redis-adapter 🔌

This is simple Redis client adapter with promises.

Methods and usage

• Create connection

const Redis = require('redis-adapter');

const client = new Redis({port: 6379, host: '127.0.0.1'});

client.connect()
    .then(() => {
        console.log('Hooray!');
    })
    .catch(error => {
        console.log('Connection failed!');
    });

client.on('end', () => {
    console.log('Connection closed')
});

• Connection with prefix

const client = new Redis({port: 6379, host: '127.0.0.1', prefix: 'prefix'});

• Call methods

client.call('smembers', 'blocks').then(blocks => {
    console.log('List of blocks:', blocks);
});

• Use shape for plain shapes:

client.shape({
    blocks: ['smembers', 'blocks'],
    hashName: ['hget', 'data', 'name'],
    range: ['zrange', 'logs', 0, '+inf'],
}).then(({blocks, hashName, range}) => {
    console.log('blocks set:', blocks);
    console.log('hash key "name" value:', hashName);
    console.log('range:', range);
});

• Instant multi

client.multi([
    ['smembers', 'blocks'],
    ['hget', 'data', 'name'],
    ['zrange', 'logs', 0, '+inf'],
]).then(([blocks, hashName, range]) => {
    console.log('blocks set:', blocks);
    console.log('hash key "name" value:', hashName);
    console.log('range:', range);
});
