Readme
Node-viewmodel is a node.js module for multiple databases. It can be very useful if you work with (d)ddd, cqrs, eventdenormalizer, host, etc.
$ npm install viewmodel
var repo = require('viewmodel').read;
repo.init(function(err) {
if(err) {
console.log('ohhh :-(');
return;
}
});
Make shure you have installed the required driver, in this example run: 'npm install mongodb'.
var repo = require('viewmodel').write;
repo.init(
{
type: 'mongoDb',
host: 'localhost', // optional
port: 27017, // optional
dbName: 'viewmodel', // optional
collectionName: 'dummy',// optional and only if you directly want to use a collection, so repo.extend() is not necessary...
timeout: 10000 // optional
},
function(err) {
if(err) {
console.log('ohhh :-(');
return;
}
}
);
var dummyRepo = repo.extend({
collectionName: 'dummy'
});
dummyRepo.get(function(err, vm) {
if(err) {
console.log('ohhh :-(');
return;
}
vm.set('myProp', 'myValue');
vm.color = 'green';
dummyRepo.commit(vm, function(err) {
});
// or you can call commit directly on vm...
vm.commit(function(err) {
});
});
// the query object ist like in mongoDb...
dummyRepo.find({ color: 'green' }, function(err, vms) {
if(err) {
console.log('ohhh :-(');
return;
}
// vms is an array of all what is in the repository
var firstItem = vms[0];
console.log('the id: ' + firstItem.id);
console.log('the saved value: ' + firstItem.color);
});
// the query object ist like in mongoDb...
dummyRepo.get('myId', function(err, vm) {
if(err) {
console.log('ohhh :-(');
return;
}
console.log('the id: ' + vm.id);
console.log('the saved value: ' + vm.color);
});
dummyRepo.get('myId', function(err, vm) {
if(err) {
console.log('ohhh :-(');
return;
}
vm.destroy();
dummyRepo.commit(vm, function(err) {
});
// or you can call commit directly on vm...
vm.commit(function(err) {
});
});
myQueue.getNewId(function(err, newId) {
if(err) {
console.log('ohhh :-(');
return;
}
console.log('the new id is: ' + newId);
});
var repo = require('viewmodel').read.create();
repo.init(function(err) {
if(err) {
console.log('ohhh :-(');
return;
}
});
