Rapid

Rapid is an ORM-ish api for redis, currently backed by node_redis. Rapid is very much a work-in-progress and represents a day or two of work, so feel free to contribute!!

Installation

$ npm install rapid

Examples

Source:

var rapid = require('rapid');

var User = rapid.model('User', {
    first : { type: 'string', required: true },
    last  : { type: 'string', required: true },
    email : { type: 'string', format: 'email' },
    age   : { type: 'number', min: 1, max: 120 },
    image : { type: 'binary' } 
});

var tj = new User({
    first: 'TJ',
    last: 'Holowaychuk',
    age: 23,
    email: 'invalid'
});

tj.save(function(err){
    // access err.record and err.property
    console.error('error: %s', err.message);

    // Fix and re-save
    tj.email = 'tj@vision-media.ca';
    tj.save(function(err){

        // Grab user by id
        User.get(tj.id, function(err, user){
            console.dir(user)
            process.exit(0);
        });
    });
});

std{err,out}:

error: User email format is invalid

[User
  id: '841c71863a7cfce63b5393b4f64b8814'
  first: 'TJ'
  last: 'Holowaychuk'
  email: 'tj@vision-media.ca'
  age: 23
  image: undefined
]

Validations

The following validations are currently supported:

• require: ensures that a property value has been assigned
• min: ensures numeric value or string length when assigned is >= min
• max: ensures numeric value or string length when assigned is <= max
• format: ensures string format via the given RegExp or canned format such as "email".

Types

Each rapid "type" is tasked with coercion, "loading" redis Buffer data into a native JavaScript equiv, as well as "dumping" JavaScript values to a Buffer object for storage within Redis. Current supported are the following types:

• binary
• string
• date
• json
• number
• boolean (aliased as bool)

Testing

Launch redis:

$ nohup redis-server &

Run the tests:

$ make test
