Paradigm inversion-write web applications in SQL instead of JavaScript
npm install sql-mvcParadigm inversion - write web applications in SQL instead of JavaScript.
If like me, you find the way web app development is done today as tedious, and wasteful, then join me
in creating a true "application programming language" (or DSL of you prefer),
as opposed to using a general purpose language (JavaScript) for writing applications.
In 1991 Oracle added a few extensions to SQL to create Procedural SQL, so now I have added a
few more extensions to SQL, to create QUery Application Language Extensions (QUALE) - it is that simple.
Recent change log: Added My-SQL and MS-SQL drivers. Updated Node version- caused a lot of breakage.
NPM shows thousands of weekly downloads, but I have not yet had feedback from the community, so please
if you have any questions, comments or even just want to say hi, please drop me a email for a personal response via
npm-support@sql-mvc.com
*Alpha version 0.0 Notice: When evaluating SQL-MVC keep in mind this project is still version 0.0.x- alpha/preview release.
A lot of stuff is not 100% polished or even to spec,
try and pick up the key points we are trying to demonstrate not shortcomings or bugs
(although all feedback is welcome). *

This is a complete implementation of todomvc.com functionality in 40 lines of code.

* Install instructions for Linux VPS from scratch - Install.md
The following may be broken as of June 2018 due to node changes.
* Windows - Windows install
* Cloud 9 IDE - Quick and easy to get going
* Existing node environment - in a fresh project directory just do: npm install sql-mvc
* Git hub https://github.com/quale-quest/sql-mvc
* SQL-MVC help and discussion mailing list : sql-mvc-talk
* Firebird Version 2.5
* MYSQL Version 5.7
* MSSQL SQL SERVER 12
* Soon - Postgres
* Soon - Oracle
* Soon - NuoDB
* The compiler takes your application code which is little more
than a few SQL statements, directives and properties and produces:
1. All the database code as a single stored procedure, to be run to produce JSON output.
2. a Moustache Template(Hogan) containing all the client side code to be filled with the JSON.
When the two are combined in the browser.
* The server node.js does very little other than pass JSON between the server and client.
* All the business logic remains in the database server.
* You have full control of the client side look, feel and behaviour, the
default framework and theme is just to give you a quick start.
* Write web applications with little more than a few SQL statements
* DRY (don't repeat yourself), Inheritance, Auto-Menus and more further reduces development time.
* Drop-in and plug-in modules allow easy use and customisation of common application functionality.
* Quick start with Platform + Framework + Themes + Modules + Demo's
* Build easily reusable custom widgets from complex HTML/JS/JQ
* Consistently customise the look and feel of your application widgets.
* Automatic hot code push during development (no reloading of pages with F5)
* i18n support and tools
* Security implied by design rather than explicit configuration.
* All database queries are amalgamated into a single database stored procedure call.
* the JSON from the database is retrieved in one BLOB (Less chatter to the DB).
* Almost no middle-ware processing.
* Exchange only JSON data elements across the wire.
* Build with Nodejs, SocketStream and Hogan templates to produce Single Page Applications.
* Cache client side code automatically, and update automatically when the server side changes.
* The page loads full visible content on first load - no partial view like waiting for multiple Ajax /ReST calls.
* Lazy loading of application client code while the user keys in his login information( if not cached already).
* Partial div(Divout) / records load/reload on Navigating / Saving or refreshing content.
* Lazy loading of obscured views or obscured rows in large data sets
* Client side caching of large datasets in reusable/relocatable chunks
* Subscribe to events to do partial refreshes when changes are posted to database objects by other users.
* Windows installer and development environment with JIT compiler and notepad++ with syntax highlighting.
* Database drivers available for Firebird SQL, support planned for : MySQL, SQL Server, Oracle, NuoDB.
* Planned support for JavaScript stored procedure engine, to enable no-sql, sqlite and off-line applications.
