Sqoosel

SQL-based Application Framework for Node.js

Installation

$ npm install sqoosel --save

Usage

Define your SQL engine

var sqoosel = require('sqoosel');
sqoosel({
  // this function will be called in your every query to your SQL-based database
  query: function(exec) {
    pg.connect('postgres://postgres@localhost:5432/ci_test', function(err, client, close) {
      exec(err, client.query, close, client);
    });
  }
});

The passing callback exec will receive 4 arguments, then they are: exec(err, queryfn, closefn, client).

Define your schema and model

var sqoosel = require('sqoosel');
var UserSchema = new sqoosel.Schema({
  'id': sqoosel.types.bigserial().asPrimary(),
  'username': sqoosel.types.char(128).required(),
  'password': sqoosel.types.char(256).required(),
  'createDate': sqoosel.types.timestamp().setDefault('now()')
});
 
module.exports = sqoosel.model('user', UserSchema);

So close to mongoose ?

Using your model in your controller or anywhere that you want to use

var User = require('../find/your/model');
 
router.get('/register/', function(req, res, next) {
  var username = req.body.username;
  var password = req.body.password;
  // encoding your infomation or other business logic
  // ...
 
  User.insert({username: username, password: password})
    .exec(function(err, result) {
      // this function's arguments will depend on engine, your sql library, here we are using node-postgres
      if (err)
        res.status(500).end();
      else
        res.status(200).end();
    });
});

For more function-based SQL generation, you should move forward to brianc/node-sql

It's SQL database, we need to apply your schemas, very simple to call createReadStream with your model

Now show you howto generate .sql init script:

// load your models
var User = require('../find/your/model');
User.createReadStream().pipe(fs.createWriteStream('/path/to/your/sql/file'));

Then you will get the .sql script like:

CREATE TABLE IF NOT EXIST user(
  ...
);

How to pipe multiple models to one file? dominictarr/event-stream is the anwser:

var es = require('event-stream');
es.merge(
  Model1.createReadStream(),
  Model2.createReadStream(),
  ...
).pipe(fs.createWriteStream('/path/to/your/sql/file'));

If you want to check your SQL schema string, toString are available for you as well:

var Model = require('...');
console.log(Model.toString());
