CanJS 4 & DoneJS 2
- debugging tools (hello can-debug)
- streaming property definitions (goodbye listening to
- cli commands:
donejs addheroku, travis, travis-deploy-to-firebase, & travis-deploy-to-heroku
CanJS debugging guide
The new debugging guide has lots of tips and tricks for debugging observables, modifying view-models in your console, debugging stache templates, and even creating cool graphs like this one to understand the relationships between your observables:
CanJS forms guide
One of the examples: how to bind to checkboxes with stache converters.
Improved error messages & handling
Yesterday, Matthew blogged about the improvements to error handling in DoneJS. Check out that post for our philosophy on errors and how the changes to these DoneJS and StealJS packages will make your development workflow smoother:
- firstname.lastname@example.org & email@example.com: better 404 error messaging
- firstname.lastname@example.org & email@example.com: formatted HTML page for errors (with live-reload!)
- firstname.lastname@example.org: better error handling during live-reload
- email@example.com: explains 404s for modules
- firstname.lastname@example.org: points out errors in your package.json
- email@example.com: adds error handling for live-reload
- firstname.lastname@example.org: improves the errors for dev bundles failing to load, mismatched package versions, malformed JSON
- email@example.com: nicer messages for syntax errors in ES and CommonJS modules
- firstname.lastname@example.org: explains why an @import statement fails
Here’s an example of one of those improved error messages—trying to can-import a file that doesn’t exist:
Justin’s hosted a bunch of live-streams on YouTube:
- CanJS 4.0 Overview
- CanJS Widgetry #5 - Rich Text Editor
- How it Works: Observables and Computes built with Queues and Trees
- How to use can-queues.logStack to debug your CanJS application
- How it works: can-observe
We run a community survey every six weeks to get a feel for what everyone would like Bitovi’s open source team to prioritize (sign up here if you’re not on our list).
Here are the proposals that have been most voted for on our surveys; we’ve already started working on some of them, while others we plan on starting in the coming weeks:
- can-query / make it easier to configure and understand can-set
- Create DevTools for CanJS
- Improve routing to components (will serve as a foundation for adding a routing guide and testing guide)
- Minimize bundle size with tree-shaking & Make CanJS Tree-Shakable

A little info about Maarten: he’s from the Netherlands and works as a freelance consultant. His first exposure to StealJS was through an article on CSS-Tricks about the modlet workflow.
He’s off to a quick start with steal-sass 1.1, which supports Node 6+ and includes some PRs that had gone unmerged while the project was unmaintained. Welcome to the team Maarten!
