(ANOTHER) simple Node.js module to connect and send commands to Redis using promises with configurable environment variables, build on top of Node Redis.

• Features
• How to use
• Reference
  • Connecting to Redis
  • getAsync and setAsync

• Connect easily to Redis using promises and async/await
• Use environment variables or an options object to set connection parameters
• Call async commands like GET and SET using getAsync and setAsync methods

$ npm i -s redis-simple-connect

const connectRedis = require('redis-simple-connect');

const client = await connectRedis();

When calling the main exported method from module, you may use environment variables or an options object.

The method returns a RedisClient object from Node Redis, so you can call this class methods and commands.

const client = await connectRedis();

This way the module will try to obtain the main connection parameters (host, port, password and database number) from the following variables: REDIS_HOST, REDIS_PORT, REDIS_PASSWORD and REDIS_DB.

• Note that port, password and database number are not required options.

If you want to add a prefix to the variables, you may use the envPrefix parameter:

const client = await connectRedis(_, 'MYAPP_');

// This way the method will look for `MYAPP_REDIS_HOST`, `MYAPP_REDIS_PORT`, etc.

const client = await connectRedis({
  host: 'redis.domain.com',
  port: 8654,
  db: 7,
  password: 'abd132be1323115bd51afbfaba'
});

This module injects two methods to the RedisClient class: getAsync and setAsync.

Both are promisifed versions of the respective methods get and set.

const value = await client.getAsync('key');

await client.setAsync('key', value);
