QEWD: Rapid REST APIs + persistent JSON

This might be of interest, particularly those who want to quickly and simply develop REST APIs that require a database on the Raspberry Pi See: https://github.com/robtweed/qewd For info on installing and running a demo of the integrated persistent JSON database in action, accessed via REST APIs: htt...

Re: EWD.js: Node.js/Web-socket framework

To answer your question about the scenario you present, the answer is yes. Indeed this is precisely the kind of scenario for which I was keen to ensure that EWD.js provided a packaged solution. 1) The ewdgateway2 module's master Node.js process provides a secured (and configurable) socket listener p...

Re: EWD.js: Node.js/Web-socket framework

The engine that underpins EWD.js is already is a Node.js module: npm install ewdgateway2 ...as explained in the documentation EWD.js is effectively the syntax and techniques you use to exploit that engine. You also have to understand that EWD.js applications run in the browser but instead of using H...

Re: EWD.js: Node.js/Web-socket framework

You could ask the same of any framework. Perhaps you don 't need it, but others may find it's a real productivity gain and allows them to create much more maintainable, modularised applications. I've outlined what I believe are its benefits in the documentation Anyway it's all free open source stuff...

Re: mongoDB Package

See Appendix 4 in: http://gradvs1.mgateway.com/download/EWDjs.pdf I found a pre-built set of binaries for MongoDB and the above document explains how to install them - about 5 minutes and you'll be up and running with MongoDB. Then read the rest of the EWD.js documentation above and you'll be able t...

Re: EWD.js: Node.js/Web-socket framework

A follow-up. I've now added appendices on how to run EWD.js with MongoDB on the Raspberry Pi. See Appendix 4 & 5 in: http://gradvs1.mgateway.com/download/EWDjs.pdf So now you have a complete framework for building MongoDB-based WebSocket / browser-based client-server applications, all running on you...

Re: EWD.js: Node.js/Web-socket framework

By the way this may help to explain the architecture and mechanics behind EWD.js. The only difference on the Raspberry Pi is the noDB.js emulation of the database.

Re: EWD.js: Node.js/Web-socket framework

Are Mumps databases relevant outside healthcare and should you consider them as a viable alternative to other "mainstream" databases and open source DBs? Most definitely: it's a sadly unknown and poorly-understood, yet incredibly powerful technology. See: http://www.mgateway.com/docs/universalNoSQL....

Re: EWD.js: Node.js/Web-socket framework

Developing with EWD.js just involves creating HTML pages and JavaScript files - use any IDE you like, there's lots out there. For debugging/testing your "back-end" Node.js/JavaScript code, see: http://robtweed.wordpress.com/2013/11/20/testing-your-ewd-js-back-end-logic/ For a quick description of wh...

EWD.js: Node.js/Web-socket framework

I've recently ported EWD.js to the Raspberry Pi - very quick and simple to get up and running. EWD.js provides a 100% JavaScript development environment for browser-based client/server applications. It's entirely web-socket based, using Node.js and socket.io to provide the "back-end" for your applic...

Re: node.js with socket.io ?

Here's an example of some pretty awesome web-socket and inter-machine communication fun that I was able to get working on a Raspberry Pi in less than an hour by using EWD.js. Full source code and pointers to the appropriate documentation are provided in the article, so hopefully you'll be able to ge...

Re: node.js with socket.io ?

I see my EWD framework mentioned here a few times. I've now ported it to the Raspberry Pi for anyone that might be interested. See: http://robtweed.wordpress.com/2013/11/12/ewd-js-for-the-raspberry-pi/ I'll be adding an Appendix on how to set it up on the Pi in the EWD.js documentation: http://gradv...

Re: Database port to Pi: looking for technical volunteers

Please don't use the Raspberry Pi for anything that someone's life may depend on such as medical information. As fond as I am of the device, its is nowhere near enterprise grade equipment. :-) Agreed. Don't worry, the intention isn't to run a hospital on a Raspberry Pi! However, as a means of learn...

Database port to Pi: looking for technical volunteers

A project has started up to port an interesting Open Source database called GT.M to the Raspberry Pi. For some of the significance of this project and some background to it, see: http://robtweed.wordpress.com/2013/03/26/mumps-the-proto-database-or-how-to-build-your-own-nosql-database/ The Raspberry ...
