hmset in typescript object

[sumanadak]

I tried to insert one simple object in typescript to ioredis hashmap. I define object like this

interface User {
name : string,
age :string
}

let newUser : User = {
name : "suman",
age :"34"
}
How do I write hmset command ?

There's an example in README: https://github.com/luin/ioredis/blob/main/examples/hash.js#L13. Prior v5.x.x, you also need to install @types/ioredis since v5.0.0 is the first version ioredis provides native TypeScript declarations.

Thanks a lot. I have seen this example . Perhaps I am not good with typescript, hence I am not able convert same example to typescript object type defination and call the API.

Could you please give an example which is written with typescript ?

I tried like this

Redis.hmset("user-hash", newUser) but typescript has an error...What could be the right way to put newUser object ?

[luin]

const redis = new Redis();

redis.hmset("hash", {
  name: "Bob",
  age: "20",
});

It works for me. Redis is a constructor so you need to follow the example to create an instance. Does it solve your issue?

Closing as this should be resolved in v5.0.0. Feel free to reopen if the issue still exists.

dear luin,
I am sorry for late reply. I was not in town. Here is my problem. I created constructor of redis and tried pass this typescript object like this
interface User {
name : string,
age :string
}

let newUser : User = {
name : "suman",
age :"34"
}
let redis = new Redis()
when I try to do like this redis.hmset("user-hash",newUser)
it gives me a error. Asking either string or map. Cant we pass object like this ? May be I am doing something wrong. Can you please give me some example with typescript object with hmset as example ?

Thanks for the follow-up. It's actually a limit on TypeScript side that you can't assign an interface to a record:

interface User {
  name: string;
  age: string;
}

let newUser: User = {
  name: "suman",
  age: "34",
};

const record: Record<string, string> = newUser; // Error here

ioredis expects a Record for the parameter so that's why you got the error. I'm working on making ioredis accept any interface as well.
