How to use mget with a variable of type array

[awerhane]

I'm assuming this is just a syntax issue, but I can't seem to use mget with a variable.

If I have a variable
const keys = ["record1", "record2", "record3"]

The following will return 0 records
const records = await tedis.mget(keys)

But if I do the following, I will get 3 records.
const records = await tedis.mget("record1", "record2", "record3")

I'm not sure of the syntax when using a variable.
I even tried the following, but I still get no results.
const keyString = '"record1", "record2", "record3"'
const records = await tedis.mget(keyString)

Any help on how to execute an mget request with a variable (preferably an array) would be appreciated.

Thanks!

The current version does not support the kind of call method you said, you can refer to the documentation about the use of mget. tedis later upgrades will add this overload method, you can use the new feature of es' Spread syntax to implement the requirements.

const keys = ["record1", "record2", "record3"]
const records = await tedis.mget(...keys)

This codes does not work in TypeScript:

    const clientHashes: string[] = clientFiles.map(f => f.hash);
    let serverPaths: string[];

    // Error: ts(2556) A spread argument must either have a tuple type or be passed to a rest parameter
    serverPaths = await db.hmget(filesKey, ...clientHashes);

    // I should write code like this: 
    if (clientHashes.length == 1)
        serverPaths = await db.hmget(filesKey, clientHashes[0]);
    else if (clientHashes.length > 1)
        serverPaths = await db.hmget(filesKey, clientHashes[0], ...clientHashes.slice(1));

Why hmget function has field parameter?

  public hmget(key: string, field: string, ...fields: string[]) {
    return this.command<Array<string | null>>("HMGET", key, field, ...fields);
  }

=>

  public hmget(key: string, ...fields: string[]) {
    return this.command<Array<string | null>>("HMGET", key, ...fields);
  }

I think above two codes is same. Is there any compatibility problem?
