Liqueed Project (1)

Filed under: Express, JavaScript, Liqueed, MongoDB, NodeJs, Open Source Projects — ajlopez @ 6:36 pm

Next Post

Today, I want to present the Liqueed Project, see repo at:

https://github.com/liquid-co-ops/liqueed

It is a web application based on an idea by @acyment, read post:

http://blog.agilar.org/index.php/2014/04/30/leancoops-first-draft/

The basic idea of the application is to help teams that are developing something in the way that Cyment suggested, on the issue of allocation of shares on the project. For several months, the application (code, backlog, ideas, implementation, hosting and others) has been putting together by a “liquid” team (with entry and exit of people)

In this series of posts starting today I want to discuss interesting technical issues raised by the project. For today, I commented that:

– It is a Node.js application, exposed to the web using Express. Bringing the programming language is JavaScript.

– In addition to some internal administration pages with MVC, has an API exposed, exchanging JSON.

‘- There’s an app Single Page which is what would have to use the end user to view projects, voting, distributions of shares and to enter new ratings

– Most of the code was written using the workflow of TDD (Test-Driven Development). Even the first code implemented the model in memory, allowing easier progress on the implementation of use cases, without bothering about persistence (even the SPA client can run without having a walk server)

– A few months ago, we added persistence with MongoDB. We could use another database, relational perhaps. We are not taking advantage of the facilities to handle documents MongoDB yet. Only chose it for its ubiquity in development platforms and different Node hosting services.

– Some weeks ago, we added Istambul for code coverage.

– When TDD tests for pure code began to be long, we created a textual DSL (Domain Specific Language) that allows us to write text files for more complicated functional tests.

– Begin to add tests of SPA (Single Page Application) using Zombie

And there are more details and topics to comment, in the upcoming posts.

Stay tuned!

SharpMongo (2) a REPL

Filed under: C Sharp, MongoDB, NoSQL, Open Source Projects, SharpMongo — ajlopez @ 7:15 pm

Previous Post

I’m working on my document in-memory store project, written in C#

https://github.com/ajlopez/SharpMongo

It tries to implement the same operations as MongoDB: to have document bases, collections, documents, dynamic objects, etc. But with a difference: all is in-memory, and by now, in the same process. Persistence will be added as a plugin.

One of the tools I wanted to build is a REPL (Read Eval Print Loop), a console program that emulates the main functions of the MongoDB console client. The MongoDB program talks againts a server. SharpMongo, in the current version, only works in the same process memory, no persistence is implemented, yet.

The project is SharpMongo.Console. It compiles an assembly named sharpmongo.exe. You can launch it from command line:

SharpMongo 0.0.1
> show dbs
> show collections
> use foo
> show dbs
foo  

Now, we are in a db (document base), named ‘foo’. We can create a collection inserting dynamic documens, in a JSON-like format:

> db.people.insert({ Name: 'Adam', Age: 800 })
> db.people.insert({ Name: 'Eve', Age: 700 })
> show collections
people  

We can find the documents in a collection:

  > db.people.find()
{ "Name": "Adam", "Age": 800, "Id": 4d802e11-a038-468e-bd26-38e96ad6f7d8 }
{ "Name": "Eve", "Age": 700, "Id": b29917f1-70f1-4f6c-95bb-f789fa9bf3c0 }  

We can find documents, filtering them using a criteria, expressed in a dinamic object as first parameter (a la query by example):

  > db.people.find({ Name: 'Adam' })
{ "Name": "Adam", "Age": 800, "Id": 4d802e11-a038-468e-bd26-38e96ad6f7d8 }  

We can insert more documents:

> db.people.insert({ Name: 'Cain', Age: 600 })
> db.people.insert({ Name: 'Abel', Age: 500 })
> db.people.find()
{ "Name": "Adam", "Age": 800, "Id": 4d802e11-a038-468e-bd26-38e96ad6f7d8 }
{ "Name": "Eve", "Age": 700, "Id": b29917f1-70f1-4f6c-95bb-f789fa9bf3c0 }
{ "Name": "Cain", "Age": 600, "Id": a5a3e1af-7e5c-4c16-829e-c07f94bc8697 }
{ "Name": "Abel", "Age": 500, "Id": c1da0055-8ded-4540-876f-5c032f514ed3 }  

We can insert and remove documents:

> db.people.insert({ Name: 'Pluto' })
> db.people.find()
{ "Name": "Adam", "Age": 800, "Id": 4d802e11-a038-468e-bd26-38e96ad6f7d8 }
{ "Name": "Eve", "Age": 700, "Id": b29917f1-70f1-4f6c-95bb-f789fa9bf3c0 }
{ "Name": "Cain", "Age": 600, "Id": a5a3e1af-7e5c-4c16-829e-c07f94bc8697 }
{ "Name": "Abel", "Age": 500, "Id": c1da0055-8ded-4540-876f-5c032f514ed3 }
{ "Name": "Pluto", "Id": 0561864a-470a-4437-9467-773ffb5a438a }
> db.people.remove({ Name: 'Pluto' })
> db.people.find()
{ "Name": "Adam", "Age": 800, "Id": 4d802e11-a038-468e-bd26-38e96ad6f7d8 }
{ "Name": "Eve", "Age": 700, "Id": b29917f1-70f1-4f6c-95bb-f789fa9bf3c0 }
{ "Name": "Cain", "Age": 600, "Id": a5a3e1af-7e5c-4c16-829e-c07f94bc8697 }
{ "Name": "Abel", "Age": 500, "Id": c1da0055-8ded-4540-876f-5c032f514ed3 }   

There are missing parts, the most important one could be the support of operators in query objects, that could allow us to apply more complex criteria, beyond equality, and operators in the update operation. All will be added using TDD, as usual.

Keep tuned!

I’m exploring NoSQL, specially MongoDB. In a non-public project, my customer is using MongoDB, and I’m writing an in-memory alternative, an extension of my open source project Memolap. I like to implement in-memory storage, so I decided to write a MongoDB-like in C#, work in progress:

https://github.com/ajlopez/SharpMongo

As usual, it’s been written using TDD workflow:

I’m implementing the same ideas in JavaScript/Node.js, check:

https://github.com/ajlopez/SimpleMongo

The current status of SharpMongo hasSi ven el estado actual de SharpMongo, tiene:

– Class project SharpMongo.Core
– Test project SharpMongo.Core.Tests
– Class project SharpMongo.Language, where I’m implementing a simple language for a console program
– Test project SharpMongo.Language.Tests
– And the console program SharpMongo.Console

There are some base classes:

Engine has a list of DocumentBase. A DocumentBas has Collections. The documents and dynamic objects:

A Collection contains DynamicDocuments. A DynamicDocument is a DynamicObject (a key-value dictionary) but with an additional property Id.

I have already implemented the Collection methods:

– Insert
– Find (with query and projection)
– Remove (with query)
– Save (with and without Id)
– Update

And the console project has many implemented commands. Next steps:

– Operadores en Find
– Count
– Nested DynamicObjects and arrays in a DynamicObject
– Pretty print in console program

Then, I should manage concurrency, or at least, serialize the updates (execute them one by one). I could add:

– Server that receives line commands via TCP, with plain JSON commands to be executed, and returning results in JSON

– Clients in C#, JavaScript, PHP?

Keep tuned!
