  • with real-time functionality by simply referencing variables
  • build schemas with simple json objects (no more complicated ORMs)
  • that scale to 100k+ users without hosting your own servers
  • on Linux, Mac, or Windows
  • in any editing environment you prefer

Documentation is available at http://www.dobi.io

use asset-wrap's new pre-processing to simplify .exports

right now styles needs .app.exports .page.tour instead of just .exports

right now classes need class exports.Page extends lt3.Page instead of just class exports.Page

as always, need to make sure to remain backwards compatible, so previous format should still work as expected

Pair Programming: Design Discussion

Currently, the LT3 development kit can update your browser view when code is updated. This is great for when a developer is working on issues alone, but it'd be great to allow developers to pair program remotely.

This ticket is meant to be a discussion on how to implement this feature. It would involved using firebase in a similar way to sync code between two consenting users.

Topics for discussion include

how the two users connect to each other behind the scenes
how to store the data in firebase
what the UI should look like for connecting
what does the full process look like? if one developer makes a change, does it just update the UI of the other programmer, or does it also update the other programmer's source code?
could we make a model work where n number of users could connect together? what makes sense?

@jasongornall - comment with any other ideas

Strange caching issues present when doing sets

example call:
db.sites.find({_id:"532b9cea5bf249e601fe5aa8"})[0].get("created").set("w") works

result:
creates is not update... wait some amount of time and see it updated. maybe a caching issue?

expected:
cache is broken and results are updated

make an lt3 shell

would be useful to be able to run database commands quickly from the console

cache bust not working correctly

getting some duplicate key errors, which means cache bust on query isn't working as expected

dobi 2.0.0

get rid of workspace model and take a more npm-esque approach

  • dobi init will be used to create a new package anywhere you want.
  • dobi install will pull in external dependencies into local dobi_packages directory

todo before this can happen

  • add ?version= parameter to override the live version of a site
  • get production to load packages from database instead of disk
  • dev compiler will need to be able to compile local files, and then load dependencies from dobi_packages instead of assuming everything is in a workspace "pkg" directory

Add package types to lpm init

Allow user to specify "theme", "app", or "library" when initializing a new package and set up new package files and config accordingly.

add /packages section to the site

should query packages_config collection

> db.packages_config.findOne({}, {'files.data': 0})

OSX: preventing crashes on local development

"lt3 dev" server sometimes crashes on OSX with node 0.8.x on an Abort 6 error. Updating to 0.10.x may prevent some of that as there have been updates to watch for errors like this in some core libraries. The main issue is that the server should restart in the case of a crash like this.

Let's research/discuss the best way to handle this.

one option is to use the built-in cluster to listen for failure and spawn a new process. I haven't tested cluster out on windows, so not sure if we'd run into issues there.

Another point of discussion would be how to re-auth the user after a crash. Right now authentication happens when connecting in the browser, maybe we should consider using the local auth token stored in .lt3_config on server startup.
