedisClient(conn, handler)).loop(); } } main() 

Then you can request your TINY command by:

redis-cli -p 6666 'tiny' 

And you will get "REDIS" as response.

It's not that amazing. But if you want your service talk redis protocol so that it can be accessed anywhere with any language, this may be a quick start in TypeScript/Deno world.
