Node Roundup: Bedecked, Knockout.sync.js, express-promise

Bedecked

Who wants to write presentations in Keynote or PowerPoint? No one! That’s why Justin Russell made Bedecked (GitHub: jtrussell / bedecked, License: MIT, npm: bedecked):

Bedecked

Who wants to write presentations in Keynote or PowerPoint? No one! That’s why Justin Russell made Bedecked (GitHub: jtrussell / bedecked, License: MIT, npm: bedecked):

A small module for quickly and simply authoring snazzy presentations in Markdown - or Jade, or vanilla HTML. Inspired by hackynote (thiagofelix/hackynote), Bedecked splits your Markdown into slides and spits them out as a single html file that you can share with Dropbox, S3, or whatever you like.

The command-line tool allows you to transform Markdown files into presentations. It uses stdout, so you can redirect the output into a .html file.

It can also run as a server which supports live reloading.

Knockout.sync.js

Knockout.sync.js (GitHub: imrefazekas / knockout.sync.js, License: MIT, npm: knockout.sync.js) by Imre Fazekas adds syncing to Knockout, supported by a Node server. This allows data to be persisted to a server and shared between clients as desired.

Timestamps can be used to allow clients to respond to outdated data, and Socket.IO is used in the client.

express-promise

express-promise (GitHub: luin / express-promise, License: MIT, npm: express-promise) by Zihua Li is middleware for folding repetitive asynchronous operations into leaner synchronous-style operations.

This is the kind of thing you’re probably used to writing:

app.get('/users/:userId',function(req,res){User.find(req.params.userId).then(function(user){Project.getMemo(req.params.userId).then(function(memo){res.json({user:user,memo:memo});});});});

But with express-promise you can do this:

app.use(require('express-promise')());app.get('/users/:userId',function(req,res){res.json({user:User.find(req.params.userId),memo:Project.getMemo(req.params.userId)});});

The readme has more documentation, with examples for Mongoose and Sequelize.
