heyputer / kv.js Goto Github PK

NPM packages nowadays are developed using Typescript and type definitions are exported from the library so that methods and classes are typed. Since this library is entirely written in javascript, one of the following two can be picked to provide type definitions:

1. Convert the library to typescript and export interfaces
2. Submit type definitions to definitely typed repository so that consumers can add optional typings using npm install -D @types/heyputer__kvjs

Personally, and I believe most others as well, would like to see no. 1 picked and this library converted into a typescript one.

I think you mean to refence this.cleanupInterval?

Also, using a timer to cleanup expired keys is really inefficient and a huge performance suck--especially for a lot of ttl keys. I suggest at least making it optional, if not removing it entirely.

hello.
what is the use of this lib? i didn't understand properly.
(whats the difference between this and a simple value/variable in js?)

Hi

Is it supported CDN way?

Thanks

Saw your project on https://news.ycombinator.com/item?id=35608601 and the expires command seems wrong

Shouldn't kv.expire('username', 120, 'NX'); mean "Set expirity of username to 60 seconds if it has no expirity"? The documentation suggests "Set expirity of username to 60 seconds if username does not exist" which makes no sense (as the key does not exist and thus can't have expirity).

See redis docs for reference/suggestion https://redis.io/commands/expire/

‌‌‌It looks powerful, but is there a better way to compare its performance? Let's compare its performance with Redis, LocalStorage, and file storage in terms of storage and read speed, making it easier for everyone to choose.

It's often useful to be able to run a callback whenever a certain value changes. For example, maybe whenever the user's timezone changes, different parts of the app want to react in different ways to update clocks and other things.

For example:

const kvjs = require('@heyputer/kv.js');

// Create a new kv.js instance
const kv = new kvjs();

// Watch the key for changes
kv.watch('foo', value => {
	console.log('foo changed!', value);
});

// Set a key
kv.set('foo', 42);

// Console will log 'foo changed! 42'
