redis-hmsetex

hmsetex lua command for redis clients

DEPRECATED

Since Redis 4.0.0, hset has become variadic, so use it instead

hmsetex redis command

Sets the value of a hash key and updates the expire date at the same time.

HMSETEX key 1 firstname walter lastname white

In the example above, key key expires in 1 second.

Install

$ npm install --save redis-hmsetex

Usage

The easiest usecase is to use with https://github.com/luin/ioredis as follows:

const Redis = require('ioredis');
const redis = new Redis();
require('redis-hmsetex').install(redis);

Additionally, the necessary information is exported:

const Redis = require('ioredis');
const { name, lua, numberOfKeys } = require('hmsetex');
const redis = new Redis();
redis.defineCommand(name, { lua, numberOfKeys });

Then, just run like any other command:

redis.hmsetex('some_key', 1, 'firstname', 'walter', 'lastname', 'white');
setTimeout(() => redis.hgetall('somekey'), 1100); // At this point, null is returned

Tests

There are unit tests and integration tests. Needs Node 6+ to run. The integration tests require redis to be installed.

npm test:unit
npm test:integration
npm test # run both tests
