get/set values from Uint8Array

It looks like this library mainly deals with strings, but I have some binary data that I'm storing in Redis. Is there currently a way to store/retrieve it, or is that not implemented?

Hi @shamblesides, thank you for reporting this issue! deno-redis does not currently support Uint8Array, but I think it would be nice to support it. 😃 I'll consider implementing it! 👍

Related to #133.

Sounds good! In the meantime I wrote my own custom minimal redis client using some of the code here as reference; hooray for the simplicity of RESP!

Limited support for getting/setting Uint8Array values has been added in v0.21.0!

You can use BulkReply#buffer (returned by Redis.executor.exec) to get Uint8Array values:

import { connect, replyTypes } from "https://deno.land/x/redis@v0.21.0/mod.ts";
import { assert, assertEquals } from "https://deno.land/std@0.91.0/testing/asserts.ts";

const redis = await connect({
  hostname: "127.0.0.1",
  port: 6379,
});
const encoder = new TextEncoder();
await redis.set("key", encoder.encode("hello"));
const reply = await redis.executor.exec("GET", "key");
assert(reply.type === replyTypes.BulkString);
assertEquals(reply.buffer(), encoder.encode("hello"));
