Acl node.js module

Question

I'm trying to use acl module for user permissions.

I've installed the module with npm install acl --save .

Added these lines to code:

var acl = require('acl');
var redisClient = require('redis');

acl = new acl(new acl.redisBackend(redisClient, 'session'));

acl.allow('member', 'events', 'view');

Received this error:

TypeError: Object #<Object> has no method 'multi'
    at Object.RedisBackend.begin (workspace/server/node_modules/acl/lib/redis-backend.js:23:23)
    at Acl.allow (workspace/server/node_modules/acl/lib/acl.js:231:37)
    at Object.<anonymous> (workspace/server/app.js:24:5)

    at Function.Module._load (module.js:312:12)
    at Module.require (module.js:364:17)
    at require (module.js:380:17)

Any ideas?

The issue was that the redisClient was not properly initialized.

//this line did the trick
var redisInstance = require('redis').createClient(6379, '127.0.0.1', {no_ready_check: true});

and then

acl = new acl(new acl.redisBackend(redisInstance, 'session'));
